Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

Joe West wrote

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Simple Low-Cost Charger for Keeping Your Battery in Peak Shape

This simple 12-volt automotive battery boostertrickle charger provides a choice of charging rates to suit battery condition

Set to FULL CHARGE It wlll restore apartIally discharged battery overnight when set to TRICKLE CHARGE It will maintain the battery at peak capacity foran extended time period A built-In LED glows only when the charger Is delivering current to the battery The circuit Is shown below

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

Joe West wrote

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

Joe West wrote

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

Joe West wrote

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

Joe West wrote

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

Joe West wrote

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Simple Low-Cost Charger for Keeping Your Battery in Peak Shape

This simple 12-volt automotive battery boostertrickle charger provides a choice of charging rates to suit battery condition

Set to FULL CHARGE It wlll restore apartIally discharged battery overnight when set to TRICKLE CHARGE It will maintain the battery at peak capacity foran extended time period A built-In LED glows only when the charger Is delivering current to the battery The circuit Is shown below

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Simple Low-Cost Charger for Keeping Your Battery in Peak Shape

This simple 12-volt automotive battery boostertrickle charger provides a choice of charging rates to suit battery condition

Set to FULL CHARGE It wlll restore apartIally discharged battery overnight when set to TRICKLE CHARGE It will maintain the battery at peak capacity foran extended time period A built-In LED glows only when the charger Is delivering current to the battery The circuit Is shown below

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge

Simple Low-Cost Charger for Keeping Your Battery in Peak Shape

This simple 12-volt automotive battery boostertrickle charger provides a choice of charging rates to suit battery condition

Set to FULL CHARGE It wlll restore apartIally discharged battery overnight when set to TRICKLE CHARGE It will maintain the battery at peak capacity foran extended time period A built-In LED glows only when the charger Is delivering current to the battery The circuit Is shown below

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

From jmdavis5unityncsu edu Subject Re Lower Shrouds To joewestprimenetcom (Joe West) Date sent Wed 27 Dec 1995 004411 -0500 (ESn Copies to corvairthunderboltmitreorg

Joe West wrote

gt Is it beneficial to run a Corvair motor in the Hot Arizona sununer with thegt lower shrouds removed or ill it cause more damage One thing is for suregt the cooling system is open loop with the lower shrouds removed and I hategt it when things are open loop)

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Simple Low-Cost Charger for Keeping Your Battery in Peak Shape

This simple 12-volt automotive battery boostertrickle charger provides a choice of charging rates to suit battery condition

Set to FULL CHARGE It wlll restore apartIally discharged battery overnight when set to TRICKLE CHARGE It will maintain the battery at peak capacity foran extended time period A built-In LED glows only when the charger Is delivering current to the battery The circuit Is shown below

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge

Technicai Topic

Submil1ed by Rex Brown as presented at our last reUiar meeting

At the April meeting j had a Tech Tip about keeping your cars o il temperature cooler and was asked if I cou ld share the tip The Tech Tip was given to me by Lew Rishel from San Diego at the 1995 MinishyConvention in Portland We were looking at mv Twin Turbo 65 Monza and I as telling him about how the oil alwas runs hot Lew asked if I had restricted the fl ow of oil thru the exhaust push rod drain tubes He pointed out that the exhaust stacks in the cylinder heads were notched to allow clearance for the drain tubes With this arrangement heat from the exhaust would be transferred into the oil running thru the drain tubes

The restrictor that j came up with was 7 16 SAE flat washer The outside diameter was just slightly larger than the inside diameter of the cyl inder head end of the push rod tube The diameter of the hole in the flat washer was slightly larger than the slot in the push rod guide plate To correct the outside diameter of the washer j slipped the washers on the end of a 38 drive extensio n and rotated them against a grinding wheel until they would juSt tap into the end of the drain tube I then brazed the washer in place to make sure they wouldnt move

I havent yet had a chance to try this out but it looks like it should help Always be sure to check for proper push rod clearance when assembling your engine j was also told that there are a couple of different washer styles available so look until you have one that will work and always make sure the hole is at least the slze of the slot of the guide plate

This always seems to come back to the underl~ing question that is (unfortunately) not usually asked How hot is normal and how hot is too hot Fortunately for us G-middot was worried about this question too and so spent a lot oftime and money finding the answers

Testing of the 1960 model showed an absolute worst-case head temperature of 465 F at full throttle at 60 mph sustained (l00 F ambient temperature) Oil temperature was 280 F under these conditions This was with the most efficient fan and the most efficient folded-fin cooler and the early model thermostat system which controls cooling ~ flow with an inlet throttle rather than exhaust damper doors

The oil temperature cited was regarded as excessively high and the designers hoped that this particular set of conditions would not nonnally occur Under more normal operating conditions oil temperature hovers in the 190shy250 F range on this type of engine which is squarely in the temperature range recommended by engine oil manufacturers

The head temperatures were within design parameters I will note that these are comparable to head temperatures I have observed in a wide variety of healthy air-cooled engines from snowmobiles to general aVlallOn engmes

Design changes over the years increased specific output and (usually) reduced cooling capacity Fans were changed twice but the first design remains the most efficient air pump

GM ran a series of tests in 1966 on the eve of introduction of the first 50 state smog pump equipped Corvairs They found that the smog pumpair-conditioning combination was a guaranteed aluminum foundry and that

3

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

operating temperatures ith a smog pump on an nonnal engine were excitingly high The immediate result of these tests was that air-conditioning was not available ith a smog pump

Th is infomlation is in the CORSA Tech Guide which is copyrighted so I cant reproduce the article middoterbatim I can quote the germane part however

So what does all this mean

I) A head temperature as high as 475 F is not WlJeasonably high Racing snomobiles I didnt get warned until the heads got over about 500 F and this is in an engine that suffers heat related failure problems long before a Corvair does temperature ise because of poor piston cooling

2) GM cited heaJ temperatures under bocst in turbo cars in excess of 500 F as nonnal Ths makes me a little weak-kneed but turbos can be extremely durable if properly maintained

3) The most fragile engine head-temperature ise is the 140 so you should make more effort to keep I~O heads cooler Having said that Ive observed that 140s ith head temperatures around 450 on a hot day tend to be quite durable All of this assumes a calibrated gauge I have used thermocouples for the purpose

4) Theres no substitute for head temperature and oil temperature gauges I have put these on my Greenbrier because it gets pushed harder than the 140 Corsa thermally (no kidding I assure you) I worry much more about my stock 140 Corsa running too cold in winter in NC than I do about it running too hot in swnmer Yes we have temperatures in excess of 100 F here as well

5) On the Greenbrier I have never seen head temperatures in excess of 450F nor oil temperatures in excess of 250 F Ths includes doing some things intentionally just to see how hot it would get and nonnal things like towing trailers at 70 mph in 95 F temperatures etc I hae blued the crossover pipe and very thoroughly b2ked the paint onto the lower shrouds but the engine never showed any sign of distress It now has 50000 miles on it and passes all the nonnal health tests with flying colors

6) Put side-shields on the oil cooler if youre not using a folded-fin (which is superior anyway and comes with them)

7) Id worry about oil temperature long before bead temperature unless you want to drive a turbo smog or air-ltonditioned car hard (mountain climbing tQing) in the gt100 F regime Then Id worry about both And the best way to worry is knowledgeably Put on gauges of known accuracy before you decide you need to change GMs design

8) Ergo I use the lower shrouds on both cars because slow warm-ups are much more harmful to any car than a 6 higher head temperature The only time I omit them is when in the exhaust packing tightening stage after doing exhaust work

Simple Low-Cost Charger for Keeping Your Battery in Peak Shape

This simple 12-volt automotive battery boostertrickle charger provides a choice of charging rates to suit battery condition

Set to FULL CHARGE It wlll restore apartIally discharged battery overnight when set to TRICKLE CHARGE It will maintain the battery at peak capacity foran extended time period A built-In LED glows only when the charger Is delivering current to the battery The circuit Is shown below

Circuit The output of transformer T is rectified by diodes DI and D2 Pulsating DC is deltvered to the battery via an output cord to the Cigarette lig~ter receptacle In the vehicle SwItch S Is used to choose between FULL CHARGE (about one ampere) and TRICKLE CHARGE (about 50-mAgt The Indicator LED IS In sOles WIth Its current ltmlter R4 nIB fuse protects against short circuits

Construction The entire circuit can be rrl)unted in a small metal box using multi lug terminal striRs to support the components l)oint-to-point wiring can be used The AC line cord and the output cord should be passed out of the box via grommetted h(lles A plug that fits the cars Cigarette lighter receptacle shoud be connected to the output cord Make sure the polarIty Is correct

Operation Plug the AC line cord into a conv~)t outlet and plug the output cord into the Cigarette lighter receptacle Select either a FLU or TRICKLE char-e via S and veriFy that the LED glows In either position of S If the LED does not glow clean the contacts on the plug and the Cigarette lighter receptacle (disconnect the battery ground first) and try again I f this Falls check for a wiring error Should the batery be completely discharged (dome light does not light) use the TRICKLE CHARGE positlo of S for one tl) two hours Less than 6 to 9 volts from the battery at the end of this time means that It must be replaced If the voltage Is about 12 volts place S In the FULL CHARGE IXlsltlon After a couple of day switch S to the TRICKLE CHARGE pOSition to maintain the battery at Full charge
