A BRIEF GLIMPSE AT

nhauser, The Greatest Name Sn Racinge

One of the few pioneer performance equip rnent manufacturers that has heldout against the acquisition and contrd by major conglomerates, Offenhauser Sales Corp, mntinues to expand by innovat~on and magination In their products for perlorrnance and economy-minded oonsurners.

"A rare bfend of tradition and ~nnovation" is more than a catch phrase. It's a way of do~ng busness. If yw were to check into a typical day's operation at the Offenhauser plant, you rnight see an c~der of cast aluminum heads tor '39-'48 Ford flatheads being processed for shipping. And in the new research facifity you might find engineers running a test cycle on the new dyno to determine erntssion lsvels of a new style manifold.

This Issue of the Offenhauser catalog contains the latest manilold3 for foreign and domestic cars includmg the famous Oual Port 360" and Dial-A-Flow as well as accessories fw pre-World War II Ford Flatheads!

While some mandokd manufacturers wncen- trate on raclng efforls with "give away offers" and wild performance claims. Offenhauser has maintained the policy that their products will be made to the highest qualiy and performance standards and be available to everyone on an equal basis. Perhaps that's one of the reasons that Offenhauser rnanifotds are seen on more strmtrods. Ahot rodderthat builds a car from the ground up takes pr~de in his workmanship and that same pride carnes over to the equipment he chooses for hts rnachlne.

Offenhauser innovation rn the freld of recrea- tional vehides has h e n publidzed by wery RV magazine In the business. The Dual-Port 360" is the perfect choice for economy as well as performance for 4-WD r~gs, campers, motwhornes, vans, and passenger cars.

And consider the fact that menhauser offers for mini-cars more manifolds than all of the other man~fold makers combtned! Small englne and compact cars are a fact of life in loday's economy. Offenhauser accurately prmcted this trendseveral yearsago and started develop~ng a tine of perfwrnance rntake man~folds for 4,6, and V-6 englnes. These power boosters offer max low end torque and detrver efficiency that can increase gas mileage. There are 2 and 4 bbls in the patented famous Dual Port design, 360" Equa-Flow, and speclal C Man~tolds. Check thls catalog for complete listings.

When tt comes to all out competition, Of- fenhauser innovation has come up with the Port-0-Sonic and the Super-Sonic, not to mention the Turbo-Thrust h~gh rise maniidd with lnd~vldual runner design.

Innovation IS the product of people with imaginatron. A cornb~nation of people with skills, curiosity, and irnag~nafion at Offenhauser makes it happen

Fred C. Offenhauser has h e n designing and manuiacturing performance equipment fm over 40 years. From the start of his racing career at theorrgrnal Oyl engine plant in 1933 topresident

The Often hauser Research 8 Development facility contalns the most sophisticated instrumentation in the performance industry. DigFtal and chart readouts assure accurate checks on every phase of testfng. Over a quarter of a million dolFars were spent to make this lacilfty the best in the industry.

of Qffenhauser Sales Corp., his achievements and firsts in the science of automotive engineer- ing are a result of technical insight and irnagina- tion and the desire for 'a better solution."

The vital link between the factory and consumer is the sales network. Inchargeof sales is third generation Fred C. Offenhauser Jr., better known as Tay. He contributes to the success of the company by communicating with dealers and dislributws thrwghout the world

In charge of Production and Quality Control, Jim Offenhauser organizes and dlrects a large staff of skilled workmen as he works to maintain the Offenhauser reputation ror first class technology and prduct quality.

While innovation and tradition are Important ingredients In the manufacturing af products at Offenhauser, technology plays an equally Important role. Even as you read this catalog, Offenhauser engineers are working on new designs for better performance, fewer emissions, and improved fuel economy. Over a quarter of a million dollars worth of testing equipment has been installed in a special test center at Offenhauser. Everything from a simple horsepower bakeline curve to a 24 hour readout on emissions, fuel-flow, exhaust temperature, gaslair velocity and torque can be accomplished with thls test center.

Many Offenhauser equipment customers have wondered why more of the top name drivers don't use or endorse Offenhauser manifolds. Tha fact is, many of the top names do indeed usa Offenhauser manifolds. BUT, we feel that money spent to secure these endorsements ~ o u l d be better put to use in designing a manifold that will outperform all others. The real winner is you! When you buy a manifold with the Offenhauser name on it, you're getting the latest and best manifold that men and machinerj can produce. Over SM] manifold llstlngs appear In this

catalog. They are organizd according to manifold style and represent 40 years of research and development. The Intake Manifold Coverage Chart on page 3 will help you identify which manifold styles are available for your engine and where they can be found. The selection chart on page 4 shows torque and horsepower ranges for every popular type of manifold style. Be sure to refer to lt and you'll order the manifold best suited for your intended use.

Mfenhauser contlnues to work on more projects that are based on future needs as we see them and as you see them. No matter what those needs turn out to be, you can bet that Offenhauser will meet them with the traditional innovation that has made us the Greatest Name In Raclng for wer 30 years.

HOW THE DUAL PORT INDUCTION SYSTEM WORKS

The Dual Port 360 can best be described by saying tt's actually two separate rnan~folds in one. The entire rnantfold is divided from the base of the carburetor to the head flange. The percentage of separation ir of cwrse a closely guarded secrer on this now patented des~gn and it varies f rom engine t o englne

In operation, the pr i rnav mixture is fed Into-the bottom runners and the engine opera ares on this smaller port unt i l driver or engine demand cuts in the secondaries - the top part. Many good things happen wi th th is in. duc t~on system. I n the Dhal Port, the prlrnary system further restricts t he alr f low after passing the carburetor and Increases it to the "speed of sound." Thts means that wen at low engine rpm (see dyno charts) we're getting near perfect aerodynamic efflclency, ar trens- lated - more HORSEPOWER! Thts extra horsepower on the prlmarles comes from a more perfect mixture rnovlng at near sonic speeds. a larger volump passing the intake valve and greater turbulence in the combus- tion chamber for a highly eff~cient use of fuel. The primary system (see cutaway illustration). being on the bottom unlquely provides two layers of manifold casting and a h ~ g h speed mlxture flow which acts as a perfect ~nsulator far the secondary runners. And since she

secondaries are insulated from engine heat. this means that when cut in the secondary mixture wil! be "cold" and "dense" - a further increase in performance. Then, when the secondary mixture gets to the end o f the runner it IS picked up and "rammed" into the combustiun chamber by the sonic veIoc$ty of the primary port. Again, an ald in pwslng a greater, colder and more dense airlfuel mix- ture past the intake valve and settlng u p an $deal combustion chamber cond~t ion t o in- crease horsepower output.

All the dyno tests so far - using a great variety of englnes. have ahown substantial horsepower increases over t h e ~ r entlre rpm range. By measuring the "brake spec~f~c" (see dyno chart), which rr the amount o f fuel con-

sumed per horsepower, per hour. further proves the value of the highly efficient Dual Port system as lela fuel was used to gain more horsepower.

Due to the high efficiency of the Offen- hauser Dual Port Induction System. I? has also proven itself capable of greatly reducing ex- haust em~ssions in tests af an elaborate facility In the rntd-west. Th15 makes Offenhauser the FIRST speed equipment manufacturer ro produce a product that reduces exhaust emie srons yet increases horsepower!

We have intake manifolds for all of the most popular mini engines: Datsun, Toyota, Courier, Mazda, Luu, Vega, Pinto, Capri, Jeep, etc. Most of the manifolds are available in 2 different designs (Dual Port and "C" Series) and can b e drilled a t the factory to accept either the stock carb or papular Holley OR Weber replacement carbs. These pages clarify manifold style differences and available accessories. Complete manifold listings begin on page 10.

DUAL PORT SERIES The patented Dual Port is our S f REET PERFORMANCElECONOMY DESIGN. A detailed explanation of the Dual Pert system appears on page 6. In the Mini's, the prlmary section boosts the fuel mixture to nearly the "speed of sound", about 3 times faster than normal velocity. This positively gives each cylinder a ful l fuel charge every t ime to smooth out the power stroke. When engine or driver demand cuts in the secondaries. a cold (over 30' colder) and dense mixture i s sent down the secondary runner to be rammed in to the combustion chamber by the sonic f law of the primary runner. This adds up to: 15 - 30% more horsepower, quicker thrott le response, extended RPM range, better gas mileage, quicker starting, reduction of exhaust ernis- sions. The two barrel mini Dual Ports come standard (order "DP") to accept the stock 2 stage carburetor. Howwer, as an alternative, most can be drilled a t the factory to accept the Holley 5200 series (order "DPH") or the Weber 32/36 series (order "DPW"] a t no extra charge.

"DPH" ACCESSORIES (HOLLEY 5200) Some Mini Dual Ports (including Datsun, Toyota. Chevy Luv and Ford Courier), which have been drilled for the Holley 5200 a r b w ~ l l usually require a 1" carb spacer Mo. 61 76 i n order for the carb linkage to clear the manifold.

OFF ENHAUSER takes the "EM and "X" out of the performance equation and replaces ~f with P.OS. (PORT 0 SONIC). Notice how closelv the power curves parallel each other ro 4000 RPM. This is 'typical of an independent runner open chamber manifold with the OLD style fixed runner sysrern. OFFENHAUSER'S advanced tech- nology has developed a sonic air flow pattern In the w n that obviously makes the difference where rt really counts, 4000 to 8000 RPM.

Oyno results are w i th a Chevrolet 327 C.I.D. engine which is modified for racing. using a modified Hollev 600 cfm carburetor.

SUPER SONIC MANIFOLD* Designed for Holley 4500 Carb Competition Track & Drag Racing Allows carburetor to function properly a t all stages of R.P,M. Paravanes stabi tize air flow Totally New Concept

* Tried and Proven A refinement of the highly successful

Port-0-Sonic, the Super-sonic is the first manifold ever designed to take ful l advantage of

the Holley 4500 carb. From the mounting pad to the giant plenum through the big runners, the Super-Sonic is designed to produce

the power. The secret i s the use of 4 paravanes at the bot tom of the plenum to direct the gadair mixture through the runners in an even distribution pattern w i th a

minimum turbulence factor. Recommended carb is Holley Part *R-7320AAA. Torque and Power Range Information on page 4.

360" EQUA-FLOW HIGH RISE SINGLE QUAD MANIFOLDS' IT'S A PROVEN FACT: Looking back, over fifteen years ago Offenhauser broke away from the old 180" design and introduced a 360" design manifold which other manifold manu- facturers are now following.

You get full benefit of improved fuel passages on every single engine stroke, there is no down time with a 3600 - your engine operates at full capacity a t all times. So-called 180" manifolds operate on a part- time basis due to the fact that one side of the rnani- fold is "down" while fuel is delhvered to the other side of the engine.

. - Exclusive plenum chamber design of Offenhauser 360" Equa-Flow Manifold wipes out flat spots in a l l RPM ranges. Gives you smooth . . . unrestricted flow of fuel . . . continuously. Each cylinder receives equal fuel flow without interruption or oscillation. You get vibration-free smoothness and power rammed distribution through balanced efficiency. Hands you more power off the line . . , a fantastic top end improvement. Dyno, Street- Strip Proven. Test results show a 20 H.P. increase at 6500 RPM over competitive manifolds.
