Solving problems...adding value...satisfying customers. Welcome to the world of the Eaton Supercharger.


The Eaton Supercharger is a highly engineered design of a Roots-type positive displacement pump with no internal compression.

Each of the two tri-lobed rotors have been twisted 60 degrees into a helix--to reduce noise and improve volumetric (air-flow) efficiency--and coated to enhance intermesh and further improve efficiency. The rotors are mounted to shafts driven by ultra-precise timing gears connected by a poly V-belt to the crankshaft of the engine.

Key unique features of the Eaton Supercharger are the inlet and outlet air ports. Years of computer design and laboratory testing have optimized their placement and shape for improved adiabatic and volumetric efficiency, power consumption, and dynamic pressure variation.
The Supercharger incorporates a bypass system to reduce air-handling losses when boost is not required, resulting in better fuel economy. The system's bypass valve is a throttle-plate design that can be actuated electronically or by a vacuum diaphragm.
The Eaton Supercharger is exceptionally compact and can be mounted in a very low profile directly to the intake manifold of the engine. In some current applications, an engine with an Eaton Supercharger is actually lower in height than the same engine unsupercharged.

The Eaton Supercharger does not require exhaust gas flow to operate, thus minimizing underhood temperatures and eliminating the need for any external liquids to cool system components. To ease installation and maintenance, the Supercharger is entirely self-contained and self-lubricated.

Why an Eaton Supercharger?
1. How does a supercharger work? A supercharger is a positive displacement pump. Its purpose is to supply an excess volume of intake air to the engine by increasing air pressure and density in the intake manifold. The supercharger is matched to the engine by its displacement and belt ratio, and can provide excess airflow at any engine speed. This concentrated charge of air provided by the supercharger results in a more powerful combustion stroke in the engine's cylinders.

2. How is a supercharger different from a turbocharger? A supercharger is connected directly to the crankshaft by a belt unlike a turbocharger which is driven by exhaust gases. The improved horsepower and torque, at lower engine rpm's, is obtained by pumping extra air into the engine in direct relationship to crankshaft speed. The positive connection yields instant response, in contrast to turbochargers, which must overcome inertia and spin up to speed as the flow of exhaust gas 'increases. The supercharger is a way to get around 'Turbo lag". The lubrication system also differs in that, the supercharger is self-contained whereas the turbocharger requires engine oil.




3. How did Eaton become involved in supercharging? In 1949, toyed with a helical rotor supercharger and even built a 75-cubic inch displacement prototype. This supercharger was 'Temporarily" set aside since improved performance was achieved through larger displacement engines. The late 70's spurred new interest in supercharging since gasoline prices were driven up due to the energy crisis. Eaton continued to improve its design and addressed issues such as noise and durability. It was through these many design improvements and an eye toward manufacturing that allowed Eaton to begin working with Ford on the 3.8L engine in 1994. Vehicle demonstrations, durability and noise were refined as well as a cost effective manufacturing process which allow the Eaton supercharger to be installed on the first production supercharged vehicle since 1957 The 1989 Ford Thunderbird SC was awarded the Motor Trend Car of the Year award. In addition, three engineers were also recognized for their work on the supercharger having been awarded the Society of Automotive Engineer's first Henry Ford 11 Award for Engineering Excellence.

4. The roots supercharger has been around for a long time. How is the Eaton supercharger different? The Eaton supercharger is essentially a Roots blower pump, with one substantial design wrinkle: Each rotor has been twisted 60 degrees to form a helix. The two counter rotating rotors have three lobes, which intermesh during operation. These twisted rotors, along with specially designed inlet and outlet port geometry, help to reduce pressure variations resulting in a smooth discharge of air and a low level of noise during operation.

5. How long has Eaton been manufacturing superchargers? Production for Ford Motor Company began in 1989 with General Motors production beginning in 1992.

6. Are there other supercharger manufacturers? Other than the aftermarket, there are currently no other supercharger manufacturers in the United States.

7. What are the benefits of the Eaton supercharger? 1) Patented technology to reduce noise, 2) Proven manufacturing capability, 3) Packaging flexibility, i.e. reduced package size, 4) Self-contained lubrication, 'i.e., no external oil connections to the engine, 5) Bypass system used for controlling non-boosted conditions resulting in better fuel economy, 6) Competitive pricing.

8. How much power does the supercharger add? This is dependent on the size of the supercharger and also the size of the engine. Typical power improvements in the range of 25% to 50% are riot uncommon.

9. How efficient is the Eaton Supercharger? Typically, the volumetric efficiencies are around 90%. (Performance curves, including Volumetric efficiency, are available upon request.)

10. Can all engines be supercharged? Yes, supercharging is very compatible with all engines whether the engine be two or four valves/cylinder, gasoline, diesel or 2 stroke.

11. Are special engine modifications required for installing the supercharger? This is dependent on the level of power increase desired and the given engine design.

12. Are superchargers noisy? The Eaton supercharger system incorporates a specially designed bypass valve, which is actuated by a vacuum motor near the throttle body and recalculates the supercharger air flow when boost is not required. During typical driving conditions, the engine is under boost around 5% of the time, which means the remaining 95% of the time the engine is under vacuum, allowing for better fuel economy and a quieter ride. In addition, the helix angled rotors, along with specially designed inlet and outlet port geometry, also reduce pressure variations resulting in a smooth discharge flow and a lower level of noise during operation. Careful attention to the techniques used in installing the supercharger also plays a major role in reducing the noise emitted by the supercharger.





13. Is the product durable, safe? The durability of the Eaton Supercharger was the first criteria which was addressed during the designing of the supercharger. Dedicated engineers with backgrounds in compressors, gearing, tribology and metallurgy, as well as thermal and structural analysis enabled Eaton to find solutions to many durability concerns. In addition, customer durability testing employed strict criteria increments of torque and speed. Successful completion of numerous 500 hour durability tests established a firm grasp on achieving a durable product. In addition, numerous vehicles have successfully completed 100,000 mile, OEM, vehicle durability. Improvements in bearing and seal designs also aided in a product which meets all OEM durability criteria. Safety, in turn, follows suit once durability is achieved. The OEM criteria for safety must be designed into the product prior to supplying any manufactured component.

14. Is the Eaton Supercharger easy to service? The supercharger is serviced as two units, the nose drive and the supercharger itself. The rotors are supported by ball bearings in front and needle bearings at the rear The drive gears are pressed into place and require precise timing to achieve proper rotor to rotor clearances. Therefore, the supercharger is replaced as a unit, and is not serviceable. The supercharger also has a self-contained oiling system that does not require a fluid change for the life of the vehicle.

15. What type of fuel is required? What about fuel economy and flexible fuels? Supercharging is compatible with all types of fuels including flexible fuels. Fuel economy is not compromised, as described above in item #12, when utilizing the bypass system in conjunction with the supercharger.

16. Is the supercharger recyclable? How does supercharging affect the environment? All supercharger components are recyclable.

17. What is the cost of a supercharger? This is dependent on the size of the supercharger required and annual volumes.

18. Does Eaton see supercharging in the future? With the continued interest in performance and the desire to maintain fuel economy, supercharging could be the ideal product of the future. Using a supercharger to increase power on a smaller displacement engine, in turn achieving the performance of a larger engine, but not compromising fuel economy seems too good to be true - but that is what the Eaton supercharger provides.

19. Is the supercharger available for aftermarket applications? To date the Eaton supercharger has been designed for specific OEM applications. This is due to the fact that each engine application has unique hardware installation requirements and the design criteria of the supercharger is matched to the specific engine. Recent interest has been shown in this market and has resulted in four sizes of Eaton Superchargers being offered by Magnuson Products.

















CUSTOM GEAR COVERS & DRIVE EXTENSIONS

The new Magnuson Products custom gear cover with drive extension gives complete flexibility to aftermarket applications. This gear cover and drive extension allows supercharger placement where you want it.

The gear cover is cast and machined to Eaton's precise standards. The oil fill may be placed to your needs. The supercharger is coupled to the nose cover using Eaton's 3 pin gear to cover assembly. The 3 pin hub has a 48 spline drive and is carried with large roller bearing. Once the exact drive length is determined the drive housing and shaft are cut to length. Then the forward bearing and sea] are installed with the shaft in place. This system allows a full selection of pulleys for your needs. (The 3/4" diameter - 48 running spline shaft, 3 basic lengths, and hub/pin assemblies are stress-proof material.)

EATON SUPERCHARGER SERVICE
Our first business responsibility is service on all Eaton Supercharger products, including by-pass valves, manifolds and other support items.

We service all the assemblies separately and can supply them that way, or as complete superchargers. complete means the front cover assembly (nose drive), rotating groups (rotors, gears, bearing plate, bearings and seals timed up) and rotor case (case with rear bearings). All rebuilds reflect the newest Eaton technology as far as parts are concerned. For instance, all rotor groups starting in 1994 have coated rotors, so if we service a 1989 SC Thunderbird supercharger, it will have the upgraded coated rotors.

Ford has used the Eaton M90 supercharger on Thunderbird SC models since 1989. Note: 1989 through 1993, first generation ... 1994 through 1995, second generation.

GM - Buick 3.8 Vs has been using an M62 Eaton Supercharger since 1992 on special models, first generation. It was upgraded in 1994, second generation.
