Edelbrock E-Force 122 Superchargers

BACK BY POPULAR DEMAND... We first launched this E-Force system back in 2007 and it was one of our best sellers. Unfortunately it had to be discontinued... but now its back and even better! The E-Force 122 Supercharger Kit is a positive displacement supercharger that is capable of producing 500+ horsepower on a small-block Chevy engine. This system utilizes the Eaton® H122 rotor assembly for maximum efficiency in a compact package. The compact design may potentially fit under the hood of most muscle car and street rod applications. Testing resulted in a peak of 507 horsepower and 487 ft/lbs of torque @ 5 psi on a 350 c.i.d. with 9.5:1 compression. The E-Force 122 is designed for use with factory style belt and pulley configurations. Will not work with aftermarket serpentine pulley systems and will require the use of a long-style water pump. Each kit includes the supercharger assembly with Eaton internals, intake manifold, drive pulleys, belt, gaskets and all necessary items for ease of installation. Does not include carburetor, so you can use your carburetor of choice.
    Features Include:
  • Includes an Internal Bypass Valve that virtually eliminates parasitic loss under part throttle and deceleration, requiring less than 1/3 horsepower at 60 mph cruise
  • Easy-to-follow installation manual with no fabrication or special tools required
  • Self contained oil system with 100,000 mile service interval (no drilling or plumbing required)
