Superchargers

Roots Style Superchargers

ERD has been involved in the developement of the PSI roots 14-71 blower since 2004. With numerous dyno pulls and modifactions ERD, in conjunction with Roger at PSI, has developed a supercharger that has proven itself to be competitive in IHRA and NHRA Pro Modified.

The ERD/PSI supercharger has an ajustable injector spacer that was developed in house and is unique in the industry because of its ajustablilty for different overdrives. While being primarially developed for legal 20% overdrive it delivers a power & torque curve that is necessary to be a contender at every nation event.

The ERD/PSI supercharger has several number one qualifiers and National Event victorys to date. As well, our supercharger was used to set an IHRA 1/8 mile world at Toronto Motorsports Park.
