The Powerdyne Model BD11A Supercharger Unit is a belt-driven supercharger designed for individual use. This product includes only the supercharger unit, and no additional items are included. It is manufactured by Powerdyne, a brand known for producing high-quality superchargers. Unit just had bearings rebuilt, was removed from 2000 Camaro SS due to repeat boost leaks from substandard piping used on this particular install, supercharger unit it's self is in excellent condition with a set of fresh bearings ready for its next gig. This unit was designed for and installed on 98-02 Camaro/Firebird, and should also be compatable with most LS engine setups, assuming there is sufficient mounting/plumbing space.
