Just cruising the junkyard (Pic-A-Part) and found 3 GM 3.8 M90 superchargers. I'll show how fast and easy it is to pull one of these and how little you will pay for one or two.
The Gen 2 Supercharger is also known as the Eaton M-62 (62 referees to cubic inches of air movement per revolution). It was used in 1992 and 1993 cars.
The Gen 3 Supercharger is also known as the Eaton M-62. It was used in 1994 and 1995 cars. It has epoxy-coated rotors and a larger inlet diameter.
The M-90 (90 referees to cubic inches of air movement per revolution) was introduced in 1996 for the debut of the L67 Series 2 GM 3800 engine.
Gen V Eaton is a more efficient M-90. The Gen V M90 appeared on the scene in Grand Prix Comp G beginning in 2004, this redesigned M90 had a more efficient airflow and longer rotors than the Gen 3 causing it to run much cooler than its predecessor. The Gen V bolts right up to the LIM of a Gen 3 except for a slightly larger outlet opening. Different throttle body bolt patterns make an adapter plate necessary to swap from Gen 3 to Gen V. The Gen V retained the 3.8" diameter pulley as well.
