    not really sure what it is exactly you want to know. there are no “series” of superchargers for the 3800 engine. There is one standard supercharger that is used on all gm cars that have the supercharged engine from 92-03.

    its probably a 3800 series II. i had a 1992 pontiac bonneville that had a 3800 series engine and shortly after that it was series II.

    Eaton manufactured that supercharger for the GTP series 4, Buick Regal GS. The Bonneville has the same supercharger after 1999. It was not until the 2004 the series 5 was used
