This is the blower that came on the Series III 3800 Supercharged engines.  The outlet is about 20% larger than a Gen III Eaton M90's, and the inlet is 75mm.  If you are doing this supercharger as an upgrade for an engine that originally had a Gen III, we recommend pairing this blower with a 75mm Northstar throttle body, and a pcm tuned for the bigger throttle body/MAF.

Blowers are sold in good used condition with good bearings and supercharger coupler.

Gen V blowers are considered a custom order, and are nonrefundable.
