Superchargers

Series 1 L67 motors were equipped with an Eaton M62 supercharger.
These superchargers were 62 cubic inches in volume (1.016 liters).

Series 2 L67 engines were equipped with a generation 3 Eaton M90 supercharger. The M90 is a 90 cubic inch supercharger (1.47 liters) in displacement. On the L67 it was fitted with a 3.8“ diameter pulley and produced about 8 psi of boost from the factory.

In Australia there were several rear wheel drive vehicles that were equipped with an M90 as well. These versions of the M90 have a slightly different throttle body opening to allow it to be fit in a longitudinal orientation.

Series 3 L32 engines were equipped with a generation 5 Eaton M90 supercharger. This is sometimes referred to as a “GenV” supercharger on many forums. This was also equipped with a 3.8” diameter pulley but it was slightly more efficient than the generation 3 m90 that the L67 was equipped with.
