Author : Willwren Specs for the Eaton M62 & M90 Superchargers **all revs listed are SC revs** M62 Max boost: 10psi/460cfm @ 14000 rpms M62 hp gain: 7hp @ 4000 rpms, 36hp @ 14000 rpms M62 Operating temperature: 135° @ 4000 rpms, 180° @ 14000 rpms ________________________________________ M90 Max Boost: 10psi/520cfm @ 12000 rpms M90 hp gain: 10hp @ 4000 rpms, 42hp @ 12000 rpms M90 Operating temperature: 160° @ 4000 rpms, 190° @ 12000 rpms ___________________________________ From these specs, it's easy to see why the M90 pulley is larger. It reaches max boost of 10psi at 12000 rpms, rather than 14000 rpms like the M62. Hence the larger pulley resulting in lower drive rpms. M62 specs are in general, as the Gen 2 Eaton for 92/93 was slightly less efficient than the Gen 3 Eaton for 94/95. These M62's are specific for 91-93 and 94/95, and are not interchangeable without a lot of work. |
