M90 vs M62 Eaton Blower

[dcbrufan]

Hi! Anyone tried installing a M90 blower into their M42 engine? Is it better compared to the M2 since its able to push more air into the manifold. Cause I would need to modifiy the M2 pulley in order to hit 10psi. A stock M90 may be able to do that w/o any mods.

Thanks!
