Further more in a supercharger application the frame size of the supercharger has a tighter window of boost in which is its effective range. for the jl/jt sized maggie superchargers and the rotrex superchargers you are going to be under 20psi of boost in most applications. Lowering compression...
Lowering Compression reduces the efficiency of the motor. For example:
on a VQ37 (Nissan V6 which is similar to this motor). We have an 11:1 compression ratio and a displacement of 3.7L. At 20-21 psi the motors make about 800-900whp. Now drop that compression down to say 10:1 and it now...
