Hi,

I am trying to setup a used SoK supercharger and I need some help trying to figure out some of the calculations involved.

Almost everything I read talks about calculations based on how many PSI of boost you are running. However I am missing something fundamental. How do I figure out how many PSI of boost I will have?

I have the compressor map which relates pressure ratio to air flow, and the basic specs of the supercharger.

I would like to know how many PSI of boost I will be running if I spin the SC at:

1.685 * engine rpm

1.764 * engine rpm

1.973 * engine rpm

2.142 * engine rpm

Thanx,

Kirk
