Topic: Rotrex Superchargers

wondering who is running any sort of rotrex S/C and how they like them. also i want to put a c38-91 in my car and was wondering what its max PSI that its capable or producing

We have done a couple of them here now, and the only other person I know that has done one is SCdyne.

On the Rotrex site they list the max pressure ratio of the C38/91 as 2.94, which means at standard pressure you would be looking at a max of 28.5 psi and 84lb/min of air. How much power do you want to make? That is a pretty big supercharger and way overkill if you want to be in the 500hp range.

i would like to be at 400-450 WHP range and be streatable with little issues

basicly i understand the engine will need a build. the other issue i would be worried about is the transmission and rear end

I would look at the C38-71 for the power you want to make.
