I bought a used supercharger kit last year. Its a Vortech S Trim. Iv done a ton of reading about superchargers cause they are all new to me. Right when I thought I knew all I need to know I was showing my bud my kit and he said, nice you have a bypass valve and a powerpipe.
Come to find out its a Maxflow Race Bypass Valve.
I thought all superchargers had a bpv. If they dont have a bpv, what do they have?
I looked up the bpv and it said 1-8psi. Wth does that mean? I cant run no more than 8psi?? Im lost. Anyone care to give a lesson?
