Jack 5.75 , 7500rpm. It shows 55K rpm already which is over Vortechs spec of max 52K rpm and only making 9-10psi.
Why do they state the V3 can make 21psi when the rpm max is 52K doesn't make any sense?

Boost is a measure of restriction. V-3 has different specs, and consequently different rated CFMs. As a result, boost will vary according to the CFM of a supercharger and volumetric efficiency of a car. Hopefully it answers your question.
