Hi Hectori, I believe that the boost level from a supercharger is set by the pully ratios used as opposed to a variable boost control on a turbo. I'm after information in the form of: Do I need to lower cylinder compression or increase the head bolt strength or can I just strap in on? It is an EATON supercharger which I think is a "constantly-engaged" unit and it has come off a Mini Cooper S. Cheers. C.
