If you were going to change out the forced induction I believe you would have more potential at less cost to go turbo than to change to a centrifugal supercharger. My experience with these type of superchargers is that they are common in the aftermarket as they are cheaper than screw types. I don't know if they are more efficient. Heat is your enemy with any FI. Why not spend your money with more intercooling since you would have to that anyway?
