well depends on what u are running I have upgraded my cams new pistons and lighter pully and a lighter flywheel with duel exhaust 2.25" from a header and i have a supercharger i have yet to have any problems. but i hear you can do less with a supercharger than a turbo. but if you want full performance i would upgrade and lighten as much as possible. but cams and pistons and lifters possible new crank would be a good start and would help with power.
