I have gsr motor rebuilt. I went with itr pistons{11.3 to 1} kept my rods,lightened flywheel,erics racing compition ported and polished head,skunk2 valves,springs and retainers.Then something came up and I was short on funds and wasn't able to get my cams , intake manifold,throttle body and injectors. My ? is can I still safely supercharge if so how much whp can I get if its tuned good?
