I know that if i do a pi head swap on my 98 gt that i will have a boost in compression to 10.1 so can i still supercharger and if not would it be better to just not worry about heads and cams and just supercharge my car?
You should still be able to supercharge the car. You may not be able to run as much boost as you would if you stayed npi. Still i think you should make more power if you did the pi swap and supercharged the car with a little less boost then if you left the npi parts on and supercharged it.
