At any rate, don't get too caught up on the numbers. Adding a supercharger was one hell of an upgrade. The car is an absolute beast. At this point, the main thing holding it back is traction
Thanks man. If I go to 3.6 pulleys, will I need anything more than my LS9 injectors on the fuel side? I know a BAP is a good insurance policy, but at what level are these "necessary"?
