just about to make my purchase on a kenne bell and wondering which pulley i should go with from your guys experience/opinion? 7psi, 8psi?.... obviously i know lower is safer but i want the highest/safest amount of boost. engine is stock internals with aftermarket intake and complete exhaust. thanks guys!

My buddy has a 03 with a stock supercharger and runs the 2.4 pulleys after the car was tuned and all it dyno'd at 478 rwhp. He dyno'd at 536hp on a 50 shot.
