How much boost for a stock engine
I have a '00 Trans Am and I am making 6 lbs of boost now on a basically stock block. Racetronix Fuel pump with hotwire kit, 42 lb. Injectors, Vortech supercharger with aftercooler, full exhaust, fast intake. The rest of the fuel system is stock and right now I am making about 470 rwhp. If I wanted to change out the pulley to a 2 3/4" that would put me up around 8 lbs. of boost. Is that too much on my motor?
