I bought my stang off a guy who already had a supercharger on it and i have done the rest of the mods. The supercharger only pushes 4-5 lbs boost and it looks like the pulley is part of the s/c and cant be removed. Its an old paxton oil self contained unit. I was wondering can i change the crank pulley to a smaller pulley for more boost or am i better off buyin a whole new set up and purchase a Procharger. If i do this though wont i have to move my battery and other things. Let me know your opinions and what to do thanks.
