someone told me to change the pulley or belt on the supercharger to make it kick some serious ***, anyoen done this or know what hes talking about? would it chew up gas?

He meant putting a smaller supercharger pulley on to make it spin faster, make more boost, thus more fuel, and more power. Best bang for the buck on a supercharged car. Don't go too small or heat will be a problem. With a 94, put on a 2.5" pulley. See if you can find one form a junkyard off a 92/93 SSEi (it was stock size those years, then SC was revised for 94/95).

It'll use some more fuel if you have a heavy foot.
