But I doubt it would make the car any faster. When I put my 3.4" pulley on when I just had a powerlog instead of the headers my car actually felt slower on top than with my 3.8" pulley on 18* of timing. Sure my car felt stronger from a dig but that feeling disappeared once I hit 2nd and starting getting a ****load of KR. There is no sense in doing a mod if it's not going to make your car much if any faster, all while increasing the risk of eventually chipping a piston.
