    Thumbs up P1sc and 3" pulley, anyone done it?

    Has anyone or does anyone know of someone who has instlled a 3" pulley on the P1sc? Would there be any issues other than fuel and electronic ugrades , which I intend to do, with this diameter size pulley? I was told that the smallest diameter that should be used is the 3.6" pulley. Any smaller and I would risk blowing the seals. I really don't see how it would be a problem because the P1sc is rated to handle 30lbs of boost. Thanks for any info. :D

    I have 3 in. pulley on mine & I haven't blown a seal yet. I've had it on the car for a few months already, I ordered it through this site.

    My seals blew out with the 4.5" pulley on. When they are ready to go, they go which was 12 1/4 mile passes.
