    need help,need pully

    hi guys....

    I have a p1sc on my lt1 camaro 1995 since last month. due to detnation problems i had to rebuilt the engine and lower the compression . now the 8 psi is not enough and i need to raise the boost and change the pully and the belt , but i could not find any info. about that in the internet .
    if any one can help me to know a site that has those pullyes so i can order and know the size and price for them?

    thanks in advanced.....:weird:

    Your car takes what ATI calls a "D" series pulley. They rate the pulleys by diameter, not #'s of boost. Check the diameter of your pulley, sometimes it's satmped in the face of the pulley. The basic rule of thumb is that every tenth of an inch is equal to about 1 psi of boost. So, if for instance, you have a 4.5" pulley that is making 5psi and you want 10 psi, then you need to get a 4.0" pulley.
