Need pulley for P1SC

**ccarpenter85** · 08-09-2011, 06:16 PM

I am looking for a 7 to 8 lb pulley for a ATI P1SC for a 2000 Trans am. I am no having very good luck finding one. If anyone has any suggestions I would greatly appreciate it! THanks a lot

What tensioner are you running? The ATI one? Have you contacted Procharger? Seems like that is a relatively popular pulley size and they should keep those in stock.

If Procharger does not have them, send me a PM. I know of a few places where you can probably order one from.

I have a 6 rib kit on my 98 with stock heads, LS6 intake, and TR Blower cam. 3.4" pulley made 5.25#. I am thinking that 8# might be overspinning a P1SC.... When I upgrade to forged bottom end I am going to upgrade to D1SC and rev it up, plus go to 8 rib setup....

My buddy has the 6 rib set-up and a P1SC and he was running around 8lbs of boost. This was on a 2005 Mustang GT. I don't know what size pulley he was running though.

I have a 4.25" pulley and made 11lbs of boost at 6700RPM on a stock cam with my D1SC.
