With a 4.00 pulley I was seeing around 9 psi and running 132 in quarter killing the tires in 1st and second-still running 102 in the eight mile. With a 3.85 I see 10 on really cool day. P1SC-1 isn't even maxed out yet-you can get a 3.10 pulley which will give you 65000rpm at 6600.

Tsab. What is the rest of your combo? I am guessing good ported heads and a nice cam. That is a lot of power for 8.5psi on the stock bottom end. Are you spraying alky?
On 5psi with the restrictor plate in, my car ran 102+ in the 1/8 and 130 in the quarter with a crappy 60ft. But with only 12* of total timing. I want to pull the plate out so bad and let her run. I think the P1 can be plenty fast. But some day I would like to up grade to the D1.
