Default Most RWHP from P1SC-1?

How much RWHP have you managed to squeeze out of your P1SC-1 on your LS1?

Last time the car was on the dynojet it was at 500 RWHP, and I'm wondering how much more hp can be gotten out of my P1SC-1.

Thanks, Matt.

My numbers are low because my compression ratio is 8.5:1 and I have a relatively small cam for my motor

To get the most RWHP out of the p1sc-1, what is the ideal compression ratio should I be looking at? Also with (hopefully) around 600 RWHP will it be ok to use the stock crank?

Around 9:1 should be the best for maxing out the P1. On a typical build you shouldn't be able to get more than 11-13 psi, which is okay for 9:1.

The stock crank is fine.

If you want to donate your dyno and time I wouldn't mind trying for 650+ on my P1SC. I'm likely going to be switching to a D1SC in the near futrure and I'd love to see what the P1SC will do vs. the D1SC.

We should talk, I was going to contact you soon about a tune and maybe an quick install.

I've done 650rwhp on a mild H/C /forged 346 with a P1. A D1 can push it well over 700rwhp We are currently putting together a mild forged 346 with an F1,looking for 850hp or so
