What else do you have with your P1 set up? I’ve been curious as to what it’s best capabilities are, I’ve got a P1 as well still doing **** to correct the build the previous owner did. What size rib? Blower pulley? That’s a sick time, I’m guess your also a damn good driver?
I hear that! I’m just curious as to what specifically he has done, how much boost? Stock or built bottom end....the details, high 9’s with a P1 is awesome, again I feel it’s safe to assume he’s a hellava driver.
Only makes about 12.5psi, 6 rib 3.4 pulley,stock size crank pulley..it does have a Texas speed built short block with ported ls3 heads but I think it would’ve been fine on the stock bottom end if I wouldn’t of had a mishap with the meth kit on a previous setup
Wow 12.5 PSI! Looks like I’m going to have my bottom end built as well, I have IW 10% OD pulley and 8 rib kit to go back with, replacing 6 rib kit, 3.7” blower pulley and a custom grind blower cam from cam motion. What cam are you running and how much power did 12.5 psi make ?😳
Correct me if I’m wrong OP, but I was under the impression from what I’ve read or been told, 12.5psi on a P1SC1 is a lot of boost? Before my car went down for the rebuild and we tuned it I was making 4.5psi on 6 rib kit with 4.25” blower pulley. I think I’m correct in saying the boost was low or lower because the cam the prior owner had was doing most the work and blowing boost out of the exhaust? I’ll be fine if I make 7-8 psi on the rebuild.

they rate it at like 30 psi max boost I think but that would be on a very restrictive engine obviously..but I am actually overspinning mine so it is completely maxed out

You'll make less boost on an LS7 due to the larger displacement.

That's impressive! Noticed the Iowa plates, do you go to I29 often?
I’m almost 5 hours from there but I was there for the first no prep this year and got runner up in the stick class..I plan on goin to the no prep at the new track in Onawa in a couple weeks
