i made like 420 before on a 6 rib with belt slip . I was a p1 with 3.5 ics and just mid headers and cats with 3.5" catback , along with ls6 intake.

I'm now going in for meth , im on 8-9 lbs . I have an sdce 8 rib setup so no slip . What do you think ill get . I also bought the largest air filter brutespeed recommends for the f body and its much larger than the basic filter.

i was hoping and thinking 450-460 . Is that possible adding about 4-5 lbs and meth ? considering i made 420 before , same dyno and tuner btw.

Im also wondering how much someone has gotten out of the p1 ?

So you have a P1 now at what #? I made 500rwhp with a P1 so you have more to go. Do you plan to do anymore mods?

We saw 615 rwhp on an old P1 (straight cut impeller) on a stock LS6 bottom end with a pair of AFR 205s and a Thunder Trak cam at 7 psi. It didn;t have much left, if anything at all

I was at 4-6 psi with belt slip. And made 420. No other plans for now other than more boost and meth along with a retune.
What do you think I'll get ?

Is 500 doable with stock heads and cam if I did a fmic and long tubes

Should be able too. I've seen low 700's out of P1's. Helps having the bigger 8rib pulley setup though.

depends on how aggressive you can get with the tune. id run 100% meth and turn up the pump. if i took a guess, id say close to 500rwhp

I think the tuner likes boost juice which is premixed.
