Ton of Boost with stock heads... who does it?
Ton of Boost with stock heads... who does it? how many of you guys are running 25-30PSI with stock heads?
My car is pretty light and i am considering running x275 with a billet 80mm at 2800lbs and was not sure if my motor combo will be able to handle a billet 80 with the gate pinned shut. i suppose it will make around 30psi on kill.

ls9 gasket
ARP 625 aged studs (got em for extra 150 from engine builder!)
LSA Heads 9.7:1 Compression

I think you will find a bunch of people going quick...
And the LSA heads are think are your friend, they are a heavier casting then say a 317...
Boost the **** out of it. Remember... Torque is what lifts heads... besides bad tunes.
I believe Martin was planning to run his LSA heads in RS, and i think them guys pin the gate shut...

^^ lol, same. The lq4 that was in my truck has seen 26psi before and no water pushed. Will be pushing this v3 80mm this week up to 25psi or so...dont think it will do much more than that. I'll let you know if i end up steam cleaning my engine bay, Josh.

what do you mean by it wont do much more? your motor wont handle much more or the turbo will be out of breathe? if your talking about the turbo i highly doubt it.

Verdad Gallardo i really wish i would have went with the AFR 230/245's. i went with the LSA's cause i figured it would have been cheaper but after it was all said and done i spent pretty much the same amount of money! oh well i will make it work!
im sure most guys dont really pin the gate, you get to a point where the turbo will make another psi and not gain any power but create higher IAT's
so you can control the boost all the way till 330". when you make 1300rwhp on a 275/60 Radial you cant put all the power to it right at the hit, it will blow the tires everytime.

got ya, when he said "pinned shut" I took that literally.
I'm running stock 317's now at 20psi on a Garrett GT45R. Going to the dyno again today to turn it up around 25psi or so. Not shooting for a PSI goal though. i'm shooting for an 800whp or more goal.
