I am debating on going with this setup , how much estimated RWHP can I expect with no stock heads and stock headers?

T71or t76upgrade
forged 346
all bolt-ons and no cats
STOCK HEADS and HEADERS
turbo cam 228/224 .571/.567 115LSA

right now I'm making 525rwhp 545rwtq with no cam, no bolt-ons and cats.

what kind of CR are you at? How much boost are you planning to run?

the compression will be around 9:1 and I want to boost as much as possible. I have boosted 13 psi alot with my t67, I'm not sure how much the t71 and t76 can boost.

You'll have alot more efficiency with something bigger than that 67 that is on there at 13psi, you may even see a jump in numbers at 13#. Have you referred to the compressor maps and requirements on a 346 at X rpm to find out which turbo would be a better choice for you? I would imagine over 600rwhp quite easily with a good tune if you pump up the boost even more (15-16#)

I havent done anything with compressor maps, I thought maybe I would leave the t67 on for a couple months, does the t67 max out at 650rwhp? what about the t71 and t76?

I'm sure someone has done a similiar setup with stock heads and manifolds....ttt

Check the compressor maps on forcedinductions.com or talk to Jose, he'll tell you. You can look them up for each turbo.

I started reading at forecedinductions.com and looked at the 346 air consumption chart and I am still trying to understand everythng im reading, this stuff is seriously amazing. thanks for the link

I havent read up on it yet but how does this turbo cam seem for my setup?
