built 346, P&P ls6 heads with victor jr manifold elbow with 105mm throttle body, cam is still being figured out. 10.5.1, truck manifolds reversed, gt4280 with 1.01 exhaust housing.

wondering what hp i could expect. This is a scrap setup, just something to have fun with for the mean time.

 

Compression is high for much boost on pump gas. Big throttle body is not needed either.

 

I agree on both 9:5 to 9:7 to 1 would be the most I would go to get a safe 15 psi of boost out of her. That should make you close to 750 plus rwhp. The most you need in a T.B. is a ls2 one 230.00 new.

 

Have the pistons cut to lower the comp or sell your heads and get 70cc heads.

 

Is methanol injection an option?

 

Def gonna use race gas, not looking to run on pump gas as im mounting the turbo in the front bumper so being a dd is not gonna be an option. i figured that with the compression being so high, that meth injection plus race gas at least 116 should do just fine. The throttle body i know i dont have to go that big, but its pretty much a hand me down! so why not use it.
