looking for realistic expectations; 370 TT
looking for realistic expectations; 370 TT So I'm building a budget 370, wondering what to really expect;
LQ4 Block bored .030 over
Stock Crank
Eagle Rods
Wiseco -11 4.030 pistons
Stock 317s
VTC 3 Cam
ported LS2 intake
Air will be provided via twin TC66 with .58 AR (may need bigger housings, .96? ), A2A IC, JGS WGs and BOV. Fuel will be pump/meth (91 oct and VP M1), e85 would be tooo much trouble. Moser 9, 3.00 gears, TH400, stall is being spec'd by builder.
What should I realistically expect, from my readings 650-700 rwhp seems feasible, is this right?

What kit is it? You might want to go with the bigger exhaust A/R. I know the stock APS kits come with .57 IIRC. Depending on how much boost you want to run that's deff doable. Why is meth such a hastle?
Truck manifold kit, turbos are from Forced Inductions, at the time of purchase they were for a 4.8 
but I can get bigger housings if need be. E85 is tooo scarce in Los Angeles and I like to drive. The only way I can run it is to have two tunes, one for 91 and one e85, and the e85 would only be used for night time activities. & I want run at least 18 lbs

and thanks for the replies, I've combed both of your threads time and time again, nice to have some local folks get to me

I think his TC66 is a t4, not a t3/t4 like the APS you're referring to. So, I would think that a .58a/r t4 turbine housing would still outflow a standard APS t3 turbine housing. Although, I would still go a step higher than .58a/r...like maybe a .68a/r or even .81a/r since he's got an automatic. -Just my .02 cents.

go to the .81 a/r... we ran twin turbonetics 6765's on a t3 exhaust housings on a forged 347 c5 z06, we made 800 rwhp on 18 psi boost pump+ meth..... that was honestly on the ragged edge.... on e85 i feel confident you can make nearly 900rwhp with a safe tune up... of course these are figures though a t56, expect about 5%-10% more drivetrain loss through a unlocked stall th400....
