Default Turbo LS1 dyno estimate...

Figured i would get a feeler for what to expect..

2000 Trans am, 6 speed, 9 inch

forged 370 CID
stock 317 heads (dual springs etc)
speed inc tu2 cam
LS6 intake/ ported TB

Dual pumps with -8 feed/ -6 return and 80lb injectors

Precision PT76GTS turbo

My waste gate spring is 11 psi, i plan on turning it up to 15-17 psi

mid 600s-700 wheel. Depends on timing/air. What does a PT76GTS run out of steam at? Is that billet wheel?

we did my buddies 370, "boost cam", stock headed, s475 a2w setup a couple months ago. Made 710RWHP on 13psi. This is through a locked 4l80 and dana60 rear with 3.73 gear. It will make 709-710 pull after pull.

I think the s475 with cast wheel is close to running out of steam on us though

Im going to say 695 HP. The 9 inch will eat up some power.

My 4.8 makes 650 on 17psi through an 80e lol. A 370 ought to see 800s with that turbo at 17psi, otherwise your tuner is doing something wrong. That's assuming you have good fuel...
