with the PT76GTQ, a stock set of iron eagle heads, 355 flat tappet hyd. motor, you can lay down 550 at less then 10psi. and since it sounds like its going to be an automatic, i really would not be concerned with spooling that thing up. i mean hell, he could probably even get away with a Master Power T70.

 

i've made 500whp on 5psi on a t67 with an lt1 on a sts kit, non-intercooled. manual trans though.

 

ok? i guarantee it was not through a stalled non lock up automatic which is what this thing will be if they are wanting to make it fast.. sbc and LT1 heads arent the same. stock sbc heads are usually quite crappy in comparison of flow..the example i gave him was a budget build typical setup, saying 550 at less then 10psi was more for a visual that there would be alot of potential for growth later down and the turbo would still be rather efficient.

 

ya its gonna be an auto, but do u think twin would be just as much as the one single as far as the fabrication goes witht the pipes and whatnot

eh, may be a bit harder, you have to merge 2 intake pipes then, and if you run an external gate, you have to buy 2 wastegates, gotta run oil to 2 turbos, it can be done, but it being able to buy cheaper turbo's may quickly be negated between labor and 2x as many other certain parts
