Default made 508 rwhp through a th400, what kind of ET do you think I can run?

Car is a full weight street car (probably 3800 with me in it), rossler th400, trans brake, 9" with 3.5 gears, 17x10 MT ET Streets, t76 turbo, 10 psi, 91 octane, 370 iron block motor with 8.7:1 comp, stock 317 heads with comp 921 springs, 02 z06 cam, vigilante stall, hard to say exactly what it is, was supposed to be a 3000, feels like a 3800 or so. It's too loose, i'm having it tightened up a lot. finally gets into hydraulic lock around 5500 rpms at 10 psi. Stalls to 4000 rpms on 5psi with the boost clibming pretty quick and the stall speed rising.

Just wondering what you guys think the car can run. I believe the uncorrected dyno numbers were around 460 rwhp.

Somewhere in the high 10's would be my guess, depending on your 60' time. Gotta be somewhere in the 125-130mph trap speed, due to the weight issue.

I'd say mid to high 10s depending on traction and air quality.

Guy with a 402 on motor that made 515 rwhp just ran 10.92 @ 124 last night... with a lazy 3000 rpm launch, car's got a th400, etc.etc.... so you're probably in that high 10 range with that power. Weight and traction are gonna play a bigger role then the power... you are making enough to run 10's, just how far into the 10's or how far away from them you are are dependant on the above 2 factors.
