I've been looking at compressor charts and the turbonetics matrix and was wondering if 2 t-66 .68 p trim turbos would work. I am looking for 1000 flywheel horsepower and I don't want spooling issues at the staring line (have a 4000 stall). The current ls 383 made 550 flywheel horepower n/a.

A 383 is going to be pushing a lot of air. I really don't think you will have trouble spooling those turbos, especially with .68ar. Should push 1000 easily.

What's your compression at?

Its 10.5:1 now. Will have to do something about that. Will probably change the pistons as I like the ehads on it now.

I dont see any problems with 10.5:1 compression. It should easily obtain your goals with twin 6266 precisions. Although, I'd probably go with the .82 housings. Low compression and boost is OK for tuning safety, (its much more forgiving) but I wouldn't be scared of 10.5:1. Be conservative with the tune and use good gas or verified E85-98 etc. The higher HP the car makes NA, the easier it will obtain your goals.

This is just my opinion obviously, I'd like to hear some vendors opinions on this also.

Agreed, you can still run boost at that comp ratio. Hell, ppl boost ls7's and they're at 11:1. Make sure your tune is spot on and meth will help too.
