Dynoing tonight, any estimates for combo...LSx/S95 Here is what we're strapping down.
438Cid LSx
ET LS7 heads
GMPP Carb Manifold
105mm TB
Chiseled 3000hp IC A2W
S95 turbo
Stef's Dry sump
160# injectors
Solid Roller(260/254) ~.700 lift
Jesel J2k Rockers
Glide
3.50 rear
8.5:1
Tonight we aren't going to hit it hard, maybe 10-15psi. Looking to get the car to run strong at those numbers, will work on fuel and timing to get a big number under the curve. Inital plan is to make pulls to 8k or so and see how the turbo likes it. Any guesses?

Ok just for giggles....
Lets assume 7K RPM's, 15psi, your intercooler will have about 2psi drop or so, and outlet temps should be about 80-90 degs at the end of the run, though this is hard to assume since it will depend on how much ice water is flowing through per minute.
Your back pressure should be about 1.47-1.42:1, assuming EGT's stay around 1500-1550 or so.
comp efficiency on that unit should be around 72% judging by the #'s. That means the motor should make around 1205 crank HP. Hard to say what % to take out for stall and auto, but that would put you around 964rwhp assuming 20%.
