Any guess on much rwhp/tq with LS7 (forged internals) ATI supercharged engine (93 octane) one should expect to see. Long tube headers, cam built for supercharger, fuel system upgrade, and 8.8:1 compression on 8 to 10 pounds of boost.

Just looking for ballpark numbers.

Thats a little low for compression on a S/C motor. What blower is it? Cam specs? We need more on the combo then that.

I initially thought it would be 9.5:1, but Pro Line Race Engines is recommending 8.8:1 based on heads and cam.

ATI Procharger D-1SC 8 to 10 pounds of boost

If your only going to be seeing 8-10 lbs of boost you should raise your static compression to 10.1-10.5 I don't understand why you need to lower the compression based on the heads and cam

Dont understand why compression needs to be that low either but you should see 700+ rwhp with that setup good luck.

9.5-1 is perfect. Dont go lower. Blower cars get a little doggy out of boost with low compression. 700 should be pretty easy on 10psi. I would try to upgrade the blower to a F-Series though. You'll tap a D1 out pretty quick on that combo.

What trans and rear??

I agree with blue00zzleeper low comp and low boost with blower is not a good setup...

630-670rwhp is my guess and low mid 500rwtq ..

at least 9.5 on that motor i did 15 psi on a 11.1 ls 427 with pump gas93 and meth

Keep the compression Low and change the head unit out to a F1C and turn up the boost to like 21 or 22 pounds and you will make some killer numbers on pump gas , I would say 825 to 900 range. You will like it, my little 6.0 with an F1A Made 775 on 18psi , I need to dyno it again on 21 pounds..

Unreal

Stock ls7s are making 650rwhp on 7-8psi.
