How Much RWHP/TQ LS7 Supercharged

**rockojugs** · 11-07-2010, 07:48 AM

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.

Just looking for ballpark numbers.

Those are some pretty general specs, but regardless you would be lookingh at some pretty serious power.

Many LS7 cars are producing between 550-600WHP on low boost, so with (fully) forged internals, cam/lts, and a drop in compression to 8.8:1, I'd expect to see anywhere from 600WHP to 800WHP depending on how much boost you're running.

Thanks Wesman. If I can hit 700 rwhp I'll be pretty happy. I forgot to mention the AFR 225 heads. Sorry.

We done prochargers on two LS7 Vettes with just long tubes only.

Both cars made 602 RWHP on 5lbs.

Thanks, Mark. Based on your numbers and considering the additional installs planned & higher boost for my LS7, hitting 700 rwhp sounds realistic. Do you recall the torque numbers on those two cars?
