I found this interesting PP LS6 heads Speed Inc shop car:
C5R block, 232/232 116LSA cam, 427 cubic inches, TH400 (unlocked) big turbo and LS6 Patriot Performance heads.
900RWHP with an unlocked converter and heavy drivetrain at only 17#'s boost, rolling into the gas as the slicks would ignite on the dyno...
They think 1000RWHP is just around the corner.
Check out this thread...

Very Impressive. I'd be interested to see what valve sizes and prot volumes they used.

Edit: 112 leaded fuel and no a/c or power stearing. HMMM guess i was right on that race gas.

That is a very impressive combo as well.
The point I was trying to make is 900RWHP through an unlocked TH400 at a relatively low 17#s boost and very mild cam is VERY impressive.
I thought it was interesting that they used PP heads and they supported that power level.

Ask Harlan what cam he is running in his 348ci TT setup.

That was the third run on the car and rolling into it and hitting slight electrical problems. Not trying to make excuses but its getting pretty crazy that almost 930 RWHP doesnt seem to be that much.
Anyways, Patriot was the only person to port these heads, however they were told what they were going on and we fulley trusted them. The shortblock in this car is not exactly cheap
Just wait till we crank up the boost and put some slicks on it so it doesnt just sit and spin the tires on the dyno rollers.

The beauty of a turbo is that you can have bad heads, a bad cam, a bad intake manifold, a well designed turbo system, and still make killer power. Instead of racing engines we start racing turbo systems. I'm not exactly opposed to that, because I think that Outlaw 10.5" racing is the most exciting racing that's going on today. There are definaly some closer classes (Comp Elim., Pro Stock, and Pro Stock Bike to name some of them) but it's just amazing what these 'street' type cars are doing, and on a little slick!
