I'll be over 600 rwhp in late January. I was at 500 rwhp last time I dyno'd and I've dropped a couple of pulleys sizes since then. I am waiting until I can put in a higher capacity fuel pump and then I am going to flip my cogs on the back of the maggie to overdriven and see what she puts down. I just had Daniel's rebuilt Century transmission and gforce axles installed, so all that's left is the fuel pump.

I'm not really worried about modding a possible "collector's item". I can always put it back stock

Oh, BTW, I do know for a fact there is one other Texas GXP on this board pushing well over 600 rwhp. I don't know if he wants to be named though.

To all the guys running turbos or superchargers, is everyone on a stock bottom end? Any head work? Interested in cam specs if they aren't proprietary. Thanks!

Yes stock bottom end.

No head work.

TSP 231/236 .641/.613 112 LSA

Didn't have turbos in mind when I bought the cam, so it's not exactly a "blower cam" but it seems to be ok. If I would have planned on doing a power adder, I would have gotten something different.

I had my fun with it. Ready for something different. Decided to sell before I blew it to bits!

Your car is badass, but this thread is about about GXPs pushing 600+.

Interesting... drag radials I assume to get proper load on the engine? When I was under 600 it would still destroy street tires, over 600 was silly and made it hard to log anywhere but the track. You ever take yours down the track? Be nice to see a turbo car finally make a pass.

Weird when my car made enough power to go 134 in the 1/4 with the slicks 2nd gear got traction most the time. When tuning/logging ty' car it fights for traction anything below 60 (10psi) on the 295 street tires but is manageable.

Not sure which gears you had? I had 3.70's like the M6 GXP's which doesnt help traction any. I could see it being much better with 2.92, 3.27's, etc.

So all the fast G8s are gray GTs? Well, at least I have the right color.

I have 295 Hankook street tires. It's pretty manageable @ 8.5lbs where it's at now in 3rd and 4th, I haven't driven it on 10lbs yet though.

I hope to take it down the track next season.
