is there anyone out there with a STOCK internals (no heads/cam) running an ATI with over 500hp on a dyno?

if so how much boost?
is it the gwp stage 2?
other mods?

500+ hp on stock internals is what I am hoping for!

yes i think it is possible.

We did a 5lb. P1SC on a 00' WS6 M6 with stock manifolds and cats,with no tuning and it was @ 435 rwhp.

I would have to say with full exhaust,ls6 intake,TB,tuning and a bit more boost you would have it covered no problem.

larry,

I am honored for you to answer my post! I am an avid purchaser from www.ls1speed.com

first I ordered my slp longtubes,last month I ordered a moser 12 bolt, vig 3200, hal front and rears and springs, yesterday I ordered et streets! I must say your the BEST sponsor to buy from. keep up the great work!

sounds like with my mods and going to the gwp stage 2 I should hit 500+ rwhp

That would be nice.. Should take around 10lbs to do it..

It's ALREADY been done with the GWP Stage II kit.
I've seen some guys post those numbers in excess of 500 RWHP.

I'm only 14 HP shy of making 500 HP. But I'm sure I could. I'm acutally not getting my full potential because I'm running super rich at 10.0:1 A/F ratio up to 5500 RPMs. And I don't want to put it there yet, until I get my 12-bolt rearend in.

Also, I am an A4, so with the additional parasitic losses through the A4, I'd STILL be over 500 RWHP even running rich.

Definitely doable! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
