girdled 109 .040 over diamond forged pistons, eagle stock stroke crank, forged stock stroke rods
decked .020, steel shims, single (9:1 ish comp)
BHJ balancer internal balanced rotating assy
218/218 roller, stock ratio chevy style Scorpion roller rockers on ported GN1's
intake ported to heads, 70mm plenum, 70mm Tb, T70 P Trim, 83# inj, ATR headers, PTE FMIC, all RJC pullies
3400 9/11 2004R

I know but Im just curious :biggrin:
 
700-800hp and similar torque, depending on the boost levels. Over 140mph in the quarter at 3600lbs if the tune is right. Let us know how the .040 over bore works with the high HP. Dont detonate or you could crack the cylinder walls.
 
I was looking at running in the 30-32 PSI range, that is the reason I decided to get rid of the stock crank and rods since I was limited in what I could run boost wise before worrying about them twisting. I have the cars weight down around 3400 now. Its on a diet and more is coming off. Trying to get near 34-3500 race weight.
 
Your going to fly. I have a similar build up minus the heads at this point. I got my friends car in the 10's at 127+ with iron heads, 67p turbo 26psi, 210-205 flat lifters, MSD 50's and a lot of alky. Through a stock MAF with one screen removed and stock ecm. And this car weighs 3700+ with driver. You should be able lay down a lot more mph with more mods and a lighter car.
 
I'd tell you the torque and H.P. will be lower due to the size of the turbo. Probably 700 H.P. or just over if everything is right. Also the car won't run 140 MPH either. 135 MPH would be on the high end more likely in the 132 to 135 MPH range.

Well you know what my car ran with those heads and a slipping trans, and you have more cam and less weight. BUT I was running a Q-trim 72.

Hope you have better luck with the 2004R(x2) than I did. :frown:

Think you're going to need a Q-trim for high 13x mph.

Looks a lot like Jason Cramer's Combination with the exception of the turbo.
I would say go a little bit bigger on the turbo and you could do it.
Jason runs the GT-70 Q trim 3 bolt turbocharger, Precision 85 exhaust housing.

His has run in the 9.8s at 136 Plus

Im going to upgrade the turbo at a later date, prolly a 72 Q trim or so.
 
67 with 69 trim wheel, 221 hyd non-roller, 75 lb inj, ported iron heads, ported intake, FAST, 3 inch DP, stock headers, 3850 race weight with driver at 26-27 PSI boost, 93 with alky. Stock crank, stock rods, stock GM OEM pistons. Good rod bolts, good rings, girdle.

Turbo is rated at 700.. 132 is 700 to the wheels based on weight vs MPH.. somethings off :biggrin:

Sometimes you can get more than things are rated if your careful on your tuneup.. use what you have, then make changes.
