Well we dyno'd the 05 GTO. Stock long block right to the valve springs. S374 Bullseye turbo @15psi. This was a really conservative dyno too.

735rwhp@5400

745rwtq@4900

This was with 110, and meth injection.

pics and videos tonight.

 

Great#'s. Hopefully you a forged shortblock sitting near by???Congrat's!

 

That's ridiculous... People are pushing stock longblocks farther and farther...

 

Very nice, Duttweiler barely made that on an engine flywheel type dyno with a well built 402 at around the same compression and boost. You're kicking some *** there, congrats TJ.

 

great numbers...just gotta keep it together now...

 

thats awesome.I love it.i made about 630 rwhp with a maggie at 10lbs and a 50 shot.I really like people who push the stock blocks and take a dare.its all in the tune.

 

Damn,
Great numbers I dont think that thing will last long.

Congrats

 

awesome, get the vids up tj

 

Still want a procharger Neil??? J/K. Working on the vid action now. It should trap 140 now hahahaha!

 

we have had a local procharger GTO make 700 rwhp on a street tune (and meth injection). its all in the tune.

they wont live forever liek that though

 

Conserative still at 15 degrees of timing and 11.0 AFR.

Booyah says Bunyan...

 

those are some amazing numbers, congrats TJ

 

Just a couple pics, I will get more, or have dave post them up. On the 565rwhp baseline tune it went 11.7@131, with a 3950#lb race weight. Should go 140 now.

The passenger side manifold is stock with a cross over under the bell housing. driver side manifold is a 6l truck manifold. Waste gate is a JGS 40mm unit From FI. It has 60's, rails, a-1000 and the stock tank is sumped with a return. Clutch is a Ram dual disk. The S374 has the race cover with a t4 1.1 hot side. Comes on super quick and has fairly low IATs at this boost level.

 

WOW thats siiick!

 

Cool stuff! Looks like a very sano install...

Can we take bets on how long it will last lol.

I wonder if you just changed to forged pistons and arp rod bolts how long it would last and how much you could push it, oh yea and some good valvesprings too. I would bet close to 800 and actually lasting a while.

 

That is just badass!

 

thats a mighty effort-

 

Awsome numbers, this is going to inspire me. Pardon the ignorance but the wavyness of the low boost power curve, is that from compressor surge or other random issues? Any chance of a 4" downpipe behind that monster?

 

That has a lot to do with bringing lots of meth in and a AFR that moved around because of that. Also I tried to keep the torque down to save the bottom end. So in the bottom the ignition advance is still in the single digits. There was a lot of room to make more power every where but I decided it would be better to try my best at keeping the bottom end together. With the fuel we were running, 18 degress across the board in boost would have not been a problem. If it had good parts in it that would have been a 900+ graph lol.
