9.60 @ 137 on 13psi
Is this pretty good for only 13psi and running out of gear!? I know I am very impressed with it, just not sure if I am on par with where I need to be. Next time out after licensing we will probably hit it with 16psi or so and see what it does, but I am pretty happy with it for now.
As far as we know it is currently the fastest stock body GTO in the country. And we still have lots of room for improvement! 8.50s are the goal!
3.50 gears soon to be replaced with 3.00 gears
TH400 with 4400 stall getting restalled as well!
We are not sure on raceweight. I want the car to be exactly as it will always be when we go to the track before I weigh it. Still need to add interior pieces and a few final pieces to the cage and whatnot. Probably like 3750-3850lbs... maybe more like 4k with me in it actually.
And the car is running rich still. We want to keep it safe.

The 3.50 gear should take you into the 150s depending on where you are shifting. It sounds like the stall is super loose.
We run the exact same tire, with 3.73 gears, go though the traps about 67-6800 and run 146 out the back.
With 13lbs and twin 42r's you should be getting into the sweet spot for mega hp

Yes these are the 74mm GT42Rs, I bought them from Harlan like 2.5yrs ago.

Either way thanks for the compliments guys. The time money and sweat has finally paid off. I can't say enough about the guys over at Transmission Physicians who built the car for me.


Get it sorted out and you should be flying!
