Been a best of 1.38 with a set of worn out tires, and unprepped track. That was with the 317 headed 370, Pt88, off the foot brake. Had to abort run due to frame twisting and sticking the truck in 2nd gear. Best 60' with the stock 245/17's is 1.61 and that was at irwindale a few weeks ago.

have you done anything to your suspension to help traction? i had trouble with mine spinning the other night and could only get a best of 1.65 60's. i would like to get it into the 1.5 range. i know our trucks are very different but figure the idea behind getting a 4x4 to grip would be the same either way.

I should be pretty close to you next weekend on 93 octane and 13.5 psi trapped 99 with 14-16* of timing and 6100 shift points since then we adjusted shift points, 20*'s up top and made timing ramp much more aggressive for spoiling issues!

I hope I can get some numbers close to yours or maybe better lol nothing wrong with being a dreamer!

I had spring clamps and a hoaky traction device I made out of the over load spring when it ran 9's but took all that off a few months ago it was creaking and annoying me. 2d vs 4wd is completely different. With 2wd you want weight transfer and the rear to lift, as well as lift the front. 4wd you don't want weight transfer, you want to keep all 4 tires on the ground. After high 1.4's this becomes a challenge with a 4wd. A properly set up 2wd is the way to go if you're running on a good track.

Cool I need an excuse to buy some slicks, and test out the GT76 lol
Went a little quicker on the lil street tires, and 91 0ctane last week but I forgot to post...

I'm sure you got some 9's in the bag, any reason you wont go to 16-18psi?? I wish I was on a T-4 flange I regret T-6

With the TC76 it ran best at 15~16 psi but this T78 with the same little 68mm exh wheel chokes after 13~14psi. I tried 16 psi on a 1/8 mi run and lost almost 2mph on the 1/8 and was trying to detonate. The t78 compressor must move the same air at 13 psi as the tc76 at 15... Exhaust is constipated.
I'm pretty confident it will go 9's with slicks, and the GT76 on 16~18 psi if I don't run over the crank lol Truck is my only dd right now so I don't want to push it any harder but It should go easy 10.20's on 14psi with slicks, and the T78. I ported the heads a couple weeks ago and picked up some good mph...

The T6 flange should be ok just need to have it set up to make good tq NA to get it going. It should net you some good mph.

The nitrous I'm adding should net some good torque , also thinking of switching to 1.10 AR we will see how my next pass works out.

Ps. You need to get some more videos of your truck!
