2nd gear was my worst wheel spin. Several times it felt like i was burning out in 2nd gear.

I will drop 10spi from my tires and practice shifting at 5500-6200 RPMs and see what my G-Tech says.

maybe practice easing the throttle in 2nd and highly recommend you get a portable air pump. Ideally you probably want to start between 27-32 psi in the rear and nothing higher.

Dynoed the car again this morning at Vivid Racing using the larger 630cc Water/Methanol Injector and made some good power.

402 Horsepower to the Wheels and 368 Ft/Tq to the wheels.

That Translates to 502 Horsepower and 460 Ft/TQ at the crank!!!

Photo of Max is:
Run 1) All Turbo- 387hp & 348ft/tq
Run 2) 430cc Meth- 403hp & 346ft/tq
Run 3) 630cc Meth- 402hp & 368ft/tq

Wow, nice numbers. Hopefully you can back it up with some good 1/4mi times once you get things sorted.

When you try different shift points, just make sure you don't fall out of the boost rpm range.

My problem is tires 265 cant keep 500hp to the ground. I have way to way wheel spin. I need to go to a 295-315 with a Street/Drag Tire.

Don't really care about ET. I really want to see your trap speed. I'm surprised you're only pulling a 106. I was expecting a 115+mph....

This Saturday is open track night at Firebird, I don't have a Helemt or Race Jacket or I would love to run again with lower tire pressure and sooner shifts and see what happens.

Yeah I agree. With a good run, you should be easily at 115+. Evo guys are doing that with around 400hp.

As for helmet and jacket, just go to motorcycle or race shop and just buy one. That should be a drop in the bucket for you.

I think I can put my rear 265's on the front then run new 295-315 in the rear.

factory 10 wide 65mm offset rear?
You're going to have to play with spacers to fit the front as the inside is going to hit your strut. 20-25mm spacers is what you'll need

I could do 265/35/18 on the Front and 315/30/18 on the Rear. Anyone have any experience running a 315/30/18 on a Sport Classic II 18X10 Wheel?

Upgrade your wheels while you're at it. The Sport Classic II's are on the heavy side(relatively speaking), and you will be able to go 11" in the rear pretty easily on the nb. No reason to have 265's on the front since you have a c2 and are mainly doing 1/4mi runs.
