Made a few passes at CFR last night on the 17" nittos Here is my best slip:

60'-2.031
330-5.321
1/8-7.980
MPH-92.57
1000-10.252
1/4-12.155
MPH-118.58

I am excited to get a good tire under the car, anything over about 2500 and it would blow the tires off. I had to roll into it in 1st for it to not spin. The track was pretty good, there was a strong crosswind though. Oh I figured out that I need a bigger tire too, I was on the limiter in 4th right before the traps on every pass. I dont feel comfortable bumping it any higher (currently at 6800) shiftlight on at 6500. Raceweight ~3470 with me in it. F13, boltons, 4.30 gears in a moser 9". Think I should go with a 27 or 28" slick? It will be on a stock 16" wheel.

 

I just ran similar numbers today, I was on 17" nittos with 4.10 gears in the 10 bolt. Trying to find the spot between bogging and spinning is rediculous, can't put stickier tires on it

 

Nice times man. I think im going with a 27" slick, did you run out of gear too?

 

do you think a .5" taller 255 50 16 mt would be enough?

 

It would be close, but I dont really want to be crossing at 6800 anyway.
