H/c Lt1 Well I made it out to the 1/8th mile track last night. I've been running nitrous the past few weeks and decided to hold off until next season due to my vig 4000 slipping 22% at 6500 rpm. My setup consists off
-Ported LE AFR 190 's
-Bauer Cam( fairly larger hydraulic roller)24x/24x
-Ported Lt4 intake
-38lb injectors
-58mm tb
-tci t400 w/ trasbrake
-vig 4000
-moser rear with 3:73
-prostar skinnies and 15 x 10 on the rear with M/T radials 275/50/15
-Hals all aroud
-BMR and Spohn suspension
The car put down 400rwhp @6600, and 335ftlb at 5600rpm
I'm not so sure how well the M/T radials hook. The best 60' I got last night was 1.70. That was with the fronts on the softest and the rears on the third softest. I had 13.5psi in the rears cold. I don't hink the track prep was the greatest, but I'm kind of dispointed in what it ran. It ended up going a best of 7.7(roughly 11.9 in the 1.4) @ 92.7 mph. My race weight is arounf 3450 with me in it. Any ideas where I can improve or what my problem is? Temp was around 70 degrees with low humindity. I race in Glenwood IA, about 1100 above sea level.

Those tires should work fine on that combo.
My buddy's 95 Formula with QA-1's at the corners and BMR arm and boxed lowers has gone a 1.55 60 foot on the way to a 10.98 at 123 mph on 125 hp of spray on a 383 LT1 with stock ported heads.
The transbrake (if you are using it) might shock the tires too hard to hook up. I'd also try more air. We've had good luck with 16-18 psi.
Good luck!
