Ran a new best at Darlington last night. Finally got my 8 sec pass! Went out there to do a little testing for an upcoming street car shootout. I had taken the 275 pro radials off a couple weeks ago and put a new set of 295-65 radials back on it...same size I used to run. Never liked the looks of the 275s on my car, never ran any better on them than it did w/ the 295s, and I couldn't run the 1/4 on the shorter tires. Track was hooking great for everyone but me to begin with. First pass it just lit the tires up, so I came back and made some adjustments on the shocks and left the new 295-65 M/T drag radials at 18.5 psi. The next pass it pulled the front wheels about 1 foot up in the air and then the nitrous came in...gained another foot or so of air under the front tires and carried it for about 100'. Got a little squirrelly when it came down, but I stayed in it b/c I knew it was on a good run. 60'...1.311 1/8...5.710 at 121.57 mph 1/4...8.955 at 149.70 mph Not sure what tripped the 60' beam, but it wasn't the front tires. That was just my 2nd pass, but it was late and I was happy  , so we loaded up and came home. I have just now gotten a handle on the traction and haven't even started tuning on the nitrous yet. I think there's some 8.80s in it easily. Want to thank Stephen Daurity and Monte Smith for the advice.  Not bad for a 3900# street driven car.

Thanks yall!
Mr. P...not sure on the weight percentage. I have it in a file at home from when I scaled the car years ago. I'll look and see and get back to you. I ran 18.5 psi kind of as a baseline last night. The fastest I've been on motor was w/ 20.5 psi in these tires. Just wanted to be sure it would hook last night, that's why I ran them lower.
Spraying about 250 hp.
Thump...thanks and yes, the car runs 9.50s-9.60s at 140 mph on just the motor.
