Drag radial tire pressure...recomendations?

It's not going to take much to stick with those times, would personally start at 18 psi and not go over 20psi, do a good burnout and race away.

Heh, with those times you don’t even have to go that far… even 26psi or so with an OK burnout will dead hook off the line with that combination (from experience, I’ve tried it on a simlar, slightly faster car with both 275/50/15 and 275/60/15 BFG DR’s)

I think in my case its the driver not the car. Ihave to be the absolute worst drag driver in the history of man. No consistency, poor reaction times, you name it, I can muck it up. Last night I ran 3 runs. First run stock dual snorkel air cleaner,no D/Rs, and thru full exhaust 15.38 with .271 R/T, 95.07. I am testing stock L69 cleaner vs. 3" open cleaner. No good results yet on which is better. Second Run same conditions except 3" open cleaner,14.68@96.21 mph .168 R/T. Third run 15.10@95.89 .065 R/T with open dump,D/Rs,open air cleaner and huge stumble off the line. I need to learn to drive. Could not make more runs due to COBA and huge turnout. Its hard to get better when you only get 3 runs a month.
