Hi KLO,

I'm not sue there is much advantage to be had off the line with low profile street radials or trying to heat them with a burn-out either. I would not go too low on air pressure as the tires still need air to safely support the car and not overheat the tire body.But anyway that was what Frank Hawley said about street radials, he said it doesn't matter much for regular streetradials. But I'm no expert on drag racing by any means as my only real experience is a fewtest and tune day 1/4's,1/8 mile fun runs and the twice a year NHRA company drags at Pomona. A couple of years agoFrank Hawley blew up our brand new (as in less than 600 miles on the clock)WS-6 Trans-Am. He was doing some massive smokey burn-outs for the local L.A. TV network promos and I think he spun a bearing because a few days later when the car was cold right after I started it up it seized up solid. When the local Pontiac dealer took the oil pan off to see what happened the whole bottom end was a shrapnel display. What a shame, thatwas an all aluminum motor and is was so pretty. GM had them pull the who drive train and ship it back to them. They took a few weeks to send us a new onefor the dealer to install. It seems that these engineswere beingassembled on a hand line and there was not enough of them to go around and ours had to be put in the queue and wait it's turn.

HTH!

 

Right here is the problem. Get some more seat time. I've been drag racing for 18 years, averaging about 300 to 500passes a year, and it took me about 20 passes to get this car down to where it would really launch well... Don't instantly assume that because your not pulling the numbers that everyone else is, that it's a mechanical fault. Work on your technique and practice! Find the sweet spot and you'll be surprised at how well what you have will work for you!

Also, as for the tires, Low profile is bad. You want the sidewall to have enough room to flex and wrinkle to lessen the shock on the contact patch. Ideal is soft wide sidewall.
