Re: Rear tire air pressure
vic
so if i understand you correctly. your saying that my 60 ft wow's are probally due to spinning tires. ok if i give you that, then where can i verify it on the time slip? i have my wife at the starting line but, i don't think i can explain a "wheel slip" to her and have her look for it. i could i guess give here a cmaera and just play it back nice and slow. but, i don't think she's about that either. to her its fun to be there to watch, not to anaylze the a,b,c,'s of the sport. so, can you see wheel spin anywhere else on the time slip to confirm it. since its to easy to say hum 1.37 instead of 1.31 the wheel s spun, guess i need to drop another half pund out of the tires..... thanks

One of the first thing I would try would be lowering your launch rpm. The car may not 60ft as quick but it may make it more consistant. Depending on what you have for suspension shock settings also make a big difference. Every thing has to work together. When making changes, just make one at a time. On my elcamino I sometimes lower the launch as low as 3200 on a slick track.

Re: Rear tire air pressure
I also have a question I need help on. I have a 68 full bodied camaro with a 509 engine, powerglide trans. I tried radial tires 15X33X15 goodyears, and the car had a violet wobble, the car was all over the track. I was never able to make a full pass on the radial tires. I had to go back to regular slicks to get the car to go down the track. What would cause radials not to work? Also, after several 4 link adjustments by a well known chassis shop, the car still will spin the tires after the initial hit. We can't seem to get rid of the tire spin. I now run the light weight hoosier's 15X32 with down to 8 pounds air pressure. They claim you can run up to 12 pounds, but not in my case. Any suggestions?

Re: Rear tire air pressure
i run the hoosier as well and mine weights 3210 with me in it and i normally run 8.0 lbs in mine their a 14x32x15 hoosier bias ply 1.48 60ft main thing to is get a constant routine on your burnout and prestage routine . normally if you do the same routine evrytime you will get very very close numbers. mine really dont like more that a 3.5 to 5 second burnout ... once in high gear!
