60 ft. Time Questions?
You main problem is your tire pressure. You need to try 16-18 psi. Many people make the mistake of too low pressure, and what that does is make the tire compress more, which you do NOT want. The tire is a spring, when it overcompresses, it's like a spring at full squish, and the only thing it can do from there is release. When that happens, the rear end bounces back up, and the tires unload.
Follow these simple guidelines (for full or DOT slicks, not for drag radials):
1- run 16-18 psi, and check your tire pressure before EVERY pass. Your pressure will rise 2-3 psi after your first burnout of the day, and the sun on one tire will make your pressures uneven.
2- make sure there is water down, wet both wheels, pull forward PAST the water, then do your burnout. You do NOT want to do your burnout IN the water box. Try to drive around the water and back the rear wheels into it, if the track allows. This way you don't track water up with you via the front wheels.
3- do your burnout it drive. many people make the mistake of using a low gear. You want wheel speed, NOT engine rpms. Let it upshift all the way into 3rd, you'll probably be doing close to 90mph on your speedo. When you see tire smoke, let it spin for about 3-5 seconds more, then roll out with it.
4- DO NOT DO A DRY HOP! Your best traction after the burnout is your first use of the tire. A dry hop (i.e. a quick "test" jab) takes heat out of the tire and uses your best chance for traction.
5- launch the truck between 1000-1100 if you have a stock converter. Not all trucks work best at the same rpms, but MOST trucks like this launch rpm with the stock converter.
Take a second and watch this from behind video of my 10.48 pass. It shows my exact burnout procedure. Notice I pull the rear tires over the water, do a quick spin while in the water to wet the tire, pull forward and do the burnout. You'll also notice how low of rpms my motor is at, like I said, WHEEL speed is what's important, not engine rpm. BTW, I pull right through the water with my front wheels because I run a skinny race slick on the front.

Thanks again for the info.

Thank you guys for some priceless info. I have been trying to get it right for 2 years now. Must of the guy's at the track are ethier too fast or to busy to help!
Looks like this season is gone but I will try some more if weather permits. I have never been able to get that much smoke out of it. I have felt it switch gears during my burn out though. It get a little discouraging to see guys getting better times? I have gotten a 13. 249 @ 105 mph. with a 1.9 - 60 ft time. and .506 reaction. My truck feels strong though I have never had it dynoed yet? I'm looking to put a pulley on it and a chiller box as well as some traction bars.
Peace, Suavy
