Heating up the DR's

I didn't know where to post this but it looked cool on film. The majority of this was in second gear. Once they have a weekend test/tune I can get some track footage.

Re: Heating up the DR's

You'll have to learn to stay put in the water box when you get to the track. Heat up the tires quickly in the water box then let off as you finish the burnout. You don't keep your foot in it after you heat the tires up.

Doing burnouts on dry pavement is really hard on the tires. That's why we use a water box. A wet tire is easier to spin and won't chew the rubber off. You need wheel speed to do a proper burnout. I do mine in high gear and estimate I'm roughly at 120+ mph in the water box.

Re: Heating up the DR's

Thanks for the reply. The burnouts that you showed are text book and a lot of people do not know that and are very hard on there motors, transmissions, converter sprags, rear ends, and tires.

My title might have been misleading. I wasn't practicing a burnout, I was screwing around after work. The car only has about 50 street miles on it and a few dyno runs. I'm finally starting to have fun with it.

I've got plenty of track time and usually do a 2-3 shift and let go before it bites. Thats why I immedietly went to seconed in that video because I wanted to be easy on the direct drum and sprag because it's not a hardened one. I also forgot to mention that it was very moist yesterday and the ground was a bit damp from mist. I wouldn't have done that if it was bone dry and hot because it risks choping the tires up and breaking parts.

When I pull thru the water I blip the throttle pull out of the box put it into third gear bring the rpm to 6,000 wait to see the smoke let the line lock off and ease up on the throttle till it hooks.

Re: Heating up the DR's

Second gear does the most damage. Coming out of the burnout, if the tires hit dry pavement and suddenly stop spinning, it will destroy the intermediate sprag. Always be in high gear before letting off the throttle.
