Burnout Lenght?

[Blown03_GT]

I'm just wondering how one determines the correct length of time to do their burnout for? I'm running 26x10.5x15 M/T ET Streets and am having serious traction issues. Just wondering if I'm not heating them up enough or, if possible, over heating them. I've been doing 2nd gear burnouts for about 6-8 seconds.

Thanks for any info.

On nittos I used to do huge burnouts to get them hot, but on my M/T radials I have no idea, haven't been to the track on them yet. I know on my old 16" slicks my burnout lasted for about 3 seconds and I lifted the wheels. Before people comment not in my mustang, what is your tire pressure.

first pass tire pressure was at 14 cold, the final two passes of the night when I cut 1.73 60's I had set it at 11.5 right after I finished the previous pass. I did notice that the wheel has moved about 2-2 1/2 inches inside the tire. Oh they are the M/T DOT slicks not the radials if that makes a differance.

i always cut my 60ft times on my ET Drags whenever i did a shorter burn out.

i know MTDR's like more heat to get them to hook up.

I usually do mine for about 30 or 40 feet.

You really have to just test to find out what works best for your car. Try and test on well prepared tracks first.

Some tires like to be lightly smoked, some like to fog the starting line area.

The general rule is the longer you spin the tires in a burnout, the more you "dry" the tire out. Then the next time you have to spin it more. Basically gets the tire harder and harder.

My dragster I haze the tires( get around 250 runs on a pair of BIG tires). My Datsun I spin them up to 5k in second gear for 3 seconds then release line lock( use them for years, but it is overtired). Tire last longer and work.

BURNOUTS- FOR MOST APPLICATIONS
1. First pass of the day hard burnout. After that follow general guidelines of #2 and #3 stated below.
2. Automatic transmissions and Softer compounds: First pass or two, fairly hard burnout, after that a light burnout should be sufficient.
3. Standard transmission "Stockers": No burnout or short, dry burnout. Super Stock and Comp cars- light burnout, haze tires and stage immediately.

go by temputure of the tire.

colder = harder tire
hotter = greasy soft

try different times to get different temps. when you find the best temp for your car thats how long you spin them. keep track of time and rpm for that temp.

thats why lots of testing pays off big
