    No burnout

    I raced last weekend in a 1/8 mile local event which was done on an airstrip. The majority of the cars there, and there was 140 of 'em, were door cars and so, most of the rubber was from the water box to the lights. The track crew really laid on the VHT to keep the traction up. Now, when I rolled through the water box and started my burnout, the tires would spin very little (with no smoke) and the car would just hook up. On launch I was getting very little spin and a couple of times got some very violent tire shake at about 60'. The 1/8 times were good at about 5.20 and 134 MPH. Is there such a thing as too much VHT? Did the lack of rubber at the lights have anything to do with it? Any ideas?

    BTW: I got low ET of the meet - $250 and a radar detector. Red light first round though. I had a bit of a brain fart and let go of the transbrake button a bit early.......Oh, well, I'm sure I'll learn.

    Congrats on the low ET, $250 is not bad for a fun night at the races.


    Tire shake happens when the slicks hook up then spin, then grab then spin, grab etc - they can get very violent.

    I doubt it had anything to do with the VHT never seen toomuch of that stuff be a bad thing if applied correctly, it probably was the combination of a light burn-out and the absence of rubber on the track.

    Usually a quick bleep of the throttle will settle them down enough so they'll go ahead and bite - just make sure you got it pointed straight when you do it.
    BTW, where is this cool airstrip at? I always wanted to run down one of them suckers.

    I don't know where that one is, but the NHRA track in Julesburg Co is an active airstrip. Sometimes they have to stop racing to let planes land.......

    How hot was it ? I've been to several BAD tracks and never had tire shake even with 1.04 60ft's normally it's from lack of burnout, tire pressure or car setup (suspension, tires, converter,launch)

    I had tire shake at Topeka Kansas this year at the O'reily National event. Looking at it on the video the tires spun and hooked three times in first gear. It was so bad it tore my rear u joint out of the drive shaft.
    I would of thought at a National event the track would hook.

    I don't think it would be worth the trip as it's a long ways north of you in Alberta, Canada. They only run the event once a year in June. So I can look for you next year?

    I could not seem to do a decent burnout, as I said earlier. It looks like that may have been the traction problem. I rolled through the water box and punched the throttle to 6800 RPM in second gear and still no burnout. The car just spun a little and then hooked up and shot forward. I was at a good IHRA track 2 days before and the burnouts were perfect.

    try the footbrake burnout next time, roll through water box, stop and hold brake, bring rpms upto 2000-2500 on the footbrake, let off brake and let her rip

    Thanks David, I'll try that next time I'm having trouble with the burnout. Is that how you do it everytime, or just when you're having trouble doing the burnout?
