trouble with burnout
 

Having trouble keeping car stright long enought to get tires good and hot. 2700lb car,little over 600hp 32x14x15 hard compound, 456 gear, line lock, check air constintly, run from 8lb to12lb, same on each side. Could I correct this with frount shock adj. with out interfearing with my launch?? launch is very stright never a prob. would appreciate some good experanced thoughts. dont want to end up in the stands on my launch :shock:
thanks Mack

I've always heard that if a car doesn't go straight on the burnout, You don't have enough wheel speed. Try spinning them a little faster and it should straighten out.

Just a thought, but I used to put my trailer tie downs on my rear axle, they would pull my axel out of line. It would pull one way and then the other. It would launch straight though. A guy came up to me in the pits one night and told me it was dog tracking. I realined the whole car when I got home, and now tie it down by the frame.

mine does that too...goes straight as an arrow down the track but wants to fishtail during the burnout. I get into high gear asap and keep the rpm way up..

Burn out
 

Hi Mack, just a couple thoughts, Did You check the rollout? Maybe 1 a little larger and just showing up while the tire is free wheeling. Maybe preload playing a part, again when the tire is not planted. Dont Gulports burnout area lean anyway, :lol: Good Luck,TC

I get into high gear asap and keep the rpm way up..[/quote]
I've been doing burnouts in high only for years. Just about anything quicker than 12.00 should have enough power. Always get smoke like..right now, and seldom move sideways at all....
I've never understood why most people insist on starting their burnouts in low.

I just didn't know any better. :?

It is a glide with an electric shifter so almost instantly when I mash it the thing shifts into high gear and hits the chip, I then back off just enough to keep it off the rev limiter.

Thanks guys Thanks alot. Is a pg. i shift out pertty quick, have 6000 chip on shif,7200 rev lim. comes on shift light quick and easy, have been shifting just before goes on limiter ,holding brake long as I can ,just befor getting to far sideways let off brake only and launch out. have tried holding longer to see if it will come back but doesn't. seems to allways go same way. Have put new slicks, not broke in good so figure it will get worse. old ones did the same. have been strapping down to rearend and frame in the front, car looks like it is tracking stright from behind but will check it. I never strap it down in park. have raced a few different things for a long time but not much on the dragstrip in last 25 years :shock: trying to learn something . thanks again. soon as I get this thing going down the track like I want I'll take up a spelling corse again :oops: ...
Later Dale
is hard compound hardly any smoke,turning over in water rolling out of water to start

Dale try having your spoter set you out 2 to 3 feet passed the water what I mean is go into the water box and roll out the 2 or 3 feet try that see if it will work. Bring the car out and run with me on pinks all out its coming to our track up here in Oregon on the 4th and 5th of july will put on a nice show.

Burn out
 

Higher RPM will take care of the car going to one side or the other in the box. What RPM are you guys hitting in the box?

I have my burnout limiter set at 6500. I didn't use one with the small block, but the 522 goes right to the 7800 limit if I don't catch it quick....

going to check dia. of each tire. they are new but that doesen't mean much.gona check anyway. going to the track wed.gona put stripe on tire take some pic see what going on at launch.rpms come up quick i shift very quick and nail it, hold it long as i can and let off brake ,but never any smoke. don't see how they are geting hot enought. it does raise front tires most of the time, maybe is enought.
thanks Dale

Re: Burn out
 

keep mine around 6000- 6500

thats what chip we have in right now. we shift at 6000. havent realy timed it , but it must only be 4sec I shift and nail it. still have pedal left so when I shift rpm dosn't drop much if any. never hit rev.lim.7200 am sideways before then and have to turn loose.
thanks a bunch guys
thinking about a trade deal with
bbchevy I know he can straighten
out.

Did I read that right? 4 seconds in low then shift? My entire burnout, from the time I nail the throttle until I'm back at idle is just over 3 sec, high gear only. I'm pretty sure the problem is you're staying in low WAAAY too long. You really need to shift as soon as the tires spin or just burn out in high to get enough tire speed to make smoke, much less stay straight. Keep it short.....JMO

never realy timed are counted to see how long, but feels like that long maybe not. never the less, wed. will try nailing it from the get go, shift soon as comes on light,which will be instantly, just let her eat and see.
