I've seen a whole lot of videos on the internet with drag race cars getting crossed up to the point of being out of control. It seems they are trying to correct by turning into the skid, but then it whips around the other way, and gyrates back and forth more each time until they lose it. Sometimes the slicks fold under and grab then the car rolls. Sometimes the slicks grab and drive them into the wall. I've seen guys loop it and continue straight down the track, as well as a couple videos where they blip the throttle on and off as they are correcting and somehow that seems to help them save it.
So what are the best driving techniques to try and keep it shiny side up and away from the wall if a guy would find himself in that circumstance?

Short wheelbase cars are generally the worst. The ackerman angle toes the front tires out more and more In a correction as the wheelbase shortens. My dart has no ackerman built into it. Stays dead parallel lock to lock. Recovers very, very well. But it is a be it ch to push around a corner!

When I went to the Frank Hawley Drag racing school, he said "If you get out of the groove lift. If you lift, the pass is over." I think that is very safe advise. But still, I'm curious why some guys blip the throttle.

I agree with the above, out of the gas and as little steering input as possible.
I ran into some crap in the traps a few weeks ago at TNT and was potentially saved by the rev limiter. It spun the tires from 127-135 instantly and all I felt was a little wiggle. This may have been different if it happened somewhere down track where the delta from my RPM to the limiter was greater than just a couple of hundred RPM. It has made me want to get traction control working, I have the sensors in place just haven't set the software side up.

You gotta know when to lift and live for another day.
Its like driving on ice - always use the least amount of steering input as possible.
The more you overdrive the worse things get. Actual seat time is your friend, don't over correct Gentle on the corrections, especially after the first hundred feet I've been sideways more than once past the 330 clocks in someone else's guuk, tranny oil, rear end grease and or motor oil or coolant that the starter didn't see happen until I got sideways in it, NOT GOOD Be safe, live longer

My car is very short.. I only lost control twice.. once when I blew a front tire and I ended up in the other lane and the other time I broke a tie rod end... all I can say is if you loose control,no matter the reason your pass is DONE.. never get back on it.. and your car better be set up right so you dont loose control

The more you overdrive the worse things get. Yep, if people quit imitating the dumb-assary they see on street outlaws of sawing the wheel back and forth and trying to save every bad pass when there opponent is 20 car lengths ahead less wrecks would happen. If thinks aren't going well abort.

I totally agree on lifting at the slightest hint of trouble. If you can feel something at all the run is junk. So i tell myself before every pass to keep this in mind!

Did you design it or modify it for that purpose?

My rule was give it a little correction, if it doesn't respond, lift, it's over and never, ever get back in it.

Interesting replies. My suspicion is the mentioned "overcorrection", might be really be initially a case of a "too slow correction" and over correcting is the second mistake..
Another aspect not yet mentioned, if you want to reduce traction on the rear axle, lifting should do the trick, as all rear weight transfer goes away. With a rear weight biased car, that should increase the pucker factor.
I do agree on the Kenny Rogers thinking.
Please note, I am not a drag racer.
In road racing, keeping your foot in it, which sometimes is the opposite of what you normal survival instincts are, is the right thing, and drive out of the skid.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Mopar Muscle magazine ran a feature on a guy with a Challenger a while back, he raced in one of the "stock appearing" classes. Reading the story, i discovered he'd hit the wall not once, but twice at the strip. Reading the story further, I discovered he had a spool in the rear. I believe a spool can be a factor in many of these wall-banging events. And I agree, assume the run is over, let off the gas and slow down as smoothly as possible.
That was Tom Cannon. If I remember right the first time he scraped the wall his crankshaft threw a chunk of Mallory metal out through the pan. The other one I think he drove over some antifreeze on the track from a previous car that the track workers had not noticed. I found that driving my 750 horse stock appearing F.A.S.T. car on g70 14's with a spool is like dirt tracking. You just steer the right direction, lift a little bit if needed to try and help the tires catch up. The tires are so stiff, and you have so little traction, they're not going to catch and drive you into the wall or fold under and roll you. I think it is a lot safer than slicks.
