Thats not really the idea Chris, taking power out of a drag car would be a hanging offence, you simply make it hook up, Top fuel etc and Pro Mods and even cars like SW's and Mine that run say a lenco will all have clutches that are set to slip at a certain rate and for a certain time, that is the only form of traction control but generally not needed until you get over 1000hp. Clutches will be adjusted after each run and work centrifugally.

Traction control in a drag car !!!!!! Go wash out your mouth with soap !!!!!!

Syvecs and Life are currently looking at Drag TC Strategies which are going to be very similar to way it is done on the TT Isle of Man Bikes which Life support for our drag customers.

 

Im sure many of our customers wont want it as some feel it ruins the skill but i know some of the cars i work on that are over 1500bhp per tonne will need it and detecting the slip is fairly easy using wheel speed sensor, long G sensor, weight on wheel sensors but taking away some of the torque safely espically when Nitrous is used is difficult when no DBW units are allowed in Drag racing.

You drag artistes, you've just admitted they are using traction control (clutch slip) but I think what you are really saying is the US drag scene is so old fashioned that electronic control, which would be easier and dare I say it, cheaper, to implement, is taboo :) I am seriously looking at adding multi throttle body DBW TC to my RB26 engine over the winter, as it's such a *ugger in the wet.

Electronics ruined formula 1 why not drag racing as well.

And I thought *I* was a Luddite :) Top drag teams have dedicated clutch man, whose job it is to set up a very costly and fast wearing clutch pack to slip for just the right amount of time, wouldn't it be no less "fair" to do the same by setting up PID with some lap top buttons? Skill is most definitely still involved, cost is reduced, and the crowd would never realize anything had changed. It's only the method of traction control we are discussing, not its use, per se ;)

Fortunatly at the sort of power I will ever have the car that can hook up will always beat the car that has to limit power to stop wheelspin, most of the cars using the slipping clutch are nitromethane and once the throttle is depressed they cannot really get of it and back on without hurting the engine real bad so i don't think they have a lot of use for computers, would the electrics needed even survive that amount of vibration and voltages required by magneto systems anyway ????
