Launch Advice For A6

Going to the Drag Strip Sunday to do a pass down the 1/4 mile track. I was wondering what would be the best way to launch and get the best time. Car is a 2SS/RS A6.

In reading some threads, seems like leaving on TC & Stabili-trak could be based on track conditions.

Also was wondering what to expect rpm's to do if just mashing the gas pedal down is the way to go throughout the run. Don't think burnouts are needed. Car has only been modded with Borla Catback Exhaust.

And any other advice. What would be a reasonable time/speed?

Thanks for any help- I'm a drag strip virgin (Ouch!!).

People are saying put it in sport mode (Manual Mode with no peddle shifting), and turn traction control off. I am going to an 1/8th mile strip this weekend and plan to try it once with Sport Mode, Competitive Mode on or TC off.

Would you also just mash the gas pedal? And in Sport mode, will it prevent redlining? Not sure if this mode shifts at predetermined rpm ranges or not. I'll still keep an eye on the tach, but would hate to lift off of the pedal if its not gonna be an issue.

In sport mode with traction control on.
Do not lift gas pedal.
It will shift at or just under redline , No problem of reving to high.

Yeah the only thing sport mode does is allow a couple more hundred RPMs more to be peaked out than being n regular drive.

Good stuff. I tried holding the brake down and running up the rpm's a little before launch but couldn't quite do it- dam prosthetic left leg is a little cumbersome. I'll have to be a 1-foot only driver.

Reaction time is no biggie... just mash and go... definitely don't use the paddles. If you spin the tires turn T/C on and go Competition mode. I ran both ways and times were the same...

Drive around the water box too. No need to throw a bunch of extra rubber up under your rear bumper...

And have fun....

I put mine in manual mode and use no paddles. I push break and hold at 1500rpms and back off break until car almost wants to move and hold it there. Then simply let off brake and floor the gas and let the car shift itself with traction control off. It will put your head back in the seat doing it this way.

I don't beleive this is true, Drive and SPort mode have the same shift points, the only thing sport mode does is keep RPMs higher by keeping a lower gear selected and shortens the shifts to make them cripser. I may be wrong, but I'm pretty sure on this.

I've heard rev to 900rpm max on the line to flash the stall, others feel 1,500rpms is better. What was your best 60' time with 1,500rpms?

I would suggest learning to launch your car with the TC off. You should only use the TC if you're having traction issues (bad track prep) or bad wheel hop. Your car will run faster times with the TC off if you can get the launch figured out.

But if its really cold and there's no track prep, you might need the TC. But if you take it easy on the launch, roll quickly into the gas instead of flooring it, you should be able to get off the line pretty cleanly with the TC off.
