Advice on best way to launch from dead stop? - Benzworld.org

I want to know the best way to launch from a dead stop to get the best quarter mile time.
Manual shift with Traction control off to me does not seem as efficient as just leaving it in D with traction control ON and just nailing it letting the car leave with the traction light blinking a bit and let it shift to the next gear on its own.
I know the D method with T/C on is not as dramatic as the manual and T/C off but I'm looking for most efficient.
Please advise.

I feel that with the traction control on and just mashing the pedal from a dead stop the car has aweful pickup, due to the traction control kicking in, and limiting rear tire spin.

I find that with traction control off and in D, it will spin briefly when the pedal is mashed to the floor, but then it will launch. Or, with traction control off, doing a controlled launch to about 3000 rmp, then mash the pedal all the way to the floor.

thanks kev I was thinking that with the T/C off and leaving it in D that it might shift into second early from the RPM's associated with hard tire spin from a dead stop.

I haven't found mine shifting early. You will definitely get some tire spin though. But as I have learned in the short time I have had mine.....most of the cars I meet up with spin the tires as much or more, anyway.

Traction control off and floor it in D. All other methods are not as quick.

ESP must be off to get max power. If you have traction problems like me, [:D] roll into the throttle, but leave ESP off for the fastest runs. I haven't seen any advantage in manually shifting it.

What if my traction is much worse than yours? Then what? LOL[:D][:o)]

ESP off it is... and I agree that manually shifting is no advantage and in fact if you don't time it perfect you can bump off the rev limiter going manual.
I wish I had the air packin option so I could feather out of the hole like f55 but I'll have to tough it out with my stocker.

James, if you have worse traction problems than me, you're parked without slicks!![:D]

So Brad what do you suggest? Grey poupon perhaps or a set of hoosiers? lol[:D][:D]
