as i sat, watching my daugters soccer game, i started to run through different launch techniques in my head. i'll list a couple of automatics and a couple of manuals.

automatic transmission launch methods:
(in order of least severe to most potential for destruction)

shifter in drive, traction control active, slowly mash gas pedal

shifter in drive, t/c active, quickly mash gas pedal

shifter in drive, t/c deactiveated, quickly mash gas pedal

shifter in drive, t/c deactiveated, press brake, press gas pedal until wheel spin is experience, lift off of gas slightly, hold gas pedal at point just prior to wheelspin, release brake, quickly depress gas pedal.

shifter in neutral, t/c deactive, press gas pedal until 6000 rpm, pull shifter into drive.


manual launch methods:

method 1: depress clutch pedal, shift transmission into first, depress gas pedal until desired rpms, quickly release clutch while simultatiously quickly depressing the gas pedal (both pedals should move, at the very least, at the same speed, clutch pedal can be released faster than the gas pedal is depressed but never slower, slower will only 'slip' the clutch).

method 2: depress clutch pedal, shift transmission into first, heel-and-toe the gas and brake pedal, begin to release the clutch pedal, when you begin to feel the 'friction point' of the clutch engaging slightly depress the clutch pedal, continue to depress both the brake/gas and clutch pedals, slowly workiing the clutch and the brake/gas pedals against each other until you begin to experience wheelspin, at the exact moment wheelspin is felt release both the clutch and brake pedals and depress the gas pedal.



like i said, i was just sitting, watching the soccer game and reviewed a couple of methods i've tried, in various cars, etc.

 

........that will get someone a new tranny .

 

I'm a total noob when it comes to launching. What is the best metod for launching in an A6 C6?

 

i would start with 'turning off traction control'. after that, it pretty much depends upon how your car responds, what type of performance mods. and gains experienced from them, if any, and what you're after, what kind of run, that will dictate the most appropriate sytle of launch.

if you just want a *****-to-the-wall launch, turn everything off, stand on the brake pedal, depress the gas pedal, get a nice burn-out going, start to release the brake pedal, as soon as the car begins to move forward quickly release the brake pedal and fully depress the gas pedal.

if you wanna try to break something, put the trans. in neutral, bring up the rpms (3k+) and yank the shifter into drive.

if you wanna try a nice smooth launch try depressing the brake pedal, depress the gas pedal just a tad (to approx. around 2k), release the brake pedal and similutanteously depress the gas pedal in a consistant manner.

just some methods, others, i'm sure, will have others, hopefully they will share.

 

You will most likely have an accident it you do this. Every ride a bronking bronco for about 20 seconds.

 

It makes very little difference actually. As long as TC is turned off it will run within .03 or so no matter what technique you use to launch.

 

like i said,
just make sure you're in all off mode before you do, though...otherwise all sorts of 'drivers aids' will intervene...

depending upon your tire pressure/traction you will either boil the tires, twist the torque tube, shatter the rearend, destroy the tranny, bust an axle (or both), or have one hell of a ride.

it's more severe on the drivetrain than droping the clutch at 6k.

 

does that impy that even if you 'preload' the suspension you won't best the other guy by more than .03

 

I'll believe 0.3 but not 0.03.

 

So tell me how long have you had this desire to blow up Corvettes

 

not just vettes, every once in awhile you gotta hit'em hard just to see if you really got a car or a pos.

so far so good, but then again, i've got a manual trannny. i gotten aggressive with it and found out about the 'famed' clutch issue.

just don't let me near an 'auto' and tell me to 'thrash' it.

 

i'd love to try, putting it in 'paddle mode', putting the trans. in neutral, bringing up the rpms to 2.5k, squeezing the paddle, ifting into first, and similtaneously flooring the gas pedal.

 

Can't "Paddle" into neutral (and back to 1st). Need the handle for that.

 

can you use the shifter (handle) to place it into neutral then select paddle mode ?

 

Yeah, just put the "handle" back into "S".

 

Hey Zig,

I know there is lotsa well intentioned humor among the flames, but to answer your question seriously:

To launch the A6 on the "street" (hopefully concrete), I suggest "shifting" into "S" with the control systems in "competitive drive mode", assure "1" (first gear) with the paddle - then slide the selector into "D" and then right back into "S", holding the car with the brake, raise the RPM to a fast idle (just enough to make her pull). Lift the brake (do not "slide" the brake) and hit the accelerator leaving the selector ("handle") in "S" - the computer will handle the shifting just fine. I tend to use the "paddles" more in the hills and twisties (winding roads, road courses, etc.) than in a "drag" situation.

For the strip, you will have to experiment with the intended track. Traditionally, strips are slippier than the street.

Hope this helps.

 

This weekend I used the same technique for all launches --- T/C off, brakes on, RPMs at idle, stomp on it. No wheelspin at all, 60 ft times varied from 2.06 to 2.21.

Most first hand accounts I have read say that preloading the convertor does no good at all, better to "flash" it from idle.

 

I use pre loading to effect my RT's. And it does work nicely for that, but as far as ET's launching from idle and pre load have not effect on the ET or the 60 foot as far as I or the timer at the track can tell.

 

Power braking eventually kills the front seal as the converter neck distortes and in rare cases destroys the front pump (I am talking prolonged abuse). Flashing the converter is the preferred way to launch. Unfortunately, every time I run a good sixty 60 my 330 & 1000 ft drop off. So good launch or not "TM" (yup opening that can of worms again gets me ) good launch lousy times...... bad launch lousy times

I checked my time slips. My car does not do this. I have read quite a few posts that indicate this phenomena but it does not show up on my time slips, even when stock.

You know when I launch I don't think I put enough strain on the power braking to break anything. I am really fairly gentle about it. But I do worry about it on the burn out. I am thinking about installing a line lock.
