You talking about lauch in as in Maximum acceleration or just around town driving?

Acceleration. I've yet to race anyone in my box, but if a cocky s2k owner started revving at me I may hafta give er a go...

When people risk their lives, shouldn't it be for something very important?
Well, it better be.
But what is so important about driving faster than anyone else?
Lots of people go through life doing things badly. Racing's important to men who do it well.
When you're racing, it's life. Anything that happens before or after is just waiting.

I would do some safe expermentation. It should only take a few gos at this to figure where YOUR car seems happiest!

Good luck and drive safely.

I definately agree. Practice makes perfect. You are going to need to outdrive the s2k owner in order to beat him with a 2.7L and if you have never launched your car before I highly doubt you would win. Go out there and represent! lol

I agree with Adam on the lauch rpms. Ideally, 4.5K lauch but that takes a toll on your clutch as well as possible damage resulting from wheel hop. 3K lauches seem to be perfect for the streets around here. Great hookup (do it right and your head *will* snap back) with no wheel hop...just a nice, snappy acceleration.

Most people can't lauch their cars right so if you perfect this, you'll be able to dust off quite a bit of "higher horsepower" cars. Especially an S2K. Their 0-60 is 5.5 seconds...but that's with a 6-7K clutch dump. Their 5-60mph, as tested by Car and Driver, is something like 7.5 seconds due to their torqueless motor. For comparision, a Boxster S does 0-60 in 5.2 seconds and 5-60 in 5.8 seconds per Car and Driver. Driven properly, an S2K would be close to a Boxster S. But I've put buslengths on them from a dig because their drivers couldn't launch them right.

The first question in the thread was regarding appropriate range to "keep the rpm's at". The answer to this, I would say is between 2k and 3k for cruising. I usually shift around 3500-4000 (extenuating circumstances, such as pesky s2k's notwithstanding )

And I agree that a 4.5k launch is good for racing, but for an in-town launch, the smoothest way to go is to feather the throttle up to about 2k, and then as soon as the revs start to decline, start slipping the clutch, and then when it starts to grab, start giving it gas slowly. You would not believe how seamless of a launch you can get this way with minimal strain on the clutch.

Any tip owners out there who can explain how to do a launch with the automatic transmission in manual mode? I'm new to sports cars in general and completely new to the tiptronic. Bought an '04 S three months ago. BTW, if you can find new '04 models at dealers, you can get a sweet deal, as the dealers are desperate to get rid of the '04s. That is why I got the tip--too good a deal to pass up. But, you do get somewhat of an inferiority complex with the tip, and I sure don't want to add to it by being blown away all the time.
