I have a '99 323IS and am wondering what is the best launch technique from a standing start that won't unduely stress my baby. Where I live there aren't any opportunities for ricer kills, but I'd like to know what everyone recommends so I can practice in case the oppportunity ever comes up. I've raced Formula Fords and have lots of driving experience, but have no idea how to launch a BMW without wasting the clutch etc. TIA

This is the best way I have come up with so far. Clutch in, in 1st, blip the gas twice letting the revs fall a bit in between so that it is around 3k after the second blip then start taking the clutch out and then mash the gas. It's kinda hard to describe, but thats what I use as a launch for auto-x and the like. Doesn't seem to be bad...

Why do you need the first blip?

my guess is it gets the rpms there and spinng so there is some momentum with the rotational mass that way there is less stress on the engine as well when the clutch is let out.

Launching your 3er is like any other, if you have race experience, you undoubtedly know how to launch a car. The kid gave pretty good advice, 2600-3000rpm is a good rev point.

Stress your clutch? I've heard of people driving a 3er like it's stolen and still getting 100K+ miles out of their clutch. They don't call them the ultimate driving machine for nothing.

First blip is pretty much for you to gauge how much you need to do. It just helps me to get a better launch. Of course it is not required, but it just helps me.
