from further viewing in the video it looks like he's sorta slipping the clutch cause the car's moving a bit as hes reving it up.

or. was it because he was on a hill. haha

I agree 100 %..... 7k+ clutch drop is way safer than an 4k clutch drop. IMO

rocrfella - Since we're talking about "launching" a car at 6k+ RPMs, we probably aren't talking about daily driving. Please, be responsible, think before you post.

first off: I know theres many threads about launching the s2k. however both have mixed opinions on what is proper technique.

the first technique seems to be dumping/ side stepping the clutch at like 7k or so revs.

people argue that this will cause damage to the drive train.


The second technique seems to be somewhat of a slip of the clutch as to save shock from the drive train.

people argue that this is wrong and will fry your clutch.
__________________________________________________ _________________

now the way I launch (technique taken from launching my subie back then) was to let the clutch out just before it caught. rev. then let the clutch out/catch. keep pedal to the metal. push clutch down/disengage/slip when revs started dropping to prevent bogging.

I did this to prevent drive train shock (AWD back then)


but others swear by the clutch drop method.

which one is the right way to do it? is there a right way at all?

- thanks
Harry, there really is no single "proper" way to launch, and the "mixed opinions on what is proper technique" usually stem from this. If you are not running OEM tires, or if you have an AP2 with a CDV, or if you are on a high or low grip surface, you need to modify the launch, but to minimize driveline shock you want to be sure to always break the tires lose sharply, with a quick impact from the clutch. This breaks the tires stiction with minimal force duration and the cars seem to take it well. XViper and others (myself included) have done thousands of burnouts using this method witout any driveline or clutch failures. HOWEVER, it is important to be able to read the surface and judge the available traction. Even with OEM tires, some surfaces have too much grip for a 6k launch and failing to raise the launch speed is asking for a broken differential.

Anyway, the first rule of hard launches is to be sure that you can afford to replace anything you might break (so be careful).
