Forgive me if this is a noobish question, but I havent got the heart to test it out myself since my S2K is my only car.

Somewhere around here I read that you can get a pretty good launch from 6-7k rpms and dump the clutch.
I told some of my co-workers and they laughed saying that something would break if I tried to launch in that high of RPMs.
So my question is, has anyone launched a stock s2k that fast? if so did you encounter any problems or excessive wear on any components.

they wanted me to try it, but i couldnt risk breaking anything, so im asking you guys first
I have a stock s2k with aftermarket suspension.
thanks guys.

 

Well, if you launch above 6K, you would probably get a clutch burnout.

Nothing serious, i've done it a couple of times, so I talk from the experience. The only consequence is a nasty smell that can last for hours, and the car wont move.

Even that, my first clutch lasted 90K Km. (56K miles) and I did it a couple of times, so if it happen to you ONE TIME don't worry. (But don't do it any more!)



The proper way of launch the S2K is to drop the clutch at around 6000 and let the RPM build until red line in each gear.

 

The S2000 wasn't designed to be launched. This is evident by the number of differential failures. If you are planning on launching you want to break the traction of the rear tires. The wheel spin will put less strain on your drivetrain and you'll have less of a chance of breaking something.

Yep. In fact, this clutch burn is a great protection system for the differential!

 

I launch my car like that quite frequently. It's easier on the car when you are on the street versus the track because the rear tires break free much easier. On the street 6k is enough to break em free with a side step. On a properly prepped track it usually takes 7k+ to get the rear tires to break free easily.

 

As stated above, you can launch the car above 6k and get the tires to break loose. If you get off the clutch fast enough, you will get minimal clutch slip. If you get off the clutch too slow, then yes, the clutch will slip and you will get the bad clutch smell.

Also like stated above, on the street, launching the car at 6k should be fine. Unless you have super sticky tires then you might need a bit more RPM. If you break the tires loose too much, modulate the throttle a bit until you get traction and then back to WOT. If you launch below 6k, you run the risk of sending all that stress to the diff since the tires aren't spinning. This is when things break.

Your friends don't know jack. Do they realize you have a 9k redline? Launching our car at 6k is like launching a mustang at like 3-4k (guesstimate). However, cars that are made for straight line performance usually have stronger diffs...

 

There is some dangerous advice in this thread.

/waits for the "WTB: AP1 differential" thread.

 

The trick is getting off the clutch instantly. Do not ride it up with your leg. And you do want somewhere north of 4K RPM at the time, depending on road surface. Extra RPM will not cause clutch slip, just more wheel spin.

 

Dangerous advise would be to dump the clutch at 4k on a drag strip. Advising the OP that a 6k side step is better is hardly dangerous.

 

I'd advise against doing burnouts in the first place. The diff AND the stock clutch are pretty weak. I (and others) are simply stating the safest way to launch the car that would reduce the risk of grenading the diff.

A 4k clutch dump is getting far too close to the "danger zone". Stick with the 6k dump. Sure you'll probably get some wheel spin but that's better then blowing up the diff. You can control the spin with the throttle quickly enough.
