If you want to make your tires spin, you can do it without burning up the clutch, and you can do it gradually to minimize damage to your drivetrain. Here is what I do.
Rev the engine up slowly to about 4k.
Release the clutch gradually, holding 4k.
When you feel the gears begin to catch, the car inches forward just a bit.
Gas it hard, not hard enough to vtec, and release the clutch the rest of the way. Basically, your gas and clutch should be mirrors of each other your foot on the gas should be as far from the bottom as your foot on the clutch is as far from the top through the whole motion.
Once the clutch is all the way out, floor it.
You should get a good spin, the car will move sideways a bit. It won't make any noise or smoke though. Also, on stock tires it will catch pretty quick so your burnout won't be that long.
The burning smell is burnt clutch. The first few high rev burnouts I tried gave me a bad smell for about a day or two, I was scared I had broken something, and it was the day after I bought it. It will go away eventually. Just remember though, every time you make that smell you just lost 1000 miles off the clutch.
If you want to launch it, without a burnout, drop the clutch at about 3k. The car will not burn out, but will take off pretty quick, its a long trip to vtec from first in any case.
secondly, you said if he wants to start off quickly, to do a 3000rpm drop and go. both that method and the method you described, believe it or not, put much more stress on the drivetrain than a straight 6000rpm clutch dump. it's a shock to the drive train when you "dump" the clutch but then bog down very low. both methods you describe should be avoided. the things that happen to the drivetrain and clutch while doing what you describe are the things that are more likely to damage something.
don't EVER feather the clutch on the S2000 while launching. and NEVER just drop at such a low rpm as to cause you to just bog. these put a great strain and shock on the drive train. if you're going to launch, do it right, with the wheel spin and just straight dump the clutch.

umm hi guys im really newbie at launching with the s2k just got it..... i was use to feathering my GLI and i was wondering what the difference between dumping the clutch, dropping, side step.... guessing the first two are the same and the side step is just moving your foot to the side? to drop it or what sorry for such a noob question but how else can i learn.

I wouldn't do it on a regular basis!
I have never 'launched' the car on a public road. I have learnt to do a pretty good launch from my Auto X participation. Between 5500 and 6000rpm is best for an almost perfect launch IMO.
It's PS2 coordination thing though
I blip the throttle so that the revs hit about 6k and then let 'er go - pretty good most of the time.
Oh wait... you want to spin the tyres right!? Well, I guess that didn't help

My thoughts...
There are two ways of launching an S2000...
The slow way:
--- rev to 3,500 and slip it out gradually (not too long!)
The fast bat-out-of-hell way:
--- Rev to 6500 and drop the clutch as fast as possible. Don't just hold the RPMs up there, but start from idle, floor it, and on its way up, drop it at 6500. Feather the gas while your tires are spinning (about 50-60% throttle) until the tires catch...
The goal is to stay in VTEC... Never drop your clutch lower than 6k, or higher than 7500rpm. Just enough power to break the tires free... which doesn't burn up the clutch, and puts the least strain on your differential.

seems as if everyone has their own way. i learned how to drive stick on this car, so i definitely can't 'clutch dump' or 'sidestep' correctly. but it'd be nice to learn these techniques -correctly-.

first, the method you described is a terrible way to do a burnout or quick start. the clutch is the weak point in the drive train (that's a good thing) and feather here as you've described will result in nothing more than glazed clutch and you'll burn through the clutch quickly. ever hear of the clutch-a-month club?

Most of the time when I have attempted to launch at higher then 6500 rpm, in vtec range, like you describe here the car just bogs out. I feather it out, slightly, I am still dropping the clutch quick though. I just won't launch with vtec engaged.
On a side note, I think its fairly amusing that spellcheck attempts to correct "vtec."

well the only point i'll make is that feathering the clutch is not the way you want to launch the S2000. honda designed this car to make the clutch the weak point (to save the drivetrain from poor drivers, etc. this is a good thing) if you feather it, the clutch is going to slip. and slipping can lead to glazing, and glazing can lead to clutch-a-month club.
IMO you either launch the car correctly with a side step or dump, feathering the gas if you get too much wheelspin.
OR
don't launch at all.
i can't count the posts I've read where people feathered their clutch or didn't dump it fast enough and they glazed the clutch, got the nasty burning smell, etc. and then people wonder why their clutch goes after 30k miles....
