I am getting more and more tempted to try to launch my car at 6 or 7K, but my old habits come from my first manual car which was a 1990 Taurus SHO. There was an issue with those where if you launched above 4500 or 5000 then you would risk shearing some pins off somewhere in the tranny.

Also, I'm not a fan of doing this on the streets. Plus my car is still plated by another province as is my drivers license. Cops are cowboys out here and I already had my Ontario, Canada license confiscated last week while hailing a cab. Apparently they don't like if you step off the curb to see down the road, and their computer shows my driver's license as stolen.

For now, I'm flyin under the radar...

Oh I voiced my opinion about the treatment they gave, including all of the threats of multiple tickets and arrest. Of course they just let me go because they're so nice... when I asked for either of their badge numbers or names so I could retrieve my license more easily, they responded "they'll know us." I'm sure my cab-hailing action warranted them driving the wrong way down a one way street. Anyway, enough thread jacking by me

I don't think you can measure the clutch wear accurately without dropping the transmission. I suspect they'll say that the clutch is OK as long as it is not slipping excessively.
That's the uncertainty that bothers me. I'll just keep wondering if I'm doing damage. Frankly, I'm not ready to pay so I'll just play nice. Soft starts followed by hard acceleration is better for me.

make sure you have crappy worn out tires with no grip when you're doing burnouts. It makes more smoke, and it wont screw your diff too bad.

mx5, yeh, I have hard time "side stepping" the clutch. It's just too much. I've tried it few times, and it is fairely harsh on the differential.

You may not believe me, but it is proven that it's safer if the tires do spin a lot to unload the load on the transmission. I've seen an Evo with 330whp do a AWD spin launching by dropping the clutch at 7k RPM. Now, if you don't commit completely, you're gonna blow your transmission and transfer case and the front differential,(i've seen it before).

Your stock clutch is designed (probably) to break before your transmission and diff. but if you've taken your clutch delay and have an aftermarket clutch, it's likely that over a short period, hard launching will effect your differential and transmission.

Like I said, if you want to play, you have to pay.

I've done the 7k drop with an R-32 GTR running S03's, and it does take a bit of committment.

AP2's have the CDV to "pad" the clutch action a little, but my stock AP1 clutch doesn't slip much at all when breaking the rear tires lose. We've seen several people spit the gears out the back of the differential using the stock clutch, but we've also seen people fry the stock clutch without busting the differential. In the case of the S2000, it appears that it can go either way.

That is in part why these threads make me uncomfortable. You can screw up the car two different ways trying to smoke the tires; You can either fry the clutch or bust the differential if you make too many mistakes. It's not right to tell people that the car can't take it, because we know from the experience of more than a few people that it can take MANY MANY hard launches without the first problem, but at the same time, it's apparently not that hard to break or fry things, because we've seen lots of people break and or fry things trying to light their tires.

I generally only light my tires or do donuts just before replacing the tires. I tend to run my tires too long (until the tread is well and thoroughly unsafe on wet roads), so when you see the videos of me doing burnouts or donuts I'm usually on tires that are not delivering anything near optimal grip. I *rarely* light up a perfectly good set of tires unless I'm playing DK on the autocross course. However, I don't hesitate to light the tires regardless of their condition if the situation and opportunity come together with the right mood. Sometimes (though not very often) I do insane burnouts when launching for an autocross run. It doesn't help my times, and often hurts them, but the spectators love it.

I have mixed feelings about this stuff. You can break the car, so should we advise people not to do such things? If you shift quickly at redline, you can miss a gear and trash the engine, so should we advise people not to rev to redline and not to shift quickly? The whole point of this kind of car is having fun, and we just have to limit our fun to the things we can afford. If you can't afford a new diff, clutch, and tires, don't be hammering the driveline. If the cost of fixing the damage doesn't matter, and you want to put slicks on your S2000 and hammer the driveline to see what happens, that's OK too, because it's your car and your choice. Just don't write checks you can't cash.

It's also fun to feel the car pull through first and then hit VTEC.

One of the cool things about the S2000 is that it can be enjoyed in so many different ways.

did the 6k drop today.

car caught well. didnt feel like i was hurting the car at all.

tires spun but i sorta messed up cause i eased off the gas to much and the revs once the tires caught (smoothly) went down to like 4.
