[B]I usually launch at about 6k and slip the clutch. I get moderate wheelspin and according to a gtech, i only get 5.79 as a 0-60 time. I'm hoping that I can do better when it gets warmer. I'm also not sure how accurate the meter is.

As i have said before.

The clutch WILL spin more easily at lower RPMs, the reason is that you want to shock the tires into spinning with a high RPM drop, if you don't either your clutch will spin or your engine will stall since the energy has to go somewhere. Thinking that you are doing less damage at lower RPMs is not thinking the right way, it's the opposite.


I suggest NOT to do any clutch drops below 5500 RPM EVER on regualr asphalt, unless traction is bad (ie. rain or gravel...)
How about this for a better way of wording it...

The clutch can get hot enough that it will spin if you try to put the car in gear in normal driving, let alone launches.

If it gets hot enough that it won't do anything but spin at 6000, I firmly believe it is worse to keep trying at that level than lower RPMs. However, sometimes you have to complete your runs, and if it's doing the "I will spin at any RPM" I'm sure as heck NOT going to keep destroying it at 6000! Go launch in So Cal in 95 degree weather on sticky concrete with race tires about 16 times a day, and you'll see!

I agree that low RPM launches in general will cause clutch spin, hence my comment that I launch at 6200 or so. I'm talking about a whole different situation, though...

Sev's technique clearly works, but risks clutch smell if not done right. A good clutch drop should take about 1/4 second. If you screw up and slip the clutch for 2 seconds at 3000 rpm, you probably won't smell clutch, if you slip it for 2 seconds at 7000 rpm, the clutch will probably not grab and you will smell burnt clutch.

I don't know about the rest of you, but I finally have just over 2000 miles on my s2k and am experimenting with launch characteristics. I have found over the past few days that I can get a really strong launch revving to 4500 and slipping the clutch (albeit rapidly). I do have a small wheelspin, but it gets a great lurch forward after a brief pause. No smell and very little wasted rubber. Anyone else tried similar?

I have an idea! How about someone donates their S2K so that the rest of us can learn the proper launching technique. The owner could charge $50 for a maximum of five practice launches per person.

Of course, whoever donates their car would end up with a fried clutch. However, think of the status you would earn among your fellow S2K enthusiasts.

OK, that was a dumb idea.

I have tried this before, and it works (sometimes) But youare doing damage if you end up bogging the car withought wheel spin.
Remember, the worst thing you can do to this car is drop the clutch at below 6k rpm and bog.

oh yeah... with TSB00-054 (abouve), TSB00-55 (1st second grind) and TSB01-100 (slips out of 4th into neutral) you get pretty much a whole new tranny.

TSB00-054 - rumble at 3000 rpms in 1st and 2nd - replace Clutch
TSB00-55 - 1st second grind - replace 1-2 gearset and 1-2 sychro
TSB01-100 - slips out of 4th into neutral - replace 3-4 gearset and 3-4 sychro
