Default Technique for fast take-off

The S2000 has pretty low torque, and even to start off slow you have to get the RPMs above what would be required for a normal car. As for just dropping the clutch, what is the best RPM range to engage at the friction point smoothly? Interested in knowing how other people do it?

If I need to take off quickly ill just rev it to 3k rpms and lift off the clutch, not drop it. As soon as the clutch is fully disengages I just go WOT and it seems work out nicely for me. I hate to drop the clutch and get wheel spin

You could ask this in the racing forum also. But I know that when Im autoxing I usualy rev to about 3500 to 4000 and then let out on the clutch.

The quickest launch is a 6500RPM Clutch dump, and then some throttle control to control the wheelspin. A bit abusive, yes, but as long as your wheels break free you're not doing TOO much harm.

yeah depending on traction, i've found that my best 60' times came with 4000-6000rpm clutch dumps, with slight correction on wheelspin with the gas. and though it may SEEM abusive, it's not really that bad. in stock form most of the wear and tear is going to your spinning tires. your clutch and diff can take plenty of clutch dumps just fine as long as you aren't FI or something.

Change your rear end gears...does wonders for the launch...no more bogging down or slipping the clutch.

To all: Just keep in mind that they were some issues of broken differential once the launch was done from 6000-6500 RPM.

Thats what I have read here.

Define "normal" car. I engage the clutch at 1500 RPMs in my S2000, and I guarantee you that it accelerates with more gusto than my Accord. I'm pretty sure the Accord qualifies as a "normal" car.

I think what you really mean is that your car has less power at 5000 RPMs than your mom's Buick has at 2500RPMs. Sorry to tell you, but that's just a matter of physics. If you're trying to race other cars (or traffic) in the S2000 then 1) don't try beating them in a straight line, and 2) you're going to have to be above 6000 RPMs to produce optimal torque & power.

There's no need to rev the S2000 in order to keep up with "normal" traffic. Now, if you're trying to keep up with Soccer-Mom Jan in her Cayenne Turbo when she's late for her daughter's ballet recital... you may just be SOL.

BTW I have a my2000 and I have done over 200 high rev clutch dumps on R compound tires and I have yet to see any ill effects besides pitting inner CV joints.
What are you characterizing as a high rev clutch dump.
