[QUOTE=SmikeEvo]Clutch - eh I like what others have said - pay to play. Just use the 2step method. Do not, I repeat do not try to use a low rpm slip (snakedelong). The more you slip the more you will burn it. The 2step should work fine - it will grap then you will go, not you will slip it and burn it then you will go...

I am not saying do a low rpm slip. I am saying if you rev it up to 7k and just sidestep the clutch then your clutch will not last very long.

Yep, correct with clutch. You will feel it in the pedal.

Your gas pedel will be to the floor - the 2step will be bouncing @ 5k. Let it bounce, you make about 8-10 psi with it.

Ok gotcha - well ya, 7k drop = explosion. This is true for 03/04s. But unless he disconnects the switch, the 2step will engage.

What does it mean when you say BOUNCING @ 5k...the way i undestand it is, hold it @ 5k right?

I disagree, go to a track, and take it slow until you learn the car and how you drive the car. Never go looking to set records on fire the first time out. Thats how you over do it and do something stupid and/or bad.

Try this later in your driveway. Make sure you are fully stopped. Push your clutch in all the way and then slowly push the accel pedal down. It will go up to 5k then stop. If you mash it down (100% WOT) it will bounce - just like it sounds. 2step is also called a "stutter box". In short, your computer (aka 2step programing) will be holding it at 5k, so you dont have to.

Not that you can even do that on a IX since the stock 2-step is 5k, but sidestepping @ 7k won't hurt your clutch. Have fun replacing your grenaded T-Case though.

agreed. The track is the safest place to learn how to launch your car.

Okay, im sure most manual trans. driver have done that before except they were not aware that it was called the 2 step. Now i know.

So you guys are saying that it wont burn my clutch right? or damage internal parts??

Correct, if done right, and not over done - you should be ok. Racing takes its toll though, its part of the game - no way around that.

Just remember its just for fun (no money from sponsors...), dont worry about the car in the other lane, or even what people say to you at the track to get you off pace. Just run your car.

PS- for a stock car, shift at 6800-7k. Over that an you are out of the turbos effective range.

Most (pretty much all) cars don't have built-in 2-steps.

The Evo has two rev limiters. The first, is the traditional "keep my engine from exploding" limiter, which on IX's is set at (I believe) ~7600.

The Evo also has a secondary "stationary" limiter, which is tied to vehicle speed, and clutch pedal position. If speed == 0 and the clutch is depressed, then the rev limit becomes 5000. This is the 2-step that you will be bouncing off for a launch.
