    06 STI Cobb Stage II vs EVO with bolt-ons

    First I have to say that it was not a fair race, because I was by myself and he had 4 people in his car (2 of them women).

    We both were at the light and he rolled down his window and asked if I wanted to race. Of course I said "sure!". I asked him what he had done he said he had bolt-ons, which for an EVO I think can put out about 350 AWHP. I told him what I had and he kind of rolled his eyes.

    Well I held my car at 4k, as I was releasing the clutch I gave it full throttle and all I could smell was clutch... I felt my wheels spin and my clutch slipping (melting) but I immediately pulled 1/2 car on him and was pulling a bit. Just as I was shifting to 3rd a car pulled out in front of him and he let off. I was about 1/2 - 3/4 carlengths ahead at that time. I think if I didn't roast my clutch I would have done better. The dude seemed really cool and he had a sweet looking black EVO.

    I know it wasn't fair but I thought I post for the hell of it. Might as well since my clutch probably looks like a Krispy Kreme donut... If he was by himself I'm not sure what the outcome would be.

    If you smell the clutch, does this mean that it is toast? Or just that is has been over-stressed and will be OK after some cool-down time?

    ^ they say everytime you get that smell that you shorten the life of your clutch, but for all you know you still have thousands upon thousands of miles.

    unless you glaze the hell out of it and heat it up really bad to the point it starts breaking down.

    I could smell it burning for a good 10 minutes, once I let my completely cool down it felt normal again. It's just a unsettling feeling when you smell clutch. I'm dieing to go to the drags but I'm kind of worried about it happening again.

    What's your technique? I saw the threads in the drag forum, I was trying to practice holding it at 4k and quickly slipping but i either bog or smell clutch. Any advice is greatly appreciated!

    Well, the trick is getting the tires to spin. The number of revs it takes to this varies on the type of surface and tires you are running.

    Generally speaking, I find about 5k revs to be the sweet spot. Rev to 5k and then lift your clutch foot quickly. How quickly you ask - well, it was best described to me as about as quickly as you would lift your leg if you had just trodden in dog $hit

    Nice...Good description!

    That's what I'm worried about, my tires are almost bald and I'm going to be picking up some new Michelin Pilot PS2's 245/40/17 and I doubt I will be able to spin those bad boys... Maybe if I put in like 50psi they will spin....

    Ha - those are no bad boys! I'm spinning much stickier rubber with this technique. My car is a Nationally competitive auto-x car with the stickiest street tire rubber money can buy.

    Cool! I've never used PS2's before, but I had regular pilots in the past on my old 04 WRX and I could never spin them. What tires are you using?

    Stickiest Street tire list (in no particular order)...

    Hancook RS2 Z212
    Bridgestone RE070
    Falken Azeni 615
    Yokohama Neova AD07

    I'm running the Yoko's.

    If you don't believe me, go to an auto-x and look at what the top street tire guys are running.
