Gents,

Need some advice here. Last night, I tried launching for the first time. I took the car (MY05, 900 miles on odo) to 6000, dropped the clutch, and was off. Lots and lots of wheel spin, finally caught traction, shifted to second at about 7500, and then backed off before going into third.

Got to my destination, smelled that "heat" smell of a clutch. Figured that I didn't launch it correctly (even though I was off the clutch in a split second)...lesson learned.

Got in the car at lunch today, and after the car warmed up, I still smell the "heat" smell. What gives?

have you removed the clutch delay vavle? It's my understanding that with it still installed you're going to get clutch slip during launches and/or hard shifting. When you launched, are you absolutely sure you got wheel spin or was the clutch slipping and you thought the wheels were spinning? I know it's a silly question but if the rpms shot up and you weren't moving off the line fast, you might have thought this lack of acceleration was tire slip instead of clutch slip.

Now to your smell. Obviously you cooked your clutch a little (maybe a lot). If you glazed the clutch then that smell is going to remain for a few (maybe several) days. Baby the car for the next few days and the smell should go away. Hopefully.

Are you sure it was wheelspin rather than slipping clutch? I don't think we get both at the same time.

That's what i was wondering. only i went the long way around in trying to ask this question.

I hate to be the bearer of bad news but you can not do high RPM shifts without clutch slippage in an AP2 until you remove the delay valve.

you probably shouldnt of done that anyway with only 900 miles on the car

the smell should dissipate

chikai

my buddy did the same...

takes a little bit of time (days sometimes) for the smell to go away.

Thanks, gentlemen...it was wheelspin - a lot more than I thought (backend was sliding ever so slightly to the left and right as I moved off the line).

As long as the clutch delay valve is in place, I won't be doing that anymore.

I think the word "cannot" is too strong here. You can certainly redline-shift without clutch slippage if you don't rush to gas it. I can't imagine every AP2 running SCCA stock with R-compounds fries the clutch on every redline-shift.
