Clutch Question

[phil_00911]

Just had a quick question....

I have a 2000 Carrera 2 6 speed and 49,000 miles. I purchased the car certified pre-owned. I was told that the clutch has been replaced, but something seems weird. My clutch is pretty smooth and fairly light pressure, however if I get on it above 4K RPM the clutch pressure seems to get lighter for the rest of the time until parked. Then it goes back to being a little stiffer the next time I drive it. Is this normal?

I assume you are saying that you launch your car at 4kRPM+... well, I hope you'll realize your clutch won't last long (and it does not take many launches).

Porsches IMO are not drag strip straight-liners. I routinely launch below 1kRPM.

Sorry.. i should havebeen more clear in my original post. I am not launching at 4K...I realize that is a disaster waiting to happen. What I am more referring to is after clutch engagement and straight line driving. Just running it toward redline in any paticular gear. Example-- take off launch at 1KRPM, accelerator depressed afterward to floor, run to 6.5KRPM, (foot off gas, clutch engage, shift, clutch re-engage) now in second. Now clutch feels softer...

You sure its not you being tensed up when redlining as opposed to having more feedback when you drive steady. Just an observation that i have noted when i am driving steady as opposed to giving it some. Like my gearchanges steady perfect, fast & i struggle with 3rd. Cured myself now by being less tense while giving it some. Probably a load of rubbish but thats how i see it.

good feedback steve.. I am pretty sure this is more clutch pedal pressure than adrenalin.

If this doenst sound familiar I am wondering if I have pressure plate or hydrolic problems

Thanks for clarifying it. Do make sure that you only re-accelerate after fully declutching. I can not make sense of it and I would suggest showing it to your dealer.

I just watched my Porsche mechanic replace my clutch plate and he is meticulous in his work. Anyway, the one thing he did is put grease on the push-rod and its various contact/friction points.

One idea might be that you are getting the clutch area nice and warm as you rev it up... making all those friction points more slippery... and therefore a little softer as long as it is nice and hot in there.
