Third post - Clutch talk for reference

Hi all,

You all have been great as I posted a couple of times about my engine and clutch issues. I now have a new engine and clutch thanks to porsche but now I find myself over thinking my clutch work and am still not convinced the clutch is fine. Any thoughts would be awesome. I never believed I burned out the clutch at 2500 miles, but I think can always get better and if there is something I should look at I want to (before I burn another). Basically the whole experience has made me doubt myself and the car. I really just want to get back to driving and having fin.

Clutch control . -
1. I mostly give enough gas to get it to 1k rpm prior to pulling out the clutch, or at least during the first 10% release. Everything is OK, but anything other than a feather pull results in a jerky release. By featerh pull I mean easing into the clutch "power zone" where it passes the power to the transmission and engine. This I would think could lead to wear over time. My car can pull out with clutch only and go 5mph.

2. I match engine to RMP's on downshifts, but I dint always bother if I am coming to a stop. I just neutral and come out of third or second. On up shifts I still try and match since a hard pull of over 4 k RPM's will not have the next gear at less than 2k so you need some pre-rpm's to match the engine to the now lower rpm amount.

3. I find my clutch heavy in the release and cant seem to get a fast pull out to work well. This car should be made to do it.

Questions:

1. I was told to just let go almost on the release on the clutch instead of feather it out. The dealer told me this would save wear on the clutch. I drove other 911's and this is easy, but on mine the rebound seems to swift to match correctly without getting any bucking. The faster I try and pull away the worse it gets. Is there a way to test and or change my release pressure?

2. New clutch but I am still getting clutch smell every drive? It may be the new one (200 miles on it so far), but this does not seem normal going around town just driving normal (not porchse normal, kid int he back normal)

3. When they put in the new clutch they replaced the flywheel, clutch, and the pressure plate. Bother the pressure plate and the flywheel had burn marks on then and the clutch was worn. This was a 2500 miles.

Is there anything else that could do this? Cloud I actually have linkage or gearing issues, and how would I prove it?

My driving is more than fine to have the clutch last 50k plus but now I am doubting myself and cant tell what is correct or wrong in how the car should feel. I know this post is a bit convoluted, but try explaining clutch release feel. Its pretty damn hard.

I am going to take it to an indie but wanted to get some thoughts here. There is a lot of good post on clutch work here but not as much on the basics. Since I am being accused of sucking on the basics it cant hurt to hear from other drivers.

I'm no pro by any means and am learning more every drive. I never rev match on the way up though. If you shift quickly then you will land in the right place with a quick smooth release. When I hesitate... I feel it and that's no good but when I'm deliberate it's smooth. Also, when accelerating, try shifting at higher revs. Shifting into 2k on a pull isn't ideal. These engines like to rev.

I think you already know what is right and wrong so from one car guy to another I will tell you that you are either overanalizing the clutch and can learn to live with it OR something is wrong (it is the later most likely).

I followed your last thread and you felt something different in the other 2 cars that you test drove so this stinks because now you need to fight ... which if you are like me it totally sucks ... you already have enough stress in life and now the parts that give you pleasure in life is now giving you stress.

You have no choice ... you need go to the dealer and tell them you are done ... you want another car ... if it were me I would tell them I will go the lemon law route so that the dealer does not have the problem but it actual falls onto Porsche USA but whatever it is it totally stinks you need to take this route on a car.

Sorry but what you feel it real and you need to take the next step.

Thanks for the advice and for following the threads. I bet if I did not come from motercycles where you are so used to feeling everything I would not notice. I think I am going back to them. Unless they can tell me what went wrong with the clutch and why it still feels off, then I wont keep the car. I am not gong to spend my time nervous and not driving and worse yet I am not putting in another clutch for a long time.
