Well, closing in on 29K miles (of which 25k have been modified ), and the clutch is starting to slip.

Given the hard driving and power the car is putting down, im surprised the stock clutch lasted this long.

With that said, what type of clutch do you guys recommend? I think it would be smart to upgrade to a stronger clutch, but I definitely dont want it to be super stiff as I drive my car often. Is there a stronger than stock clutch with stock feel available? If so, where can I get it and approx how much?

Thanks.

 

i second that question

 

Third.

 

We sell a single mass cluthch kit, consists of lightweight flywheel, HD pressure plate & disk, T.O. bearing and all related hardware. I believe sachs manufacturers it. It is supposed to be good for 700+HP. Unlike a lot of HD clutches, it has a super light pedal.
Hershel uses it in his TT as well as all the TT's Cargrqaphic Gmbh & RS tuning builds.

Hope this helps

it needs to be able to handle my stick driving ... which sucks. I think i am the king of burning clutches. any other suggestions?

 

***bump***

Come on, some of you must of some experience on this?

 

I went with a Sachs clutch from Todd at EVO. I didn't need to go with it as I had little miles...but with moving to stage 4gt he recommended it. I've had no complaints with it at all.

 

Go with the SACHS

 

If you're going through a clutch in 29K miles, better look into a TIP or learn to drive with a clutch properly.

 

I'd suggest Sachs Engineering clutch and LW fly, if you dont mind the gear rattle at idle. Hence the dual mass, 29k on a stock clutch is not bad , if you dont want to deal with the noise stick with the DM fly.
TIP: do the entire clutch including flywheel
and ring gear bolts as well as the guide sleeve, no matter which way you decide to go. Jay Putnam

 

Thanks for the info...

 

let's see... over 600HP on a stock clutch....the car has been modified for over 25K miles. I drive the car as often as I can and get on the boost throughout my 40 mile roundtrip commute...nevermind the number of meets, races (he he), etc.

If you didnt already know, that's going to put a lot of stess on a stock clutch.

Sure I could get 50K miles on the stock clutch.... if I drove like my grandmother

...there are many guys with 600+HP turbos who've gone through their clutch in less than 10K miles. I guess they dont know how to drive as well.

 

When I did the mods on my TT, I had to upgrade the clutch. When I went to boost the original clutch slipped. I also did the Sachs lightweight sports clutch kit. It cost around $2200. I love it. Not slipping. Yes it does have a rattle when in neutral but it is not that bad.

 

30k miles on moded car is actually alot of miles. I have a 920whp supra and I replace the clutch every 2 k miles (lots of drag racing). If your not good at driving Stick a light weight flywheel might not be great for you. Since there isnt alot of mass to the unit it will stop spinning when you stop at a light. Most of the time to get a smooth take off you must pump it 1 time to get it spinning before engaging into gear. Also You might notice a slight chatter since there is no damper in the flywheel. It like when you hit a metal bat on a wall and the virations travle down your arm. This is what it sends down the whole tranny. This might not be the case on 996 turbos but everyother car thats the case.

 

I don't know - the 996 clutch is the notorious weak point in the drive train. Generally speaking, most people seem to be getting around 40k from a clutch in a stock vehicle, assuming no drag racing, and normal driving techniques.

Throw a couple hundred extra horsepower, and I wouldn't be surprised if you get a little less life.

My last 911 went out at 38k miles, and I don't do drop-clutch launches, rarely launch over 1000rpm, and rev-match/heel'n'toe every downshift. And I don't ride the clutch either.

Given the alternatives (broken shafts etc.) I'll take a weak clutch as a compromise.
