I went with the steel flywheel.

The clutch noise is only noticeable when the clutch depressed while the car is stopped.

 

Sayajin, is it worse with the Aluminum or Steel?

 

Elite, did you use the EVOMs GT2 kit or did you have it drilled?

 

I used the Evoms conversion with the updated bracket.

 

Thats odd, mine only makes the noise WITHOUT the clutch depressed.

Honestly I think its about the same. It may be slightly louder wight the steel, but not by much. I ended up swapping out my Aluminum one for steel as ERP recommend it as the Steel one can take a bit more abuse and I had some issues.

Sayajin, Maybe my installer put mine in backwards?? When I depress the clutch pedal (pedal to the floor) it makes noise. If I put the car in neutral and let the clutch out it is silent.

 

^mine does the same. clutch makes a little noise when the pedal is pressed in.

 

I was going to say "maybe Steve could chime in." I know you have been experiencing with 2nd gear launches but, I like my car. What tricks have you found doing that in first gear?

 

ride the clutch for about 5-10 feet !!!!
the clutch cant burn out from that.
thats what its designed for...

hold 3.5 rpm, and ride the clutch HARD until youre doing about 15-20 mph. im telling ya, the clutch wont burn out or get damaged.

here's what cool about the clutch, it will let you know when its getting too hot by not letting you engage another gear. the 3 clutches will fuse together for about 30 seconds (this comes from the extreme heat). if you ever experience that, just pull over, put the car in neutral and turn it off.. wait a little while, send a text to your friend about how much of a bad *** your are, and repeat.

driving this clutch goes against what we've all learned since day 1 of driving a manual. if you "pop' the clutch during a launch, it'll bog even more than a regular clutch. so the trick is to ride it hard. it doesnt wear the clutch out.


you'll be able to do about 4 or 5 hard 2nd gear launches before the clutch gets hot and fuses together.
you'll probably be able to do 10+ back to back launches in first gear without overheating the clutch.

i broke my axle by popping this clutch because the engagement is a lot more aggressive than a single disc.

as far as normal driving, you have to ride this clutch a little more than a regular clutch otherwise the car will jitter.


this technique is pretty much what all PDK tranmissions do when they launch, the clutches arent engaging all the way in.

 

kind of like this...

you'll have to train yourself to accept that this is OK.

you want to do it just like this.

 

Best quote of the year right here folks! Lol, I wish I knew how to "give rep points" for that amazing sentence.

 

btw, that method of riding the clutch virtually eliminates stress on the transmission and axles. (thats why the pdk transmission on the 997.2 and 991 turbo can do 50+ launches back to back without any damage to the drivetrain).
once you practice a few times you'll be able to sling shot the car because riding the clutch makes the motor build boost faster. by the time you're off the clutch your engine is already at max boost.

also, if the clutch gets too jittery (this happens after a few days of daily driving), ERP suggests a few 2nd gear slipping starts to smooth the discs out.

 

You do not want the clutches to fuse together. So after you do a couple second gear starts shut the car off push the clutch in and sit there th your foot on the floor. That will allow clutches to cool down while disengaged. It takes some getting used to especially if you had the gt2 conversion done at the same time.

You got few things happening at the same time that really need adapting in driving style.

One is pedal is stiffer and wants to pop out quicker making it feel like there is less travel.

Two the clutch assembly is 28lbs vs 48lbs stock dual mass stuff so it's a lot easier to bog down and RPMs rise AND fall quicker. Just like any Lwfw setup u gotta give more gas when taking off.

Three the clutch is naturally grabbier than stock... However unlike Steve K said it does not engage harder than a single disc and in fact puts less stress on axels and drive train.

 

^ i meant if you just pop the clutch, the carbon clutch feels grabbier, hence the reason for wanting to slip it a bit.

 

Really, This is cool that both Steve K NY and prodigymb discussing this (Both have much experience with this.?) I respect both of you with my final decision. USP also, for keeping me up to date with the status of its delivery.


Steve K NY - Thanks for your input. I will try the 3K launch. With the new clutch, I notice that the shift are more rough. I am sure that this is due to the higher engagement that I haven't fully adapted to yet. I am confused though, I cant make the 1st gear launch yet, How a 2nd gear launch? Your axle breakage concerns me slightly. Maybe next time I fly to Melville, NY I can get a taxi near you to show me?


prodigymb - Love the GT2 conversion. This has given me a better feel of the clutch. It may take a lot of adjustment for someone that daily drives the car due to its heavy pedal but, I would compare the weight to an older V8 I had. I have the steel flywheel and haven't notice much change in RPM drop. I was expecting this though due to the weight change. I agree with you on the wait that I had, this clutch is made to last, I just hope that it wasn't installed backwards though. Sayajin has me concerned.
