Europ vs USA

Hello guys , first sorry for my english ,but i try.

I drive a TT-RS in europe and follow this topic .

My experience with my TT-RS is Now a few years old And i have a stage 2 car , i understand in USA its harder to get Some horsepower with the quality of the fuel. My car has 420 hp and 640 Nm at the wheels on stage 2.

I changed the intercooler And blow off. purge bij FORGE, And the exhaust from Miltek . Suspention Bilstein .

Now the clutch story...

Afther the stage 2 tuning the standard clutch even doesnt hold at the dyno test run , a big dip at 3000 rpm.
So,i ordered a upgrade from Sachs pressure plate and organic disc upgrade 550 plus ( Max 600Nm), i decided to stay with 580 NM.

By opening the clutch They called me to say my DMF was to much out of normal specs , so i put also a new one in it .

Sachs installed with new DMF ,

Not 1 Year later the clutch doesnt hold anymore with normal driving And one airfield drive day. Slipping at high gears at low rpm.

Back to zero , open clutch again , organic disc completely gone , cracks in pressure plate And heat trails.

Ordered a 4 Puck sinter from Sachs 650 - 700Nm for DMF , i keept the pressure plate , again They Told me the DMF has to much backlash(?) . I Saïd to put it in again , i dont gonna change it again.

The sinter holds very wel but the use of the clutch pedal is heavy And the driving daily is not easy , when you drive fast you know its the best combinatoin .

This summier , cracking noise at low speeds And driving away , the bearing pressure spring (oem) is not holding.
So the clutch must to be open again. I knew my DMF was not in good chape And my pressure plate was burned from last time. I decided to do everything at once .

After a good talk with TT-RS specialists from hperformance in germany i ordered a SMF , They told me the DMF Will never hold afther tuning And most forget the torque That ruines the DMF. They had a lot of cars driving with a defect DMF And They had a lot Of cars with broken crankshafts . Long story Told short , That torque And power = SMF

I ordered a custom made clutch for 850Nm so,i have enough for a stage3 till 750 Nm.
Last week,it arrivés And i was surprised to see a clutch i saw in the USA!.. But couldnt order

Their so called custom made clutch was a stage 3 DXD south bend clutch with the 8 pad sinter And springs. First i was angry , but later not any more because this was my first choice.

Next week i Goes in with the sach centraal bearing ,

If the oem pressure bearing had hold i still drove the 4 Puck from Sachs , it has a little ringel when the clutch comes up , but Notting more , fast shifting also

Now i am very curious for the dxd clutch .... The 4 Puck is very brutal , the 8 Puck Will drive smoother

Let's us know how the new clutch works out. There isn't a lot of information on how these clutch options actually perform and hold up in the real world.

That s also my point , not much info About dxd clutches , but hperformance has installed it in all the TT-RS They modified .
They startend to get rid of the DMF but there was only a stary disc ( no springs) , a lot of gearboxes broken,

Now the cooperation between Sachs And dxd Seems to work out. I Will post the results afther installing , And the condition of the 4-Puck disc ( 10000km on it)

My scenario is a little different. I went Stage 2+ for 10,000 miles with my stock clutch system. After 10k it started slipping in 5th and 6th gear. I slowed down to preserve the clutch system until I could find a stock like no noise clutch system that could handle APR Stage2+. Since southbend didn't offer this with the stock dual mass flywheel, I decided to call Cluchmasters. Kevin, mentioned they didn’t have a clutch system for my car, but if I could send him all the stock parts he could modify it, give me a hell of a deal as they were going to take measurements of all the stock parts to make their own kit. I sent them the stock pressure plate, disc, bearing and DMF. (Bought at Audi dealer)

They modified the pressure plate and disc. DMF was not touched. My kit is just a modified stock pressure plate and disc. It has been great!

As far as the one I see in the video, it looks like they have a different pressure plate but they added the self adjusting springs. This will keep stock-like pedal feel and adjustability. Also I see from the video that the disc has springs rather than being a solid disc. Also in the video they show a SMF, which I gather it will have some chatter noise.

You can call them for more questions, but I know if I need another clutch, I would go Clutchmasters as I’ve had them in other cars and have not had a problem with them.


I was thinking about the FX400 8 puck and keeping the DMF. I spoke with Kevin a few days ago and he told me that's my best option for drive ability day to day and race.

IIRC, Iroz thinks the most synchro friendly setup is the sachs 4 puck and OEM DMF. It was mentioned on here or on his facebook. If not that, just find the lightest disc you like and an OEM DMF. I don't have experience driving the 4 puck, but it is street-able from what I've seen. I think you can get the FX400 in 4, 6, and 8 puck? Wonder how much they weigh vs the Sachs.

From what people say the Sachs 4-Puck is street able, but I wonder if its ok running a sprung disc on the DMF. I need peoples thoughts on it; i know some people have taken out the 4-puck because of drive ability.

The Sachs 4 puck for the TT-RS uses an un-sprung disc, if the picture is correct... http://www.irozmotorsport.com/audi-ttrs-clutch-kit-sachs-performance/

I haven't personally driven a TT-RS with that clutch, so can't say how it does day to day. IROZ says it is surprisingly usable (off the track), but I am not sure if that includes stop and go traffic either.

Sachs 4 Puck

Well I just purchased mine from Hank so we shall see

Hi Guys,

I'm gathering from this thread that the Sachs 4 puck seems to be the best trade off for holding the extra power. It seems to be light enough not to harm the syncros as much from the rotational inertia. I'm not crazy about the "aggressive start" but then again I've driven cars with on/off switches for clutches with plenty of engagement effort. That being said my only worry is the longevity of the clutch. Has anyone done any long term driving of the 4 puck on and off the track? I'd like to get a good idea of duration expected between clutch changes.

Cheers,
K

The new sach 4 puck sintered is in. First impressions are. The pedal has a little more spring to it but not much more effort than stock. Engagement is higher up in the pedal travel due to the SAC function not being there anymore. Also this clutch hates being feathered. Seems like the more you slip it, the grippier it gets. Seems like it likes to be blipped gently (get the car moving) and let out quickly, but not letting it just pop up. Down shifts with rev matching is even better than stock. Only pet peav is the hill assist, since this clutch hates to be slipped at all it is very difficult to come away clean from a hill start. VCDS to the rescue. You can't turn it all the way off but you can make it release almost instantly upon touching gas/clutch. I caution you though, the car will roll back on you. Worst case if you aren't good with hills use the ebrake.

Vcds:
Abs (3)
Adaption (10)
Select drop down menu option- documented adaption channels
Select HHA

Values
0 - default normal
1 - release early - touch gas/brake
2 - release late - slipping clutch on throttle

Set value 1

When you have set the value push test and ensure it is the correct setting. It will display the option you set. Then hit save.

I know this is an older thread. I have had the Sachs 4 puck with stock dual mass in now for about 3k miles. Makes some noise here and there but plenty streetable. 2013 TTRS
