Hi I'm going to need a clutch in my a4 2.0tdi 170 and was wondering if anyone's done a single mass conversion and how does it feel compared to the dual mass?
The car was designed to use a DMF and not an SMF.
The reason you should replace the flywheel with a DMF is three-fold:
1. You exert excessive torque against the crank shaft and eventually kill it.
2. You will exert excessive torque and vibration against the gearbox thus damage it.
3. You will experience a noisy and unpleasant driving experience.
Why?
Because a dual-mass flywheel is not only a flywheel but also acts as a mechanical filter getting rid of unwanted vibration and torque on the drive train, bear in mind the engine and gearbox were designed with the DMF in the equation so by removing it you are introducing too many variables that were not planned in to the design and despite so many people on forums dumbing down the need for a DMF, short term you will save money but if you keep the car long-term you will defiantly be out of pocket when either the engine or gearbox totally shats its pants.

If you are referring to rally sport/track day vehicles no, the have been modified to use an SMF for several reasons, the most important reason is safety as DMF's are prone to exploding on the track, also spin-up, a DMF will introduce some lag, as you know the flywheel is in two parts held in tension by springs.so all these audis bmw etc etc running big power with SMF have got it wrong ?
