Hi,

I have a 1992 3.3l turbo and it has a dual mass flywheel. the car is smooth, but I am wondering if I can fit a RS clutch in? Will there be any gearbox rattle/knock back? and how much difference will it make to the performance?

Dear Mike,
If you are going to install a RS Clutch assembly I would recommend the single mass flywheel to go with it. I would see little benefit of installing a lightweight clutch and still have the slug of the flywheel. To gain any benefits you have to lighten the whole load.

hi Adrian,
just curious, do you know who make the best light
weight clutch?

 

Now that is a toughie. To be quite honest I have heard no complaints about the Porsche Factory RS clutch. I know this works well in a Turbo because it was fitted. I also hear good things about the Sachs competition clutches. However these are not cheap. I am sure there are much more informed and knowledgable people who have actually done this work on their Turbos. I would seriously advise you to shop around but please consider the factory parts. I know they last quite well.

Hi all,

Just interested as I know as the dual mass flywheel takes all the vibrations out the motor, I would lighten the whole assembly (clutch, flywheel, pressure plate).

A lightened flywheel and clutch is worth about 10% increase in power because of the Dynamic mass, that being that a rotating object has 4 times the mass of the stationery object. therefore if you can reduce the rotating mass then your motor will spool up quicker.

Thanks guys
Mike
