Hi all,

My first post, but i've been lurking a while.

My ride is a 2001 A4 1.8T Quattro. The only major performance mod I have in there now is an APR chip.

Here's the deal. My stock clutch is starting to give as is evident from high rpm and lack of power transfer.

I'm looking to get a Stage III or IV SB clutch and probably going to pick up a new flywheel. I believe the stock FW is dual mass. Should I get a single mass FW or stick with similar?

Any suggestions on clutch and FW appreciated.

P.S. I am in the Seattle area

 

if all you are getting is a chip, no future plans to upgrade your turbo, just get a stage 3 and you wont wear that out again. is your clutch slipping? im not sure what you mean by high RPM.

you should probably replace your flywheel while your in there, you can get a stock dual mass (25-ish pounds) and an unsprung clutch, or a lightweight FW with a sprung clutch. i would go with a 15 or 17 pound lightweight if your not replacing with a stocker.

 

Thanks for the reply.

I will probably end up upgrading the turbo somewhere down the line so stage 4 clutch is probably a good bet.

What I meant by high rpms is that when I press the gas I don't get a full transfer of power and it seems my rpms are climbing excessively and I am not gaining as much momentum as normal. I guess this is slippage? It's most noticeable when going up hills or shifting to 4th and 5th, although I can also notice it in lower gears if I floor it, unlike before this problem started happening (about 2 weeks now).

What exactly is a sprung clutch and what is the difference in weight for a FW?

I was reading that dual mass FW allows for less vibration and smoother shifting, and a single mass can bear tougher loads, is more durable, yet feels more rough

 

yes that is the clutch slipping.


Sprung disk. It is used with a single mass flywheel and helps make the transfer of power to the driveline a little smoother.






Unsprung disk. Used on a stock flywheel since the stock flywheel bolts are flush with the flywheel surface, but can be used on a lwfw if being used as a race clutch.




Stock flywheel is right around 26 lbs, the billet steel flywheels are 15, 17 and 20 lbs. The reduced weight will allow the engine to rev up easier making the engine feel more responsive. That drop in 6-11 lbs doesn't effect the engine enough that it makes the car hard to drive on the streets, that issue comes with the much ligher billet aluminum wheels that range from 9-12 lbs. The lighter the flywheel the more you will hear the chatter of the clutch.
