LWF on a turbo car - INSTALLED !
Hello
I am just trying to get some thoughts from the experts. I did speak to a few rlisters, but have received conflicting info. This post should not by any means show disrespect to the fellow rennlisters that have given their direct advice already.
Question:
Would a LWF mod on a turbo car make sense (cost vs benefit)? Do I have to reflash the ECU? Also, what thickness should the Flywheel be as there is a risk of breaking if to thin/light.
TIA

AFAIK, the positives are a bit better performance and throttle response. Engine revs faster and easier.
The cons are that some have reported some stalling issues, and somewhat more difficult to get the car moving from stop. My previous owner installed one with the Ruf Turbo R upgrade, and had it removed due to stalling issues.
I have never heard of any breakage of any LWF kit. For me, I'll probably wait until I need a new clutch, and then I'd probably reinstall the LWF kit that I still have in a box.
No ECU reflash required.

I echo the thoughts above:
1. Stalling is really not an issue. I suspect a novice with little clutch experience would have trouble with these cars in OEM trim. If you are used to the OEM setup, you won't have a problem.
2. A little easier to over-rev as you time your engagement on a fast 1st gear get away. THis is due to the reduced inertia and takes no time to adjust technique.
3. A little noisier at low revs in 1st and 2nd when under load - a mechanical, metalic sound that I don't mind. At all other times there is no difference in noise.
4. Weight saving - well a little bit in actual mass, but a very big difference in rotating mass - hence the small performance gain.
I would change only when the engine is coming out anyway, or if the clutch is due fro remplacement. I like mine but went for it with upgraded pressure plate because of power upgrade. If you have 400HP the OEM does just fine.

I don't think the stalling issue is due to clutch engagement but rather when coming to a stop, you stab the clutch pedal, and the revs drop a bit too fast for the computer and bam.

I have owned 3 993 turbos.
2 of the 3 had LWF.
I now consider it a "must do" mod.
the DMF just dulls the tactility of the car and its performance.....

I have to be very careful with mine when coming to a stop, otherwise it stalls. But then again, the entire clutch assembly (clutch, disks, flywheel, throwout bearing and associated mounting hardware) only weighs 14.5 lbs. That plus the manufacturer's claim that it will hold 750 ft lbs (1,017 Nm) of tq makes for a great track application. My ecu doesn't like it.

I have had the Andial LW clutch and flywheel on both of my 993 turbos with no noise and no stalling ever. It has always worked transparently.
I've never had a car with a dual mass so I cannot compare.
