Thanks very much for sharing. Interesting innovation.

Do you know how the 5/6 gear chatter manifests itself?

I'm no expert :lol: but in laymans terms, our factory flywheels are Dual Mass types. The RS flywheels are Single Mass types. The latter, in being so much lighter, aren't able to 'dampen' the sound of the transmission and so we hear the gears 'chatter'. It's the norm for RS cars. This noise, is heard predominantly at idle and at low revs through the gears, and a quick search on 911uk and Rennlist will show its a constant talking point for owners considering the RS LWF.

With this 9m 'mid-weight' flywheel, in terms of weight, sitting between the factory Dual Mass and RS Single Mass flywheel variants, they indicate the 'chatter' noise is vastly reduced when compared to the RS one, and is only heard in 5th and 6th gears if at low revs (i.e. its a selling point...!).



Edit to add:

I have found a quote from Colin Belton of Ninemeister who answers your question far more succinctly, of how the chatter noise in the RS flywheel manifests:

The noise is caused by backlash in the non-engaged gears being shaken by the torque impulses of the engine at low rpm. It's totally normal and does no harm whatsoever, however if you don't like the noise because you drive around in 4th gear at 30mph all the time, then clearly the LWF package is not for you. This is why Porsche deemed the LWF suitable for the RS Clubsport only and an option on the 993 RS lightweight. If you wanna go faster there is always a price to pay somewhere along the line.

(and a bit further down on the same link)

The classic noise band is 1000-2500rpm at high load in a high gear (4th), so if you are crawling along in traffic and using the low end torque in 4th driving it like an automatic you will definitely hear gear chatter with a LWF.

I remember the first time I drove my 993RS CS with Marc on board - shocked at the racket from the gearbox coming through the bare painted rear deck he tried to persuade me to pull over immediately as he was absolutely convinced that the gearbox was falling out of the car.....
 
Thanks very much Chet. Very good of you to share all this info.

After more thought, common sense needs to prevail. I've already had enough scope creep with my 993, and I'm really keen to get it back, so I'll skip this time. I'm itching to jump back in my car again, and just enjoy for a while before considering more changes.

I am very curious how others get on with this. So please share your feedback when it's installed. Have fun :thumbs:
 
I'm not interested in this kit as I don't have a 993. But I do have a 997 and have just installed the lightweight version on mine, and am absolutely thrilled with it. Its just a joy to drive now, and adds to the pleasure hugely.

Mine is the full lightweight version, but also made by TTV as I'm guessing this one is. Its certainly a quality piece of kit for sure.

So if its anything like as good an improvement as it is on mine its a massive recommendation from me!


:thumbs:
 
Count me in. 9M are only down the road from me so I might pop in and see if they have a car with one fitted that I could take out for a drive and give my views on.
 
I've always wanted a LWF and the clutch on my car is approaching 50k so it's probably got a few years of life left.

I'd only really want it done as a package though....food for thought.

£700 ish for a flywheel, that seems very very toppy? is that just 'scene tax'?

It does seem a little toppy, however I have no doubt the quality will be there...

For example prices on Design 911 are as follows:

993RS Single Mass Flywheel - £290.03
993 Dual Mass Flywheel - £417.48

I'm sure they're all good quality, just wondering what the difference is for the cash?
 
There's been quite a lot of interest, and a few (valid) technical questions thrown up by others. Any interested party should refer to the new link in the first post to follow latest developments & ongoing dialogue.

That's one for your indy to answer!

Agree they are not cheap. Can only assume with this being positioned as a 'mid-weight' flywheel, for which there aren't too many choices, there is a premium.

Given some of the questions being posed, your first hand feedback would be very interesting for us all! Believe they have a VR 993 and a 964 with non-VR 993 engine/ECU running this flywheel. Let us know how you get on :thumb:.
 
Having a 911 restomod built on a 993 donor car. Would be very interested in joining this. We've increased engine to 4.0 - does that impact the compatibility of the flywheel? (Apologies if that's a silly question..!)
