Hi,
I'm running with the 164 12V flywheel on my 24V engine. Not a Dual Mass system.
I converted the 6 speed gearbox to operate a push type release bearing.
The clutch has been Ok to date, but feels like it may not have as much life as I thought.

I've been talking to Helix about their Organic and paddle clutches with uprated pressure plates.
The organic clutch should do the job OK and be much better for everyday driving.... The difference in torque capability using the 164 clutch vs the 166 clutch is only 10NM, so not worth all the hassle of changing the gearbox back to work with a "pull" type pressure plate.

The guy at Helix recommended changing the flywheel because of the hairline cracks.
I've been talking to "TTV racing" about making me up a new, lighter, steel flywheel... No problem, but need one to copy / re-engineer.

From what I can see on the forum, Neil (Turbonutter) has used TTV before and Rob (Sando) is already using a Helix Organic clutch and seems OK (although I'm not sure if it's a 164 or 166 variant).
