Good work James, you have it nailed in that post :thumb:
I'm certain that rpm won't just be bolting these on and haven't heard any reports of their cars cranks failing.
Who knows what the DMFW comes with out of the box :?: perhaps by their nature they don't need to be too well balanced as they simply smooth it all out until the springs inside fail. David gave me some good figures of how a few grams adds up when you move that outside the centre line of the crank and spin it at 6500 rpm. A bit like pulling G in an aircraft and the multiple times things weigh (for comparison).
Flip side, Infrasilver's crank broke when the dual mass flywheel failed (can and does happen and that's why they say change it when the clutch is at end of life)
Pays your money and takes your choice (or should that be chance)
I'd love to see some knock sensor graphs for our engines (back to back for both flywheels) as by design I thought the flat 6 was inherently well balanced.
