dual mass flywheel: LUK vs SACHS..?

[jb92563]

Thanks for the explanation of the DMFW.

So you say the DMFW can wear out, what symptoms of that would you notice, just out of curiosity.

So are there light weight dual mass flywheels as well?

Seems prudent to keep the harmonic balancer function but at the same time a lighter weight would allow faster acceleration of the engine.

So if I understand correctly the LWFW does NOT have any harmonic balancing functionality?

I also wonder if the flywheel balancing can be done dynamically on the engine or statically before its attached?

Perhaps that is indy mech thinking and only worth it for racers if at all?
