continuing....

it is my personal belief that the M96 doesn't really have issues with torsional harmonics. a lot of people make the case that the dual mass flywheel & its elastomer serve as a harmonic balancer. i don't think they really do. in general, torsional harmonics go out of control at the FRONT of the motor because the driveline serves to damp the other end. i think the DMF was designed to reduce driveline noise. this becomes readily apparent when you swap in a single mass LWFW. even with a sprung clutch, the 5-speed gearbox is NOISY without the DMF. if porsche was worried about torsional harmonics, they would have added a harmonic balancer to the front of the crank.

more in a bit.
