Not sure about harmonics, but on a similar note I was reading a blurb in Road&Track a while back about the 50+ lb flywheel on the M5. Seems to meet emissions they have to idle lower than what the engine would really like, so to keep the vibes/tranyy rattle down (it is a BMW after all) they had to crank up the weight of the flywheel.
