This is not a new thing. The 350z and 370z both have the "marbles in a can" or "cement mixer" sound from the clutch/flywheel setup. My twin disk doesn't sound that bad, but Donny's (UPREV's Mechanic) super single w/ lightweight flywheel sounds like the "cement mixer" especially after everything is up to operating temp.........
