    Harmonic Dampener/balancer?

    So, I've noticed ever since the swap that if I rev the car up in neutral, clutch in or out (doesn't matter), to about 2300rpm I'll feel some rather significant oscillation/vibration.

    The flywheel/pressure plate assembly was balanced before I installed the clutch/trans. All the accessory pulleys are spinning fine, no wobbles, the bearings seem great and the tensioner and idler pulleys are both new. The vibration dampener (crank pulley/timing ring) can't really be installed wrong. Any ideas? Is there a harmonic dampener or something that I'm missing? I'm getting paranoid that it's my oil pump sprocket chattering around due to my OPN backing off or the pump stud stretching, but it's too noticeable to be something like that. I'm sort of at a loss.

    what are you using for engine and trans mounts?
    If urethane, try retorqueing the fasteners again.
