I just bought an ATI to put on my car after the A/C compressor grenaded recently. I'm hoping that the underdrive can make the new compressor last with the relatively high RPMs from my 3:90 gears and raised shift points. Up until my first stroker engine swap a couple of years ago, I ran an SLP underdrive balancer for 2 valve cars without incident.

Of course I have stated many times that I don't think automatic cars have ever been affected due to the torque converter acting as an auxilliary balancer on the rear of the crank. The lower stock redline probably doesn't hurt either.
