Right, a real crank UDP reduces rotating mass AND reduces the drive speed of the serpentine belt, underdriving the accesories, hence the term UDP, lol. My point being, rather than try to make a crank UDP with the proper harmonic balancer function, simply use the existing one, and put UDPs directly on the accesories. Come on Todd, it isn't rocket science here.

Balance is the Key. rarasvt@comcast.net
