Need to buy harmonic balancer for new rb 493" race motor. Which is the favorite or best recommended? ATI. BHJ, TCI or Fluidampr?
Ran the Fluidampr for years w/no major issues but always had a little vibration then went to ATI and no more vibration FWIW. Also what always made me nervous was why the Fluidampr didn`t want you to balance your rotating assembly w/it on and no mention of that on others......
Because at relatively low balancing speeds, you don't generate enough force to center the inner ring in the housing.
Funny thing is a converter is much the same.
When I balance clutches, I always zero the disc. You'd be surprised how far off a disc can be.
