Torsional Vibration and PSRU Design

"Gordon Arnaut" wrote

Cog belts are noisy, tend to fail more quickly and are expensive -- and
they are only needed in applications where synchronous operation is
required, such as in driving camshafts.

Today's multi-v belts -- the kind used to drive engine accessories on
newer cars -- are highly efficient and can handle huge amounts of power,
up to 1000 hp.

That is the first bad advice you have given.

It is interesting to note that the cog belt is the drive of choice, for
manufacturers of V-6 and V-8 redrives manufactured today. Perhaps they know
something that you don't?

Belts are lasting 200 hours with no sign of wear, BTW.
