When Mike Belfer was building my engines he would put it on sometimes, and
sometimes he would not. I never understood the whys and wherefores of that.
To a non-wrench type like me it seemed like either you should or you
shouldn't. 'Sometimes' didn't make much sense to me. But we run harmonic
dampers on our engines now. We have gotten them in the past from Ken
Gillanders at British Frame and Engine. I always felt they were a 'good'
addition to the TRIUMPH four cylinder engines, and a 'very good' addition to
the sixes. Just seems to me that the longer that crank shaft is, the more
important the damper would be. Anyone who has ever played with a Gyroscope
ought to follow the logic. I forget who it was, but someone on the list was
describing the use of an MG or A/H based fluid damper on the TRIUMPH engine.
If I remember, I guess they worked pretty good, but if I remember correctly,
they were not standing up long term very well.
