According to Ken Gallanders, noted TR3 authority, there are some nasty
harmonics at 5,300 or 5,800, I believe, which are far worse without the fan.
There are additional harmonics at other rpms, but not quite as bad as this
My understanding is that you would be ok, without the fan, if the rpms
remained below the redline. There is a harmonic balancer available, if you
plan on higher rpms.
All my knowledge is second hand, others can provide better info. If you
don't get the info you need, let me know and I will try to obtain more
