M IIRC, LBS thrust = ("roughly" ...be gentle) 65% for its horsepower
equivilant.

100 lbs thrust will be about 65 hp. Is this close to being a workable rule
of thumb?

I understand it is speed dependent. At standstill it is 100 lbs = 0 HP and
at 600+ mph it is close to 100lb = 100 HP. I'm no expert so be gentle on me
too! ;-)
