George,
 
the original side housing on the = flywheel end is=20 30lb including stationary gear, my compound housing is 15.5lb. Keep = in mind=20 that is has been adjusted to single Rotor requirements, like smaller = water=20 passage and a few other things.
 
On the water pump side, the difference = is going to=20 be somewhat less, because of the stationary gear.
 
Over all, a FF weight of 170lb is still = the goal,=20 and possible.
