Thanks Richard,

George,

the original side housing on the = flywheel end is=20 30lb including stationary gear, my compound housing is 15.5lb. = Keep in=20 mind that is has been adjusted to single Rotor requirements, like = smaller=20 water passage and a few other things.

On the water pump side, the = difference is going=20 to be somewhat less, because of the stationary gear.

Over all, a FF weight of 170lb is = still the goal,=20 and possible.

Richard,

Very good outcome - will you give = the weight=20 difference between the cast iron and the composite = housing.
