No never considered a metal prop - don't believe I could get a
metal prop 76x88.

Ed, that prop is simply a monster. (I
clearly have prop envy). The fact that you fly with it is a
testimate that you must be making more power than the typical
O-360.

Well, Dave, I sort of hesitate to make any such
claim without dyno data - however, my fuel flow indication on take off
(17+ GPH) and my improved ROC (1800 fpm) for my overweight beauty
indicates I could possibly be making in the vicinity of 190+
HP.
I took off at a gross weight of 1783 lbs this week ,17 lbs
short of my maximum permissible. Rate of climb at that weight was 1200
fpm, so weight does indeed affect ROC {:>), but still more than
adequate. Yes, I do burn off fuel to get within Van's recommend
limitations before landing.
It is interesting in that folks at airports I had
flown into previously with my smaller prop have noticed and commented on the
"Monster" prop. It is 8" longer and appears to stick out much further
beyond the cowl. So I am probably getting better prop efficiency.
Being able to turn a bit more rpm increases the HP as well.
