What is the ratio/relationship in size of the
prop to BUC? Might be a good reference for something to look out
for.

BUC is much
larger at the bottom, than anywhere else. I would guess that the last
14 inches of my 68 inch prop extent beyond the cavernous inlet
opening. This is no doubt helping with my cooling, but has also
got to be blocking some thrust.
What's your fuel flow? (ultimate
test) If you are tuned even half right,
fuel flow will approximate
hp.

I wish I knew. Tracy
has been holding my flow meter hostage since June
:-)
Rusty, I think the prop adjustment is the
culprit.. (in addition to the piggy factor) Try moving the pitch to
about 20 degrees measured at 75% of radius. Compare the results to the
more fine setting and you may discover you are generating a lot of power but not
enough thrust with the current setting of 12-14 degrees.

I don't believe the prop is completely flat on the back
side, with the exception of the very tip. Warp sends a protractor
with every prop, and it's meant to be used only at the very tip.
Basically, you zero the protractor on the hub face, dial in the pitch
you want in degrees, then twist the blade to match that pitch.
The number itself is irrelevant to anyone but Warp, but it's a repeatable
measurement.
Cheers,
Rusty
