I agree that it is a good idea to check performance with plane in final
configuration before making final cut on the prop.
But,, keep in mind that the HP absorbed by a FP prop
is proportional to the CUBE of the RPM. The difference between 5600
and 6300 is HUGE.

Are you trying to set max speed cruise at
some low rpm like 5000?
Not at 5000. I've
already turned it at 5600, and that was without wheel pants. Clark designed it
for an rpm of 6300, so I'm not that far off. The general idea was to
optimize for cruise at the expense of take-off and climb. Of course I
plan to get it cut back, but I want to get some better numbers with the pants
on before sending it back. I'm thinking of getting a 2 blade backup prop based
on these numbers before sending the 3 blade back so I wont be grounded for 4-6
weeks.
Thanks for all the
other input on octane, boost etc. etc.
