Good point, George. I was looking for about 10-12gph.
Curious if a 550 will run smoothly there.
Just curious also, now that the other thread is going, have you determined
that high map/low rpm is more efficient than lower map/higher rpm.
From those frictional loss numbers Walter put out, it would seem so.
(In other words, rule of thumb for best efficiency: set the rpm
as low as you can stand it and still achieve required power?)

Colyn,
What RPM and fuel flow would you be using with the 28:” of MP?
At 28” x 2100 RPM, I can get the Hp down to as little as 180 or 190 Hp.
How
much lower do you want to be???.
Regards, George

I've been looking at long range profiles and noticing that a lot of the
interesting range is below
28" MP. I've heard this is the least that will keep you pressurized at
altitude.
Is this really true?
