Uh...
Make that 0.5 gal / Hp-hr...
Thanks for pointing out the error in my units, Mike!

Um, this still doesn't make sense to me:
0.5 gal/hp/hr x 100hp = 50gal/hr? Am I missing something? I would think the
burn should the be 0.05gal/hp/hr to get 5gph @ 100hp.

I believe the rule of thumb for thermal efficiency of aircraft engines fuel and
horsepower is .5lb/hp/hr which in the 100hp engine equals just over 8GPH (50
pounds/6 pounds per gallon= 8.1). which makes sense since it only generates 100HP
at full throttle at sea level and we would rarely operate in that window.
Usually we are powered to 75% at cruise which would give the more reasonable
5GPH.
But don't quote me on any of the above.

perhaps 0.5 lbs per hour. that is a typical specific consumption for a piston engine.

No need to hypothesize. I get right near 5gph....cruise at 2700. Admittedly, I
have my timing backed off just a bit from the 32 deg max, so may be getting a
bit under 100hp.

Specific fuel consumption, as I remember it from Tech days so long ago, is
measured in pounds per brake horsepower per hour. As mentioned by others, it
usually is about 0.5 lbs./bhp/hr.
