The static RPM is 3150 on my Great Plains 2180 VW rated at 76 hp with an Ed Sterba 52 x 52 prop, Compufire electronic ignition with mechanical spark advance (32 degree max), Zenith carb and four-pipe straight Dragon Fly exhaust.. Cruise fuel consumption is 3.7 gal per hr. Total time on this engine is 12.6 hours. Sid Wood

Rule of thumb would indicate you are pulling 44 hp at that fuel burn or 60% power setting. (3.7x2x6=44hp) (44 / 76 = .58 {assuming 76 hp is correct} ). Anything less then 76 hp max rating means you are running at a higher percent of power. If you have a fuel flow meter you could go max power and see what the burn per hour is and get a close estimate of the hp output (fbph x 2 x 6=hp). Example: If I run my 0-200 wide open (2750 rpm) and get 100 hp my fuel burn would run right at 8.3 gph, very close to the book numbers. (8.3 x 2 x 6= 99.6 hp)
