Subject: IO-550N take off fuel
flow
Lean of peak for the IO-550 N (8.5 compression ratio) horsepower is
15 times fuel flow in gallons per hour. This was the basis of the LOP flow
rates in the table above. I figure that with 10:1 compression which
produces about 4-5% more horsepower, the number is about 15.6 horsepower per
gallon per hour.
I spoke with GAMI and for my TSIO550 they use a conversion for FF to
HP:
13.53 hp/gal for 7.3:1 and 13.73 hp/gal for
8.5:1.
