Default RV14 Fuel burn

In cruise, what is the fuel burn on a 14 at cruise LOP and ROP on the IO-390 at 8,000?

LOP about 34 maybe 33 Litres per hour, or say 9USG per hour.

ROP at say 22" and 2500 RPM (mass air flow matters) you will be at 70% power and wanting at least 125dF ROP. My guess is around 45LPH or more? In USG say 12.8GPH probably.

You can just about bank my LOP number, the ROP number might be slightly off, but not much.

Hope that helps.

Data is not at your specified altitude but the original prototype is still providing performance that matches that described in this old thread.
