Brief Description: Fuel Testing

Fuel Testing: Fuel Flow Calculations: Lycoming manual shows between .54 an .49 BSFC. Used EAA default .55 to be conservative. Max Fuel Flow 160hp X .55 BSFC = 88 lb/hr. Pounds to gallons 88 / 6 (specifec gravity of avgas) = 14.67 gal/hr. Preasure / Fuel pump dependent aircraft EAA recommendation is 125% of max fuel flow 14.67 gal/hr x 1.25 = 18.33 gal/hr. 18.33 gal /hr / 60 mins = .306 gal /min. .306 gal/min X 128 oz/gal = 39 oz/min (This is the minimum fuel flow for all testing).
