Subject: REFLECTOR: Fuel Consumption Performance




I recently traveled to Oshkosh with a friend who owns a Velocity 173 with fixed gear and a 200 HP fuel injected Lycoming.? He was able to reduce gas consumption to 6.2 gallons per hour at 10500 feet and maintain a speed of about 125 nm/hr using LOP techniques.? 

?

I am building a XLFG -5 with constant speed propeller.? I am looking for what one might expect in minimum gas consumption using LOP techniques at a density altitude of 10000? feet.? I am considering the Lycoming IO540 260 and 300 HP, as well as, the 310 HP Continental 550N.? It has been suggested that if I buy one of the more powerful 300 HP engines ?I will just be able to run with less throttle and bring the fuel consumption to a reasonable level.

?

I would appreciate any comments / experience of the builders and owners with a similar XLFG configuration. ???
