REFLECTOR: Fuel Consumption Performance

[Tom Tolton]

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.
