    You can get 5gph out of an O320 with electronic fuel injection and ignition. When I'm chasing C182's I get 5gph at about 145 mph in my Glasair II. If I'm cruising WOT (Savvy style) and 2400 RPM I get 165 mph at 6.5gph. I haven't tried 2700 RPM. My Glasair II has 500 useful load with full fuel. The new iS 915 Rotax in a lighter composite will probably put you near 200 mph under 5gph in a lighter composite.
