A bone stock 340 (not Titan as they have not released HP curves that I know of) normally aspirated, magnetos, fixed pitch, specs at .46 lb/hr at BEST economy which is at 125 bhp which equals 9.58 gph. I know the Titan is better and especially if injected and with electronic ignition and a constant speed prop - but 5.5 gph would be a fantastic accomplishment at 75% power.
YMMV, Greg
