Dave- Using the WOT numbers for gassers skews things worse than they actually are. Many if not most gas engines enrich the mixture at full power to protect pistons, valves, etc from heat. Go to cruise and mixture leans and hp/gph improves a little. How much? Who the heck knows, they don't publish any curves!!!

Annoying.

Even CR diesels efficiency drops some at full power, but for different reasons. And not by much.

Gives me the urge to buy a decent dyno and figure this stuff out for myself!!! Probably not my best idea of the week...
