How's that second Dolmar working out? The Echo would run on the AVgas, but you wouldn't of been happy with it. The higher the octane the slower the burn, so to compensate the ignition timing needs to be advanced in order to realize max benefits.

That little Echo just didn't have that much advance built into the stock module...I could hear the engine get lazy on the avgas.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
