Keep in mind that in Oz temp is generally above ISA often well above and that slows turbine powered aircraft down. The 215K in the pretty brochure is suddenly 195K or worse.Seems to be a lot of cash for a modest increase in speed. The NM/litre is only 65%of a normally aspirated 210 . You'd get a lot more bang for your buck installing a continental io550p. Ignoring fiscal common sense I love the climb rate and the TO and landing distances.
