Surprised, other than the cost, no one talks about running a turbocharged motor at elevations above 10,000, in a RV-9.
No talk about ever running a Rotax 915 IS rated at 141 HP, and it's not losing HP at those elevations.
True, your climb rates won't be as good at lower elevations, but probably past 8000 feet and above, where the RV-9 wing does so well, it's still making good power, where a normally aspirated engine isn't. And it's pretty much FADEC capable. Fuel injection.
And to add some blasphemy, the engine is not a design from 1951 or 1953 when 320's and 360's first came out? Fresh design with current technology, manufacturing techniques and metallurgy. Car engine design, snowmobile engine design, jet ski design and other gasoline powered toys have not stood still. Any fresh new designs out of Lycoming lately? Just asking, for a friend. Wink.
Thoughts?
Sorry I am so simple minded... but if you want a o-360, why don't you build or buy something designed for it, a RV-6 or RV-7? Making something capable of doing something it was never designed for, is lost on me. Get the right tool for the flying mission.
Don’t get the message here. Apparently advocating supercharged experimental automotive/snowmobile power. And supercharged engines were the ones that the extreme >Vne air speeds were tabulated in the Kruger article. Yet the normally aspirated O-360 is somehow wrong.
