I saw this ad in the recent edition of Flying. BT's very own Doug Rozendaal wrote en excellent article on a piston-powered Evolution prototype back in 2010: http://www.kitplanes.com/issues/27_9/fl ... 308-1.htmlI thought this part of his article was both interesting and a bit scary: "The climb through FL180 at the same 140 KIAS—but at 36 inches MP—had the fuel flow down to 25 gph and a CHT range of 345° to 469°. Do these temps seem high to you? Well, Lycoming says that the IE2 engine can operate and survive with much higher CHTs than we are accustomed to or comfortable with. The protection provided by the elaborate sensors and precise engine control allows operations at temperatures that would destroy a manually regulated engine." Why would "elaborate sensors" change the physics of heat and metallurgy? This is also from 2010: https://aerospaceblog.wordpress.com/201 ... evolution/Note that the link at the bottom of the ad goes to a dead site.

Two years ago, Lancair told us that the only piston Evolution was the factory one which was instrumented as the test bed. They said that everyone wanted the turbine engine. They did quote the specs Michael posted (and the engine was at least $400,000 less).

where do you see that? i did some research and i could not find any such deals, usually, the cycles were the killer on the "core" engines available

They eventually got tired of waiting on Lycoming, converted that one to turbine and sold it. Now that Lycoming says the engine is ready they've done another piston Evo which will be at Sun n' Fun.

The engine was not sorted out when I flew it. If they have it figured out, it should be a great airplane....
The turbine is a fantastic airplane!

Obviously they're not flying with the Lycoming IE2 .
That said, the specs are calling for 270K TAS @ FL250 - that is very close to the turbine but at 1/2 the fuel burn ! Lancair are now quoting max speed of 240 kts at FL 250. Estimated cost is $875,000. http://www.evolutionaircraft.com/aircra ... on-piston/

Username Protected wrote: Overall specs are incredible but can you really run a piston motor at such high temps and get any meaningful life out of it? The range and speed are amazing! At that time their company line was that a pilot could not run it like that. But with the computer controlling the fuel and spark on every cylinder individually, on every revolution, the engine could survive at those temps...... But, again, it wasn't sorted out when I flew it.

We just got one at our field. I have not flown it yet but first hand accounts report that it's quite a machine. Almost 8 hours of fuel. I believe it's at Sun in fun now and will be at Oshkosh. It made the local paper, you'll have to overlook some of the reporting. http://www.gosanangelo.com/news/local/s ... 88521.html
