Anyone seen this engine or heard about this company? Looks like they are still under development but could be interesting for the next gen of experimental and light sport aircraft. Sounds pretty "affordable" at 40k a piece

Nice little engine , comp looks like one of Garretts latest ones .

How well do you guys think the efficiency will be with a single centrifugal compressor?

It should be OK if they're running a high enough Pressure Ratio , but it certainly won't be as good as a piston engine.
