there are "scratch designed & built" 150 hp-equivalent turboprop
engines on the market - check out www.innodyn.com - they flew to
oshkosh with a turbine equipped super cub (
http://www.innodyn.com/aviation/news..._05_05_01.html ).
furthermore, they claim to burn only slightly more than a piston
engine, which i find remarkable. they say they have a twinpac planned
which would output 300 hp.

If you read more carefully, Innodyne is taking existing turbines and adding
their fuel control system. Also, given the consensus that a turbine simply
can't offer the specific fuel consumption (or even close) to a recip, their
data on fuel consumption (or rather, the lack of hard data) seems suspicious
to me.

Innodyne has been in this game for years and to the best of my knowledge
have never delivered a single customer engine. I'd stay away until they
have a track record and can provide substantial independant confirmation of
their fuel consumption claims.
