With that high compression engine? You can't even get an STC for an
alternative fuel.

Where STCs are not a consideration, high RPMs and less than full MAP can
allow the use of autogas. Performance may take a hit, and sometimes timing

To me performance is paramount.
I'm building the G-III to go as fast as possible. Long haul and some
serious play.

I don't even run the Debonair under 75% except for maneuvers, a rough
ride, and landing. That engine IO-47N (260 HP) doesn't qualify for an
STC either. My goal is to get similar HP to the one shown in
KitPlanes this month.

must be retarded for the turbocharged engines, but it works. I ran autogas
in my first Aztec (NOT US registered!!!!!!) for years. The only difference
was that I had to turn on the boost pumps on above 7000' for vapor lock.
