I am sure turbine power is the way to go above 400hp since those planes are usually distance driven with the fuel capacity tailored as such. That is also when piston power loses reliability(except LARGE radials) I think we are getting some experimentals that are getting big enough to play there. I would love to get something beside a 540 or M-14 for my plane but the LS1 chevy V8 is the leader for me as far as alternitive power. Turbine dreams but chevy check book and fuel storage.

The Lycoming high compression engines i.e.. 160 and 200 HP engines are not approved for auto fuel while the 150 and 180 LC engines are. I am sure there are people out in the field using it. I didn't mention the 540 engine group because it covers a wide range of HP and I'm not sure which ones are considered high compression and which are not. Right now I'm paying $2.25 for 100 octane and it isn't worth the hassle as 91 oct. is $1.65. Also every carb that I've torn down that was using auto fuel has had some degree of corroision in the bowl.

I don't remember who owns it. In automobile engines, 92 octane mogas can be used at compressions up to 11.2:1 if the ratio is kept rich enough and the ignition is somewhat retarded.
