The first thing I would look at with a corvair on a kitfox
is weight & balance, you can push a
light engine further from the CG to get back in balance but if the engine is heavier
then what is in the envelope pushing it to the CG can create geometric issues.
i.e. hitting the fire wall, cockpit etc. finished installations are in the 210 –
230 lbs ball park. If the w&b does not work out with this combo I would
look at the VW engines.
I’ve worked with William Wynne on a few of the new products
he has come up with, his web site is the flycorvair one listed above. Over the
past 2 decades he has honed the engine into a very high quality airworthy power
plant, with total flight hours / in service engines to back it up. he does have
complete engines for sale or build to order engines. Note: my day job is an
aircraft gas turbine engineer for Pratt & Whitney.
I’m using a standard o-164 (2,700) on my project. I put
together my own engine with his help & only live a few hours away, but in your
situation a finished engine would probably be the best path.
I’m not a pro on the engine yet but I could answer the
Hope this helps,
