...in addition to burning up to 25% less fuel than a Continental or
Lycoming. Other than changing my oil once every 25 hours, this engine
requires NO maintenance.<<
I don't disagree with most of the post as I am sure there has been a
tremendous amount of effort put in to make the installation a good one. I
suppose one could even carry full fuel and 4 passengers while carrying an
engine that is significantly heavier than the original. With an
experimental you can certainly pick your own gross weight and say it will
carry what ever you want. None of the "standard" IV's can carry full seats
and full fuel and stay below the advertised gross so I don't know what kind
of math is used to make it work.
While I am an auto engine enthusiast, I have to say that NO WAY can any
spark-ignition engine burn 25% less than a standard Lycoming or Continental.
While these engines may not represent the latest in technology they are
quite efficient and reliable. An auto engine, because of the ability to run
a slightly higher compression ratio for the same fuel, might be slightly
better, but only by maybe 2%. I might even believe 5%. But not 25% -
especially not on 92 octane. NO WAY. Just not thermodynamically possible.
