More to the point, supposedly flat cranks have enormous vibration problems,
which are exacerbated by larger displacement. Current materials can
handle the vibrations when the reciprocating masses are small (3-liter Ferrari,
etc.) but when you start talking about whopping great pistons and rods like
in an American V8, the masses become too great and a flat crank would simply
fail.
Or so I've been told. You would think that if a flat crank was feasible
in our applications, somebody with deep pockets and a desire to be fast (or
different) would have done it. I suspect the testing has all be done
already, and the idea proven to be a failure.
Does anybody know otherwise?
