CanBus: now rotary bashing

[Bruce]

Thanks,
and,
Gasoline just holds so many bonds that can be broken and reassembled.  The
chamber reactions are pretty much a fixed combination of ingredients.
There is just so many up and downs to all the various aspects of things,
that you'll wind up with a tie.   It's all fuel dependent at this time.
How every you play the wasted heat issue to recover some of that energy is
going to be the tie breaker.   Hence, the turbo.   Then you just get into
optimising it and it's subsystems.
  You can play the 8 valves per chamber, kind of engineering exercises, but
what happens in real life, is what really is going on.   The new ZO6 vettes
are just living proof that you don't HAVE TO HAVE, 4 valves per cylinder,
variable cam timing, yada yada.  AND it seems that lots of them are getting
26+ MPG.
   Just common sense will show what actually works.
   (The above is just in general response to street type vehicles)
