Yep, the

Walter,
Better, but never very good.. Gary's comment is also slightly suspect
because Taylor indicates injected engine air temp can be and has been measured
at the cylinder (It's Sunday, and I am tired of Google searches at the end of
the week).. Carb engines are notorious for the poor F/A balance in each
cylinder - air just doesn't seem to make it around the different corners to get
good results.. I have been reading Taylor and simple comments will no
longer work for me without data. We can have our beliefs to
be whatever we want but injected engines can achieve a greater
efficiency than carbed ones....besides the splash that is vaporized on hot
cylinder surfaces, there is clearly atomization, atomization that can be
enhanced by proper inserted air under pressure or, no additional air is
required at all if a sophisticated multi-port electronic injector is
used. Honda will show the way........
Anyway, I give up on this thread because Octane and timing, valve
characteristics and induction mixture swirl are at least as important
as air temp and compression ratio when one is thinking about detonation.
There just ain't no simple answer. Experimentation is still
possible....
My personal brain timing has now been retarded to avoid
self-detonation..........
