You are all right and wrong. Normally aspirated engines make more power when they
are cold because they can injest (sp?) more air and fuel. But Blown motors don't
have that problem --- run 'em at 250 or higher -  if you can stand the detonation.
CO and NOx are both low(est?) at 14.6 afr. Each goes up quickly on one side of
14.6, so 14.6 is the balance point for emissions w/o cats.

My belief is that more fuel can be vaporized and burned at higher fuel temps w/o
detonation by controlling the combustion process, using ceramics, building the
most efficient engines. They might not be the most powerfull, so I'll just build
them bigger oe spinn them faster until I have the power I want. How about a twin
turbo 502 with 15 lbs boost????. Has anyone ever heard a 355 (400 block w/ 327
crank) at 11k RPM? It ran away from my 482...

PS detonation is not a problem over 3000 rpm (more flames).

Just my $0.02   Tom
