It tempting to look a power alone, but there's more. On another forum the pro's
talk about the need to run two sets of plugs, one set for warm up and one set
to run, what a pain. During warm up the engine is cold and is running outside of
the intended RPM range, the relates to poor fuel vaporization and incomplete combustion
requiring a hotter "warm up plug" . What can we do to improve the combustion
characteristics at low RPM to eliminate the need for two sets of plugs?

As for WOT power I believe the benefits come when the engine requires reduced
ignition advance, generating reduced cylinder pressure before TDC and yet a
higher percentage of the charge burned early in the power stroke.
