Rocket science theory vs real experience

[<dbinkley@cox.net>]

The original question was :
Two virtually identical cars (or the same car if it helps), one at sea level 
and one at 6,000' elevation.  80 degree day in both locations, exact same 
driving, exact same humidity, timing, tuning, etc.  Will one car run cooler 
than the other?
FWIW, in my Tiger, I have seen no difference in operating temps of the engine 
between sea level along the CA coast and Flagstaff, AZ at 7500' above sea level 
at similar ambient conditions, same driving and same tune.
