Hmm...I'd have thought in a PFI car, the concerns would be more of thermal 
expansion and not atomization since the FI's are really spraying at an open 
intake valve? I can see your point on a TBI or Carb'd car however. I mean, I 
know an engine runs more efficiently at high temps, (I remember an article 
where Smokey Yunik got 400+hp our of a Pont 2.5 and it was ultimatly a zero 
emissions engine (like 95% efficient) Cuz it ran hot, and used the heat to 
preatomize the fuel etc. Was pretty neat article. Was in an old HotRod or 
that type of mag.) But'd make more POWER at low temps, or maybe I should 
reiterate, at low CHARGE temps.
