Best is offcourse not too hot and not too cold
I would have thought that only the humidity would have much importance...
how does the rest of the variables you mentioned effect the optimal temperature?
AFAIK you want the air as cold as possible without it being so cold that the water freezes out of the air and without causing problems with fuel atomisation (like jediali mentioned). The air basically has to be warm enough to cause the fuel to become gaseous (before ignition so at latest during the compression stroke).
just realised that compression ratio would be an important variable when considering the optimal temperature.
Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.
