Enviromental conditions ?

[Gelf]

Low temps are good

High humidity is good - with out water injection

What are atmospheric pressure ? I know you need to have your cold air intake faced in to a high pressure area in the front spoiler.

I would assume the high pressures on hot summers days with blue skys are good, but bad for temps and humity ?

The flip side, rainy winters days with low pressures are bad, but good for temps and humidity ?

Ideally, you want to run your car in a country with cold dry winters. Therare almost no water vapour in the air, all you breath in is oxygen rich air.

It also helps if the place is a 10km below sea level.

All else being equal engine power varies directly with the air pressure, ie high barometer = higher power output.

Here at high altitude it is common for our outside air pressure to be 23.41 inHg, (about 11.5 psi) so our power output for NA engines is down to about 78% of normal.

Air pressure is good --- Like Richard says it would be good to race in a South African Gold mine except for the high temps.
