Drag limit

Does weather like temp,air pressure,or whatever affect the amount of drag is put on the car at top speed?

Absolutely.

I believe the equation is:

Drag = Cd*FrontalArea*Density*Velocity-squared

Density being dependent upon the factors you listed. However, it takes alot to change air density significantly, so it's not a huge effect.

I bet it is different depending on how high or below you are from the sea level(air pressure).

Faster....

Sure, you'll go faster where we are, at 3,000 ft, but remember you'll be getting less air = less horsepower in an NA car, so the overall effect is actually slower.
