Air Box, what's that all about?

Very interesting & goes to show that rolling roads are a waste of time.

Looks like there is an error below regarding atmos temp & intake temp.

So back to the subject of the intake.
Some information I gathered in autumn of 2010, when doing a drive to Stuttgart in Germany.

The atmospheric temperature was 10 degrees.
I don't remember what is the metric for the mass of air (possibly litres per second, but I can be wrong).
Sport is on and the flap was open in all cases.

Speed | Intake temperature (C) | Mass
--------------------------------------------
60km/h 23 C n/a
150km/h 14 C 27
260km/h 6 C 44

The massive difference of the intake temperature is clear, as well as the mass (150 and 260 were with same rpm as I recall with 4th and 6th gear).

I could repeat the tests soon (I am pending a trip to Munich and Salzburg ) and get more sophisticated measurements with my updated telemetry.
I will update you in 2-3 weeks time with new values.
