What should the air temp be, at the vent, after the A/C has been on the MAX setting for 20 minutes, on a day where the outside air temp is 83F?
The car is a 1996 993C4.
Thank you in advance

I hope you speak Celsius. Pic below was from this article.

Thank you very helpful!
Is the y axis cabin temp 6C (43F) to 11C (52F) at an outside temp, x axis, of 80F (26.6C)?

X axis is outside temp, and Y axis is temp in the center vents. The Repair Manual says windows up, set to Max cooling with fresh-air blower to stage 4. Then it says these temps "must be reached after approx. 10 mins. operation time at a speed of 2,000 rpm with the compressor switched on." I'm not sure what that means -- are you supposed to sit in the car with your foot on the throttle for 10 mins at 2,000 rpm? Seems weird.
