At the 6 minute point of the video, the vent temperature shows 3.3 deg C, that is 37.9F, a few degrees above freezing. The outside temperature gauge is showing 34C which is 93F.
Can the system run for long at idle? I noticed when you pulled over that the voltage dropped from like 13.4 to 11.9volts pretty quickly, then stabilized around 12.1. Seems as though the alternator isn't really generating significant current at idle, so I'm wondering if the a/c will get ahead of the car and continue to drag that voltage down or not unless you're moving.
Hmmm ....works better in traffic, that certainly is a plus.
so i’m considering getting one of these for my ‘79. but, i’m confused. shouldn’t the vent temp be much cooler than the cabin temp after 6 minutes?

+1 .. These guys are GOOD ! ... My '98 Carrera C2S (993) has the Classic Retrofit's 175 amp alternator update. .
excuse me sir. Does 1974 porsche have air conditioning system at first or we need to customize by installing them manually?

It looks to battery voltage to run. It's not an issue in use 👍🏻
Do you have the upgraded alternator on this video?
Yes, this car has our 175A unit.
How many amps are required to run this unit?
35 - 75A Depending on ambient conditions, cooling demand and ECU settings. Our ECU incorporates an adaptive control strategy for power management.
