He went on to excitedly tell me that he was able to get the vent temp under 60 (in the 50s). Remembering the mid 30s vent temps in my '74 (with a system as in the post above) and noting that we were inside his cool shop...I was underwhelmed, but thought to myself...better than nothing. I drove the car out into the heat of the day and felt the vent air turn warm almost instantly. Oh well...should have known. Might have been good enough for Germany...but not Vegas.
Back in 1983 War Bonnet Region PCA held Tech sessions, and we always got support from the factory. In 1983 Peter Schutz the big boss of Porsche AG as I remember, wanted to take a vacation and drive down Rt-66 to California from Oklahoma City. He had the factory deliver him a brand new 911 SC and after Tech was done, he set off to California down Rt-66. When he returned he called the engineers responsible for the AC system into his office. He said he had a project for them. He sent them to Oklahoma and said drive west on R-66 and when you get back report back to me. They were thrilled of course. Then they reported back to the boss. They said, sir the AC system in the 911 really is quite poor. And Peter said, yes it is, fix that!

It was too late for the Carrera and all they managed to do was improve the vent sizes by 1986 and change the fan housing. It was not until the 964 that the AC became adequate.
