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.

I had a stock '88 targa (no aftermarket tint). It blew cold in the summer in Texas. There was something wrong with that system or the guy didn't know what he was doing.
