To the guy holding the temp gun directly at the vent and testing the AC at 70 degrees....
This test is a fail for several reasons.
#1. Holding the temp gun right in the stream of the cold AC makes the reading artificially lower.
#2. Its 70 degs, but what was the humidity?
#3. When its really hot at stop lights, I sometimes rev the engine to 1200 rpm to get some better AC.
Please revise your experiment and show us a AC manifold hooked up and before and after pic with the pressures.:dance:
