After reading though all of these posts I think I am just going to go with the front mounted condenser running R134a rather than looking for ways to upgrade the existing rear condenser. My AC system has not worked in over 15 years so it seems best to just replace almost everything and start new. I will be converting to a lay down radiator soon so I will just install it then.
Does everyone run a system pressure switch? Is it needed?
I just installed a binary pressure switch on my system this year. It is easy to do and does give you both high pressure and low pressure protection. The low pressure protection was my concern because in the event of a leak, your compressor could keep running and be damaged. Your only protection without the switch in the system is yourself noticing that the duct temperatures are not cool.
I agree that R134 is easy to get and when I move the condenser to the front of the car I will be installing it instead of a blend. With the amount of hot air that flows under a Pantera, it is a wonder that the A/C does much of anything considering that is the source of air for the condenser.
