Reply to "AC CONDENSER UPGRADE IDEAS??"

When I decided to make the change to R134 I replaced the condenser with a thicker unit from Pantera of Colorado. I am still using the stock fan but would like to find one that pulls more air if that is possible. The hoses were all replaced and a new rotary compressor was installed along with a R134 expansion valve. I tried the system with the original expansion valve and it didn't work as well as I had expected.

With a 90 degree outside air temperature, I have 38 degree air from the interior outlet ducts. I do have to agree that once you start going above 90 mph the air flow through the condenser is reduced and the duct outlet air temperature begins to rise. Taking the trunk liner out also seems to hurt condenser performance, but I seldom drive the car without the liner installed.

If I ever do anything to this system again, I will relocate the condenser to the front of the car and not have to worry about limited surface area or lack of air flow at high speeds. I also like the idea of eliminating the rear condenser fan and reducing the electrical load on the system.
