I upgraded my 1989 911 Carrera Cabriolet OEM AC from R12 to R134a using Griffith's Kuehl evaporator, receiver/drier, barrier hoses and added rear wheel condenser. Now my car blows 38 degrees at idle from the center vents and 35 degrees down the highway. These temps were recorded last week here in Phx AZ on a 117 degree day with 17% humidity. The OEM R12 system never blew below 60 degrees. The kit from Griffiths was very detailed and I did all the install myself and took it to my Porsche mechanic (Don Jackson Ent.) to charge. They hooked it up to their fancy Snap-on machine and 39oz and 30 minutes later it was done! I wish I had done this years ago. Anyone else have similar experiences?
