The diaphragm looks great, no tears, just a little dirty, From what I can tell the spring looks to be stock, surprising clean, Spring Length = 7.0 inch Outer diameter = 2.70 inch, Number of effective coils = 5.5, Wire diameter = 0.196 inch. I ordered a RUF 0.9 bar spring. I don't trust the manual boost controller. does any have a RUF spring in their 965. if yes what's your thoughts.
I had my AC converted to A134r in May of 2017, at my local Porsche dealer and it worked really well. I think the coldest it got at the vent was 36 deg, Not bad! until I went to test it last month, just after my winter project was complete. The compressor kicked on but no cold air. I had a local Porsche shop Autobahn Porsche service in Fairfax VA recharge the system, I was not aware that the 964 C2 took 850 grams and the 965 took 1020 grams of refrigerant, I didn't think there was much of a difference between the two cars AC system. Maybe someone here can chime in and can tell us why the difference. Anyway, I did not change the dryer, It's in the plan for next year along with the expansion valve, or maybe I don't have to. Your thoughts?
The charge lasted 4 years, is that about normal ? I just got back from a drive, it was in the low 80's out and I got to use the AC and it's cold, I saw temps as low as 32deg at idle in the garage. Here are some pics. I'm proud to tell my friends that my AC is ICE cold, Not what you would normally see in air-cooled 911's ..lol
Here's my hack that should improve my AC temps. My HVAC seems to work fine. My center and side vents temperatures in the summer are in the mid 30's which is really good and everything works as it should. I had the CCU rebuilt by ECU Doctors a few years ago and other servos work as they should. I also changed both the resistors at the blowers at the rear and the heat sensor in the rear engine compartment, The 964 turbo has two blowers in the rear. The Hammer shows no issues.
It seems to me that hot air is leaking past the foam seals on the flaps and the plastic elbow that connects the suitcase in the footwell. See the foam is old and falling apart and If either one fails you have hot air mixing into the cab or into the suitcase/vents. The interesting thing is my brothers 993 blows a little bit colder and he lives in AZ. Which got me thinking why, The 993 flap uses a rubber seal in its flaps to close off the hot air from the cab sealing it completely. 100% seal. My fix is a hack, I put 993 flaps on each side of the footwell paper tubes and I close and open them manually during the summer months. Blocking the heat from entering the suitcase and the cab. This hack lowers your vent and cab temps a lot. I'm using all 993 Porsche parts and easily reversible. Your thoughts on the mod.
