Does anyone know what the high side pressure(in psi)is on a 85-325 ? Its still hot over here in L.A.!

For my 84 318i with A/C: "switching off" pressure (set value for safety swtich) = 363 to 394 psi. Permissible operating pressure (I assume this means system max for safety purposes) = 499 psi.

Across expansion valve: Inlet = 199 psi / outlet = 26 psi
Above specs from my FACTORY BMW spec manual and according the the charts the above values apply to 318i and 325e Series cars (1984 year).

Bill in SF.
