A/C static pressure
What should the static pressure be for a r-12 stock system in an 89 camaro. I have 75 psi engine runing a/c off. I think this might be too high.

It depends on the ambient temperature. It will vary from the low 20's in freezing weather, to over 100psi in 90-100 degree weather.
75 is not too high.
