Question A/C Pressures and amounts 4 930's

HI:
Anyone know the pressures and amounts of freon....
I have looked in a Bentley book i have for a 911 (not a 930) It states.
47oz of R12
Low side 12-30 psi
High side 115-205 psi Both at 25 degrees.
Freon amounts were not listed in my "free down-loadable" 930 shop manual.

Just wondering if this is the same for a 930, 1989.

What "vent" temp should i be getting if all is well? Apparently the P-cars don't cool as well as others. So I would like to know what is good for this car.

On my Vette 42 was pretty good.
