Q: A/C low line pressure #s?

[Tom.Murphy@xxxxxxxxxx]

Hello BMW Experts!       I may be getting near to having a real working A/C
unit again!  I am getting some pretty cool air (~ 55 degrees, driving), but
don't know the correct pressure which would optimize the system.  The car
is an '87 325is, with an aftermarket Seltec compressor.
     My low pressure line is at ~ 35-40 lb. at idle.  When the engine is
revved, the pressure goes down to ~ 26-28 lb.  At what RPM should I be
measuring the pressure, and how many lbs should it then be?
     I'll give a more complete write-up when the job is actually done.

                              TIA! Murf  '87 325is
