Ferrari Mailing List: Re: A/C R134a pressures

Rick,

At 90F ambient temperature, the low side should be 45-55 psi, and the high
side should be 250-270 psi.  This applies only for an R134a system.

Subject: [Ferrari] A/C R134a pressures

Hello Troopers,
     What pressures should one expect for the low and high sides of a R134a
converted 308 A/C system?  I know that changes with ambient temperature too.
Your advice?
     I charged my system last weekend.  The low-side charged up to 45psi,
engine running and A/C on high, at 90+ degrees ambient.  I did not measure
the high-side pressure.
     Advice?
   
  Rick
