Ferrari Mailing List: A/C R134a pressures

[Rick Lindsay (rolindsay]

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
