The pressure(s) are 100% dependent on temperature & altitude..also the amount of refrigerant that you put into the system..

I would think that high pressure should be around 300-350 at 2500rpm in neutral..& low pressure less than 35 at the same time...

Aux fans should be on LOW speed at 230psi....

R134a charge should be 65-70% of the R12 capacity
