Update on my hi-miler Z project

[cvette98pacecar]

250+ head pressure is excessively high.
Converting discharge pressure to SCT (Saturated condensing temperature) to ambient.
R12= 168.4df or equivalent ambient temperature of 138.4df.
R134=146.3df or equivalent ambient temperature of 116.3df.

I just recharged my Riviera as I had to replace a seal, after pulling a vaccum and putting in an exact charge my DA temperature was 56df at 95df ambient. Once the interior of the car got colder the discharge air temperature dropped.
Suction pressure 42.4, Head Pressure 191.6.

Tomorrow I will test both of the Z's and get some recordings, maybe that will help.
