Great support on the part of the GTM team. Nonetheless, I can't help but file this as yet another potential cryptic issue related to the FI build. I hope you do get your issue resolved in a prompt fashion LAFittez.

Even so, I still don't get oil temps above 220, even on hot days in traffic. |

Have any of you guys checked the condition of the condenser coils to make sure that they are clean, there may be dirt on them causing a bad heat exchange, it does not take a lot of dirt to mess up an AC condenser from working to max capacity on a very hot and humid day.
I would also check the intercooler to make sure that it is clean as well. Oil temps and high water temps in the car have no effect on the A/C system unless the cars ECU turns off the AC compressor as a way of stoping the heat transfer from the condenser to affect the temp of the air going into the rad.

I just picked my vehicle up from the dealer regarding this problem and saw no ill issues. On the hottest of days in stop and go traffic, it will shut down and blow hot air to preserve its self was the explanation I received. I have a 72 row oil cooler on the front of my car so I'm sure it does impede flow to the compressor and condenser. I also have ceramic coated long tube headers with no heat shield that makes the engine bay pretty toasty. It could be the same reason with supercharged and turbocharged motors having inter coolers reducing airflow. Maybe some upgraded fans on the radiator and some ducted air flow could alleviate this problem.

hi guys can anyone post their expereince in hot states above 110f regarding the low side and high side ac pressure results ? i am limited at the time being for the high side pressure gauge and most shops around me only can see the low side which is approx 32 to 35 psi , but the ac still gets hot in stop go traffic . so before i take action with bigger than fans , i am doing sams advise ac 101 , i have a feeling the high side is either too high or too low , or the 32 psi low side is also too low for our 130f weather or gets too high when the compressor kicks in .
all your help is appreciated brand new 2012 twinturbo 370z nismo , approx 40's row oil cooler ,csf radiator , distilled water with water wetter , coolent temp is either half exactly or one dot below , oil temps is usually 210 to 220 in our 130+f weather |

I don't have experience with R-134a systems in ambient temperatures that hot, but I do have experience with R-134a systems in general. It wouldn't surprise me a bit to see high side pressures of 300-350 in 130 degree ambient temperatures. Low side under those conditions would probably be in the neighborhood of 40-50.
A/C getting hot in stop and go traffic sounds like it is cutting the compressor because the high side pressure is too high. If it is only in stop and go traffic, then you have insufficient airflow through your condenser, or the air you're getting into your condenser is too hot. I assume you have one or more intercoolers in front of the condenser? Where are your air filters located? Are they pulling in cool air or hot air from the engine bay? If they're getting hot air from the engine bay, the intercooler(s) are dumping that excess heat straight into the front of the condenser, and that is suboptimal to say the least. Quote:

well i have an appointment at one of shops that have the gauge for both low and high side , i sat in the car for 45 min in 120f weather infront of the house and it was cold as hell till the oil temps reached 220 and the dots are in the middle and most it reaches is one dot past middle , so i guess when i go there i should wait till it starts reaching those temps and test it , because if they test while its cold it might not be too hig or too low , its a twinturbo setup so i yes their is a big as% intercooler and the filters are on the sides behind the bumper , the solution which alot agree on and its a fact twinturbo setups,turbos,superchargers on those cars need bigger fans period , stock ones are not doing the job so spal fans will be replaced soon with high cfm and another fan behind the cooler , all will be with a thermo swtich .
thank you for ur sharing and help , finally someone shared or said something . |
