Turbo guys with A/C, how are you keeping it cool?
My car will run perfectly fine a/c off, but when it's hot outside and the a/c is on it runs hot as hell (235*+).
My combo is in a fox body, I have a 3" aluminum dual pass radiator w/a 3.8L Tarus fan (3700cfm@33amps). I have the stock f-body condenser in front of that, and a 4" intercooler in front of that, with a portion of that covered by a 1.5" thick trans cooler. So obviously part of my problem is just having so much stuff for the air to have to pass through. I even built air shrouding to force the air through the radiator, still no dice.
With the a/c going on a 95* day I am seeing 160* IAT's and 235* coolant temps. I am running 100% water w/1 bottle of water additive.
I am lost as to what to do now. It is def. related to the a/c. It can run 235* a/c on, within a few minutes of turning it off it'll be down to 212*.
Anything I am not thinking about that could help?

Moving the trans cooler to the back or under the car will help some, we only saw 5-10 degree changes though. Why is it running so hot without the a/c on though, my ltd(basically a fox) will run 165 degrees on a 90 degree day, 175 beating on it on the highway, and in extreme cases might get up to 200(very rare). It does have a 31x19 dual pass radiator and two spal puller fans with nothing behind them. I don't have the ac lines made yet, but the rest of the ac system is in the car.

what does it run if you never turn the a/c on? Where are you taking temp readings from? What type of guage are you using? If it's an electrical one the extra electric load from the a/c could be setting it off. I have been dealing with odd guage readings so just sharing some info I'm reading.

Here are is some other info I got.
Some other ideas might be to make sure the condenser is clean and free of debris, spray it from back to front with a hose/nozzle, same goes for the radiator. Monitor the A/C pressure on the high side and flip the a/c on at idle and see what happens, if it starts to get too high you have an airflow problem IMO. You can also verify that by spraying water on the condenser and see if the pressure starts to drop. High pressure means more heat means hot coolant temps as the air coming off that condenser is VERY warm hitting the radiator. Maybe use a temperature gun to see how hot the condenser is getting.

Do you have an air dam under the front bumper? This was necessary on a lot of cars. It allows less air to flow under your car, creating a higher pressure area in front of the radiator, which in turn forces more air through the radiator.
Can you post a pic of your cooling system setup?
