Finally found out the limits of the 17" Mustang GT cooling fan that has been in The Mark since the supercharger install a couple years ago. Metro Atlanta heat wave 2010 has been in the 90's+ just about every day for a couple months now, and when I drive in stop and go traffic in these temps, the car temp gauge will move beyond half way when I have the A/C on, and will recover and go back to the normal middle of the gauge position when I turn the A/C off. On the interstate at speed, the car runs normal with the A/C on with no problem.
I had Aric look the car over, and he said everything is functioning normally. He was able to recreate the symptoms in his shop, and his dyno fan cooled the car off 22 degrees while it was running idle in the shop. He figures the dyno fan is good for 45-50mph wind. So, blame it on the weather.
The car has a Ford Racing Mustang Cobra radiator (for a manual shift car = no trans cooler tanks), a Treadstone supercharger intercooler, a huge Ford truck trans cooler, and a stock Mark VIII A/C condenser all stacked in the nose of the car.
Now driving without A/C in Atlanta in the summer is like driving without a heater in the winter in Michigan. Not gonna happen
So, Aric is going to install two Spal push style fans on the radiator directly in line with the grill opening. Each fan should be good for 440 cfm (880 total cfm). We are talking about going with a Spal 16" high output pull fan replacing the Mustang GT fan. The 16" Spal fan is good for 3300 cfm. The problem with this 16" Spal fan is it needs 45 amps to run full speed. Just need to see if the electrical system can handle the additional amps. I think a stock Mark needs 30 amps to run the fan. lol I feel like a engineer on Apollo 13
The plan is to have Aric wire everything to run through the PCM and VLCM.
Here are some pictures of what it looks like before the mods, and the fans...
