Project Misguided Angel (67 Camaro)

3D printers are amazing, I only wish I brought one sooner as I keep finding more ways that I can use it.



I started focusing on improving the A/C system and decided to add a couple of Spal 6.5" pusher fans in front of the condenser. I printed some brackets to hold the fans in place utilizing the mounting tabs that are designed into the fans. The fans are a perfect fit over the condenser and helped bring my interior vent temp down between 50 and 55 degrees and it has the added benefit of providing more cooling for the supercharger heat exchanger which is just behind the condenser. The fans bolt right to the existing mounting holes on the top and bottom of the condenser. The fans require about 6.5A each so I used two 10A outputs on my BCM. Right now the firmware commands the fans to come on whenever the radiator fans come on and the radiator fans are commanded to come on whenever the A/C trinary switch is active or when the engine temp is above a certain temp. Which now has me wondering what temps I should use to turn the various fans on and off. I can literally control each fan independently and use the inputs from the trinary switch and radiator temp sensor just by changing the firmware. I just need help figuring out what engine temps are normal for this LSA engine and what temp is considered to hot. I guess I will post that question in the cooling forum.
