My box of datalogging equipment from Banks showed up today. I'll be using their iDash 1.8 system to monitor ambient conditions as well as the efficiency of each turbocharger and the CAC plumbing and oil temp. That includes pressure/temperature before and after each compressor wheel and turbine wheel. I'll be running 2x of their iDash 1.8s (1x data monser and 1x super gauge) in a PPE overhead console mount with switches.
I'll be wiring the switches per James's recommendation and I'll have the switches in the "on" position to allow the signal to pass from the temp switches to the activation pin on the relays for both fans (independently wired/with independent temp switches of course). Turning the switches off will break that connection thus killing the fans if desired.
@Chevy1925, are you thinking I should go down the path of a thermostat in the lines or just send it how it is with a temp switch in the "to cooler" line of the 2020 housing? It looks like Setrab does make a M12-1.5 thermostatic switch that would thread directly into the 2020 cooler. They have them in 180f/190f/200f ratings.
The 180f is 180.6f±3.6f opening and a 165.6f±3.6f closing temp.
The 190f is 186.6f±3.6f opening and a 174.6f±3.6f closing temp.
The 200f is 200.4f±3.6f opening and a 185.4f±3.6f closing temp.
