While on my trip to Washington D.C. to help my girlfriend move into her new apartment, my miata started to overheat mid day. It wasn't a bad overheat, I had my gauge rigged up to flash overheat at 220 degrees fahrenheit so we pulled over and let the car sit. The overheat scenario was with the stock replacement radiator, and both fans on with the ac on at idle or idle ish waiting for cars to pass as we were looking for street parking. We had been sitting there for maybe 10 minutes. It was just so incredibly hot outside and mid day heat in D.C. was just the breaking point for us and the car. Thankfully Payam (Psyber_Optix) was nearby and I had a radiator on reserve with him so that worked out. I had been so mentally out of it from the various misadventures with my girlfriends car and renting a trailer and navigating down some narrow D.C. streets that Payam really came to my rescue with helping me install the radiator at his house. I had to keep walking around the car and play part fetcher to prevent myself from falling asleep. Afterward he gave me a lift to my girlfriends apartment since I was too tired to drive safely.
But, you guys don't want to hear about that. You want to see some shiny parts right? Of course you do. I bought his trackspeed radiator that has his custom made brackets to mount not a 13 inch spal fun but a 14 inch spal fan that hugs right up to the fins so it draws in air straight through the fins and not from the stagnant engine bay air. These new fans require a much bigger relay and their own wiring to work. Payam already figured out the hard parts on Smurfette but essentially it is a 60 amp relay, with a 60 amp fuse connected directly to my alternator with the stock fan wiring acting as a trigger to my fan. Stock chassis wiring gets less stressed and I get full power to this fan. I am very happy I upgraded to that FD alternator when I did my engine swap.
But now, with this huge fan kicking on I need to re tune some megasquirt parameters because at idle, this fans startup can stall the car.
