| I have been testing my electric fan setup in the Florida summer heat - here are some results Mod list drilled water jackets Stock 185 Deg Thermostat Koyo Radiator Primary fan - 16 inch Spal puller 2500 cfm Custom shroud Digital Temp gauge and controller A/C fan has been replaced with a 2500 CFM Spal pusher fan Running Conditions Idling Ambient temp - 98 F Fan set at 180 F Actual temp at idle - 180F to 182F Moderate driving around town under 40 Mph Ambient temp - 98 F Fan set at 180 F Actual temp - 182F to 187F Hard Driving - several pulls 0 - 120mph Ambient temp - 96 F Fan set at 180 F Actual temp - 185F to 189F drops fast to 185 when you get off the gas Highway driving 10 minutes at 80 - 90 mph Ambient temp - 96 F Fan set at 180 F Actual temp - 185F to 187F brief spikes to 189 when passing Will be testing with A/C later today once i get the A/C recharged. With the secondary fan firing up i don't think it will result in a huge temp increase. I think it might help to use a 170 or 175 Deg thermostat since i can actually get the car to idle and hold steady at 175 F if i reduce the fan starting point that low. Harry
