With the datalogit software are you able to adjust the turn on temperatures of the 2 fans in a Third Gen separately. Meaning can one fan be set to turn on at one temp and the other kick in at a higher temperature. IF this is not possible, I will put in a mechanical switch in to operate one of the fans. It will be installed in my water pump housing and my motor in out right now so this is a good time to put in the switch. I will be running 2 Spal 11" fans with a combined CFM of 2460. This is way over kill except for 100 degree days is stopped traffic with my AC on. I do like to be comfortable
I will be placing an order soon for the software but I have to figure out how much I am going to spend on engine parts first. So if you are asking yourselves " Why doesn't he just read the frigin instruction manual and not ask such stupid questions ", I don't have the instructions yet and never had my 3rd Gen running for more than 40 miles with the stock turbos and cooling system. I am single now and have a 27" X 15" Griffin radiator. I want to tie into the stock harness if possible

id run both at the same time. Reason being if you dont, that one fan might suck air back thru the radiator (from the side thats not on) and just have that hot air go around and around (bad for cooling!). I have seen this happen with fans for intercoolers when there is only 1 and no fan shroud. If your worried about the eletrical draw, dont be. The alternator puts out (well should be putting out) more then enuf eletricity to keep your battery and other eletrical devices nice and happy. (it does put out 100amps at 3000rpm). As for wear on the fans, they are design to run for quite a while (they are fans after all )

P.S. What happened to your stock fans?

I don't think I will pull air back in through the side of the radiator although it is a possibility that I haven't thought of. With 2460 CFM, my water temp will drop so sharply when the fans turn on that my thermostat will constantly be opening and closing during non summer months. I was planning on setting up the fans to keep the engine operating temperature between 187 an 192 degrees F.. My reserve is over 2 - ½ gallons of Evans Coolant and my intercooler / condenser / radiator are fully duckted together. When my car is moving over 20 MPH, the water temp has never scene 187 F. The one fan I was running never turned on. Ambient air temps were over 80 F. I stile have my stock fans in storage.
