I've tried a few electric fans. In new mexico's winters I had to run one alone or the engine didn't warm up no matter what I did. Here in vegas, even a big one I tried would not keep it cool in traffic with the air on. my 18" flex pulls a LOT of air, too much on the higway, dragging me down. Keeps it nice and cool, though. I'm looking into another flex with a clutch, I want the power that I had not turning the fan at high speeds. Its a big load on the highway, and there is a noticable difference in power with the flex fan off and an electric fan installed. Hopefully a fan clutch will pull alot of air at idle. I guess it just depends on how hot it gets where you are. I wont go back to electric.
i am using an electric fan off an 86 buick somerset 4 cyl with a 6 cyl nova radiator on my approx 400 hp 355 in my nova, and during 100 degree heat this summer it never went over 200 degrees. if you get a good fan, mount it right ,and wire it right(relay), it will be good. this winter i am getting a thermal switch of some kind for it- now it is always on with the engine.
