Thread: Aluminum 406 cooling problem

Electric fan !!!!!! Theres your cooling problem. There is no way no how an electric fan is going to shift the amount of air that an engine driven fan is going to move. An electric fan is mainly used in conjunction with an engine driven fan. Granted, some ricers only use electric fans, but you have areal motor in your rod and you need a real fan. What you want to do is lift the bonnet on an earlier american car and lean over the engine (dont get caught up in it !) and get the throttle linkage and hold it at 2000 rpm, that big windmill shifts a lot of air dont it ?
I have personaly been to a few burnout compititions, and that is one of the hardest compititions on cooling systems around, the car is practically stationary and is putting out decent power, to stay cool that car is relying on its fan to get the job done. Now as an observation practically all the electric fan cars were overheating or poping there radiators, "gee I wonder why ?"
So I would seriously recomend that you put the biggest 7 blade steel fan that you can physically get in there. There has to be at least 4 to 5 inches between your pullys and radiator right ???
