"It would work better if you had a fan shroud instead of a electric fan, electric fans have a tendency to restrict air flow." ???????????
I'm using a 3500 CFM electric puller fan with shroud to cool a supercharged 500+ HP hemi engine. The constant operating temperature whether idling in traffic or on the freeway is 170*-180*. That is possible because the fan will pull up to 3500 CFM thru the radiator no matter what the engine's RPM is. If the constant operating temperature is any indication I see no evidence that the fan is restricting air flow at higher vehicle speeds.
I would agree that before you make the move to an electric fan you check out the other less expensive options, but if they don't pan out don't be afraid to take advantage of an electric fan. A side benefit is that they don't rob engine HP to perform their function. They will require a 20 amp electrical circuit.
