So I've been thinking about different ways to get air up to the radiator in the subaru conversion where the radiator is in the engine bay. The standard way to do it is to have a couple of normal radiator fans sucking air from beneath the car.
Here's another idea... What if I constructed an array of ducted fans as in the diagram below. Basically they would force air up the shroud and through the radiator. One advantage to this is that it would take advantage of the entire surface of the radiator, rather than a round section that a fan would push through. Something I'm trying to figure out is the conversion between thrust and CFM of air moved. Most of these fans are for hobby RC airplanes and are rated in ounces of thrust, rather than moved volume of air. -Tony Attached image(s) |

The stock air-cooled setup pulls the cool air from above and exits below... Isn't part of the reason because of the difference in air pressure between the underside and top of car - especially at speed? In other words, by trying to pull cold air from below and exit at top, are you fighting the natural air pressure? Wouldn't the air flow considerably easier from top to bottom?
