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) |

I've ruminated on a chimney-effect idea, which it looks like you may have room for. Duct the outlet so the air has to rise, and esp. if you made a crude venturi at the exhaust end, you should get a natural convection draw using no power at all. If it exhausted just aft of the rear window, you should get even more of an effect at speed, as that should be a significant low pressure area.
I have a pet theory that too many people spend too much attention to the inlet side of the radiator and ignore the outlet side. |
