My best effort would be — suck air out of the front wheel wells [to smooth flow down the sides] and pump it mechanically into the stagnation point so the heated air energizes the airflow over the windshield. Close?

They went to CNR Radiators to get these fabricated and manufactured, and then CNR took the design and told all the other NASCAR teams about it, so they built them for the other NASCAR teams so there’s no advantage there. But we had an advantage for a race or two.

Like this.

We turned the fan blades around and put them in a cowled duct, which you’re allowed to do, and blew the air through the radiator out the front. So instead of allowing air through the radiator from the front of the car into the engine bay, we forced the air out of the engine bay, drawn through the wheel houses, and also filled in the boundary layer over the body surfaces, cutting down drag.

The problem they ran into was suspected to be belt slippage. At speeds way above those experienced by an Ecomodder. He suggested a cog belt ,similar to a blower or dry sump oil pump as a potential ****ion. He was forbidden to do further any testing by Nascar, thank you Mole.
Hope this helps
