the car is moving at an average speed of 200kmh .combine this with an opening of 150x200mm and you see just how much volume is going in there: 1,65 m³/s assuming it´s an open door situation(no preesure drop across the duct)
lets see what a electric fan can move in these conditions :12V/300W EC drive 300mm diameter fan automotive is moving 2800m³/h that´s 0,78 m³/s so you need double that thats 600W 2 300mm diameter fans .....
you usually put the fan behind the radiator to reduce bloackage so the fan is working at higher ambient temps ...reducing the mass flow movement considerably...
600W /13V = 46 amps permanent current draw ....just think of the cabling needed ..
So as there are two openings (one for each Sidepod ) the 600W fans could help you to reduce the inlet opening to half size but you will ineviatbly need to supply those 600W at the Fan drive so you need a much bigger alternator ...

But ass you said before, and i fully agreed with that, its difficult/impossible for a fan to move the air mass flow needed to cool down the system without needing huge amounts of electricity, not possible for this application.
marcush. wrote:one quick and very efficient way to improve the cooling is to increase delta T of Fluid entering the radiator vs ambient temps.
So if you could raise the water temps in the engine that would help an awful lot to rise the cooling system efficiency.One of the reasons why current f1 engines run as hot as they do.
