Help with electric fan

[JoeJoe44]

Im thinking about putting a electric fan in my 200 and i was wondering what the CFM needed to be. Does anyone know?

8) if you are going to replace the mechanical fan completely you want at least 2500cfm of air flow across the radiator. if you are supplementing the mechanical fan, then you can go as low as 1000cfm with no problem.
