Myth of the electric fan

[mnc2fan]

Seems like most if not all racing apps use efans to cool.

It makes sense to me giving you more power and better throttle response. Its just less the engines got to turn, even when the fan clutch isn't engaged.

I also don't see how he is saying its overstressing an alt, since.. tell me if im wrong.. most electronics connect to the battery, then the alt charges the battery. So the fan adds no, or very little extra pull on the alt. So I can kind of see where you get better response and power with efans over using the stock fan

Guess the same argument for epumps, less the engine has to turn. Just more the battery gets used thus the more the alt needs power from the engine. But still less than what the pump or fan needs directly from the engine

Ill tell you what. Next time I get dynoed, Ill do My testing and runs and then ill put the clutch fan back on and see exactly what this means for us.

Now that would be awesome actually testing to see what you gain from efans
