Myth of the electric fan

[txarkitekt]

To everyone their own... I agree with Quik about the bigger trucks using a mechanical fan since their main purpose is for heavy duty applications. But with smaller trucks and cars, electric fans do help up some engine power. Any time you can take an accessory drive off your crank, you free up power--because your crank is not using that power to try and turn that pulley. Sure, it is minimal power gains, but you see most of it with throttle response. You also see a small gain in the mpg department as well. To me, it is a worth while mod--frees up power, better mpgs, not as noisy as the mechanical fan, more room under the engine bay, etc.
I still have the stock 105 amp alt. and it works perfectly. I have a decent setero in my truck along with electric fans...and with my smaller pulleys, I usually charge at about 15 volts on the voltmeter on my dash. If someone does efans and has a decent stereo on their truck, I would recommend doing a set of underdrive pulleys to help with more power and charging the alternator a little better...
