    orion, that's awesome! Looks like a factory job! Thanks for the pics, I agree with you, electric is all benefits! So that must have run you around $100 maybe?

    Nah, there is no belt change. All you are doing is unbolting the mech fan from the pulley and putting the nuts back on to secure the pulley to the water pump.

    Yep, i didn't even take the belt off, just used some washers to make up the fans gap. also the wiring kit i got has the switch that comes on at 185 and off at 170. Ive found that's too low temp, the fan was running all the time once the engine came up to temp. so i got a 200 on 185 off switch and now it's much better. the kits are the same price for ether temp.

    I was thinking about this on my way in to work this morning (Hey, it's 45 miles on I95 in some pretty heavy traffic so I had time to think).

    I'm don't mean to pee on your charcoal but I just can't imagine it making as much of a difference as y'all make it out to be.

    Assume that the electric fan motor is 1/4 HP (reasonable) and that it is twice as efficient as the mechanical (I'm being generous here). The engine is 215 HP. That works out to about 0.1% more horsepower being available to send down to the wheels. Am I missing something here?

    All that said, there are some benefits and the mod is worth doing. I'll probably do it too - someday - but we've already established my procrastination status.

    Gentlemen, do the swap and enjoy your 0.1% increase in throttle response. LOL.

    You are not peeing on my charcoal! I see the potential for increased performance; if you don't, that is your own fire you are putting out. I am about to fit bigger, heavier tires. The tires about 1% bigger and are going to rob some performance. Judging by calculations I have seen over time, your calculations are off. I have read mechanical fans can rob as much as 5 hp. Electric fans may use as much as 2 hp - but they are hardly ever on, so at most times no hp is lost. I have grown accustomed to being overgeared with my 4.77's and would like to offset the torque lost by adding these new tires as much as possible. An electric fan is cheap and easy.
