The absolutely hilarious part about this? All the posts in that picture, except this one, are about guys with mechanical fans. Seems like mechanical fans aren't so foolproof either?
:rofl:
I'm not an electric fan guy. But I'll be the first to stand in line and agree with you that those fans you run are some total badass fans. I've worked on a lot of those cars before and I'm here to tell you that those fans MOVE some air.
They work great! Mechanical fans can work great too, but not for every application. Start making modifications and you run out of room really quick. And yeah, there's the free horsepower. Even with a clutch fan you're always spinning that fan, even if it's not at 100% it still takes power to drive it. And at WOT you shouldn't need the fan at all. So why run it? Why not just run it when you need it?
Plus, I can program the temperatures I want the fans to turn on and turn off at, setting the window for my engine operation at all times. And I can even run the fans after I shut the car down so it cools further instead of heat sinks.
The bottom line is you won't find mechanical fans on very many modern cars anymore, they're just not efficient.
