Hey guyz, I am thinkin bout gettin an e-fan for my truck to keep the motor cool. Does it add any additional hp, and does it really work. If it did add any how much approximately .... I LOVE THIS FORUM

 

I would guess 15 horsies and a little better mileage. They really don't turn on much and IMO very worth while. It was a good upgrade, and when it kicks on, people are like WTF? You will notice the power though.

 

That's a good response, the typical power gains run anywhere form 12-17 HP at the rear wheels depending on exact model year, and the MPG comes up a bit as well, as you are reducing parasitic losses.

One thing to keep in mind is that installing a quality e-fan kit is not for the "novice" - it should be installed by someone used to working under the hood - just FYI.

 

Mike we are going to do alot of business this summer lol thanks.... when i get the money im going to get the e-fan, af1 intake, and xcal 2. i trust you

 

How does the E-fans work? Does it take the place of the motor driven mechanical fan or is it in addition to the normal fan?

 

Takes the place of the clutch/mechanical. "Efan" = electric fans, reduces the parasitic loss created by the mechanical fan, freeing up horsepower and improving cooling & overall efficiency. Getting one for myself within the next couple of weeks.

Side note, I am debating between the Troyer efans and the Flex-A-Lite kit, anyone have any opinions on one versus's the other?

 

I opted for the flexalite fans for the integral shroud that mounts in stock location. They pull a huge 5k cfm, and have a digital controller for soft start and variable speed. They had issues with a bad fuse block for a while, but that is resolved. They replaced my fuse block and controller, no questions asked. But so would you if you had a potential lawsuit. I like the flexalite, and I like Troyer (world class tuner and F150 guru). I have no experience with his fans. However, they are Derale fans, and I have his Derale powered active tranny cooler which is T!Ts! Here is how they look:

 

Desperado, thanks for the info. Your install looks great. Tight engine compartment, in more ways than one.

 

I like my Flex #270 because of the shroud, fit and ease of installation...the #270 is direct bolt-in for our Fords.

Where did you get your flex 270?

 

Looks like he got them from Jeg's

 

Thanks gonecampin!!
