edited.....another member asked the question a split second before I did

 

If they don't both come on or they are only at 60%, I would make it to where when I have the A/C on, which is always, they would both be on at 100%. I am all about being as cool as possible here in Austin, Texas! We need all the help we can get on most summer, and even some winter, days!

 

I believe they both come on at 60% with ac on. I am not sure I could get them to come on 100% for the AC. but that is a good idea I will have to look into that. thanks.

 

Those look good. Where did you get them? I'm considering getting efans for my rig. Thanks for the informative posts and pics.

 

So give us the bad news......how much $$$ are we talking for the kit?

 

got them from summitraceing.com for 400 bucks. found them at a few places but never found them any cheaper. I think they are sold on ebay from time to time but I didn't find any.

 

how difficult was the install, anyone got the install directions they can post?

 

That’s about the same price as the ones Troyer sells. I wonder how they compare because that’s going to be my next mod.

 

DrPaul84, I'm not sure if this link will work or not, but if it doesn't, go to Summits web page and look up FLX-270. You'll find the install instructions there in a PDF file.

I am sure the ones that troyer sells are good but I did do a little comparison shopping when I was trying to deside. the few things I liked better about the flex-a-lite. is as fallows.
flexalite 270 efans versus troyer efans
1. 5500 cfm rateing versus 5000 cfm rating
2. fan shroud built into fans pulling air through whole radiator versus two fans sealed up against the radiator. pulling ait only through the aria in font of each fan.
3. lower startup amperage.
4 fans at start up run both fans but only at 60 percent, air through whole radiator versus one fan comeing on cooling only a small part of the radiator.

dont get me wrong I am not trying to knock troyer's fans I have heard alot of good things about his fans. but my research led me to believe the flex-a-lite fans were better. and sense I tow sometimes I wanted I got the best possible electric cooling out there.

 

ok I have put a few miles on these new efans and thought I would let you know my experience with them so far. well the but dyno dosn't say alot of hp gain maybe 8-10 hp. about the same as when added my magnaflow exhaust. as far as the performance the fans cool my ac bettter than the stock fan did in city driveing. the only negative thing I have noticed so far is that when I got the ac blowing full blast at a light idleing at 550 rpm the fans draw enough juice to slow my inside ac fans down considerably. as soon as I step on the gas and get the rpms up arround 750 rpm they are blowing full speed again. I think there would be issues if I had the headlights on and the ac blowing full blast. so either I need to get my idle increased to 750 or I need to get a smaller pully for my alternator or I need a bigger alternator. I am thinking of looking into the smaller pully as increasing the idle rpms will hurt my gas mileage especially sense most of my driveing is in city. stop and go. any one know a good place to find such a thing.

 

Bigger alternator won't help. I had a similar issue with my '99 Ranger with an e-fan and underdrive pulley. Upgraded to a 140-amp alt, no improvement. Went with a smaller pulley for the alternator, and problem was solved.

 

ok I did some searching and didn't find anyone selling overdrive pulleys for our trucks. you would think if one knew what diameter a pulley they wanted they could find one pretty easy. I measured my stock pulley it is 2 3/8 inches diameter. I figure I need to find something arround a 2 inch pulley for my alternator. can someone tell me where I can find these. I am not haveing much luck finding them on the net.

 

Nice install and good info, thanks. But God help you if RP sees that filthy engine compartment!

 

my only complaint with efans are the hot air the a/c blows. which really sucks, but once it gets kicking the a/c blows cold as ever
