Hey all- does anyone out there have electric fans installed on a late model? If so, where did you get 'em, and how hard was it to install them (have Backyard Mech. II cert and Shady Tree IIa certs). Also, has anyone ever heard of some folks just unbolting the fan from the clutch?

Seems dangerous...

Oh well. Let me know- I'm tired of that pesky fan clutch, especially in the morning (why in the hell it's ON when the truck is cool is beyond me!) (and yes, that's normal, according to Ford)

Thanks

 

HI!... I've been running twin 16" electric fans on my truck now for about 3.5 years.No problems yet and my truck actually runs cooler with the electric fans. I designed my own kit that many people and company's have copied now. It consists of two 16" DERALE fans and two PERMA-COOL thermo sensors to engage them at certain temps. This set-up has been proven to give you up to 17RWH.P. Here's a few pics. :

I was wondering how much your fan system costs. just looking for a estimated figure. Thanks

 

HI!... Call MIKE TROYER at PERFORMANCE PRODUCTS INC. He's know as the "SUPERCHIP's DISTRIBUTOR" in the computer chip's section. His kit is very similar to mine. You can contact him at 1- (540) 862-9515. Tell him that NEAL "THE H.P FREAK" sent you to him. He'll treat you right.

 

I've always wanted to see the proof. Everybody claims it, but I've yet to see dynos on a real world application. I can imagine the gains on a 8,000 RPM engine are more significant and this is likely where the "up to" comes from.

Having said this, I have an electric fan setup on my pre-97 truck. I too didn't like the clutch setup, after my new water pump flew apart throwing the fan/clutch into the radiator and shroud. The $380 replacement check from the manufacturer is in the mail. The HP gains are slightly noticable, but minimal. Idle is much smoother and the truck is quieter. For the money, the HP gains from electric fans are expensive from most aftermarket setups.

Here is my setup:

HI!... spaceman12321 : If you go over to "WORLD" you will see TOM IN TACOMA's dyno results. He gained 17RWH.P with a electric fan set-up. The twin fan set-up is WAY superior than the larger single fan set-up. If the single fan set-up fails you are screwed! If one of the twin fans dies, you still have the other one for a back up. The DERALE 16" fan is rated at 2200CFM so two would equal 4400cfm. The gains were VERY noticable on my truck. I added twin electric fans, headers, and power pulleys and dropped off almost a full second off my 1/4 mile times. So they do work for freeing up H.P.

 

Neal, when you put on your JBA headers, did you then goto a true dual Flowmaster setup, or did you already have that or something else on. I want to get JBA headers for my truck, but at the moment I cannot replace my entire exhaust system. I currently have a flowmaster 40 series 2 1/4" SI/SO muffler,, the rear cat removed, and the front cat / Y-pipe still there. Should the headers still give me a noticeable increas in performance with this restrictive exhaust. I am going to go all Maganflow, but I am lacking the $$ at the current time. Christmas is coming though

Oh yeah, removing the rear cat doesnt mess up anything, because the O2 sensor is before both cats. Thanks for the help.

 

I've seen a few dynos showing decent gains, but I've also seen information that shows half the dynos aren't telling the real story.

One of my local clients has been involved in stock car racing for years, both as a driver and a crew chief. He's bumped heads with some of the big boys, and has been around the game for a while.

He had some interesting data he got from another driver when he was contemplating electrics on the race car. They had done a before and after with the electrics. I don't remember the exact gains, but it was in the neighborhood of 18 HP. Remember this is a clutchless fan in a high revving application. BUT... this was with no flow over the radiator and the fan not running. They found that the natrual airflow over the radiator accounts for a great reduction in drag with a regular fan.

With some more digging, he showed me an article from one of the NASCAR mags stating that standard fans on average only robbed a car of 3-4 HP. Of course we aren't blasting around at 200 mph, but we do have a much larger air opening in front of the radiator as well. Measure a truck radiator and figure air flow at even say, 30 mph.

With some more experimenting on a street car, he found that the advantage to electrics wasn't that great at actual road speeds, but of course remained at lower speeds.

Long story short.. the regular fan only moves static air at a stop, and when moving is helping the air flow rather than creating it. Common sense dictates that as vehicle speed increases, the fan drag will decrease. They proved this in a shop with a couple of big shop fans...

 

I may be talking over my head here but by removing something big and heavy off of your motor(clutch fan assembly) you're creating less friction which inturn creates more horsepower at all rpms. I think it is that simple: I put the electric fan assembly on my truck and it feels like I removed a plow or something like that off of the front of my truck. And yes Mike and Anita are great people to work with!!!!!!!!!!!!! I've gotten most of my mods from them.

Just my .02 cents

HI!... As you guys know I'm not REALLY into DYNO #'s. Half the dyno's out there are not even close to giving you, your "ACTUAL" H.P RATING. I've found the best way to test if a mod has worked or not is to take it to the dragstrip. If your times got reduced in a controlled enviroment then the mod incresed H.P/TORQUE. If it did'nt, but actually made you go slower (like the POWERAID spacer!!!!) then you know it did'nt work. All I know is that the addition of electric fans on my truck made it go faster in the 1/4 mile and in everyday driving. That's ALL the proof I need.

 

I have 305 70 R 16s on mine. With the electric fans I can chirp them in 1st gear when I stomp on it. This is when the engine is cold. I could not do that before installing the electric fans.

hey JMC what kind of fan set up do you have?

 

TN,

I have the one that Performance Products Inc (PPI) sells. Check with Mike Troyer the Super Chips Distributor.

Regards

JMC

 

Neal,

Is yours a push or pull setup?

Thanks

 

HI!... LEANCUT : My fan set-up is a puller style. My set-up is the same as PPI's. Their kit is based after mine. They are almost identical except I choose to use the PERMA-COOL electonic fan controllers.
