So does this mean you are making more fan kits?

If there's enough interest in my efan design I will continue making them.:thumbup:

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices

Damn it, now I need to scrape some cash up for this one!

I saw this at the NESM and its a solid design, as with any Supermod product.

Gerry was telling me he picked up 1 mpg with his Supermod eFan.

Does anyone know if there's a performance difference other than picking up 1mpg?

Many write-ups have claimed 17HP improvement from a electrical fan but my Dyno butt says realistically about 10HP.
The fuel improvement isn't were you think it is.
Since the OEM fan has to work more at idle or lower RPM's to maintain cooling.
The MPG gain is at city driving more than highway.


Here's a simple formula to justify the replacement of the mechanical fan.

For example let say the mechanical fan needs 10 HP to function.
A efan running at full speed consumes 20 amps @ 14.4v = 288 watts.
With out going in to full detail let's say for every 1 HP equals 500 watts of power, don't assume 745.7 Watts is a realist HP to watts conversion. What about mechanical loss? belt etc..
Your gasoline engine has to produce 0.6 HP to power a efan running at 20 amps @ 288 watts.

So the bottom line is a 9.4 HP gain!

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices



The point to my calculation was to demonstrate regardless if it was 1000 watts to 1 HP or 500 watts to 1 HP that there is a potential gain by doing this upgrade.

The 746 watts to 1 HP formula is if this was a perfect world and there wasn't a loss in energy.
The power plant, known as the alternator is a very inefficient and a very crude design to produce electrical power.
Since the alternator relies on variable mechanical energy rotation of the armature.
The magnetic field (EMF) collapse and energy loss in heat across the rectifiers contributes to the loss's in the power to HP conversion.

In my real world experience I have found the conversion to be about 500 to 550 watts on a GM S12 alternator.

Thanks for your input!:high5:

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices

Without revealing any trade secrets, what redesigning / value engineering are you doing? Will the controller still function the same without any compromises? Any idea of expected price range? I am also very interested! Saving my pennies and swimming in wishing wells picking up change all across the south east.

Improving the event cycling adaptation and increasing the averages to minimize spikes and transients. :shrug:

Sounds like much better improvements. Hope you are able to get the pricing down.

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices

I understand that the cost of this unit is expensive bc of parts, looks like im going to have to wait to get this one, I need it though, really kills my mpg responding to calls when that stock fan kicks in. I really feel the drag when I have the AC on too.

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices

x2. There is nothing on the market that I can find that comes close to this fan. Getting a variable speed fan and controller, almost 1.5 times more air flow potential and a lower inrush current, this fan it the way to go. Saving my money.

To help reduce the fabrication costs, Ron The Wolf has stepped up to the plate and he will be fabricating the efan frame and mounting brackets.


QUESTION: Would you pay $400 ~ $450 for this custom, Plug In Play efan?

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices

correct me if im wrong but its what 350-375 to do a really nice efan set up?...but that with figuring out everything on your own?

so yea i think 400-450 is plenty fair just becuase your making it stupid simple for us who dont do electrics

id say if you figure out how to make it $430-450 shipped for members, youll prolly sell a good amount

im sure theres plenty of people like me that when it comes to shit like this stupid simple is king

Ya you can get a Flex-A-Lite for $250 ~ $300 and a PWM controller for another $100 but you have to fabricate and wire everything yourself.

So with my efan you pay about the same, pre-wire with mounting hardware and ready to install.


Good feedback, Thanks.

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices

But you are getting a fan which is more energy efficient, can deliver more airflow across the radiator, has a lower full load amp draw and greater turn down capabilities with the supermod fan. The equivalent Flex-a-lite fan (based on airflow) is 6" wider (not sure it will fit or that it could be customized to work), draws 50% more amps at full load, can not be turned down as much as the supermod fan and costs much more for the fan itself (dual fan setup).

So HELL YEA! Still very interested. Can anyone else help in any way? Need any money in advance to assist with development?

Here's a video with sound of the efan in operation.




You can hear the Pulse Width Modulated controller making a chadder sound to reduce the inrush current to the normal current draw.
This fan covers more than 98% of the radiator. I had to make a small waste gate cut out at the bottom of the fan incase water or any debree got in there.

re: SuperModulation EFAN Model SFAN4500 Electric Cooling Fan Kit, Installation & Prices

Did not see this anywhere in this thread but will your controller have a manual override kill switch and AC relays? Kill switch would be used to stop the fan when crossing potentially deep water. Thoughts?

Yes! my controller ties in to the key points in to your electrical system and has both overrides to turn it OFF or ON options.
This will be an option for a pre-wired harness and a under the dash switch when purchasing the efan.

well keep you posted. feel free to ask more questions. and trust we are working on this round the clock(well really only about 30 minutes a day) to serve our great members. lol

hahahahaha!

Another question on the controller that I am sure supermod :bow: :ss: :bow2: has covered is delaying energizing the fan at engine startup to keep that extra load off the alternator and delaying turning the off after the engine stops for additional cooling. With the delayed off, will it be via time delay (adjustable?) or until a certain temp is reached (adjustable?) or other?
