Horton fan vs Electric?

[RSchwarzli]

Hey guys, I am looking for additional cooling for the crew so I have been looking at both electric and the Horton style fan setups in addition to a rebuilt rad.



My question is for heavy pulling (18-22k lbs), is the Horton setup better, or is the electric fans a better set up? Any thoughts? Anyone have real like data on both?



Thanks,



Robert

My experience with electrics is that they are great if your NOT pulling heavy loads as they don't move enough air. I ran one on my V8 Dodge for years but would take it off and put the stock one back on for the summer. Horton no longer makes the fan blades for the Dodge so you would have to have one made. I am going to run a Horton on my crew. I have one that I took off a wreck so I will have to get a blade made ( I have the damaged one for a sample) and then make my own wiring harness. BTW when the Horton kicks in you can really hear it. Shadrach

Oh yah. If it helps, compleate horton setups with blade can still be purchased from a place in Arizona. The only thing not 100% is the wiring harness. That is a partial buy and partial do it yourself as it was explained to me.

I have one here along with a Warner (Cummins unit) but have no idea as to how I will connect that thing to the engine (block or head) I'd need a casting as the ones on the school bus engines are mounted down low on the block, unlike ours, on the cyl head.



The clutch new is 800. 00 then one requires the hub, which I ain't got.

Do you have their contact info? Maybe I can get a fan from them instead of having one custom made. Shadrach

Try these people drivetrain.com discount automotive and truck parts On the left side of the page scroll down to Dodge and it will take to an electric fan that will move some serious air -spendy but cheaper than the Horton. BTW my Horton does an excellant job in all conditions.

Shadrach,



The place Horton told me to call was Turbo Auto Diesel at 602-272-5311. Was told clutch $474, blade $273 and partial wirring harness $78. Hope that helps.



As for the Horton setup, is that the preffered meathod then? Does anyone know how much CFM it moves? Does it have any advanteges over the stock fan?



Thanks!

I had two electric fans that moved over 5000 CFM..... or so it was advertized. It didn't move enough air. Back to stock set up. I would be curious to know how much air is moved with the stock unit, Horton or the like, and the electric that Bob is talking about.

Stock fan is rated around 7500-8000 CFM, IIRC. The highest flowing electric setup I have seen is for the DMaxes and that was only 6000 CFM.

 

[Shadrach]

According to Flex-a-lite p/n 262 ( 94-02 Dodge CTD ) pulls 5500 cfm but is Not recommended for over 18,000 lbs. Robert what rad and CAC to you have in your 93 crew? I don't want cooling/heating problems on my crew thats why I am going to use a larger rad and CAC. Shadrach

Can someone varify that?

Shadrach,



For rad, it will be a aluminum 4 core unit. It will be a little bit thicker than stock. As for intercooler, I have not determined yet if it is worth going to a aftermarket unit, or if I will just install a 2nd gen unit. Either way, I do not believe it will be the stock one! Oo. For more info on the rad, see Aluminumradiators.com / Aluminum radiators for Hotrods, Muscle Cars & Trucks or call and speak with Bill. He has done MANY 1st gen rads!



As for the fans, I guess by CFM volume, electrics are out of the question. Now the only question is, how much more efficient is a Horton over stock? Does it flow more cfm? Is it worth the extra dollars?

As far as the Horton fan it runs just like your A/C - it's electric - so when your rpms increase so does the fan speed. I turn mine on manually when I am in traffic and have the A/C on and in temps up to 105 in stop and go traffic the temp will not go over 180 and usually stays at about 175. Towing at 65 mph - total weight trailer & truck 15,000 lbs - in 95 degree weather engine temp stays at a steady 180. Those are the only times I run it so I am getting the benifit of no fan 95% of the time. I can't tell you how much air it moves but it does move some serious air - much more than the stock fan. Another advantage is you can turn it on manually before you get to a hill. When it's running it sounds like a big rig. On a dyno between runs it will drop the coolant temp 30 to 40 degrees in less than a minute.



Hope this helps.

My rad is similar to yours but a lot heavier as it is not aluminum. For an air cooler I was thinking of this one-
