Duel electric fans

[J-440]

  Anybody running a duel PUSHER electric fan setup?  Also was wondering how much room is available between the core support and the grill assembly.  I don't have the front end on my car installed so I am needing some specs.  I realize you can have the radiator mounts custom made and this pushes the radiator forward or rearward.  But overall, how much space is in between the core and grill?  Thanks again.

i have found the 6 or 7 blade clutch fan to be far better at cooling than any electric setup

  Well the car is already setup to run electric fans with the radiator and I need at least 2500 cfm to keep the car cool.  But my main concern is front end space since pusher fans will be mounted outside of the core.  From pictures, it looks as if there is at least a foot of space from the core to the back of the grill.  Am I close?

sounds about right , Chargers had more room than Moat Mopars

I'm running a dual Flex-a-Lite PULLER fan between my rad & engine. I had not choice due to clearance issues with the thickness of the radiator. I would have much preferred to run a clutch setup, but the clearances were too tight.
Pulls 2500cfm, and I was on the phone with Griffin to make sure it would be sufficient to cool with my rad & engine combo. They assured me it would.
The fan setup fit great with plenty of room, too. A puller fan is more efficient than a pusher, so you might want to consider one if possible.

  Alright, thanks again guys, ya'll have been a big help.

I'll be using electric fans too, hovever I'll be using a 28 inch wide rad (don't know the thickness yet). I was advised a dual electric fan setup by our mopar shop but that would be one large puller fan and one large pusher fan. So technically there will be a fan on both sides of the rad.
I might be using the painless kit to make them work.
The puller fan would be for normal use and the pusher fan would kick into action when things get really hot. Altough I have no idea how this setup will work, i'd trust them guys since they use this setup all the time in their shop.....

I'll be picking up my stuff next week maybe i'll snap some pictures if i get the stuff home.....

  Flyinlow...what's your temp when you're sitting in traffic?  Since you don't have a fan shroud, the only area of the radiator being cooled is where the fans are.  That is a lot of unused space.  But hey, if it works then you're doing good.

Temp stays right in the middle or slightly left (cooler)  180* thermostat. Fans cycle in traffic ,unless its 90* + outside.

I can turn the fans on when ever I want, So on hot days in traffic I run them continously for airflow thru the engine compartment.

The fans are staggered up/down ,so every tube in the Radiator is cooled by a tleast one fan. Mostof the tubes see both.

They dont run  above about 20mph or in cold weather.

a lot of guys in the offroad industry are pulling junkyard electric fans with shrouds off of the Ford Taurus cars and wagons. They cool the Big Block guys at crawl speeds and up some nasty stuff with no problems.

Just a thought for the folks trying to save money. Plus the parts are available if a brake down happens.

It's a Two speed fan with a temp switch.

alot of people i know have used the fan off a Lincoln (mark8?) with very good results

 talking about dual fans has anyone used this setup is it worth it?http://cgi.ebay.com/ebaymotors/3-Row-Aluminum-Radiator-Dodge-Charger-68-69-70-71-72-73_W0QQcmdZViewItemQQhashZitem45f118b64fQQitemZ300397672015QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

I dont know but honestly, I think if you want to go trough the hassle of converting from a viscous fan to electrical ones, then you schould do it right an at least built a shroud for them fans

you guys going to the aluminum radiator don't for get the thingy that keeps the bad reaction away between the aluminum and the steel, damn i wish i could remember what its called

[BigBlackDodge]

Galvanonic corrosion.

zinks?

A few days ago I saw a TV show where the "pimp-my-truck"-guy said, it is possible to increase the fuel efficiency up to 5MPG.

Does somebody has some experience with this?
Is this true?

Really? time for me to get wiser......never heard of the term. But why do modern cars use aluminum rad's with the same engine specifications?

[J-440]

  Mauve...I think it looks like an elongated brass football thingy that slips inside your upper radiator hose?  Also, some wellnuts are needed to bolt the aluminum radiator to the steel core support b/c aluminum expands and needs a little movement.  As far as better gas mileage...sounds like a ricer who convinces himself that his Folger's coffee can exhaust pipe increases hp.

I did not see any significant MPG improvement with electric fans. Better cooling ? yes.

Yeah, Pimp my truck is staffed with thermodynamic engineers...LOL

You may see some MPG improvement if you replace a large straight-drive fan with electrics, but little improvement over a clutch fan. Remember, it takes electricity to run those fans, and the alternator belt has to do the same amount of work to move the air as a fan belt would. If you want real MPG savings, get electric fans so that you can go to an electric water pump. The pump only turns at the most effective speed, which moves more water at idle than stock and doesn't overpump at high RPMs.

my charger has @ 6.5" between the core support and the front of the water pump pulley.  I stuffed a pretty huge fluidyne rad in mine with dual spal fans... the fans are mounted high on the rad and one of them had to be trimmed very slightly to fit.  gutted the spring and tower off my thermostat and put it back in (it's basically a restrictor plate now, don't run with no thermostat at all, you should have something in there) and run the fans off a sensor that turns them on at 170 and off at 140.  cool as a cucumber. never goes above 170-175. 

[dkn1997]

my car has a big block that I swapped in and a factory 22" wide core support opening.  didn't need to trim at all.

what year charger and motor do you have? i want to get a fluidyne rad for my 68 charger and 73 challenger. what is the dimensions on your radiator? are you happy with the fluidyne overall got any installed pics you could post? i'd  like to get a aluminum radiator with a clutch fan if it fits and 1 or 2 electric fans on the front with a switch for them hot days and sitting in traffic.

[dkn1997]

.  I don't think a clutch fan will work with this rad. it's really thick.  This motor had a history of runnin hot form the minute I put it in.  This rad and fan combo solved all of it.  I don't know.  I'm usually up to my ass in all the details of my car, but in this case, my friend works with a guy who used to work for evans cooling and he just took care of it for me so I'm not exactly sure of the dimensions.  I will do some measuring. 

it's a 68 charger with a 440.
