need help

[daves 72 dart]

i tried to fit my black magis electric fan on my dart tonite and it will not fit.the water pump sticks out to far.what i need to know is how far does the csr electric water pump stick out? the stock water pump sticks out 6".i need one that sticks out 5"to 5.5".any help would be great thanks

[daves 72 dart]

sorry its a 340

The electric ones usually aren't much shorter. However, one possibility might be an external electric pump. That's why I originally went with Davies Craig EWP pump, one of the best solutions Ive ever made. Only two 90 degree turns from the timing cover, an Y and hoses in between, and the pump floating between the lower radiator hose. We have this one in our 1571 hp engine http://www.daviescraig.com.au/Electr...5-details.aspx Together with the controller it makes an dexcellent set up for street. Don't stare at the advertised ratings, unlike with many US made pumps it actually holds true installed in the engine.

that pump pumps 1300 gal/hr.WOW. my 340 is making 525 to 550 hp.do you have picks ied like to see how its mounted?thanks

1300 gal per hour is only 21 gpm.

I just pulled the 42 gpm meziere electric off my 496. it wasn't cutting it.

I had an electric fan that did not clear, until I moved it to one side of the alum radiator.

There may be other water pump brands that may give you the clearance, or other fans that will do the job and give the clearance.

I have had Mezieres and others too, but in real life the Craig Davies pump considerably better. I think the mezieres advertised flow numbers are free flow. In street traffic with the controller, the biggest current draw I ever saw was 9 volts, and never had problems. The pump is light and small, and I had a hard time believing it would work, so I installed a volt meter between the wires. Our pump is now six years old and still going strong.

You mean amps, not volts.
Another solution would be to mount a magnum water pump in place of the LA pump. Much shorter. However, you nedd a reverse impeller because the magnum pumps run ccw.

I believe the Moroso electric pump is ~ 5.5 inches deep….just a thought.

[daves 72 dart]

i called moroso they said it is 5.95" that still to long.

[cudabob496]

how about a pusher fan, though they don't cool as well.

[cudabob496]

do you have an alum radiator?
what is dimension/depth of your fan?
if have an alum radiator, then you don't need much of a fan.
I have a small electric fan attached to a two row alum rad on my 496

With a mechanical pump, that only uses 3 to 5 hp over an electric, you can get away with a much smaller fan.

i do have a alum radiator and i bought the fan allready. i have a electric water pump and mechanical pump.i would like to run the electric water pump and fan.if i can

[cudabob496]

I have this in a 14 inch. Check out the thickness: 3.2 inches

No, I mean Volts. With the controller it's a variable speed pump that sences the water temp and runs at the speed needed to retain the desired water temp.

the fan i have is 3.5" i will check and see if 3.2"will work.thanks

[daves 72 dart]

DartGT66 can you post picks so i can see how it mounts.thanks

[cudabob496]

the Meziere electric from my 496 sticks out only 2.75 inches from the aluminum housing that it bolts up to. And actually, its only 2.25 inches except for a small knob in the center that takes it out to 2.75 inches.

[DartGT66]

Overall teh BB Meziere is not that much shorter than the stock pump, that's why I went with the external pump too, overall it's only about 2" from the block surface. This is the only pic I have where you can see the set up. Of course this is a BB, a SB set up would be more simple because the return would still be through the intake and thermostat housing, so only one Y required. http://www.kuvia.1g.fi/kuvat/Tapahtu..._31_08_962.jpg This is out old set up, the new one is pretty similar except that it's reversed, water to the heads first. The pump in the pic is in the lower right corner

i called meziere they told me the pump for the small block mopar sticks out 6.1".im looking at going with a remote water pump.thats going to cost me $550.

[cudabob496]

How about two 12 inch fans that are spaced so you have room in the middle for the water pump to protrude?

[daves 72 dart]

i have bought the black magic fan.ied like to try to use it.i can get a different fan but ied like a scroud on the fan for better cooling

[cudabob496]

sounds good. just a note, and I'm sure most know this, some shrouds can be too much, and impede air flow when you are cruising, if the fan is off. On my 496, I rarely have to turn on the fan, except at lights, cause just moving down the road puts enough air through the radiator. Having a well ventilated hood helps. Also, even though my motor is 600 hp, usually i'm only putting out around 200 when I'm cruising, so the heat load is not much then.

he has it on a 340, much easier to keep cool than a big block, much less a stroked big block
you can't just mount the fan on the outside of the radiator, and hook it up to spin opposite way?

he mentioned I thought that it would put out 550 hp. 550hp from a small block or a big block is still the same amount of heat that the radiator would need to remove. Also, a small block motor probably has a smaller radiator, so the radiator may need more air flow than a big block larger radiator. Also, most all fans sold can have the direction reversed by rerouting wires.

[bulldog426]

i would just mount the fan on the outside, and not worry about buying another waterpump... i had a stock 472 in a 68 caddy, and a stock 440 in a 76 newport before and if you didn't have everything perfect with the cooling system they would run hotter than the devil's balls real quick, although i've had hopped up small blocks with more hp than the stock big blocks that were much easier to cool, and who's to say he's running a stock smallblock radiator?? who's to say he doesn't have a heavy duty fourcore radiator or an aluminum?? from what i've seen from most 340 cars they almost always have the 4core radiators with big watertanks..

[cudabob496]

he already said it was an alum rad.
I agree try front mounted pusher fan, before spending a lot on a water pump.
elec. fans on copper brass rads usually don't cool well.
Four core copper brass rads are usually too retrictive for good air flow.
Odds are those big cars ran hot because the eng compartment is sealed well, so you get poor airflow through radiator.
But without all the facts, hard to say for sure about a lot of this stuff.
One thing for sure, any alum radiator will get you 20 degrees cooler, over a copper brass, right from the start.

[daves 72 dart]

the fan is a s-blade fan they dont work well runing them the opposite way.i have a stock and alum radiator. cudabob what facts do you need and i will post them?i should have good airflow in the engine compartment my dart has a hemi hood scoop and the fenderwells have bean cut out.thanks for the help guys im getting some good ideas.

[cudabob496]

I suppose nothing specific. I might be inclined to get a $100 summit electric fan and set it up as a pusher on the front of your radiator, and see how it works. I would think as long as the car is moving, it would not need to be on. With no shroud on the inside, you should get a lot of air flow. A Hemi scoop might limit airflow into the eng compartment a little. My hood is just vented. I just have a switch and flip on my electric when my Cuda is at a stop light. Set it up using a cheapy $5 relay from summit. I also put in a red light to come on when the temp hits 220 or so, but it never has. A red warining light for temp and low oil pressure is a must in my opinion, incase you're not paying attention, and your engine has an issue. I think an auto switch to have your fan come on at a certain temp is not necessary.

[cudabob496]

However, a pusher fan, and an electric water pump may not do it in all cases. Much better chance with a mechanical water pump in my opinion. There are high output mechanical water pumps that can be combined with a low restrictive thermostat.
