Cooling question.

Will a electric fan the moves 1,250 cfm of air cool a 225 V6 with a stock 2a radiator all stuffed into a the 2A's engine compartment?

I searched and couldn't find anything definate. Space is HUGE issue here, because I have very little to work with, about 15" of mounting suface on the radiator and about 5" untill it hits the water pump pully. I ordered this one http://www.pepboys.com/product/details/8376808/00017/?quantity=1 I had a 16" flex-a-lite but it wouldn't fit.

 

With a good tight shroud.Will probably move enough air.

 

I don't have enough room for a shroud. It will most likely be about an inch or so away from the radiator.

 

It's not just about air movement. If the radiator can't pull enough heat to the surface of the tubes and to the cooling fins of the radiator fast enough a million cfm won't be enough. I've see. Where the radiator was cool too the touch because if cooling fan air flow but the engine would still run hit because of this.
Condition of the radiator and whether it is a desert or standard radiator will make a big difference. Way too many variables to be definitive. I'd try it, carefully, and have a backup plan to upgrade just in case.

I kinda figured there would be too many variables to tell for sure. I guess I'll run it and keep an eye on it and adjust as needed, or figure out something better. It's like my Boss at the gun shop tells me. "If it were easy everyone would do it". Thanks for the opinions!

 

Sorry for the lack of clarity. Fat fingers and autocorrect make for a bad combination

Well, here is my attempt at the fan mount. I'm toying around with the possibility of an oil cooler too, but that is down the road aways.







What do you all think?

 

I'd put some sheet metal between the fan shroud and the edge of the radiator to complete the shroud. This will force air to be pulled through the whole core and not allow dead airflow spots or turbulence that can hinder cooling. You want the air pulled through the whole core, not just the center.

X2 on what nick said .

 

3x but it would be a lot better if the whole unit was spaced about another inch back. Even with a plate shroud, the air flow from the edges is going to be restricted by the short spacing, but still better than nothing.

 

My electric fans work extremely well with a flat plate against the tanks. At a foot away from the front of the grill you can still feel the air flow.

 

There it is all set up, and pushing air though the radiator

 

Looking good!

That should do it.

 

Pushing???

 

Yes pushing air from the engine bay out. As opposed to pulling it on from the out side, which I think is a more effective cooling method.

 

Nope, it will be worst, the engine bay air is hot with the hood in place it's like an over, so you're pushing hot air trought radiator, cooling will be affected. Also on the road, the fan will fight the air that want to get in the radiator from the outside. Pulling is way better than pushing, and you pull cold air instead of hot air.

 

That's what I meant. These smartphone keyboards leave alot be desired. That and my thoughts are scattered in the mornings.

 

Looks great man.

Fans are way more efficient,at pulling air then pushing air.
