Electric Fan

[crebo]

Anyone running an electric fan for additional cooling? I'm looking for one and not sure of the size that I should get. Any tips or suggestions would be nice.

I'm running dual electric fans with an allumnum rad. nice set up . got it from
Dewitt.

steelblue75,

Do you have the dimensions? That dewitt is alittle pricey isn't it?

 

[steelblue75]

Don't have dimensions off hand, once i got the old rad. and fan shroud out it
droped right in. didn't take the hood off or move the rad. support forward.
think i payed around $800.00 for the fan's and allumnum rad. By the way
this went in my 75

As far as dimensions go i'm sure it's the same as the original

I'm running a Flex-a-lite since 1999 on my 383 with no problems with a copper L82 rad, its model FLX-150

you can just see the top of it on the left side of this picture about $200 its a universal fit you will have to fab up some brackets.

Thanks bossvette,

That's a cool photo. It would be cool if you could send a bigger pic. Is it your main fan?
Does it fit really tight? How did you fab your brackets?
My car doesn't run hot hot. I plan to hook up my A/C. I know that will run up my temp.

Thanks so much.
Chris

I don't run any other fans, the kit comes complete with a thermostat switch I think I just used the brackets that came with it just modified it a little. I don,t have any other pics , but can take some later on, but they wont be as pretty since theres about 35,000 miles on it since those pics

Running only one 16 inch 2450cfm electric fan in custom aluminum shroud I made. Stock radiator and no other cooling fans. works great.

I am running a aluminum rad, not the one dedicated to the corvette but the one for say a camaro. the only difference is the angle of the outlet on the lower rad hose. A corvette is curved up and a camaro is straight. with a little crativety with the lower rad hose it works fine and is hundred cheaper.
I also run dual 16 toronado electric fans, both switch controled.
I run one low and on the inside of the drivers side and one high on the outside on the pasengers side. Both are switch/relay controled. Most of the time I run without any fan, in town one fan and in stop and go traffic both.
It keeps my blown bigblock in the 185 range all the time

Thanks guys,
I guess my only other question would be. What is the depth of the fans that you guys are using. Not sure where to place it don't have very much room between the flex fan and the radiator. It looks like I have about 4 in between the radiator and the Cooler in front of it.

I have a spacer on my flex fan about 1-1/2 I think I can go to a 1in and it will pull my fan half in half out of my shroud. I wen't from small blood to big block Anyway I think I should have got a big block shroud. With so many different mods I'm like hit or miss. I'm rambling.

I think if I can find something less than 4 in deep blowing around 2000 cfm I should be good.

remove the flex fan and pitch it in the trash use bolts instead of the studs to hold the pulley on and you will gain all the room you need

 

[curtis]

good idea gettin rid of the flex fan, however, I am no expert but you may be short of air with just 2000 cfm unless you have a much better than stock radiator to transfer the heat more efficiently. I am about 400 hp and my fan and full shroud still lets it get up to about 210 sometimes. Mine is stock radiator and fan is a puller (mounted between engine and radiator). I don't believe distance from the radiator surface is as important as completely sealing the radiator to whatever shroud, making the fan or fans pull air through the entire radiator. Make sure your air dam underneath the radiator is in good shape, as this is what brings air up to the front of the radiator at cruising speeds. Looks like Norval there is both pushing and pulling air to coo his monster.

You're right about Norval it looks like a beast. I would love to hear him fire it up.

Right now my temp stays about 200. It's not summer either. It cools very well on the while driving. I start to get into a pince when I'm in alot of stop and go. I wanted to get a electric just to help out. It's actually funny. For the past few days I can't get it over 200. Usually I could let it sit and idle for 30-40 minutes and it goes 210.

I do plan to tighten up the seals. Everyone has told me what a difference it will make. Maybe I'll get my seals before I get the electric and solve the whole equation..More than likely I'll do both..
I think if those fans of Norvals can keep that monster cool I should be pleased.

One other thing about the mechanical fan: On our stock cars, we found that if the fan blades protrude into the shroud more than about 2/3 of the blade width, the cooling is reduced. So we put spacers on it so it was at exactly 2/3 in and lowered our hard racing temps by 20 degrees (down to 210).If you are just adding a fan to the mechanical, I would be inclined to use the pusher type on the front of the radiator.

 

[crebo]

curtis,
I remember reading something about the fan in relationship to the shroud. I think my fan is all 3/4 of the way in my shroud and I'm missing a seal here and there.
I was also looking more towards a pusher. That's why I was curious about the dimensions of some of the fans that people on the forum were using. I think I have approx. 3in between the radatior and the condensor( guess that's what it is. I think derale has a dual tornado that may fit.

Chris,

Keep us posted on what you do. I would like to add a pusher for my a/c, which loses the ability to cool in stop and go traffic where you need it the most.

I'm running the Flex-a-lite Low Profile 210 dual electric puller fans. Here's the link:

The fan works great, and along with the adjustable thermostat and A/C relay, I've never gone over 210* unless I'm trying to see how long I can run at 5000+rpm.
