Clutch vs. Electric Fan

[805moparkid]

ok so i was going to mod the rad support to allow the clearance for the use of a clutch fan...

the reason being my singe 16" fan is not working...

but being i am a numbers chaser im going to ask... will the clutch fan really make that much difference at the track?

i cant afford a big expensive fan set u so im looking for a cheap alternative...

I would say an eletric fan would be better. For the simple fact that you can run them on a manual switch and coil the car down aftet runs while the car is sitting. Instead of the car running to cool off. Just my .02. Aj.

2.25 core, dual 1.25 cores...

i think i have plenty of rad even for our area just need to get good air movment...

but at the same time im really not willing to give up ET LOL:wack:

 

[RustyRatRod]

I think that would work with a single row as big as they are. There's you some more ET right there AND the clutch fan would fit. lol

yea thats an idea...

well this is what i got....

P.S. the current fan isn't centered becasue it will hit the water pump...

 

[RustyRatRod]

cool.

also make sure you've sealed off any place air can go around the radiator. the upper support and the top of the radiator, the sides if the mounting brackets aren't flush, ect.

i think your biggest problem is you race in Phoenix ;)

 

[inkjunkie]

Shroud might help......

Apparently a clutch fan will save you 7-12 up.I run records stock 2 core rad with a clutch fan with my 410 in my 66 Dart.It runs very cool.Oh no thermostat either.Alls good after 180 passes.

For my .02, I was running a clutch fan on a new Moroso water pump. My new pump's bearing pushed out at 5000 rpm's. Destroyed my very new rad and fan. Needless to say I went back to electric with my new rad.

of fun... what fan(s) are you running?

grab a 2000+ neon radiator fan those pull some serious air and can be had on the cheap

Second that dual fan with a SHROUD! any shroud would help, your fan is pulling through through less than 50% of your radiator area. If you pull the fan back (or get a dual setup from a Neon/Breeze/cloud car) you may still have clearance in the middle for the water pump hub, and will be pulling air through 100% of your radiator area. Pusher is the same bad design. Small area gets cooled.

 

[stroker_valiant]

SHROUD!! I was running the same type setup as you, meaning one 16 inch fan right on the rad. I'm sure you are aware that you are only pulling air from that one localized are, all the other rad surface is going uncooled. I did two 10 inch fans offset cause the water pump wanted the same real estate.

yea it sucks lol... do any of you know what the neon fans "core" width is??

and when i set the rad back a bit i can get a better fan set up to fit without water pump pulley issues

2000+ neon core width is about 25 1/2 inches (they have top and bottom tanks) the plastic shroud would have to be cut some but they are a great choice and can be had cheap

Go look at the electric fan on a 2006 Durango.

Less than 60 bucks from rock auto.

Could try to make a cheap shroud out of a baking sheet see if that helps. I have the same offset fan issue due to the water pump. I found this site where some guy came up with the idea. http://www.v8s10.org/forum/viewtopic.php?f=46&t=20834
