Electric fan question

[blueroo]

Would a 10" diameter, 615cfm s-blade push/pull fan be enough for my car? 170, 1v, nothing major as of now

 

[Thad]

Should, especially if with a shroud ring. How much "stop and go" driving do you do? A/C?
Above 30-40 mph enough air is rammed through rad that no fan is needed.

8) taht fan will augment your mechanical fan, but dont use it as your only fan.

 

[blueroo]

What would you suggest then?

That would be good as a pusher in front of your radiator. But, not as a puller on the engine side.

For a puller you would need something in the 2000 CFM range? I know some V8 guys who use Black Magic fans which I think are in that range.

Does one really still need a shroud with an electric fan mounted flush with the radiator? Also, I thought a pulled fan is always a more efficient setup then a pusher, so why would you desire a stronger fan if it is pulling?

This won't help you a bit, but. Pusher fans naturally block normal air flow to radiator. Pullers or stock fans need the shroud to funnel the air thru radiator instead of pulling from the sides and just circulating the engine heat. Ford Taures fans are popular also but have no idea about them fitting your application.

You want a large enough fan so that you can get rid of the parasitic one bolted to your engine.
Make sure you install a thermostat switch to the electric fan so that it will only run when needed.

The 170 doesn't have that much HP to begin with, so any way you can eliminate a power drain from the engine (engine driven fan) the better off you would be. If you have a generator on your 64, now would be a good time to switch to an alternator.

Its hard to say what is the smallest fan you could get away with but that is definitely too small. Get the biggest fan you can fit, which is probably 15 to 17 in, hopefully flowing 1700cfm or more. Get a temperature sensor to cycle the fan on and off as well. You can't go too big as long as it physically fits.

X2 Electric fans draw a lot more amps than you would think.

 

[blueroo]

Already have an alternator from a Bronco II and I have an optima battery. Most likely Ill be going with a pusher fan as I want to free up space between the engine and rad

 

[Thad]

An electric fan with an intergral ring shroud, which most are made with, are more efficient
whether pushing or pulling than one without.
The ring decreases tip loss and vortices. As a fan move air some slides outward to the tips due to centrifugal forces creating vortices and turbulance ---- lost flow.

I've run my maverick 170 successfully in various configurations.

Box stock for nearly 40 years.

With a pusher fan from an 82 Sentra as the only fan.

With no fan at all.

Running down the Tristate tollway in chicago in september at 70 MPH with a busted fan belt for 35 miles without over heating till I exitted the tollway to surface streets. I noticed a small amount of steem coming out of the hood after a few blocks. I pulled into a fast food parking lot, installed a new belt and was fine.

When the 170 is in good shape it does not take a lot to cool it.
