ELECTRIC FANS SETUP??????????
What do you guys use and what is your opinions on the best brand and setup? How do you hook up the switches and thermostats? Also will my alternator pull all that extra power?

Re: ELECTRIC FANS SETUP?????????? (Corvettelvr73)
Well - I have a upgraded 100 AMP alternator and I'm running 3 electrical fans... I don't run them on a thermostat.. One of the fans is permanently on and the other 2 fans (Flex-a-Lite dual electric) are switchable...
The always on fan that I use is a 2950 cfm Permacool fan.. This fan was less then $100 but outperforms the twice as expensive Flex-a-Lite duals... :eek: :eek: . If I would have to decide again - I would use dual Permacool fans... For a non-radical stock engine - one Permacool fan should be enough to keep the car cool...
:cheers:

IMHO, dual SPALs are the best I've found. Much higher flow than the others, and they cool the 502 very well. I think Tom DeWitt sells them.

1) pull less amps (even if running 2 of them)
2) Flow much more air (2950 for the puller and 2100 for the pusher = 5050 cfm) :eek:
3) pay over $100 less than for the spals...
Even a single Permacool fan should be able to keep a non-radical engine cool...

I'm running a single chevy late model fan out of a Grand am, etc. Works good in Texas, but will need to step up to duals for racing.

Be careful on what fans you buy. There's a guy that had his fan setup start a fire in his engine compartment. I can't remember what brand he had but I KNOW it wasn't Spal. Do a search to find the thread I'm talkin bout. That's the main reason I went with the Spal setup from Dewitt, quality. :cheers:

If you run 2 Permacool 16" fans - you will ...
1) pull less amps (even if running 2 of them)
2) Flow much more air (2950 for the puller and 2100 for the pusher = 5050 cfm) :eek:
3) pay over $100 less than for the spals...

Amp draw 12.5 each or 25amp when both are running.
Dewitt sells the fan only (which requires no brackets) for $277
The air flow is 2780 cfm, which is about the same as yours.
I don't understand all the hype and attention with amp draw and larger alt. I've had sound systems that pulled 25 amps. Finally, the spal dual package is rectangular and covers 90% of the core face. A single 16" fan would only cover about 50% of the core face. The dual pull fan is not an obstruction in front when driving high speeds and it also has built in flapper check valves to allow for free flow when the fans are not required.
