Engine cooling fans

[shiftpro]

Holy crap. What are you running for fans?

I would guess he's running a proper system imo. My one ton 496 project will be running two Spal 16" fans... one is enough but for redundancy and idling
up hills slowly and in the hot of summer, two is better. They draw something around 24 amps each when they kick in. Now my Dakota digital fan controller
will not turn on both fans at the same moment, I can program it to activate each fan independently at whatever temp I set it to.

Nothing wrong with going the cheap route obviously, but when the going gets tough, the tough like to keep their cool.
If I was tooling around town with my BB I would try cheapo Windstar fans but where I intend on going I need better insurance I'll get back again.
Spal makes the best fans, period. Maybe it's overkill but that's what my needs are. I bought from these guys...

I just don't see why it would fry the average 30 amp relay, with one per fan. I've had zero trouble with my setups, using GM fans and Ford fans.

And I won't argue that Spal fans tend to move a lot of air. But factory fans tend to be engineered very well, and much quieter too.

Spal fans with curved blades are very quite compared to straight blades... I don't know if they are as quite as factory fans.

Yes I agree factory fans are well engineered... but the factories are not engineering fans for 500hp big blocks behind 6000+ lbs trucks that may find themselves crawling up mountains on 90F degree sunny days... and expected to get the humanoid passengers back home without a trailer.
Again, for overkill...

Well done. The shroud is amazing!
