Who has 500 horsepower with an electric fan?

I had a 16" Permicool fan mounted through the core also. I only have 350 hp, not 500, but the fan easily handled the heat, even idling around Car Craft Summer Nationals in late-July heat. The problem was that the through-the-core mounts wore a couple of holes through the core.
I replaced the 16" single with dual-11" shrouded fans off eBay when I recently replaced the radiator using Be Cool fan mounts instead of through-the-core. The shrouded dual-11's bring the temp down noticably faster than the unshrouded single-16.

7t2vette,
The single 16 inch Spal I have also been looking at. Spal has three different 16 inch fans,....slim, medium and extreme. Which fan do you run? The 16 inch Permicool I ran last pretty much did work, was rated at 2850 cfm's I think, but mounted through the core, which is something I never really liked.

"Those with single fan setups,..Could you post some installed pictures.I'd like to get this beast back together soon,....Looking at pictures showing the clearance from the spreader bar and sway bar to the fan shroud. I have a radiator core that's 2 3/4 inches thick, and need to be sure I have enough room for the fan shroud I pick?"
(from post 11)
Why do you need a shroud if you don't have a mechanical fan?

The purpose of a shroud is to allow the fan to pull air through the whole rad. so if one was running one fan it might be possible to use the factory shroud including for mounting. There was a factory C3 aux. electric fan, that mounts in the shroud, used in later years.

This forum is a great place to find things out. Over the years I've helped lots of guys too, and that's what this is all about.
When I get things together I'll post some pics.
Thanks everyone for all the help!

Thank's for checking. The mounts look like BCool mounts for the fan. My core is 2 3/4' thick. Do you think they will work?

Heres mine,a dewitts radiator and one single fan that keeps my engine at 185.dewitts radiator is 
the fan is a black magic extreme ,moves 3,300 cfm of air and comes with everything you need,thermostat ,relays,wiring ,senser,etc. made by flexalite. also the fan hardly ever runs unless im stopped in traffic and its 90 or better degrees.

New replacement stock-style radiator with a single '96 Corvette electric fan keeps my 450HP 383 stroker cool all day. Would like to add the second fan for extra cooling in the pits between rounds, but haven't gotten around to making brackets yet.
Also, the March alternator bracket mentioned above is available separately, I'm using that on my 383 as well. Very nice piece!

i love the 16 extreme spal. they say to use the extreme for drag strip applications and not so much for the street because its 3000cfm fan is probably not going to last forever being so powerful but i have been running 2 of them in separate cars for 4+ years with no problems. for a daily driver i guess the slightly less powerful 2500 spal would be the wise choice.

For the money, I think this setup is hard to beat and pretty much a perfect fit, tons of flow and 5 year warranty.

Spal fans are very high quality units, using brushless fully sealed dustproof and waterproof motors. Also, as far as I know, Spal is the only company that lists the airflow CFM of their fans under static pressure, unlike the rest that only list a no static pressure airflow CFM number. Big difference.

Looks like a cheap no name off-shore rip off of the Spal unit. Sure, it is less than half the price of the real Spal unit, but do you seriously think that EBay fan is just as good as the real Spal unit? Cheap things are cheap for a reason: They are cheap! You really do get what you pay for.

If it's a straight blade then you can probably hear it over the motor noise, probably one reason why they say for drag racing, if it were a a warmed over 350ci then it would be louder than the motor sitting at light, correct me if I am wrong but when I have mine on they are louder than my 427ci at idle

possibly motorhead. I have the curved blade so i am not sure how noisy the straight blade would be. To be honest i know spal makes both straight and curved but i did not know the extreme was available in straight and curved. My extreme can only just be heard in the car but from outside its easily noticeable to anyone. I like hearing it so i know its on.

In all honesty if the stock clutch fan didnt take up so much space, HP i would have stuck with it as thats prob the most bulletproof system of them all.
