Thread: Lowest Profile highest CFM 16" electric fan?

Tweet

I just installed this from Summit-
FLX-180 Flex-a-lite Black Magic Xtreme Series Electric Fans
Electric Fan, S-Blade, Single, 16 in. Diameter, Puller, 3,300 cfm, Black, Nylon.
3 1/2 thick, 309 dollars...I also matched it with a triple binary A/C switch,so it automaticly comes on with the air or the water temp rise...My radiator was 17x17 on the fins and the fan housing is 22x17, so it goes even with the bottom tank, the shroud fits great. I ran it after installing to check operation, It'll suck the chrome off a trailer hitch!

We use mostly fans from the early Vipers

Have any idea how much CFM they pull? Before and after it passes through the radiator? I did a search to see what I could find on them on the net. Not coming up with much. How much horsepower are you running?

Thanks,

Thanks everyone. I'm looking at the Cooling components set-up. I worry a little whether the 2500 CFM will be enough. I'll never have over 500 hp on the LS1 and most likely I'll just leave it alone as is. I'm going to have to move firewall back so I will be getting a little more room with that move but not much. Maybe I should recess the middle part of the firewall even more to set the engine back. I've seen a couple done this way and should still allow access to all the engine vitals for repairs at a later date.

The low profile, offset motor, fan that was mentioned may be my only alternative. I've seen that one somewhere. Do you have a link for it? I'd like to see how much airflow it produces.

Does anyone have experience with the newer model Mustang fans? CFM wise? I think they are 17 or 18" as well but instead of a huge shroud like the Mark 8's have, it has its own mounting set-up like these retrofit fans that I'm looking at. Wish I could have made the Mark 8 work.

I'll check into this one as well. If it will suck the chrome off a hitch and fit it may be an option.

I use a spal 16" rated at 2360 cfm on a ProStreet 55 Chevy that has close to 600 hp & it runs right on the Tstat, even in traffic in summer.
I use the same fan on my Deuce w/ 430 hp.
I think the key is buying the most efficient radiator you can afford- not a fan w/mega cfm.
I'd be looking at an aluminum rad like those from PRC. You only need the fan during slow driving & idling. At freeway speed, there should already be enough air moving through radiator to keep things cool.
I have several friends w/blown motors in Deuces that have close to 800 hp. They use an aluminum rad & a Spal fan w/ no heating issues.
