Cooling!!! Single 15" 2800 cfm fan enough? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Getting rid of the stock clutch/fan. I have a SINGLE Flex-a-lite 15" fan that PULLS 2800 cfm.

Will this single fan, placed in the center of my radiator be sufficient for hard driving and track days in 100 degree weather?? Also, how would this compare to the altima fan upgrade? I have both the altima fans and this single fan.... What to use!!!

That's a serious fan... 2800 cfm... whooo.

I run a single 12" right now (it sucks ass) but have made a shroud out of aluminum flashing (absolutely neccessary when running a single fan in the middle of your radiator) and have some ducting I made as well - it works and keeps the car relatively cool (between 180* and 200*) most of the time, but the car gets hot if I run up a mountain at speed/etc. I've got a permacool 15" lookin at me here, but I haven't installed it yet.

So yeah, I think you'll be good if you make a shroud for it. PM me if you need any tips.

Why not just get a ford taurus fan, and a make a nice shroud? From what I gather it flows roughly 3500-4500cfm, and its cheaper.

I'd be very impressed to see stats showing a taurus fan to PULL 2800cfm.

Also keep in mind that i HAVE both the above set-ups, and am trying to decide which to run on which car.

Yeah, I havent seen any charts or official details on what it flows... Ive been looking. I do know that I had a 14" no name fan, and my taurus fan outflows it on low speed. High speed feels like its almost double what low speed provides. My cars been going in 100 degree heat all summer without ever needing to touch the highspeed setting yet, and Im still using a trimmed taurus shroud.

I use a one of those flexalite black magic fan on mine.. you feel the air when you put your foot outside the drivers door.
