Trying to figure out what fan or fans i should pick up for my swap.

I do not have AC, however the summer climate is quite toasty here in AZ. I am thinking of going with a pair of 10 or 12" fans in a push/pull setup (one fan pulling air the other pushing). As it sits, I would have the puller fan sitting on the driver side of the engine bay behind the radiator, and the pusher on the passenger side in front of the radiator.

Any thoughts or recommendations as to a good CFM I should pick up?

I think one fan with a shroud would be more than enough unless it's a turbo or something. Even then one will probably work ok.

It is a turbo (gen4 3sgte). No AC, however I do live in Arizona (120* summers).

10" doesn't line up on these new radiators like I told you the other day Tim. I'm gonna take some measurments and explore bolt-on options tomorrow, but you can still do pretty much anything if you use the zip-style hold-downs. I'd say go one big ass 16", but I don't know if it would clear the 215 manifold or not.

I have a single 10" fan on mine i dont think i could go any bigger. I have the all aluminum rad, I used the zip tie things.

what model do you have and how much-ish did they run? I just got a pair of Mishimoto pushers but if those aren't enough I wanna go all out.

if they don't have curved blades they aren't good enough.

I always thought straight blade fans move more air and the curved ones were quieter.

Too bad the fan I haven't looked up is too deep to fit behind the radiator with the turbo and exhaust manifold right there.

put it in front and run the fan so its a pusher

but then I run the risk of heating because the fan is chopping the air as I'm driving. I see the benefit of the fan, however having just that 1 fan on the front I don't think I could trust it. If somehow it could fit behind, it may work.

For the LED lights we make which produce allot of heat - for the ones with fans - we always mount the fans as "pushers" - they are much more efficient that way.

We have proven that with our thermal imaging camera.

Certainly in my older experience with my Hemi car a shroud helped tremendously as well.

Pushing air usually works better because it prevents the dead spots -- low-pressure zones in the airflow's incoming path tend to create a lot more turbulence than low-pressure zones beyond the fan. Easy way to demonstrate this is to take a fan and block the intake, then compare the noise to blocking the output. Fans work better with a consistent pressure.

The caveat to that is with radiators being both larger than the fans, and with the openings evenly distributed, the low-pressure area is evenly distributed, and with the thinness of the fins a sufficient offset from the radiator ensures the fan doesn't have to deal with separated air streams.
