Because of fitment issues in my turbo integra
I need to run a push fan vs a pull.

I am using a spal thinline 12"

It is originally a pull but I switched about ground and power and it spins the opposite way as do most fans

So queations is I will get about the same cooling power running a push vs a pull right?

 

not necessarily. The blade design may not lend itself to being reversed. I personally have found on some fan designs they are NOT efficient when reversed. My suggestion would be to get a pusher fan instead, I have used mercedes fans with good results over the years. They push copious amounts of air. The issue would be, will it fit in the desired location. I avoid the cheap ones, as I feel you get what you pay for in the fan dept. However its your engine, do what you wish.

Ahh I see what you mean the deflection of the fan blades.

Good idea I suspose I will order a fan specific for push duty.

 

It's the little details like this that will make your build successful or not. Good luck.

Thanks

 

When you refer to push/pull are you referring to front mounted fan or rear mount?

Air must always travel from front of car to the engine compartment. For the sake of longevity and simplicity nearly all fans are of the pull type, mounted behind the radiator. Mounting a push fan to the front of a radiator is possible, but why would you subject the fan to damage, which will more easily destroy the radiator when it does come apart?

Using a pull design with air dams will be more beneficial than any push fan over the long term. Who really wants to cut out the front of their bumper for a fan anyways?

 

Speaking of push pull fans, has anyone ran a slim push fan between their ic and radiator? Kind of curious since it seems doing it that way could help gain some engine bay clearance without much sacrifice. Thats assuming theres enough space between the ic and rad for a slim fan.

 

Spall fans are designed to pull air, Spall does not recommend using them as a "push" fan, they will work but not as well, [straight blades will work better then curved blades].

We use the "Made in the USA" Derale pusher fans when we need a pusher, not cheap but the best we have found...

Yea I was referring too front mounted vs rear mounting.

I think I figured my problem out with a spal fal

And yea spal makes both push and pull style fans.

Thanks everyone for advice
