Thread: Pusher or Puller Fans?

So other than room in the engine bay. Are they REALLY any advantages of pusher over pullers?

pusher fans when not running reduce air flow to the condenser and radiator by being in the way. But who can deny all that glorious space free'd up moving the fans to the other side!

I did this on a turbo p11 and noticed zero cooling issues.

Do both Hwayne... lol One pusher one puller! haha.

I've always gone with one puller with my slim fans in my turbo car, and I went with 2 puller slims in my b14 because I have ac and a stock rad. If I could fit them I would go pusher if it was possible just for the space.

I agree

See... I would like to go slim just to clean up the engine bay some. I know the cfm's are not as I guess you could say high as the stock fans. But I'm not to sure if pusher's really help any.

In the past I have done straight water wetter/water combo and noticed a small decrease in the summer months. But moving up north now, heat really isn't that much of an issue..yet at least.

I just am interested what the benefits are on the N/A aspect.

pusher cools less when running then a puller and even less when not running, due to blocking airflow. There is no benefit to having it other then a cleaner bay with more room. This is of course going by same ccf fan.

Think of sucking through a straw with your mouth on it and now think of blowing through a straw with your mouth not on it. Which one causes more air to go through the straw? Reason pusher is without your mouth on it is due to the fact that you are not using a shroud. Shrouds are not recommended for pusher fans. I looked into this extensively before doing it a few years ago on my car.

I have always run the drivers side OEM fan and called it a day. I never had any over heating issues. This is with no AC BTW. If my turbo manifold allows it this time around I will run the same set up.

as stated pusher fans have their draw back but they free up space. I ran slim pullers with my ve car. I have have pushers mounted to the koyo going back into the ve car since its getting a large turbo. I also will be making some plates to better seal the radiator to air from going around it.

Wayne I would recommend the Mishimoto fan shroud kit. It looks nice and with 2 fans it should keep the car pretty cool. I am not sure if it would work with an OEM radiator tho.

I remember reading somewhere that a push fan is about 30% less efficient than a pull fan
