Pusher fans

boxhead · #1 (**permalink**) 08-23-2011, 07:43 PM

Looking at mounting my pusher style fans pretty soon.
Does anyone have measurements, or clear front on (level) pics of pusher fans in the nose of genuine cars?

I can then "guesstimate" how far above centre line of openning the fans need to be.

Cheers.

Hi Boxhead, I put my fans about 1" from the radiator. They really push some air through and look great as they slowly start to spin as you take off from a standstill!

Regards.

This one is genuine Dave but not quite level.

Cheers Mando, do you also run a fan inside? or just work from pusher fans.

Merv, that is a helpful pic, shows they are up almost as far as the body will allow.

Hmmm, actually Merv, that pic raises another question, I always thought the fans where fitted with teh motor section out front (so fan blades are as close as possable to radiator, but that pic shows blades are out, with motors behind.

Is there a "right and wrong" way?

I realise these are all replica's but I thought they mounted this way around?

Your right Boxhead, that's the first time I've ever seen the motors against the radiator. I run the commodore shroud and fan on the other side of the radiator.

Regards.

Original-type setup...motors out.

Maybe Im the only one thats just realised that

Yes Andrew, it is certainly more iconic than real. And I agree many of us have liked it. I have no idea of the history of this image, but maybe someone from the US can let us know?

The fans in front of the radiator are very inefficient....apart from looking the part they blow very little air through the radiator... to start with the centre of the fan blows no air you only finish up with a ring of air blowing into the radiator...cooling a very small area of the total area of the radiator .....the only way to get air pulling evenly through the whole radiator is to have the fan on the back and a shroud must be used to pull air through the entire area of the radiator...... not just in front of the fan...

Hi Guys

For the fans to work efficiently and move maximum air through the radiator the fan blades need to be as close to the radiator as possible.

The blades can be a foot away from the radiator...providing you use a shroud the air will still be drawn through the radiator....evenly

Cheers guys, the pushers are purely for "the look" as I will keep the commodore fan on that I have used for the past 11000kls.

So the pushers dont need to actually do any cooling.

so just mount them whichever way looks cooler

seriously though, unless the motors are reverisble, the motor in or out decision has already been made for you, as they will spin in a certain direction and if mounted "backwards" they will actually push air AWAY from the radiator!
