Pusher Fans

I have two original spec pusher fans on my Kirkham. They look great but I never use them.

Pick up a piece of debris or a rock, etc., thru the nose, have them hit a spinning fan blade and you can have a real hazard to your radiator or even your car's body. I have seen it happen. Were I to do it over, I would leave them off and just run a high quality 16" Spal high volume puller. Even without the hazard, more is just overkill.

My .02 cents worth.

I think Ron would know best, as he's done lots of research on the fan issue, but I THINK it goes something like this... comp cars had no fan, S/Cs had a single fan, street cars had the dual fans. Some S/Cs were probably converted to dual fan at some point as well.

On my car, I have the Spal 16 puller fan, and the dual pushers. I had the Spal go bad, and the dual pushers were definitely not enough by themselves. However, I had the ciruit overheat (all three were on one circuit) and I rewired them seperate and had to replace the Lucas relay for the pushers, and I can tell you that the 16" puller by itself, does not cool as well as all three together. So I run all three together and my car runs cool as can be even in 100* air.

Bud Man's right...they can create some "complications."

Had a good sized bird go thwump into the fans...a mess you wouldn't believe.

But I do like them. I think they add back the flow they cut off from their presence.

I just checked out my SPF last night regarding installing the pusher fans. I have the fan setup from Cobra Restorers with the single mounting bar. My SPF is a 2006, I am not sure they are all they same, but the should be similar for the recent cars.

There is a contour in the plastic filler, between the rad and wheel well with openings for the oil lines. There is almost a little ledge formed in the plastic under the hose opening. On the other side, in the wheel well, there is the top of the bracket that holds the bumper/overriders. A small square hole would accomodate the bar stock the fans are on and the bar would bolt on top of the bracket. Looks like the fans would be positioned at the correct height and far enough from the rad for no concern.

This weekend or next I get the fans in and post pictures.
