Pusher Fans

[Vins Quijano]

How would I wire up the pusher fans in between the intercooler and the ac condenser?

For pusher fans you switch the wires so ground is now +12v and +12v is now the ground. Most companies provide this info with the purchase of their fans.

Dont forget that on some (at least on mine) you may need to reverse the fan blade (turn it over). Remove the nut in the middle and gently remove the blade and put it back on the other way. If you test the fan in pull and push modes I think you will find that the push is not as good until you reverse the fan blade also, or it worked MUCH better on my twin pushers when I would bench test them. Just a suggestion before you mount them, test them both ways and use the way that pushes the best. This was on fans that were sold as both pullers and pushers not specific pusher fans FYI.

Did you turn the fan blade around just because or did the manufacturer tell you to do it?

Just curious as I have a 12" mishimoto fan set up as a pusher and all they said to do was switch the wiring.

They were no name brand fans so I just experimented with them because i have a 12 volt power supply in the house. I reversed polairity first but wasn't impressed with the "push" they gave so I turned the fan blade over and it pushed so much better that it was obvious that it should be that way to be used as a pusher (they were sold as pullers/pushers). Now my SPAL was specific and was correct when I got it but I still tested it anyway, better to test before you mount them then to have to unmount and buy new straps was my reasoning.
