Quick question...is a pusher or puller fan more effective?

for our cars as well as rx7's they use pullers. so I guess theses are more effective. I see pushers on old cars not new ones.

Don't think it makes much difference except for packaging. Just make sure the fan is shrouded.

One thing's for sure, there weren't no pushers until electric fans came into being. I never saw one until the late '70s on a Rabbit or some such.

pull

pullers because they dont block any air coming into the radiator

I think I heard somewhere to use a pusher...but mounted on the other side (front) of the radiator...?

Well Danny,
I can't tell you which one is more efficient. I will drop a banana out my a** & say that i would think pullers are better because the air flow thru the rad should be smoother for more complete heat transfer.
What i know for sure is that traditionaly in RWD vehicles the fan was belt driven puller. With the advent of common FWD platforms there is no convenient way to have it mechanically driven so that's where we get electrics. Freeing up the fan it can be mounted behind or in front.
It's interesting most recent BMW's (like mine), have the tradtional belt driven puller AND a 2-speed electric mounted as a pusher. Just in case. Damn these cars are overbuilt.
Bruce has got a point bout the shrouding, that will make the most difference.

Ok I am going to switch my to pusher and move them in front of the radiator to make more room for my bigger turbo

Does Chris Allen ever post on this board? I think he was the one that told me to get a pusher and mount it in front.... Anyways as if it matters on my car.... I've got PLENTY of room in the engine bay (all motor) hehehe....

yeah about the all motor thing sorry to here that! :cool:

i know im brining back a thread from the dead, but i thought i saw a write up on how to put the fans in front, i know it prolly wont be that hard and really doesnt need a write up to do, but id like to know what im getting myself into before i start

ill keep searching for the thread while im waiting for an answer, im "working" at wonder lube, so i got extra time to search

check with Justin (Ninety-nine-sel) on here.. I remember he did some on his car
