Lightbulb Poll : Push vs Pull

Ok, well, heres the question, do you guys prefer push through rad, or pull from rad, when it comes to electric fans.

Me personally, I prefer the pull method.

Even though the water is supposed to do that cooling, and forcing the air through the radiator would be optimal. Also I would think that with the push method, the air being forced though would sort of diffuse and not really have enough velocity to make it to the motor without petering out.

With pull, it seems to blow some air over the exterior of the motor, and obviously suck some through the radiator. Only downfall I really see to this is some people would not like the aesthetics of the fan being there and cluttering up the compartment.

But no matter what, either way you GOTTA have a shoroud, or none of that fan action is going to seeing places it needs to be.

Push/Pull

Which kind of fan you use depends, for the most part on location, location, location.
Most conventional setups use a pull fan, but there are applications, due to limited space between the radiator and engine or other chassis designs where a push fan would be absolutely required. I too prefer a pull fan, but as I stated, that is the conventional setup and if it aint broke, why fix it?

One should go with a push system only if that is the last resort. I have seen rodders with a mechanical fan having a run hot condition install a push fan and the problem get worse because the added fan restricts airflow to the radiator.

pull time

z28: that is exactly what happened to me. The pusher seemed to block more air from the mechanical and it just got hotter. A Doubler puller in it's own shroud mounted right on the radiator did the trick./...of course the new Griffin aluminum radiator helped too

You loose 20% efficiency in push mode.
