what is the fan supposed to do, other then drain your battery and tax your alternator?
First off, no, I'm not worried about two 12V fans draining the battery. :rolleyes:
At idle, the fans would assist in moving the air from the duct opening in the front bumper to the fender duct, and from there through the filter and to the throttle body... and when the TB is opened, more quickly through the runners.
Nearly 200cfm is better than the estimated 23cfm the intake receives at a stand-still.
The extra airflow from the fans should be able to help propel the vehicle from a stand-still, but I wouldn't expect much once you get to 4000rpm.
From what I've heard (
here), greater air speed = greater torque. With two fans pushing air to the TB --
even at idle -- there's bound to be an improvement when you hit the accelerator.
It all depends on whether or not two 100cfm fans is enough to show an obvious improvement. They may be completely unneccesary and could possibly hinder the airflow (though IMO, that's unlikely).
It doesn't seem that two fans would restrict air flow as long as the blades are spinning... but as with anything this weird and nubile, we won't know until I or somebody else tries it.
In sum, it's a kind of mock "electric turbo"; it's different only in that it's MUCH less expensive and... well, a little less professional looking.
Aside from the performance benefit, it's possible (isn't it?) that with the extra air blowing through the engine, the fuel would burn a little 'leaner' and conserve more fuel. Correct me if I'm wrong...
.RMk.. "I'll take on anything that even
seems like a good idea."
