Adding a pusher fan.

I AGREE ON THE MECH. BELT DRIVEN FAN BEING THE BEST , NO DOUBT ! I RUN ONE ! The pusher fan doesn`t hurt as much as u let on, it is turning when the car is moving, wheather it is on or off. Not like a solid piece of sheet metal in there, not near the restriction like ur saying . It does help a hi h.p. engine at a stop light, Yes it is a band aid, but if ur creating a lot of h.p. in a tite compartment , u do everything u can to keep it cool. The standard old stuff that works on most cars, go out the window when u get over 700 h.p. in a street car. I`ll use every band aid I can think of !!

I never said a mechanical fan was best. There's a whole bunch of reasons why pretty much all new cars come with electric fans, so saying that a mechanical belt driven fan is "best" is just silly. Maybe for certain applications, but honestly the OE electric fans out there now are more reliable and more capable than some old mechanical fan. That's why I run electric fans. You have much better control of what the fans are doing and when, so it's easier to keep the engine at the temperature it wants to be at without running fans when you don't need them and wasting power.

As for the restriction of a pusher fan, of course its not like a flat plate. It's not even as bad as say, hanging an AC condenser out in front. But if you think it doesn't cause a restriction you're just wrong. It does, and you have to address it. Just like Ma Mopar did when they upsized the radiators for the cars that came with factory AC.

If your cobbled together stuff works for you, great. If you want to run multiple inadequate fans instead of one that can do the whole job, be my guest. But if you do it right, you'll have better cooling and lose less power. If slapping a cheap pusher fan out front works what it actually means is that your mechanical fan isn't pulling enough air at low speed, and your radiator is big enough to cool the car. So the radiator is fine, the mechanical fan is underperforming, and the pusher is just trading efficiency at speed to band aid the inadequate mechanical fan at idle.
