are the fans supposed to flow the same amount of air? ive noticed when they kick on the driverside fan flows more! so i turned the a/c on and both speed up but the driver side still moves more air is this normal? or is the passenger side getting weak

 

How do you know it's flowing more air?

It seems unlikely to me that they would both run but at different speeds.

^Agreed. Plus, with various accessories in the way on both sides (airbox/IC on passenger side, battery tray on driver's side), it'd be very difficult to tell regardless.

 

The four blade fan flows more than the five blade .I run two four blade fans as do some of my customers . The reason for the factory to use two different fans is to keep the harmonic noise down , thumping noise .I have not heard any of the two four blade set ups make the noise .If I remember correctly a new four blade fan is about $ 32 from the dealer .

 

im running a fmic and single turbo plus the battery is in the storage bin behind the driver seat so i can feel the difference between the 2
