It allows the engine to rev up much quicker similar to that of a lightweight flywheel (but obviously not as pronounced). It can improve mid range pull as well but typically the biggest gains are at higher rpms. It reduces drag on the crank and in conjunction with pulley it makes a drastic difference in the way the car behaves. If you use a curved blade fan you can decrease fan noise as well. Another major difference is the electric fan runs at full speed all the time (steady rpm, unless you have adjustable controller) where as the mechanical fan is based on rpm.
On the older E36 M3 bmws it was very popular to just delete the old mechanical fan and run lower thermostat & aux fan switch... that alone was enough to cool the car, no additional electric fan was needed. Although it never actually made much on the dyno (a few HP at most) it transformed the way the engine would rev & behave so many people like it alot.
hope that helps.

P.S. If anyone wants the 14" fan in stock, will let it go for only $99 + $11 shipping with the wiring harness.

Hey, I know its a super old thread. however, I am going electric after a stuck clutch fan destroyed my brand new radiator.
Anyways, I am planning on using a thermostat sensor (not the stick in prob) and so I need a place to install in. Any suggestions? Can I use the current temp sensor and just splice into it?
thanks
