Hey guys

I was told that simply installing a electric radiator fan will improve power? How does this work?

And Also where can you find ASP Underdrive pully for a 4.7?

Need some professional advice!

 

The mechanical fan draws considerable engine power, especially in traffic when the motor is hot (the clutch is engaged under those conditions). The efan draws power off the alternator. The effect on the engine is much less to spin the alternator.

Kinda looks like ASP doesn't have a pulley for that motor:
