Any idea or experiance on how well these would work/worth it?

Electric Water Pump Pully.
My idea is to have this in series with an E-Fan and Drop My AC Unit To Reduce Drag on the motor. Ive always said 4 Bangers would have more power if they would stop stumbling over themselves. nows a chance to find out for me :)

 

heres the link on jegs, but im not sure if it will fit/ mount up. It doesn't say anything about anything else but the vehicles listed.

grrr.... autoparts warehouse has vehicle parts by listing of the vehicle if that makes any sense. and it was listed there. yet when you go to look at it you cant find the truck on the list.
