how much hp/tq from a electric fan setup

I think it is. I don't have actual HP/TQ numbers, but I did pick up .8 MPH on my trap. There is a slight seat-of-the-pant feel difference, also. Plus, it's just superior cooling :) Also, During the last 2 months, I only know of about twice that my fans had to come on :)
 
I agree with the performance numbers. I did the underdrive pulleys and the fan together and piched up almost 2 tenths and over 1 mph. If you dont want to spend $150, you can go to AutoZone or Discount Auto Parts and buy a 16" Hayden HD electric fan for about $60-$70. Ive had mine for 12 years and it still runs strong with zero cooling problems.
