Can you expect to gain on an 04 4.6 with E-Fans and pulleys?

 

on my 5.4L I'd say you'd gain around 8+hp with the e-fans, pulley's are very little and you pay for it in the top end. Good luck.

 

how much did you pay for your pulleys josiah? and how much to install

 

I paid 188+shipping from Troyer, they're basically ASP pulley's. I did the install myself so it did not cost anything. If you're a decent handyman you can tackle any of the mods I've done, besides you have many on here who are willing to help if you're in a bind. I would never recommend the pullies to anyone however unless you're looking for a little more low end and less top.
