I am guessing this will only be in the summer time though when you do use your AC.
And as for the HP increase with 5.4, I doubt it would be anything noticeable, all it is doing is freeing up a clutch.
The biggest outcome from this would be to lessen the miles on your water pump.
I would spend no more than 200 on a total setup.

I do plan on doing this mod tho on my 5.4

I'm looking at about $275 with the setup I plan to get. I'm ok with that amount, as it seems to be a quality kit that I can rely on. I'll most likely drop in some UD pulleys at the same time, so hopefully I'll notice a little more HP increase by doing the two mods together rather than just the e-fan upgrade.
