how much hp can i expect to gain with a water and a crank pulley?
is it even worth it?
4-5hp +/- depending on mods
IMO it is the best "cheap" mod out there to free up 2-4HP. But your not exactly going to feel anything by changing it.
It was one of my favorite mods, the power is nice and in the lower rpm range versus most other mods.
It's one, if not the best, bang for your buck mods out there.
I love my pullies. I felt a huge difference. Specially in the hot weather when i wanted to run A/C.
I didnt notice any power gains with mine but you can def tell that its doing something. The engine revs quicker, and there seems to be some increase in throttle response.
I have the AFx UDP, got it used for 75$ with the belt. One of the best mods I've done so far on the focus.
