i have the afx udp and i noticed it revs up a bit faster, but i wasnt able to really feel any difference. also, i am kind of using one of my friends cars as a baseline, and i beat him a little bit more after i got the pulley put on. i think it is a good mod just for the price
crank pulley is usually smaller or larger than stock.. the alternator is usually just a lighter pulley...if ur low on cash pick up the afx, if u wanna spend a lil more pick up the Focus Central 3 pc pulleys. comes with crank, smaller, waterpump, larger, and a lightened alternator pulley. also retained the stock belts. i have the 3 pc and love it
How easy did the FC 3 piece install. I am looking to get that as my first mod and was looking at my stock ones the other day. To a person who has never done this sort of thing before, it seems pretty cramped. Are special tools required to do this type of swap?
scoots the install went very easy.. just the alternator pulley was a pain. but hell u payed for three, put it on...will just take a little time unless u dun have an impact around, then sell it as an aem udp
...also after driving some after the install, check the water pump pulley to make sure its all in check...also u may need to do a little sanding on the cover for the crank pulley to get a good fit when u put the cover back on
