Ok, so...I just ordered ps. and atl. pullies off of ultrarev.com for my h22a1. Even though its a little to late to be asking now, I can run these to pullies together without changing the belt size correct? Im positive they to most of there underdriving off of the crank but I didnt want to have to worry about that crap. I know I'll most likely notice no difference but Ill feel better lol. They were the Ultra A' series if that matters. SO MY QUESTION IS, ARE THE UR PS. AND ALT. PULLIES STOCK DIAMETER?

 

Wait, so you ordered the alt and ps pulley but not the crank pulley?

 

yes thouse pulleys are stock diameter for them to even be worth it you would have to buy the crank pulley. if you read what they put in the descriptions, they state that they dont make underdrive pulleys. all the power comes from their crank pulley and the ps and alt are mainly only for looks

 

Ok yea thanks. I only bought ps. and alt. pullies. Untill there is a definite answer on the whole spinning bearing things I dont what to get a crank pully, plus I didnt have enough money. I mean they have to be lighter than stock so a might gain 1 rat-power if im lucky I have a pretty killer sterio system in it so I didnt feel like it would be smart to buy AEM either
