I already have the AEM pulley kit but I want the crank also. My question is will there be a problem if I run the AEM pulley with the UR Crank Pulley?

Mr.T

 

Be careful with the UR crank pulley. It is a highly debated topic. I don't think you would have trouble if you decide to go with it.

 

The key here is you shouldn't have problems mixing pulleys. The longevity of your engine running the UR crank pulley is debateable.

 

"The key here is you shouldn't have problems mixing pulleys"

Thanks for the clarification NSXNEXT. It was reallly late last night when I tried to answer.

Mr T, NightHawkBlack has the complete UR pulley set. You might ask him how his crank pulley is performing so far.

 

what do the pully's give the car???? sorry if the question is stupid , kinda new at moding cars...

 

This is what I've gathered from reading and using the search button. I was wondering the same question yesterday. Anyone, feel free to jump in and flame me if I'm wrong here.
Pulleys are the little devices that the drive the belts in your car. The heavier the pulley, the more power it takes to spin it up to a given circular speed. Take off the stock pulleys, which are heavy and replace them with light weight pulleys of same size and that turns into less lag time for get-up-and-go. Replace stock with horribly crafted un-ballanced aftermarket pulleys and you have a thrashed car with a voided warranty. Replace with different sized pulleys and you may get better speed off the line, but at idle, your alternator is now spinning slower (since it's on the belts affected by these pulleys) and therefore voltage is lower than it should be. I think that's it in a nut-shell.

 

I ahve them all, and the pictures are here: http://www.flwse.com/images/nashua/

no problem so far The complaint is that the new gates belts are bit more noisy at idel... they squeak a bit.. and they need to strach to stop being noisy...

 

can u put on new pully's but keep the same belts?? and is it better to go bigger pully's or smaller to get better power???

 

no... new pulleys new belts... get UR pulleys and with new belts speced by UR.
