i was looking at super street yesterday and noticed the AEM pulleys they put in were much larger than the o.e. pulleys they replaced and i got to thinking...hum ...the aem undrive the accessories by being larger therefore turning less...and then i said hey...if the UR achieves under drive by making the crank smaller therefore turning the accessories less then dont the 2 almost offset? i think so ...it had always been said you cant use the 2 together but i think you can and maybe maintain noraml accessory out put but have lighter pulleys...ofcourse this is only for the person that alreay bought the AEM and now wants a crank pulley...because if you're starting from scratch well you could just by the UR street charger pulley with no under drive

 

after thinking about what i just wrote im pretty sure im wrong...the accessories would just be under driven more? and if thats correst you could still just buy the new chrager pulley and be in the same boat as before ,except 6 lbs lighter

 

yeah, the accesories would be way under driven. I spoke to someone at aem and someone at UR and they both looked into the others pulley specs and said the combo would be dangerous.

 

Interesting thought though TypeR

 

i heard not to mix them.
