Alternators are supposed to be limited to 15K-16K RPMs to prevent the rotors from self destruction. I am running a Innovators West 7.75" overdrive balancer and can spin my motor well over 7K...although I currently limit it there. To protect the alternator from self destruction, I really should have a 3.6" pulley on it. Here's the question....does anyone know where I can get such a thing? The alternator is a 6G V case as I have a 2006 Mustang GT. I'm running an 8 rib belt setup...and I would prefer that the pulley be nice looking ...preferably clear anodized Billet Aluminum. All of the other pulleys are billet aluminum on my motor.

 

Bump...no one has an opinion or idea where to find such things?

 

You could try powder coating to at least somewhat match it.

 

I don't have any. What I'm trying to find is an 8 alternator rib pulley for an 06 Mustang GT that is around 3.5" diameter. I can't find any sources?

 

Still no leads on sources underdrive alternator pullies?

 

Try PA Performance alternators 877-471-8010

They had a different size alternator pulley I needed for my SC install

Not saying they have it but they might know where to get it
