AEM pulleys? Lower voltage?
I have the AEM pulleys on my car and wanted to know if they cause the car to have lower voltage than normal. A lot of people say that with a standard setup the voltage is close to 14.4 volts. Does the pulley affect the voltage?

I just spoke with AEM and it decrease the voltage. The pulley is about 30% larger which means the Alt is not spinning as fast. They did say unless you have a lot of power(which I do) the difference isnt too much while driving. I'm removing mine only because I'm pretty much done using mar car for racing.
