Ive never heard of this. . . but someone brought to my attention that lightened pullies and under pullies henders your system.
According to the guy, he used AEM pulleys as an example. . .

Is this true? And does it make for a substantial loss? Any help is appreciated....they are lighter...but the accessory pullies (like those included in the aem kit) are oversized so it takes less power to make them spin. that is why people with systems complain about getting them because your alternator will actually be getting less power.
