The smaller the pulley, the faster the alt. will spin. On the flip side of things, the larger the pulley, the more rpm's it takes to turn it, resulting in less hp. (So I guess small is better in both ways.)..."are oversized so it takes less power to make them spin." - wrongThe larger they are the more power it will take form the engine to make it spin and the less power it will put out...."that is why people with systems complain about getting them because your alternator will actually be getting less power."I think he means to say it will actually be putting out less power. (If the larger ones are used that come w/ the kit.)</blockquote>
