Re: what are pully's?


pulleys turn things on your car like your crank and your alternator with the help of a belt.


the smaller the pulley the less strain on the crank therefore increasing horsepower by about 10

it's easy to install pulleys and they are about 150 bucks

mind you it also can hurt your charging system a tad.

The charging issue can be fixed with a special alternator pulley though

actually charging issues can be taken care of by leaving the stock alternator pulley on, and putting on the other two without losing HP
