Do UD Pulleys Really Increase HP?
Hello! After changing the rear gears in my 1998 Convertible, I am looking for additional information on how to increase my hp without nitrous/supercharger/headswap. In other words, I am trying to build on my mod without being too radical. I have heard that underdrive pulleys can add hp (5-10) in a simple manner. I have also heard that they are mostly for looks and do not really add to hp. Any input here?
