The Perrin alternator pulley decrease rotational mass and which helps to improve your performance and engine response time.

Red perrin alternator pulley

Installed a fluidampr hatmonic balancer which is a bit heavier than the stock crank pulley so I decided to Install some lighter pulleys to balance out the stress on the engine and get back some hp. The red looks great. And I can feel a slight increase in the speed at which the engine revs which is an intended and pleasant benefit
