Pulley swap

[Nice rig]

I am kicking around the idea of changing out my pulleys to free up some extra power. Any recommendations or things I should be concerned about? I have also been told about light weight pulleys vs. smaller ones. Thanks

What pulleys are you planning to swap? Also if you are looking for a magic HP increase, look elsewhere as it only helps a little bit and only at high RPMs too.
