underdrive pully I am building my car up I heard a upgraded underdrive pully is a easy way to get a couple Hp's. What's a good pully to buy and from where and will I need anything else other then the pully and belts for the install.

SLP makes a good 25% underdrive pulley with a belt retaining wall to prevent belt slipping which has been problematic for other brands of underdrive pulleys. Nothing else needed besides the new belts, they even supply you with a new bolt.

Crank Pulley Install Tool is recommended so that you don't damage your crank threads. There is a guy on the boards that sells one, just do a search. They are about $45 and you can always sell it once you are finished.
