The NST Underdrive Crank Pulley is intended for n/a or turbo applications. This pulley should not be used with a supercharger because it would lower PSI on such an application.
You can use the NST CR-Lite on n/a, turbo, or SC applications.
You can use the CR-Lite now and keep it installed once you install your supercharger.
Perfect. Just the answer I was looking for. Looking to purchase real soon.
