Which pulley will my Whipple Supercharger kit come with?
Every supercharger will make different boost on different vehicles. There are many variables involved, one being the supercharger pulley.
Below is a chart, for your reference, letting you know which size pulley comes with each Whipple Superchargers kit AND the approximate boost level it will be at (considering the vehicle is basically stock, otherwise).
