Hey everyone! I’m new to the chat. I recently purchased a 2008 Land Rover Range Rover supercharged 4.2L. I have a buddy who makes pulleys. I’m going to have him make some new pulleys out of aluminum so I can swap when I get the new belt. I’m planning on upgrading the supercharged pulley to a 15%. He asked me “How much is a factory pulley that I can use the offset and Id measurements” and I can’t seem to find the answer. Anything helps thanks so much for your time!
