I measured the pulley on my Vortech supercharger and it measures about 3.75" in diameter. I looked on their website and it must be the 3.80. That pulley is giving me about 6psi of boost right now. I want to up it just a little for some more power. I'm thinking 7-8 psi. Any tips on which pulley I should pick? Also, is a 1-2 psi boost going to be noticeable? Thank you for any and all help.
