Were do I get a smaller pully for my Vortech?
Stock blower pulley is 3.12 for the LS1 kit.
You can get a 2.95, or even a 2.85 from Vortech or a Vortech dealer. A 2.95 should increase boost by 1-3 psi, you can ask jsnee@vortechsuperchargers.com for his thoughts.
I run a 8.00/2.85 combo with my YSi. Saw 17 psi when I had a YS.
