Vortech si Upgrade A2A V1 setup Questions
 

Hi All

Currently have the following mods:

G37 Coupe w/Topgunz A2A - V1 Kit
9lb Pulley
TBATT Anti slip kit
- Highest boost seen.... 9.5lbs

Just sent supercharger unit into Vortech for the SI upgrade. Anyone recommend a different pulley to help with boost? Would like to hit the 12LB range. I've read about adding a 3.0 pulley to the mix but unsure which pulley that would replace. Any pics/or links are greatly appreciated!

Thank you!

You'd change the supercharger pulley. You'd have to go to a 2.95
