Additional pulleys in various sizes to suit our modular hub/boost upgrade kits.
- These cannot be installed without our hub as shown here.
- The 2.42" (20PSI) pulley is made from high grade steel and due to the precision engineering involved in the design and manufacturing process compared to the other pulleys, they are an additional $50.
We do not recommend fitting a pulley smaller than 3.4" (10PSI) on a stock supercharged V6. Excessive boost pressure may induce knock and potential engine damage. A physically smaller pulley can only be used when the motor is intercooled, cammed and dyno tuned or has a combination of all 3.
Please contact us if you have any questions or concerns regarding this warning.
