CTS pulley is smaller diameter than stock. Stock pulley size is 63.25, the CTS pulley is 57.3mm; it will increase the speed at which the supercharger spins and will increase the boost pressure output.   Increased boost pressure in conjunction with upgraded ECU software results in a dramatic increase in horsepower and torque throughout the entire powerband.  This will not increase stress or excessive wear on supercharger or engine components.

CTS Supercharger Pulley Upgrade Kit must be used with appropriate “Stage 2 performance software.  Stage 2 performance software (not included) will allow you to achieve maximum boost and power from your 3.0T S/C engine while safely optimizing air fuel ratios, timing, and boost pressure bleed off.

Most stage 2 software is compatible with this kit.  Contact your tuner for compatibility.  Please double check your supercharger pulley style before ordering.
