Code: CTS-HW-0133


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.

NOTE: 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 us for compatibility.

Stock pulley size: 63.20mm

CTS pulley size: 57.30mm
