All CTS Turbo products are warrantied against manufacturing defects for a period of 12 months from the date of invoice. Warranty does not cover abuse, misuse, consequential damages, normal wear and tear, improper installation, or damages resulting from racing. Warranties only apply to the original owner.

CTS Turbo is proud to release our early model (before 2016) B8/B8.5 S4, S5, Q5, SQ5; C7/C7.5 A6, A7, Q7 3.0T Supercharger Pulley Upgrade Kit.


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 your tuner for compatibility.

Stock pulley size: 63.20mm

CTS pulley size: 57.30mm
