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

THIS IS THE BOLT-ON STYLE PULLEY KIT. CHECK YOUR CAR FOR COMPATIBILITY.

The CTS pulley has a smaller diameter than stock. The Stock pulley size is 63.25, and 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.

Stage 2 Software is required to optimize the pulleys performance. Check out the single pulley stage 2 tune from Integrated Engineering for your 4-bolt supercharger! 

Stock pulley size: 63.20mm

CTS pulley size: 57.30mm

Please check your supercharger pulley to make sure you have the proper part.
