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. \n \nTHIS IS THE PRESS-ON STYLE PULLEY KIT. CHECK ON YOUR CAR FOR COMPATIBILITY. \n \nCTS 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. \n \nNOTE: CTS Supercharger Pulley Upgrade Kit must be used with appropriate "Stage 2" performance software. \nStage 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. \n \nMost stage 2 software is compatible with this kit. Contact your tuner for compatibility. \n \nStock pulley size: 63.20mm \n \nCTS pulley size: 57.30mm \n \nProduct Details \n
