CTS Turbo is proud to release our 3.0T Supercharger Pulley Upgrade for the Gen 2 3.0T CREC engines, commonly found in late 2016-2018 B8.5 Audi S4/S5 as well as A6, A7, Q5, SQ5 and Q7 \n \nTHIS IS THE BOLT-ON STYLE PULLEY KIT. CHECK ON YOUR CAR FOR COMPATIBILITY. We recommend replacing the pulley bolts during the installation. \n \n \nCTS pulley is a smaller diameter than stock. Stock pulley size is 63.25, the CTS pulley is 57.3mm; this will increase the speed at which the supercharger spins, increasing 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 3.0T Supercharger Pulley Upgrade 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 while safely optimizing air-fuel ratios, timing, and boost pressure bleed off. \n \nMost Stage 2+ software tunes are compatible with this kit. \n \nProduct Details \n \n
