CTS Turbo B8.5 S4, S5, Q5, SQ5; C7.5 A6, A7, A8, Q7 with 3.0T (Gen2) Engine Supercharger Pulley - BOLT ON STYLE (CREC engine code)

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 THIS IS THE BOLT-ON STYLE PULLEY KIT. CHECK ON YOUR CAR FOR COMPATIBILITY. We recommend replacing the pulley bolts during the installation. CTS 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. NOTE: CTS 3.0T Supercharger Pulley Upgrade 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 while safely optimizing air-fuel ratios, timing, and boost pressure bleed off. Most Stage 2+ software tunes are compatible with this kit. Product Details
