CTS Turbo B8 3.0T Supercharger Pulley Upgrade Kit. By using a smaller than stock pulley CTS has been able to increase the speed at which the pulley spins thus increasing the boost pressure output from the Eaton supercharger. Increased boost pressure in conjunction with upgraded ECU software results in a dramatic increase in horsepower and torque throughout the entire powerband. Please note that our B8 3.0T Supercharger Pulley Upgrade Kit must be used in conjunction with the appropriate "stage 2" performance software. Stage 2 performance software, which is not included in this kit, will allow you to harness maximum boost and power from your 3.0T while optimizing air fuel ratios, timing and boost pressure bleed off. Please consult your preferred software tuner for pricing and availability.
