CTS Turbo is proud to release our 192mm Dual Pulley Upgrade Kit for Supercharged 3.0T V6 engines (press-on style). The smaller diameter supercharger pulley and larger diameter crank pulley 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 drastically increase stress or excessive wear on supercharger or engine components. This kit features press-on style supercharger pulley. Check on your vehicle before ordering! NOTE: This kit must be used with appropriate "Stage 2+" or equivalent performance software. Please contact your tuner. Use of upgraded heat exchanger is highly required.
