This pulley is a smaller diameter than stock, at 57.3mm, increasing the speed at which the supercharger spins, and 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 the supercharger or engine components.

NOTE: This Supercharger Pulley Upgrade Kit must be used with appropriate “Stage 2” performance software, such as our GAS ECU Software. There will be no power gains if you install this pulley without Stage 2 software.
Stage 2 performance software 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.


Stock pulley size: 63.20mm

CTS pulley size: 57.30mm
