This is a press-on pulley kit. Check compatibility on the vehicle before installation.
The CTS Turbo pulley has a smaller diameter than the standard pulley. The standard pulley measures 63.25 mm, while the CTS Turbo pulley measures 57.3 mm. This makes the supercharger spin faster, increasing boost pressure. Combined with upgraded ECU software, the increased boost pressure provides a noticeable increase in power and torque throughout the rev range. According to the manufacturer, this does not increase the load on or cause excessive wear to the supercharger or engine components.
Note: The CTS Turbo supercharger pulley upgrade kit must be used with suitable Stage 2 performance software.
Stage 2 software is not included. It enables the maximum boost pressure and power to be achieved from the supercharged 3.0T engine, while safely optimising the air–fuel ratio, ignition and boost pressure relief.
Most Stage 2 software is compatible with this kit. Check compatibility with the software manufacturer or tuner.
