CTS Bolt On Supercharger Pulley Upgrade - Audi S4 S5 B8.5 CREC

This is the BOLT-ON STYLE supercharger pulley upgrade kit for Gen2 3.0T CREC engine commonly found on Australia 2016-2018 facelift Audi B8.5 S4/S5.

MUST be used with appropriate “Stage 2" performance software.

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.

- Smaller 57.3mm pulley
- Boost increased from stock 11psi to 15psi
- Made with AISI 4140 Steel at CTS Turbo in Canada
