CTS Turbo upgraded crank pulley kit with a diameter of 187 mm for the Audi 3.0T FSI V6 supercharged engine.
The pulley has a larger diameter than the original and is made from precision-machined T6061 aluminium. It replaces the two-piece original pulley and reduces the rotating mass of the crankshaft. The larger diameter increases the supercharger speed and boost pressure.
For correct operation, the kit must be used with suitable engine management software. Suitable software enables safe optimisation of the air–fuel ratio, ignition and boost pressure reduction, while allowing the engine’s potential to be used. Software is not included.
