The CTS Turbo crankshaft pulley kit for the Audi S4 B8 and Audi S5 8T 3.0 TFSI is manufactured from precision-machined T6061 aluminium. This pulley has a larger diameter than the original two-piece pulley and is available in diameters of 180mm or 187mm, depending on your desired boost target. This upgrade not only reduces the crankshaft’s rotating mass but also increases the speed at which the supercharger rotates, resulting in higher boost pressure. This results in a significant increase in power and torque across the entire rev range without placing any additional strain or causing wear on the supercharger or engine components.
