CTS Turbo Audi S4 / Audi S5 3.0 TFSI Crank Pulley Kit
 
 
The CTS Turbo crank pulley, made from precision billet T6061 aluminum, is larger diameter than the two pieces OEM pulley, you can select a 180mm or 187mm diameter according your boost gain target. Not only reducing the rotational mass of the crank, this upgrade will also increase the speed at which the supercharger spins for more 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.
