Description

The Jackal Motorsports 207mm Lower Pulley is an upgrade designed to enhance the performance of Audi 3.0T Supercharged platforms. By increasing the diameter of the crank pulley, it allows the supercharger to operate at a higher speed, resulting in increased boost pressure, stronger midrange torque, improved top-end power, and more responsive acceleration. It is constructed from 6061 billet aluminum and features an offset install design with alignment indexing and an included alignment stud for easier installation. Upgraded Grade 12 hardware and Loctite are included for a secure fit. This pulley is compatible with various Audi 3.0T Supercharged models, including the B8/B8.5 S4 & S5, C6/C7/C7.5 A6 & A7, Q5/SQ5, and Q7 (4M/4L), as well as all EA837 and CREC variants. Important modification is required for installation. A nub on the engine block just below the tensioner must be cleared by cutting off approximately 10mm to prevent interference with the belt and avoid belt loss.
