APR 09-18 Audi A6/A7/A8 Quattro 3.0 TFSI Supercharger Drive & Crank Pulley Kit

APR's Supercharger Drive Pulley Upgrade decreases the diameter of the factory pulley from ~63.25mm to 57.75mm, which in turn spins the supercharger ~9.5% faster. This results in a healthy bump in horsepower and torque across the entire RPM range with the supercharger operating at a higher rate of speed. The pulley is CNC machined from billet stainless steel, e-coated black for an OEM appearance and is press fitted to the factory supercharger unit.APR's Supercharger Crank Pulley Upgrade increases the diameter of the factory pulley from ~162mm to ~187mm, which in turn spins the supercharger ~15.4% faster. This results in a larger bump in horsepower and torque across the entire RPM range, as the supercharger is spinning at an even higher rate of speed. The pulley retains the factory harmonically balanced crank pulley and bolts on top of the existing unit. It is CNC machined from light weight billet aluminum with weight saving pockets throughout. It has an anodized black finish and includes new crank pulley bolts.Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning ~26.4% faster than stock. This speed was chosen after extensive engine and chassis dyno testing with various pulley sizes and supercharger speeds. The result is an even higher horsepower and torque gain across the entire RPM range. However, at the airflow levels achieved with a dual pulley setup, maximum power is severely restricted by the factory throttle body unit. The APR Ultracharger Throttle Body Upgrade is necessary to take full advantage of the dual pulley configuration, and is available in platform specific variations for the B8/B8.5 A4/A4/S4/S5, Q5/SQ5 and C7 A6/A7.Belt IncludedSoftware sold separately Fits 2009-2018 Audi A6/A7/A8 Quattro - 2013-2017 Audi Q5 - 2011-2015 Audi Q7 - 2010-2017 Audi S4/S5 - 2014-2017 Audi SQ5 Please note, specific software is required to maximize output with this product.

The APR Supercharger Drive and Crank Pulley Upgrade for 2009-2018 Audi A6, A7, and A8 Quattro models enhances your vehicle's supercharger performance by increasing its rotational speed. The CNC-machined billet stainless steel drive pulley features a smaller diameter of approximately 57.75mm, reducing from the factory size and spinning the supercharger about 9.5% faster. This upgrade results in noticeable gains in horsepower and torque throughout the RPM range, providing a more responsive throttle and improved acceleration.

The accompanying crank pulley, crafted from lightweight billet aluminum with weight-saving pockets, increases in diameter from roughly 162mm to 187mm, spinning the supercharger approximately 15.4% faster. When combined, these upgrades boost supercharger speed by roughly 26.4%, unlocking significant performance gains. The factory harmonic balancer is retained, and the pulleys are designed for easy bolt-on installation using the included new crank pulley bolts. An anodized black finish and black E-coating ensure a factory OEM appearance that resists corrosion and wear.

To fully leverage the increased supercharger speed, an APR Ultracharger Throttle Body Upgrade is recommended, tailored for specific Audi platforms such as the B8/B8.5 A4/A4/S4/S5, Q5/SQ5, and C7 A6/A7. The kit includes a high-quality belt suitable for the new pulley diameters, though the software required to optimize performance must be purchased separately. Extensive testing has confirmed that these pulley upgrades deliver impressive power and torque improvements across the entire RPM spectrum, transforming your vehicle’s performance without compromising reliability.
