APR - aprMS100184 - Supercharger Drive & Crank Pulley Kit with Belt

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.

Brief Description

The APR Supercharger Drive and Crank Pulley Upgrade increases supercharger speed for increased horsepower and torque across the RPM range when used with appropriate software. The dual-pulley configuration spins the factory supercharger approximately 26.4% faster than stock. The kit includes a press-fit 57.75 mm supercharger drive pulley, a bolt-on 187 mm crank pulley, and the appropriate belt.

Key Features & Performance Benefits

• Increased Supercharger Speed: Spins the supercharger approximately 26.4% faster than stock for increased horsepower and torque with tuning.
• Dual-Pulley Configuration: Combines the supercharger drive pulley and crank pulley upgrades for higher supercharger operating speed.
• Durable Construction: Uses CNC-machined billet stainless steel for the drive pulley and lightweight billet aluminum for the crank pulley.
• Factory-Oriented Installation: The drive pulley press-fits to the factory supercharger, while the crank pulley bolts over the factory harmonically balanced crank pulley.
