Description

APR's Supercharger Drive and Crank Pulley Upgrades dramatically increase horsepower and torque by increasing the rotational speed of the factory supercharger. APR's Stage II Pulley ECU Upgrade makes the necessary engine management adjustments to handle the increased supercharger speeds, and in turn allows the engine to create more power. The pulleys are sold separately, allowing for multiple levels of performance, each of which builds upon the other. Finally, when combined with APR's Ultracharger Throttle Body Upgrade in a dual pulley setup, the system is alleviated of power robbing inlet restrictions, allowing the engine to achieve exciting new levels of performance!

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 on Gen 1 models and bolted on on Gen 2 models with new OEM bolts.

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.

Please note: For 3"0 TFSI Gen 2 engines (Simos 16), the Supercharger Crank Pulley is only available when used in a dual pulley configuration.

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.

APR's Stage II ECU Upgrade is designed for use with each pulley upgrade and only needs to be purchased once. The upgrade builds upon the APR'stage I ECU Upgrade, reconfiguring the engine management system to work in conjunction with the higher boost pressure and airflow levels achieved by spinning the supercharger faster. The Stage I ECU Upgrade is required to purchase the Stage II ECU Upgrade.


Product Note

A new Supercharger Belt is required.

APR'stage II software is required to run any upgraded Pulley configuration and is sold separately.

This product is designed for use with APR's S Tronic TCU Upgrade, NGK BKR9EIX plugs gapped @ .024? +/- .002'torqued to 3"Nm and a new supercharger belt. The APR'supercharger Cooling System is highly recommended and required with the dual pulley setup. IAT's must be below 75c to achieve the advertised power figures. A high flow intake system is highly recommended and an intake is required to meet the advertised power figures. For the best results, APR recommends removing the intake'snow screen.
