APR Supercharger Pulley for Audi 3.0 TFSI Install Kit
La polea de la unidad de la unidad del sobrealimentador de fábrica Gen 1 se presiona en el eje de entrada del sobrealimentador. No es posible eliminar la polea de fábrica sin daños, o dañar el sobrealimentador en sí a menos que se llame especial cuidado y atención. El kit de instalación de la polea de la unidad de superchivo APR está diseñado para encapsular toda la polea y tirar de manera uniforme a toda su superficie. La unidad es lo suficientemente compacta como para no requerir la eliminación completa de la parte delantera de su vehículo, reduciendo el tiempo de trabajo. Además, se hizo una provisión para incorporar una barra de interruptor de transmisión de 1/2 pulgadas que permite que todo el ensamblaje sea fácilmente contrarrestado y, en última instancia, hace que el proceso sea un trabajo de un hombre.
Un manual de instalación completo cubre el proceso de instalación de principio a fin, lo que permite completar la instalación fácilmente en cualquier concesionario de APR o en tu propio garaje.
APR presenta las mejoras de la Polea del Compresor y la Polea del Cigüeñal 3.0 TFSI.
La actualización de la polea de transmisión y la polea de cigüeñal del Supercharger de APR aumenta drásticamente la potencia y el par al aumentar la velocidad de rotación del supercharger de fábrica. La actualización de la ECU de la polea de la Etapa II de APR realiza los ajustes necesarios en la gestión del motor para manejar las velocidades aumentadas del supercharger y, a su vez, permite que el motor genere más potencia. Las poleas se venden por separado, lo que permite múltiples niveles de rendimiento, cada uno de los cuales se basa en el anterior. ¡Finalmente, cuando se combina con la actualización del cuerpo del acelerador Ultracharger de APR en una configuración de doble polea, el sistema se libera de las restricciones de entrada que roban potencia, lo que permite que el motor alcance emocionantes niveles de rendimiento nuevos!
APR Supercharger Drive Pulley Upgrade
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 Supercharger Crank Pulley Upgrade
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.
APR Supercharger Dual Pulley Upgrades
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 Stage II ECU Upgrade
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.

| - APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode. | |||||
| - Max increases are based on APR's actual measured stock values and not those reported by Audi. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades. | |||||
| - Reported wheel figures measured using APR's in house dynos using SAE J1349 correction and an average of multiple runs for all figures. Crank figures are estimated based on the measured wheel figures and APR's engine dyno results. Results will vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. For the best results, APR recommends removing the intake snow screen. | |||||
| - Please note, transmission software is required to achieve power figures past the factory redline. | |||||
