APR Supercharger Dual Pulley Upgrade for Audi 3.0 TFSI

Category: Tags: , ,

APR Supercharger Dual Pulley Upgrade for Audi 3.0 TFSI dramatically increases 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.

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.
