Description

The Unitronic Dual Pulley Upgrade Kit is designed to enhance the performance of 3.0TFSI engines. The components are crafted from robust 6061-T6 aluminum, featuring a durable black anodized finish for both corrosion resistance and a sleek appearance. The kit comes complete with genuine Audi crankshaft bolts, ensuring a reliable installation. For maximum performance gains and drivability, this pulley kit must be used in conjunction with Unitronic Stage 3 Performance Software, which is sold separately. Combined with the required Unitronic Stage 3 calibration, this dual pulley system is engineered to produce a maximum of 493HP and 441 LB-FT of torque. The calibration is specifically developed to work harmoniously with both the supercharger and crank pulleys, maintaining OEM-like reliability. Installation difficulty is rated at 4 out of 5. This kit is specifically available for B8/B8.5 S4/S5, C7 A6/A7, and SQ5 models only.
