Spin your blower faster and make more boost everywhere in the rev range. The Jackal Motorsports 192mm crank pulley replaces the factory lower pulley on the Audi 3.0T supercharged engine, overdriving the supercharger for more airflow, more torque and more power from idle to redline.

Paired with an upper pulley, it's the foundation of a proper Stage 2+ dual pulley build.

Why replace the factory crank pulley?

The stock lower pulley is a known failure point, and its size caps how fast the supercharger can turn. Going up to 192mm gets you:

• Higher boost pressure
• More midrange torque and stronger top end
• Sharper throttle response and acceleration

What sets the Jackal pulley apart

Etched belt surface. Belt slip is the enemy of any pulley upgrade - if the belt slips, you lose boost. Jackal etches the belt contact surface for extra grip under load, so boost stays higher and more consistent at high RPM and from pull to pull.

Features:

• 192mm offset engraved on the face
• Indexed rear for correct orientation
• Alignment stud included to position the offset
• Designed to keep the belt tracking true
• Larger front opening for easy access to the bolts

Tuning required

A pulley upgrade changes boost and airflow, so your ECU and TCU calibration needs to match. Pair this pulley with a Jackal Motorsports tune set up for your pulley combination - available here at GAS.
