Jackal Motorsports 192mm Audi 3.0T Crank Pulley Upgrade｜ Other Products

The Jackal Motorsports 192mm Lower Pulley is designed to push the Audi 3.0T supercharged platform beyond its factory limits by increasing supercharger speed and overall boost.
By stepping up from the stock crank pulley to a 192mm overdrive setup, you increase airflow, torque, and power across the entire RPM range — making this one of the most effective upgrades for EA837 and CREC-equipped vehicles.
While most pulleys focus only on size, this one was built to address one of the biggest limitations in higher boost setups: belt slip.
Why Upgrade Your Lower Pulley?
The factory pulley is not only failure prone, but it limits how fast the supercharger can spin. Increasing the diameter allows the blower to operate at a higher speed, resulting in:

Increased boost pressure
Stronger midrange torque
Improved top-end power
More responsive acceleration

This is the foundation of a proper dual pulley setup.
What Makes The Jackal Pulley Different?
Etched Belt Surface (Reduced Slip, More Boost)
One of the biggest issues with pulley upgrades is belt slip.
Less grip = less boost.
This pulley features a precision-etched belt surface designed to:

Increase belt traction under load
Reduce slip at high RPM
Deliver more consistent boost levels
Improve repeatability between pulls

This results in more predictable and consistent performance compared to conventional pulley designs.
Precision Offset Install Design (Easy Installation)
This isn’t just a larger pulley — it’s engineered for correct alignment and repeatable installs.

Clearly marked "192mm" offset engraving on the front
Rear alignment indexing for proper orientation
Included alignment stud for easier installation
Designed to maintain proper belt tracking
Larger front opening for clear easy bolt installation

Upgraded Hardware Included
Everything needed for a secure install is included:

High-strength Grade 12 hardware
Blue Loctite for proper torque retention
Alignment stud for offset positioning
