The JLT 2.80 Pulley Upgrade for Hellcat is a popular modification among enthusiasts looking to significantly boost their vehicle’s horsepower. This upgrade not only enhances performance but also transforms the driving experience. With the potential to push horsepower beyond 700 HP, it’s a modification that many consider essential for maximizing their Hellcat’s capabilities.
Understanding the JLT 2.80 Pulley Upgrade
The JLT 2.80 pulley is designed to replace the factory supercharger pulley on the Dodge Hellcat. By decreasing the size of the pulley, the supercharger spins faster, resulting in increased boost pressure. This leads to more air being forced into the engine, which directly correlates to higher horsepower and torque figures.
Key Benefits of the Upgrade

The increased boost levels require adjustments to the engine’s air-fuel mixture and timing to ensure optimal performance and prevent engine damage. Many owners opt for a custom tune from a professional to achieve the best results.
Performance Results
Owners who have upgraded to the JLT 2.80 pulley often report impressive performance gains. With proper tuning, many Hellcat owners experience:
- Horsepower figures exceeding 700 HP.
- Improved quarter-mile times.
