Vortech Supercharger System w/ V-3 Si-Trim & Charge Cooler - Satin (2006-2010 Jeep Grand Cherokee SRT8) (4CK218-020L)
CARB-Legal V-3 Si-Trim Supercharger System for 6.1L Jeep SRT8
The Vortech V-3 Si-Trim Supercharger System for the 2006-2010 Jeep Grand Cherokee SRT8 is a complete, fully calibrated, and 50-state emissions-legal solution engineered to deliver substantial, reliable power gains while maintaining factory drivability. Designed specifically for the 6.1L HEMI platform, this system utilizes Vortech's advanced V-3 Si-Trim centrifugal supercharger paired with an air-to-water dual-pass charge cooler for consistent performance and thermal control.
At the factory redline, this system increases output to an impressive 560 horsepower and 510 lb-ft of torque at 8 PSI on an otherwise stock engine using 91-octane fuel. Vortech's centrifugal supercharger technology delivers superior airflow efficiency compared to roots-style blowers, producing more usable power with less heat and reduced parasitic loss.
The included V-3 Si-Trim supercharger features Vortech's patented oil control system and a state-of-the-art compressor stage developed in an SAE J1723-compliant supercharger test cell. With an industry-leading 78% adiabatic efficiency, the Si-Trim generates cooler discharge temperatures, improved durability, and strong power delivery across the RPM range - all in a compact, lightweight package that weighs significantly less than competing designs.
