Vortech Supercharger System w/ V-3 Si-Trim & Charge Cooler - Polished (2006-2010 Jeep Grand Cherokee SRT8) (4CK218-028L)
CARB-Legal V-3 Si-Trim Supercharger System for the 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 upgrade engineered to deliver major power gains while preserving factory-like drivability. Designed specifically for the 6.1L HEMI, this polished system pairs Vortech's proven V-3 Si-Trim centrifugal supercharger with an air-to-water dual-pass charge cooler to maintain consistent intake temperatures under boost.
With 8 PSI at the factory redline on 91-octane fuel, the system increases output to an impressive 560 horsepower and 510 lb-ft of torque on an otherwise stock engine. Vortech's centrifugal design delivers higher airflow efficiency than roots-style blowers, generating strong 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 produces cooler discharge temperatures, improved durability, and excellent power delivery across the RPM range - all in a compact, lightweight package.
