W175FF 2.9L Stage 2 Intercooled Supercharger System

The Whipple WK-3110B-STG2 is a Stage 2 intercooled supercharger system featuring the Gen 3 W175FF 2.9L supercharger, engineered for the 2012-2018 Jeep Grand Cherokee SRT8 6.4L. This comprehensive kit delivers an impressive 200+ rear wheel horsepower gain, pushing the vehicle's output to over 600 rwhp. It includes all necessary components for installation, such as the supercharger, mounting brackets, pulleys, belts, an air-to-water intercooler, all necessary tubing and fittings, and even oil for the self-contained lubrication system. Additionally, the system comes with an MSD fuel pump booster, Siemens Deka 63 lb/hr high-flow fuel injectors, and spark plugs. The W175FF 2.9L supercharger is known for its efficiency, reaching 99% volumetric efficiency and offering industry-leading power potential with its front-feed design and helical-cut gears. For 2015-2018 models, a specific HP Tuners PCM is required for ECU recalibration and is included; customers with 2015+ vehicles may need to purchase a modified PCM for unlocking. The included tuning is optimized for stock vehicles or those equipped with a cat-back exhaust only. For vehicles with more extensive modifications like headers, mid-pipes, or camshafts, the "TUNER" kit (part number WK-3110TB) is recommended. This Whipple system is 50-state legal and includes a CARB sticker for emissions compliance. It features a massive oversized air-to-water aluminum bar-plate intercooler for superior cooling capacity, allowing for more boost and timing on pump gas. The system also boasts an exclusive 3x5 rotor combo for increased airflow and a flat torque curve for enhanced acceleration. Its unique intercooled bypass system contributes to excellent fuel economy during cruising by consuming less than 1hp.
