W140AX 2.3L Twin-Screw Supercharger Tuner Kit

The Whipple WK-1113NFT is a cutting-edge 2.3L W140AX twin-screw supercharger system engineered for 2007-2013 GM 6.2L trucks and SUVs. Building on Whipple's extensive experience since 1987, this kit delivers significant power gains, with the potential for up to an 85% horsepower increase and a 75% torque increase across the entire RPM range. It features Whipple's exclusive 3x5 rotor combo for enhanced airflow and a massive oversized air-to-water bar-plate intercooler for superior cooling capacity. This intercooled tuner kit operates at 7-8psi of boost and is designed for both stock and heavily modified engines. The top-mount design promotes cooler operation compared to upside-down superchargers, and the discharge-down configuration minimizes pressure loss for better performance at lower boost levels. The system boasts an industry-leading air-bypass system for reduced burst knock and improved fuel economy during cruising. Key features include a self-contained lubrication system, a high-flow air filter and fuel injectors, and the ability to perform pulley changes in as little as 3 minutes. It is important to note that **TUNER KITS DO NOT INCLUDE TUNING OR FUEL COMPONENTS**, and a VIN number is required for ordering. The system is compatible with 2007-2013 GM 6.2L trucks and SUVs.
