The Whipple WK-1100NFT is a W140AX twin-screw supercharger system engineered for 2003-2006 GM 4.8L trucks and SUVs. This intercooled "Tuner" kit, featuring a 2.3-liter displacement, is designed to provide substantial performance upgrades. Whipple Superchargers, a pioneer in twin-screw technology since 1987, presents this system utilizing their W140AX supercharger, noted for its 99% volumetric efficiency and industry-leading power potential. This "Tuner" kit specifically does **not** include tuning or fuel components, and requires a VIN number for ordering. It comes with a standard 1-year warranty. Whipple claims this system can provide up to an 85% horsepower increase (up to 275hp more than stock) and up to a 75% torque increase throughout the entire RPM range (up to 250 ft-lb more than stock). The exclusive 3x5 rotor combo is highlighted for increased airflow under the curve compared to less efficient 4x6 rotor combinations.
