4.0L Rear-Feed Intercooled Supercharger Kit

The Whipple WK-1830 is a high-performance 4.0L rear-feed, intercooled supercharger system engineered for GM LS-based engines, including LS1, LS2, LS3, LS6, and LS7 variants. At its core is Whipple's massive oversized air-to-water intercooler, providing unmatched cooling capacity to maintain optimal performance. The integrated twin-screw supercharger, a W245AX model with a 4.0-liter displacement, achieves 99% volumetric efficiency and industry-leading power potential. This specific kit includes the supercharger unit with its built-in intercooler and intake manifold system. It does not include a heat exchanger, piping, or fuel system components. The air entry for the supercharger must be positioned on the driver's side. Whipple Superchargers has been a pioneer in twin-screw supercharging technology since 1987.
