4.5L Gen 3 Twin-Screw Supercharger Kit

The Whipple 4.5L Gen 3 twin-screw supercharger kit represents a significant performance upgrade engineered for Dodge Hellcat 6.2L engines. Building on Whipple's legacy as pioneers in twin-screw supercharging since 1987, this intercooled system is designed to deliver maximum power for fuel-injected OEM vehicles. At its core is the massive 4.5 Liter Gen 3 twin-screw Whipple Charger, boasting over 88% more flow capacity than the factory 2.4L unit. This is complemented by the Crusher intake system, featuring a 123mm mass air flow housing and a true cold air intake with an oversized S&B 9" filter. The kit includes a wide mouth intake manifold equipped with an air-to-water intercooler that is more than twice the size of the stock cores, unlocking substantial power potential. The manifold design retains factory fuel rails and accommodates both short and mid-length fuel injectors. The 4.5L supercharger is versatile, suitable for stock engines and capable of supporting built applications. The system offers choices for throttle body integration, fitting the factory 90mm throttle body or providing an option for the enormous big bore super-mono blade throttle body. This larger throttle body is rated to flow 2750 CFM and includes factory-type electronics. For those seeking further enhancements, a carbon air tube upgrade is available, but it is specifically designed for the dual 71mm or elliptical throttle bodies and is not compatible with the stock throttle body. The kit is available in standard textured black, polished, or custom color finishes. The Whipple system features an oversized air-to-water intercooler for superior cooling and a unique front-feed W175ax (4.5L) integrated twin-screw supercharger. This unit achieves 99% volumetric efficiency and offers industry-leading power potential, being twice the size of the stock supercharger and optimized for higher boost levels. Its intercooled bypass system enhances acceleration and minimizes parasitic consumption during cruising for improved fuel economy. Please note that this kit does not include fuel injectors or programming.
