Widow’s Extreme Machines offers a variety of ProCharger systems to bring your relatively stock power plant to competitive levels, or dominate the track and street with an all out ProCharger engine package!

The ULTIMATE Power Adder®
When it comes to force-air induction system for the modern HEMI engines, no one offers more advanced, powerful or reliable intercooled supercharger systems. ProCharger’s industry-leading systems allow owners to bolt on 130+ HP to an otherwise stock 5.7L HEMI, with ProCharged 6.1L HEMI engines gaining 160+ HP.

Engine-Friendly, Safe Boost Levels
With ongoing advancements in fuel injection and electronic engine management systems, intercooled centrifugal supercharging has proven to be the most engine friendly and easily installed type of forced air induction. Thanks to the highly efficient supercharger and intercooler design, ProCharger makes more power with less boost and heat, further improving engine reliability and your peace-of-mind. Requiring no internal engine modifications, ProCharged HEMI owners experience pure driving enjoyment with incredible power gains from a supercharger and the best engine reliability in the industry.

ProCharger System Choices
ProCharger specializes in high-efficiency, patented and proven centrifugal supercharger technology. So when it comes to finding a supercharger system for your HEMI, ProCharger and your ProCharger dealer are your ultimate solution for virtually any engine combination. ProCharger offers more supercharger, drive system, intercooler, bypass valve and fuel system upgrades than anyone. Once you’ve experienced the real-world power of a ProCharged HEMI, you’ll agree that ProCharger is the ultimate HEMI power adder.
Proven ProCharger HEMI Systems
ProCharger’s engineering and R&D teams went to great lengths to make sure your supercharged HEMI vehicle is everything you expect and more. Being the first supercharger manufacturer to safely and reliably supercharge late-model HEMI® engines, ProCharger is the undisputed leader. From the dyno to the street and track.

Easy to Own – Easy to Drive
With millions of boost-enhanced miles under their tires, ProCharged HEMI owners enjoy the best of both worlds: every-day reliability and driveability with incredible power that is just a toe-tip away. Owning and driving your ProCharged HEMI is an exercise in simplicity. With the patented and proven, self-contained ProCharger supercharger system design there is no need for special fuels. No need for additional engine or vehicle modifications. In fact, ProCharger systems and kits are designed to be installed on completely stock or modified HEMI engines. And yes, your HEMI-powered vehicle can be returned to stock condition.

Fuel-Mileage Friendly
Beyond overall power and performance, centrifugal superchargers are also the most fuel efficient form of high performance. Rising fuel costs and CAFE restrictions have prompted performance enthusiasts to think about fuel economy along with horsepower. It’s no secret that ProCharger systems not only produce the big power numbers we all crave, but under normal operating conditions, owners report very little effect on fuel mileage and in some cases, actually improved fuel economy.

100% Complete Systems
ProCharger EFI HEMI systems are 100 percent complete – nothing else to purchase. Late-model HEMI supercharger kits come with all the components needed for an attractive, OEM-quality installation. ProCharger’s engineers went to great lengths to make the system appear as close to original equipment as possible. Another benefit is its ease of installation – install it yourself or have your ProCharger dealer install it for you. The choice is yours.
