Inspired by the 1970’s original, the new generation Dodge Challenger is a true, in-your-face retro coupe design that packs a serious, HEMI-powered performance punch – but not nearly as serious as a ProCharger supercharged and intercooled Challenger!

While the whole of the automotive performance world was swooning over the Challenger’s introduction, ProCharger engineers and system developers were already hard at work on supercharger systems that allow owners to take their Challenger’s performance to the next, tire-shredding level.

ProCharger Systems for the 6.4L HEMI-powered SRT-8 Challengers can add major horsepower to an otherwise stock engine. All ProCharger systems are designed for and provide outstanding everyday driveability and reliability.

ProCharger systems and kits for the 6.4L HEMI Challengers have been painstakingly designed to be installed onto completely stock or modified engines and require no major modifications to the vehicle’s components. Under the hood, the installed ProCharger looks like it could have come from the factory, while the large, front-mounted air-to-air intercooler lets everyone know, “this isn’t your average Challenger!”


Intercooled ProCharger Systems and Tuner Kits for 2014-12 6.4L SRT8 Challengers and Chargers offer a gain of 200+ horsepower with a conservative 7 psi.  This industry leading technology provides the coolest charge air temperatures, largest power gains and most repeatable performance available.  For those wanting to purchase a tuner kit and have custom tuning performed by a local dealer, the gain is 225+ HP with 8 psi.

ProCharger’s 6.4L/392 systems and tuner kits feature the industry standard P-1SC-1 ProCharger, with self-contained oiling, billet impeller and billet gear cases standard. This kit also features highly effective and reliable air-to-air intercooling, which combines with an advantaged mounting location and best in class supercharger efficiency to minimize heat production and heat transfer, and maximize reliable power gains.

Also available are tuner kits and systems for 2011+ 5.7L Challengers and Chargers, as well as the 2011+ 5.7L Ram truck.

ProCharger was the first manufacturer to offer complete supercharger systems for 6.1 and 5.7 HEMI’s, back in 2007. With continued industry and HEMI leadership, ProCharger was first once again for the 392, in early 2013.   ProCharger actually had fitment on 392 HEMI’s since early 2011, but we held off putting this system into volume production until a reliable, cost-effective solution was available for engine calibration. That solution became available in early 2013, and 2014-12 ProCharger systems for 5.7 and 6.4L HEMI’s feature Diablo handheld programmers.

For years, the ProCharger HO Intercooled Supercharger System has been delivering big power numbers to hundreds of HEMI customers, but now the time has come for the next evolution of ProCharger power–the Stage II Dedicated Drive System and tuner kit for 6.4L/392 HEMI’s! So if you are aching for 800, 900, 1000, even 1200+ HP from your HEMI-powered monster, we have your solution.

The ProCharger Stage II Supercharger offering features an all new 8-rib dedicated drive system and race intercooler upgrade for 6.4L and 5.7L (air-to-air race intercooler coming soon for 6.1L also). Why should this be music to your ears? Let us explain:

ProCharger HEMI 392 Stage 2 Supercharger System

ProCharger designed this dedicated 8-rib system to have maximum belt wrap in order to support the truly power hungry. The bracket system fits head units up to F-1A-94 without modifications to the car, which means no cutting or trimming with a blower that can support 1,200+ HP!

Even though this system is perfect for “race” applications, it can still be used with a P-1SC-1 at lower boost levels for mild street applications. The OEM-quality fit and finish is what you’d expect from the ProCharger engineering department, as illustrated in the image below.

In order to support the power levels made possible by the Stage II System, ProCharger now also offers a Race Intercooler option for both the 6.4L and 5.7L HEMI platforms (6.1L coming soon). Below is an image of this new huge intercooler mounted behind the factory bumper cover because, you guessed it, no trimming or cutting is required to fit this highly effective intercooler behind the bumper, thanks to a custom ProCharger design built just for this application. That’s great news for anyone who may want to return their car back to stock down the road.

This animation shows the two intercooler options available for the 2011+ 6.4L SRT Challenger. The HO intercooler features a high flow, top-to-bottom core design that maximizes available airflow through the car’s front fascia. However, for those pushing higher boost and horsepower levels, the Race Intercooler option with 970 cubic inch core is also available.

Stage II Intercooler = 423 cubic/inch Cooling Core
Race Intercooler = 970 cubic/inch Cooling Core
