SHOULD YOU SUPERCHARGE YOUR HEMI?

HEMI SUPERCHARGER KITS BY PROCHARGER MAKE BIG POWER

We’ve read your comments. We’ve taken your calls. It’s time to let the rubber hit the road and explain why these Gen III HEMI’s (and V6’s) are incredibly fun, reliable, and all-out horsepower monsters! Supercharging your HEMI-powered vehicle is one of the most exciting ways to unlock more horsepower and performance. But naturally, many drivers ask: Is it safe? The short answer: Yes, it is—especially when you go with ProCharger.

OVER 20 YEARS OF HEMI SUPERCHARGING

With over 20 years of experience supercharging HEMI engines and being the first supercharger manufacturer to launch a system specifically for the modern 6.4L 392 Gen III HEMI, ProCharger has built a reputation for safe, reliable, and repeatable power.

HEMI AND PROCHARGER: A MARRIAGE MADE IN HEAVEN!

ProChargers and Dodge/Chrysler hemispherical engines have always worked well together. Today’s modern Gen III HEMI engines are masterpieces of engineering that make great power from the factory, and amazing power that will knock your socks off when paired with a ProCharger supercharger. These engines like a high-efficiency supercharger with a good thermal profile, as well as a highly effective intercooler, for cool charge air and engine friendly boost. To ensure reliable power gains, a ProCharger system helps keep the engine operating cooler and further from the detonation threshold, compared to a top-mounted PD blower or exhaust-mounted turbocharger. ProCharger also produces the most power per psi of boost, allowing a conservative and safe boost level. Additionally, ProCharger produces the best drivability and overall power curve for HEMIs, given the strong torque and quick throttle response of these engines.

THE MYTH DISPELLED

We often hear comments, mostly on social media, that Gen III HEMI engines are brittle and susceptible to breakage under boost. That’s just an oft-repeated “old wives tale.” ProCharger has had great success boosting the various generations of HEMI engines. The key is managing boost pressure and charge air temps, running high-quality fuel (91 or 93 octane minimum), and using an experienced HEMI tuner if your build requires it. Stick to those guidelines, and your supercharged HEMI will deliver reliable power for the long haul.

“Cooler air makes more power-period. With the ProCharger kit, those numbers jumped to 616.86 RWHP [otherwise stock 392 HEMI, automatic transmission, race intercooler] … and with just 7-pounds of boost.” – Mopar Muscle

HOW MUCH HP CAN A PROCHARGER SUPERCHARGED HEMI MAKE?

ProCharger superchargers for HEMI engines lead the way with power gains. For the 6.4L, you can get over 215 HP on standard premium pump gas, putting the power output at more than 700HP. This rivals the Dodge Hellcat at a fraction of the price, with only 7 psi of highly-efficient, engine-friendly, intercooled boost. Plus, the robust ProCharger bracket system works with the 392’s electric steering, and our air-to-air intercooler is super easy to install.

6.4L = 215+ HP Gain
5.7L = 160+ HP Gain
3.6L = 120+ HP Gain

☑️ 7 PSI of boost
☑️ Engine safe tune
☑️ Bolt-On Installation
☑️ Made in America

Intercooled ProCharger Systems provide the coolest charge air temperatures, the largest power gains, and the most repeatable performance. ProCharger’s 6.4L, 6.1L, 5.7L and 3.6L Systems and Tuner Kits feature the industry-standard P-1SC-1 ProCharger, with self-contained oiling, billet impeller, and billet gear case. Our highly effective and reliable intercooling system maximizing our reliable power gains.

WHICH HEMI DO YOU WANT TO SUPERCHARGE?

FREQUENTLY ASKED QUESTIONS: IS ADDING BOOST TO A HEMI SAFE?

Q: Can my stock HEMI engine handle boost?
A: Yes. Stock Gen III HEMI engines, especially the 5.7L and 6.4L, are built strong and can handle moderate boost levels with no problem—especially when using a well-engineered, intercooled system like ProCharger’s.

Q: What makes ProCharger safer than other superchargers?
A: ProCharger’s centrifugal design runs cooler, makes power more progressively (reducing stress on engine components), and includes an air-to-air intercooler to reduce detonation risk. Plus, no need to tap into the engine’s oil system—our units are self-contained.

Q: Has ProCharger been boosting HEMIs longer than anyone else?
A: Absolutely. ProCharger was the first supercharger manufacturer to release a kit for late-model HEMIs, and we’ve spent over two decades dialing in these platforms for max performance and long-term reliability.

Q: Will a ProCharger shorten my engine’s life?
A: No—our systems are designed for reliability. In fact, many customers have put well over 100,000–200,000 miles on ProCharged HEMI engines without issue, thanks to proper tuning and high-quality engineering.
