Can a 6.4 Hemi be supercharged?
The 6.4 Hemi engine, known for its robust performance and reliability, is a popular choice among car enthusiasts and muscle car owners. But can this powerhouse of an engine be supercharged? The short answer is yes! Supercharging a 6.4 Hemi is not only possible but also a common modification for those looking to significantly boost horsepower and torque. In this article, we’ll explore the benefits, considerations, and steps involved in supercharging a 6.4 Hemi engine.
What Is a Supercharger and How Does It Work?
A supercharger is a forced induction system that compresses air flowing into the engine. By increasing the air density, the engine can burn more fuel, resulting in greater power output. Unlike a turbocharger, which relies on exhaust gases to spin a turbine, a supercharger is driven directly by the engine’s crankshaft, providing instant power delivery.
Why Supercharge a 6.4 Hemi?
The 6.4 Hemi engine, found in vehicles like the Dodge Charger, Challenger, and Jeep Grand Cherokee SRT, already delivers impressive performance. However, adding a supercharger can take it to the next level. Here are some key benefits:
- Increased Horsepower: A supercharger can boost the 6.4 Hemi’s horsepower by 100-200 HP or more, depending on the setup.
- Improved Torque: Supercharging enhances low-end torque, making acceleration quicker and more responsive.
- Enhanced Driving Experience: The added power transforms the vehicle into a high-performance machine, perfect for track days or spirited driving.
Considerations Before Supercharging
While supercharging a 6.4 Hemi is an exciting upgrade, there are several factors to consider before diving in:
- Engine Health: Ensure your engine is in good condition. A worn or poorly maintained engine may not handle the added stress of forced induction.
- Fuel Requirements: Supercharged engines often require higher-octane fuel to prevent knocking and ensure optimal performance.
- Cooling System: The added power generates more heat, so upgrading the cooling system may be necessary to prevent overheating.
- Cost: Supercharging is a significant investment, with kits and installation costs ranging from $5,000 to $10,000 or more.
Steps to Supercharge a 6.4 Hemi
If you’re ready to supercharge your 6.4 Hemi, here’s a general overview of the process:
- Choose a Supercharger Kit: Select a kit designed specifically for the 6.4 Hemi. Popular options include centrifugal, roots-style, and twin-screw superchargers.
- Prepare the Engine: Perform a thorough inspection and address any maintenance issues. Consider upgrading internal components like pistons and rods for added durability.
- Install the Supercharger: Follow the manufacturer’s instructions or have a professional mechanic handle the installation to ensure proper fitment and performance.
- Tune the Engine: After installation, the engine must be tuned to optimize performance and ensure reliability. This step is crucial for achieving the best results.
Conclusion
Supercharging a 6.4 Hemi is a fantastic way to unlock its full potential and elevate your driving experience. With the right preparation, components, and professional installation, you can enjoy a significant boost in power and performance. Whether you’re looking to dominate the track or simply enjoy a more thrilling ride, a supercharged 6.4 Hemi is sure to deliver.
Frequently Asked Questions
Can a stock 6.4 Hemi handle a supercharger?
While the 6.4L HEMI responds well to naturally aspirated modifications – including camshaft, cylinder head, and intake manifold upgrades — another popular option is forced induction. Supercharger kits are extremely popular for the 6.4L HEMI and come in many varieties from centrifugal to roots to twin-screws.
Can a 6.4 Hemi handle a supercharger?
In many cases, a supercharger can provide more performance than a stock 6.4L HEMI can reliably handle. Most 6.4L HEMI supercharger kits are designed to be plug-and-play modifications, meaning that they come with everything that you need to get up and running, including some upgraded engine components.

How much horsepower can you get out of a 6.4 HEMI?
410 horsepower
6.4 Hemi Performance
The 6.4 Hemi V8 engine is designed for powerful and efficient performance. In addition to its impressive 410 horsepower and 429 lb-ft of torque, the 6.4 Hemi also offers improved fuel economy over previous generations of the V8 engine.
Can you put a whipple supercharger on a 6.4 HEMI?
Unleash Pure Muscle Power with the All-New Gen 6 Whipple Supercharger System for Dodge Hemi 6.4L Engine! Since 1987, Whipple Superchargers™ has been at the forefront of twin-screw supercharging technology, setting the standard for performance and innovation.
What is the difference between a Whipple and a supercharger?
Efficiency and Power: Whipple Superchargers are generally regarded as more efficient and capable of producing higher power gains compared to Roush Superchargers. The twin-screw design of the Whipple allows for greater airflow and lower air temperatures, resulting in increased power output.
Can you put a Hellcat supercharger on a 6.4 HEMI?
CFR's conversion spacers allow for the Hellcat's perimeter bolt pattern to work on the naturally aspirated Hemi's centrally positioned intake manifold bolt holes (2011-up VVT-equipped 5.7-liter and 6.4-liter Eagle and Apache only).
How much HP can a 6.4 HEMI handle?
Nine hundred and fifty rear-wheel horsepower. "That's how far you can push a stock 6.4L Hemi block before you need to worry," says Dave Weber from Modern Muscle Xtreme (MMX).
How to get more power out of 6.4 Hemi?
Upgrading to larger Fuel Injectors is often needed to meet the demand of increased power. The factory fuel pump will become a limitation around 550 hp. So, plan on upgrading the Fuel Pump as well. Truck engines have a conservative tune from the factory.
Can a stock 6.4 HEMI handle boost?
The stock 6.4 HEMI can commonly handle boost pressures around 6 psi with some fuel system modifications, water-methane injection to keep the cylinders cool, and an accurate tune by someone knowledgeable of the intricacies of the 6.4 HEMI engine network of control modules.
