Can a 6.4 Hemi be supercharged?
Yes, the 6.4-liter Hemi V8 engine found in many high-performance Dodge and Jeep vehicles can be supercharged. Supercharging the 6.4 Hemi can significantly increase its power output, making it an attractive option for enthusiasts looking to boost the performance of their vehicles.
Understanding the 6.4 Hemi Engine
The 6.4-liter Hemi V8 engine, also known as the 392 Hemi, is a powerful and versatile engine found in various Dodge and Jeep models, including the Dodge Challenger, Charger, and Durango, as well as the Jeep Grand Cherokee. This engine is known for its impressive power and torque, delivering up to 485 horsepower and 475 lb-ft of torque in its stock configuration.
Supercharging the 6.4 Hemi
Supercharging the 6.4 Hemi engine involves adding a forced induction system, typically a supercharger, to the engine. This process increases the amount of air and fuel that can be packed into the engine's cylinders, resulting in a significant boost in power output. Supercharging the 6.4 Hemi can increase its power output by as much as 30-40%, with some high-performance setups capable of producing over 700 horsepower.
Benefits and Considerations
Supercharging the 6.4 Hemi offers several benefits, including:
- Increased power and acceleration: The added boost from the supercharger can dramatically improve the engine's performance, making the vehicle more responsive and exciting to drive.
- Improved towing and hauling capabilities: The extra power can be particularly useful for vehicles that are used for towing or hauling heavy loads.
- Enhanced driving experience: The combination of the Hemi's inherent power and the added boost from the supercharger can provide an exhilarating and engaging driving experience.
However, there are also some considerations to keep in mind when supercharging the 6.4 Hemi:
- Increased fuel consumption: The added power from the supercharger will result in higher fuel consumption, which may be a concern for some owners.
- Potential reliability issues: Supercharging can put additional stress on the engine and other components, potentially leading to reliability concerns if not properly installed and maintained.
- Cost: Supercharging the 6.4 Hemi can be an expensive process, with the cost of the supercharger, installation, and any necessary upgrades to other components.
Overall, the 6.4 Hemi can be successfully supercharged, providing a significant boost in power and performance. However, it's important to carefully consider the benefits and drawbacks before undertaking such a modification.
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 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.
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).
Can a 6.4 Hemi handle a supercharger?

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.
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 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.
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 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.
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).
