With the right modifications, including a supercharger, this engine can achieve impressive horsepower figures. In this article, we will explore how to build a 5.7 HEMI supercharged engine capable of producing over 550 horsepower using Edelbrock components.
Understanding the 5.7 HEMI Engine
The 5.7 HEMI engine, part of Chrysler’s HEMI family, is known for its distinctive hemispherical combustion chamber design. This design allows for better airflow and combustion efficiency, making it a solid foundation for performance upgrades.
Key Features of the 5.7 HEMI
- Hemispherical combustion chambers
- Variable valve timing (VVT)
- Modular design for easy upgrades
Choosing the Right Supercharger
To achieve over 550 horsepower, selecting the right supercharger is crucial. The Edelbrock supercharger system is a popular choice due to its reliability and performance.
Edelbrock Supercharger Benefits
- Intercooled design for improved efficiency
- Easy installation with a bolt-on design
- Proven performance gains
Building the Engine
Building a supercharged 5.7 HEMI involves several key steps, from selecting the right components to tuning the engine for optimal performance.
Essential Components
- Edelbrock supercharger kit
- High-performance fuel injectors
- Upgraded fuel pump
- Cold air intake system
- Performance exhaust system
Step-by-Step Build Process
Follow these steps to build your supercharged 5.7 HEMI:
- Remove the factory intake and exhaust systems.
- Install the Edelbrock supercharger kit according to the manufacturer’s instructions.
- Upgrade the fuel system by replacing injectors and the fuel pump.
- Add a cold air intake to improve airflow.
- Install a high-performance exhaust system to reduce back pressure.
- Reassemble the engine and perform necessary checks.
Tuning for Maximum Performance
After building the engine, tuning is essential to ensure it runs efficiently and achieves the desired horsepower. A professional tune can optimize fuel delivery and ignition timing.
Importance of Tuning
- Maximizes horsepower and torque
