The 5.7 HEMI engine is a popular choice among performance enthusiasts looking to enhance their vehicle’s power and efficiency. One of the most effective ways to achieve this is through forced induction. In this article, we will explore key upgrades for your 5.7 HEMI, focusing on intercoolers, exhaust systems, and boost controllers.
Understanding Forced Induction
Forced induction is a method of increasing an engine’s power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in increased horsepower and torque. The two most common types of forced induction are superchargers and turbochargers.
Benefits of Upgrading to Forced Induction
- Significant power gains
- Improved throttle response
- Better fuel efficiency
- Enhanced overall driving experience
Choosing the Right Intercooler
An intercooler plays a crucial role in forced induction systems by cooling the air entering the engine. Cooler air is denser, allowing for more oxygen to enter the combustion chamber. Here are some factors to consider when choosing an intercooler:
- Size: A larger intercooler can provide better cooling but may require modifications to fit.
- Type: Air-to-air intercoolers are common, but air-to-water intercoolers can offer superior cooling performance.
- Material: Look for intercoolers made from aluminum for better heat dissipation and durability.
Popular Intercooler Options for 5.7 HEMI
- Bell Intercoolers
- JMB Performance Intercoolers
- HPS Performance Intercoolers
Upgrading the Exhaust System
Upgrading your exhaust system is essential when adding forced induction to your 5.7 HEMI. A high-performance exhaust system can help reduce back pressure, allowing your engine to breathe more freely. Here are some key components to consider:
- Headers: Long-tube headers can improve exhaust flow, resulting in better performance.
- Cat-back Systems: A cat-back exhaust system will enhance sound and performance.
- High-Flow Catalytic Converters: These can reduce restrictions in the exhaust system.

- Flowmaster
- Borla
Boost Controllers: Managing Your Power
A boost controller is an essential component for managing the amount of boost pressure produced by your forced induction system. Proper management ensures that your engine runs efficiently and safely. There are two main types of boost controllers:
- Manual Boost Controllers: These allow for simple adjustments to boost pressure but require more tuning knowledge.
- Electronic Boost Controllers: These offer more precise control and can be adjusted on the fly.

Final Considerations
When upgrading your 5.7 HEMI for forced induction, it’s essential to consider the overall balance of your vehicle’s performance. Ensure that your engine, transmission, and drivetrain can handle the increased power. Additionally, proper tuning is crucial to maximize performance and maintain reliability.
By investing in quality intercoolers, exhaust systems, and boost controllers, you can significantly enhance your 5.7 HEMI’s performance and driving experience. Always consult with a professional or do thorough research to ensure that your upgrades are compatible and effective.
