The 5.7 HEMI engine has earned a reputation for its power and performance. However, many enthusiasts are always looking for ways to enhance its capabilities. One of the most effective methods is by upgrading to Borla headers and a high-performance camshaft. This guide will walk you through the process of doubling your 5.7 HEMI’s power using these modifications.
Understanding the Basics of the 5.7 HEMI
The 5.7 HEMI engine is a V8 powerhouse known for its unique hemispherical combustion chamber design. This design allows for better airflow and combustion efficiency, making it a popular choice among car enthusiasts. However, to truly unlock its potential, performance upgrades are essential.
Why Upgrade to Borla Headers?
Borla headers are designed to improve exhaust flow, which can significantly enhance engine performance. Here are some reasons to consider Borla headers:
- Increased Horsepower: By reducing back pressure, Borla headers can increase horsepower by allowing exhaust gases to exit more freely.
- Improved Sound: Borla headers provide a deeper, more aggressive exhaust note that many enthusiasts love.
- Durability: Made from high-quality materials, Borla headers are designed to withstand high temperatures and resist corrosion.
Choosing the Right Camshaft
The camshaft plays a crucial role in determining the engine’s performance characteristics. Upgrading to a higher-performance camshaft can lead to significant improvements in horsepower and torque. Here are some factors to consider when selecting a camshaft:
- Lift and Duration: Higher lift and longer duration can improve airflow, but may require additional modifications.
- Compatibility: Ensure the camshaft is compatible with your engine and other modifications.
- Intended Use: Choose a camshaft that matches your performance goals, whether for street use or racing.
Installation Process
Installing Borla headers and a new camshaft requires mechanical skill and the right tools. Here’s a step-by-step guide to help you through the installation process:
Tools and Materials Needed
- Socket set
- Wrenches
- Torque wrench
- Jack and jack stands
- New camshaft
- Borla headers
- Gaskets and hardware
Step-by-Step Installation
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.
- Remove the Old Exhaust Manifold: Carefully unbolt the old exhaust manifold and remove it from the engine.
- Install Borla Headers: Position the Borla headers onto the engine, ensuring proper alignment. Use new gaskets and bolts for a secure fit.
- Replace the Camshaft: Remove the timing cover and timing chain/belt. Unbolt the old camshaft and replace it with the new one, following the manufacturer’s instructions.
- Reassemble: Reinstall the timing cover and other components. Ensure all bolts are torqued to the manufacturer’s specifications.
- Reconnect the Battery: Once everything is reassembled, reconnect the battery and start the vehicle to check for leaks and proper operation.
Tuning Your Engine
After installing the new headers and camshaft, tuning your engine is crucial for maximizing performance. A proper tune can optimize fuel delivery and ignition timing, ensuring your engine runs smoothly and efficiently.
Benefits of Engine Tuning
- Improved Performance: Tuning can unlock additional horsepower and torque.
- Better Fuel Economy: A well-tuned engine can improve fuel efficiency.
- Enhanced Reliability: Proper tuning can reduce engine wear and prolong lifespan.
Conclusion
Upgrading your 5.7 HEMI with Borla headers and a high-performance camshaft is an excellent way to significantly boost its power. With the right tools, knowledge, and a bit of mechanical skill, you can achieve impressive performance gains. Remember to tune your engine after installation to fully realize the benefits of your upgrades. Enjoy the enhanced performance and the thrill of driving your upgraded 5.7 HEMI!
