by

The 5.7 HEMI engine has become a popular choice among automotive enthusiasts looking to enhance performance. To maximize the potential of your 5.7 HEMI power build, it’s essential to choose the right supporting modifications. This article will explore some of the best supporting mods, including ARH headers, Mopar Stage 2 cam, and Fast fuel rails.

Why Supporting Mods Matter

Supporting mods are critical in ensuring that your engine runs efficiently and effectively. These modifications help improve airflow, increase power output, and enhance overall engine performance. By investing in quality supporting mods, you can achieve a well-rounded power build that delivers impressive results on the road or track.

ARH Headers

American Racing Headers (ARH) is known for producing high-quality exhaust headers that significantly enhance performance. Upgrading to ARH headers can provide several benefits for your 5.7 HEMI build.

  • Improved Exhaust Flow: ARH headers are designed to optimize exhaust flow, reducing back pressure and allowing the engine to breathe better.
  • Increased Horsepower: With better exhaust flow, you can expect a noticeable increase in horsepower and torque.
  • Durable Construction: Made from high-quality materials, ARH headers are built to withstand high temperatures and resist corrosion.
  • Custom Fit: These headers are designed to fit perfectly on your 5.7 HEMI, making installation straightforward.

Installation Tips for ARH Headers

Installing ARH headers requires some mechanical expertise. Here are a few tips to ensure a successful installation:

  • Ensure the engine is cool before starting the installation.
  • Use new gaskets to prevent exhaust leaks.
  • Consider using a lift for easier access to the undercarriage.
  • Follow the manufacturer’s instructions closely for proper installation.

Mopar Stage 2 Cam

The Mopar Stage 2 cam is another excellent supporting mod for your 5.7 HEMI power build. This camshaft upgrade is designed to enhance the engine’s performance characteristics significantly.

  • Increased Lift and Duration: The Stage 2 cam offers higher lift and longer duration, which helps improve airflow into the engine.
  • Better Throttle Response: This camshaft upgrade enhances throttle response, making your vehicle feel more responsive.
  • Optimized Power Band: The Stage 2 cam is designed to optimize the power band, allowing for better performance at higher RPMs.
  • Improved Sound: Upgrading to a performance cam can give your engine a more aggressive sound that enthusiasts love.

Installation Considerations for the Mopar Stage 2 Cam

Installing a camshaft is a more complex modification that may require professional assistance. Here are some considerations:

  • Ensure you have the necessary tools and equipment for the installation.
  • Consider upgrading valve springs and pushrods for optimal performance.
  • Re-tune the engine after installation to maximize the benefits of the cam upgrade.
  • Be prepared for potential changes in idle quality and drivability.

Fast Fuel Rails

Fast fuel rails are an essential component for those looking to increase fuel delivery to their 5.7 HEMI engine. Upgrading to Fast fuel rails can provide several advantages.

  • Increased Fuel Flow: Fast fuel rails are designed to provide a higher flow rate, ensuring your engine receives the fuel it needs for optimal performance.
  • Improved Fuel Distribution: These rails help distribute fuel evenly across all cylinders, promoting better combustion and efficiency.
  • Compatibility: Fast fuel rails are compatible with various fuel injectors, allowing for customization based on your specific build.
  • Easy Installation: Designed for a straightforward installation process, Fast fuel rails can be added without extensive modifications.

Installing Fast Fuel Rails

Installing Fast fuel rails is relatively simple, but here are some tips to ensure a smooth process:

  • Relieve fuel pressure before starting the installation.
  • Use new O-rings to prevent leaks.
  • Double-check all connections after installation to ensure there are no leaks.
  • Consider re-tuning the engine to optimize fuel delivery and performance.

Conclusion

Upgrading your 5.7 HEMI engine with supporting mods like ARH headers, Mopar Stage 2 cam, and Fast fuel rails can significantly enhance performance. These modifications work together to optimize airflow, increase power, and improve overall engine efficiency. When planning your power build, consider these essential supporting mods to achieve the best results.
