How to Reach 550+ Horsepower with a 5.7 Hemi Turbo Kit Using Comp Cams and Arp Fasteners

by

The 5.7 HEMI engine has earned a reputation for being a powerful platform for performance enthusiasts. With the right modifications, you can push this engine to reach 550+ horsepower. In this article, we will explore how to achieve this using a turbo kit, Comp Cams, and ARP fasteners.

Understanding the 5.7 HEMI Engine

The 5.7 HEMI engine is a V8 powerhouse known for its robust design and impressive performance capabilities. Its hemispherical combustion chamber allows for better airflow, which is essential when adding forced induction.

Choosing the Right Turbo Kit

To reach 550+ horsepower, selecting an appropriate turbo kit is crucial. Here are some key considerations:

  • Turbo Size: A larger turbo can provide more power but may cause lag. Balance is key.
  • Intercooler: A high-quality intercooler is essential for reducing intake temperatures.
  • Exhaust Manifold: Look for a manifold designed for your specific turbo kit for optimal performance.

Several turbo kits are popular among HEMI enthusiasts:

  • Hellion Twin Turbo Kit
  • Procharger Supercharger Kit
  • Vortech Supercharger Kit

Upgrading with Comp Cams

Comp Cams offers a range of camshafts that can significantly enhance your engine’s performance. Upgrading your camshaft can improve airflow and increase horsepower.

Choosing the Right Camshaft

When selecting a camshaft, consider the following:

  • Lift: Higher lift can lead to increased power but may require additional modifications.
  • Duration: Longer duration can improve performance at higher RPMs.
  • Overlap: Proper overlap can enhance performance but may affect idle quality.

Some popular Comp Cams for the 5.7 HEMI include:

  • Comp Cams XFI RPM Series
  • Comp Cams NSR Series
  • Comp Cams Stage 2 HEMI Cam

Utilizing ARP Fasteners

When modifying your engine, using high-quality fasteners is essential. ARP fasteners are known for their strength and reliability, making them a popular choice for performance builds.

Benefits of ARP Fasteners

Here are some benefits of using ARP fasteners:

  • Increased Strength: ARP fasteners are designed to withstand higher stress levels.
  • Durability: They resist stretching and fatigue, ensuring long-term reliability.
  • Precision Engineering: Each fastener is manufactured to exact specifications for perfect fitment.

For your 5.7 HEMI build, consider these ARP fasteners:

  • ARP Cylinder Head Studs
  • ARP Main Studs
  • ARP Connecting Rod Bolts

Putting It All Together

Once you have selected your turbo kit, camshaft, and fasteners, it’s time to put everything together. Here are some tips for a successful installation:

  • Follow Instructions: Always adhere to the manufacturer’s installation instructions.
  • Use Quality Tools: Invest in good tools to ensure precision and prevent damage.
  • Check Clearances: Ensure that all components fit properly and do not interfere with each other.

Tuning Your HEMI for Maximum Performance

After installation, tuning is critical to achieving your horsepower goals. A proper tune will optimize fuel delivery and ignition timing for the best performance.

Tuning Options

  • Standalone ECU: Consider a standalone engine management system for maximum control.
  • Custom Tune: Work with a professional tuner to create a custom tune for your setup.
  • Dyno Testing: Use a dyno to measure your horsepower and make necessary adjustments.

Conclusion

Reaching 550+ horsepower with a 5.7 HEMI engine is an achievable goal with the right turbo kit, Comp Cams, and ARP fasteners. By carefully selecting components and ensuring proper installation and tuning, you can unlock the full potential of your HEMI engine. Happy tuning!
