Best Supporting Mods for 500+ Hp Hemi Mds Delete Builds: Camshaft, Headers, and Ecu Tunes

by

Building a high-performance HEMI engine capable of producing over 500 horsepower requires careful consideration of supporting modifications. This article will focus on the best supporting mods for HEMI MDS delete builds, specifically camshafts, headers, and ECU tunes. Each of these components plays a crucial role in maximizing performance and ensuring that your engine runs smoothly and efficiently.

Understanding HEMI MDS Delete Builds

The HEMI engine’s Multi-Displacement System (MDS) is designed to improve fuel efficiency by deactivating half of the engine’s cylinders during light-load conditions. While this feature is beneficial for daily driving, it can hinder performance in high-power builds. Deleting the MDS allows for better airflow and more consistent power delivery, making it ideal for performance enthusiasts.

Best Supporting Mods for HEMI MDS Delete Builds

1. Camshaft Upgrades

Upgrading the camshaft is one of the most effective ways to increase horsepower and torque in a HEMI engine. A performance camshaft can improve airflow and enhance the engine’s power band. Here are some popular camshaft options:

  • Comp Cams Stage 2 Camshaft: Offers a good balance of performance and drivability.
  • Hemi Fever Camshaft: Designed for optimal performance in MDS delete applications.
  • Texas Speed Camshaft: Known for aggressive profiles that maximize horsepower.

2. Performance Headers

Headers are essential for improving exhaust flow and reducing back pressure, which can significantly enhance performance. When selecting headers for your HEMI, consider the following options:

  • American Racing Headers: High-quality headers that provide excellent fitment and performance.
  • JBA Headers: Known for their durable construction and improved exhaust flow.
  • Hooker Headers: Offer a variety of designs for different performance needs.

3. ECU Tunes

Tuning the ECU is critical for maximizing the performance of your HEMI MDS delete build. A proper tune will optimize fuel maps, ignition timing, and other parameters to ensure your engine runs efficiently. Consider these tuning options:

  • DiabloSport Trinity T2: A popular choice for custom tuning and performance monitoring.
  • HP Tuners: Offers extensive tuning capabilities for serious enthusiasts.
  • SCT Performance: Provides reliable tunes for various HEMI applications.

Combining Mods for Maximum Performance

When building a HEMI MDS delete engine, it’s essential to combine these mods effectively. The right camshaft paired with high-flow headers and a custom ECU tune can yield impressive results. Here’s how to approach the combination:

  • Choose a camshaft that matches your desired power band.
  • Select headers that complement your camshaft choice.
  • Ensure your ECU tune is tailored to your specific setup for optimal performance.

Conclusion

For those looking to build a HEMI engine capable of over 500 horsepower, selecting the right supporting mods is crucial. Camshaft upgrades, performance headers, and ECU tunes all play significant roles in achieving your power goals. By carefully considering each component and how they work together, you can create a powerful and efficient HEMI MDS delete build that meets your performance expectations.
