Building a Daily-driver Hemi Mds Delete: Balancing Power, Reliability, and Cost with Arh Headers and Sct Tuner

by

Building a daily-driver HEMI MDS delete is an exciting project for automotive enthusiasts looking to enhance the performance and reliability of their vehicles. This article will explore how to balance power, reliability, and cost while utilizing ARH headers and an SCT tuner.

Understanding the HEMI MDS System

The HEMI MDS (Multi-Displacement System) is designed to improve fuel efficiency by deactivating half of the engine’s cylinders under light load conditions. While this system can save fuel, it may lead to reliability concerns and performance limitations for daily drivers.

Benefits of MDS Delete

Removing the MDS system can offer several advantages:

  • Improved Reliability: Eliminating the MDS reduces the risk of mechanical failure associated with the system’s complexity.
  • Enhanced Performance: A full-time V8 operation provides consistent power delivery and throttle response.
  • Simplified Tuning: Tuning becomes more straightforward without the MDS parameters affecting performance maps.

Choosing the Right Components

To achieve a successful HEMI MDS delete, selecting the right components is crucial. The two primary components to consider are ARH headers and an SCT tuner.

ARH Headers

American Racing Headers (ARH) are known for their quality and performance. Here’s why they are a great choice:

  • Increased Exhaust Flow: ARH headers improve exhaust flow, leading to better engine performance and efficiency.
  • Durable Construction: Made from high-quality materials, ARH headers are built to withstand the rigors of daily driving.
  • Easy Installation: Designed for a direct fit, ARH headers simplify the installation process, making them user-friendly.

SCT Tuner

The SCT tuner is an essential tool for optimizing your engine’s performance after the MDS delete. Here are its key benefits:

  • Custom Tuning Options: The SCT tuner allows for custom tuning, enabling you to maximize the performance of your HEMI.
  • Easy Data Monitoring: You can monitor critical engine parameters, ensuring everything operates within safe limits.
  • Multiple Tune Options: The SCT tuner provides various pre-loaded tunes, allowing you to switch between performance and economy settings.

Installation Process

Installing an MDS delete kit with ARH headers and an SCT tuner involves several steps. Here’s a general outline of the installation process:

  • Gather Tools and Materials: Ensure you have all necessary tools, including wrenches, sockets, and the MDS delete kit.
  • Remove Existing Headers: Disconnect and remove the factory headers, taking care to keep all gaskets and hardware.
  • Install ARH Headers: Fit the ARH headers into place, ensuring a secure and leak-free connection.
  • Install MDS Delete Kit: Follow the manufacturer’s instructions to install the MDS delete kit, ensuring proper alignment and fit.
  • Connect SCT Tuner: Plug in the SCT tuner and upload the appropriate tune for your setup.

Cost Considerations

While building a daily-driver HEMI MDS delete can enhance performance, it’s essential to consider the costs:

  • ARH Headers: Prices typically range from $800 to $1,200 depending on the model and finish.
  • SCT Tuner: Expect to spend around $400 to $600 for a quality SCT tuner.
  • MDS Delete Kit: These kits usually cost between $100 and $300.
  • Labor Costs: If you’re not installing the components yourself, factor in labor costs, which can vary widely.

Final Thoughts

Building a daily-driver HEMI MDS delete with ARH headers and an SCT tuner is a rewarding project that can significantly enhance your vehicle’s performance and reliability. By carefully balancing power, reliability, and cost, you can create a setup that meets your driving needs while enjoying the benefits of a more robust HEMI engine.
