The HEMI engine is renowned for its power and performance, but with the Multi-Displacement System (MDS) in place, some enthusiasts feel that it limits the engine’s full potential. A HEMI MDS delete custom build can unlock significant horsepower, especially when paired with an Edelbrock supercharger. In this article, we will explore how to achieve 550+ horsepower through this custom build.
Understanding HEMI MDS and Its Limitations
The Multi-Displacement System (MDS) is designed to improve fuel efficiency by deactivating half of the engine’s cylinders under light-load conditions. While this feature is beneficial for daily driving, it can hinder performance during high-demand situations.
Why Delete the MDS?
Removing the MDS can enhance throttle response and overall power output. Here are some reasons why car enthusiasts opt for an MDS delete:
- Improved throttle response
- Increased horsepower and torque
- Enhanced engine sound
- Better performance in high-demand situations
Components Needed for the Build
To achieve the desired horsepower with an Edelbrock supercharger, several components are essential. Below is a list of key components needed for the HEMI MDS delete custom build:
- Edelbrock Supercharger Kit
- MDS Delete Kit
- High-Performance Fuel Injectors
- Upgraded Fuel Pump
- Cold Air Intake System
- Custom Tuning Software
- High-Performance Exhaust System
Step-by-Step Build Process
Building a custom HEMI MDS delete engine with an Edelbrock supercharger involves several steps. Below is a detailed guide to help you through the process:
1. Remove the MDS Components
The first step is to remove the MDS components from the engine. This includes the MDS solenoids and the necessary wiring. Ensure that you have the MDS delete kit ready to replace these components.
2. Install the MDS Delete Kit
Once the MDS components are removed, install the MDS delete kit. This kit will typically include block-off plates and necessary gaskets to ensure a proper seal.
3. Install the Edelbrock Supercharger
Follow the instructions provided with the Edelbrock supercharger kit for installation. This usually involves mounting the supercharger, connecting the intake, and ensuring all hoses are properly fitted.
4. Upgrade the Fuel System
With the increased horsepower, it is crucial to upgrade the fuel system. Install high-performance fuel injectors and an upgraded fuel pump to accommodate the additional fuel demands of the supercharged engine.
5. Install a Cold Air Intake
A cold air intake system will help the engine breathe better and improve performance. Ensure that the intake is compatible with the Edelbrock supercharger.
6. Tune the Engine
After all components are installed, it’s time to tune the engine. Use custom tuning software to adjust the engine parameters for optimal performance. This step is crucial for achieving the desired horsepower.
Expected Performance Gains
With the MDS delete and the installation of the Edelbrock supercharger, you can expect significant performance gains. Here are some expected outcomes:
- Horsepower: 550+ HP
- Torque: Increased torque throughout the power band
- Improved acceleration and throttle response
- Enhanced engine sound and performance
Conclusion
A HEMI MDS delete custom build paired with an Edelbrock supercharger can unlock the full potential of your engine, achieving over 550 horsepower. This build not only enhances performance but also provides a more engaging driving experience. Whether you’re a seasoned enthusiast or a newcomer to the world of performance modifications, this guide will help you on your journey to a powerful HEMI engine.
