Hemi Mds Delete for 600+ Hp: Best Camshaft and Tune Combos for Max Power

by

The HEMI engine has long been a favorite among performance enthusiasts, especially those looking to push their horsepower numbers beyond the 600 HP mark. One of the most effective ways to achieve this is through the HEMI MDS (Multi-Displacement System) delete. This modification not only enhances performance but also allows for a more aggressive camshaft and tuning combination. In this article, we will explore the best camshaft and tune combos to maximize power after performing an MDS delete.

Understanding HEMI MDS Delete

The HEMI MDS is designed to improve fuel efficiency by deactivating half of the engine’s cylinders under light load conditions. While this system is beneficial for everyday driving, it can hinder performance when pushing for higher horsepower. By removing the MDS, enthusiasts can unlock the full potential of their HEMI engines.

Benefits of MDS Delete

Performing an MDS delete on your HEMI engine provides several advantages:

  • Increased Power: Removing the MDS allows for a more aggressive camshaft profile, leading to significant power gains.
  • Improved Throttle Response: With all cylinders firing consistently, throttle response becomes more immediate and engaging.
  • Better Engine Sound: The engine produces a more robust sound, enhancing the driving experience.
  • Enhanced Reliability: Eliminating the MDS reduces the complexity of the engine, potentially increasing reliability.

Choosing the Right Camshaft

Selecting the right camshaft is crucial for maximizing power after an MDS delete. Here are some top camshaft options for HEMI engines:

  • Comp Cams XFI 274: This camshaft offers a great balance of power and drivability, making it a popular choice for street and strip applications.
  • Hughes Engines 250/260: Known for its aggressive profile, this camshaft is designed for serious power and performance.
  • Texas Speed 6.1L Cam: Ideal for those looking to push the limits, this camshaft provides excellent high RPM performance.
  • Mopar Performance Stage 1: A reliable option that enhances performance while maintaining good drivability.

Tuning for Maximum Performance

After selecting the right camshaft, proper tuning is essential to ensure optimal performance. Here are some tuning options to consider:

  • HP Tuners: A popular choice among enthusiasts, HP Tuners provides advanced tuning capabilities for HEMI engines.
  • DiabloSport Trinity 2: This device allows for easy tuning and monitoring of engine parameters, making it user-friendly.
  • EFI Live: Known for its flexibility, EFI Live is perfect for those who want to fine-tune every aspect of their engine’s performance.
  • Custom Tuning: For the best results, consider hiring a professional tuner who specializes in HEMI engines.

Supporting Mods for Increased Power

In addition to the MDS delete, camshaft, and tuning, several supporting modifications can further enhance your HEMI’s performance:

  • High-Performance Headers: Upgrading to headers can improve exhaust flow, leading to better performance.
  • Cold Air Intake: A cold air intake system can help your engine breathe better, resulting in increased horsepower.
  • High-Flow Fuel Injectors: To support higher horsepower, consider upgrading to larger fuel injectors.
  • Performance Exhaust System: An aftermarket exhaust system can reduce back pressure and improve overall performance.

Final Thoughts

Achieving over 600 HP in a HEMI engine is an exciting challenge that requires careful planning and execution. By performing an MDS delete and selecting the right camshaft and tuning, along with supporting modifications, you can unlock the full potential of your HEMI. Always remember to consult with professionals and conduct proper research to ensure the best outcomes for your performance goals.
