Best Camshaft and Valve Spring Combinations for Hemi Mds Delete Power Goals

by

The HEMI engine is renowned for its power and performance, particularly when equipped with the Multiple Displacement System (MDS). However, many enthusiasts choose to delete the MDS for various reasons, including increased power and improved throttle response. In this article, we will explore the best camshaft and valve spring combinations to maximize power goals for HEMI MDS delete setups.

Understanding HEMI MDS Delete

The MDS technology in HEMI engines allows for improved fuel efficiency by deactivating half of the cylinders under light load conditions. While this technology has its benefits, many performance enthusiasts prefer a full-time active engine for better power delivery. Deleting the MDS can lead to significant performance gains, but it requires careful selection of camshafts and valve springs to ensure optimal performance.

Choosing the Right Camshaft

When selecting a camshaft for your HEMI MDS delete, consider the following factors:

  • Lift: Higher lift can increase airflow, but be cautious of clearance issues.
  • Duration: Longer duration can improve top-end power but may affect idle quality.
  • Overlap: Consider the amount of overlap for performance versus drivability.

Here are some popular camshaft options for HEMI MDS delete builds:

  • Comp Cams Stage 2: Offers a good balance of performance and daily drivability.
  • Mopar Performance Stage 1: Designed specifically for HEMI engines, providing a noticeable power increase.
  • Texas Speed Camshaft: Known for aggressive profiles that maximize horsepower.

Valve Spring Selection

Upgrading your valve springs is crucial when changing camshafts, as stock springs may not handle the increased lift and duration effectively. Proper valve spring selection will ensure that your engine maintains optimal performance and prevents valve float.

Key Considerations for Valve Springs

  • Spring Rate: Higher spring rates can handle increased lift but may affect valve train wear.
  • Installed Height: Ensure compatibility with your camshaft specifications.
  • Material: Look for high-quality materials that can withstand the rigors of performance applications.

Here are some recommended valve springs for HEMI MDS delete builds:

  • Comp Cams Beehive Springs: Ideal for high lift applications and improved performance.
  • Mopar Performance Valve Springs: Designed for use with Mopar camshafts, providing reliable performance.
  • Manley Performance Springs: Known for their durability and ability to handle aggressive cam profiles.

Combining Camshaft and Valve Springs

To achieve the best performance from your HEMI MDS delete, it’s essential to pair the right camshaft with compatible valve springs. Here are some effective combinations:

  • Comp Cams Stage 2 with Comp Beehive Springs: Excellent for street and strip applications.
  • Mopar Performance Stage 1 with Mopar Valve Springs: A reliable combo for daily drivers.
  • Texas Speed Camshaft with Manley Springs: Perfect for high-performance builds aiming for maximum horsepower.

Conclusion

Choosing the right camshaft and valve spring combination for your HEMI MDS delete can significantly impact your vehicle’s performance. By understanding the options available and carefully selecting the components, you can achieve your power goals while maintaining drivability. Always consider your specific performance needs and consult with experts if needed to ensure the best results.
