Best Camshaft Choices for Hemi Mds Delete: Competition Camshafts from Johnson and Ams

by

The HEMI engine has become a popular choice among performance enthusiasts, especially those looking to enhance their vehicle’s power and efficiency. One modification that many consider is the MDS (Multi-Displacement System) delete, which allows the engine to operate on all cylinders at all times. This modification often goes hand-in-hand with upgrading the camshaft to maximize performance. In this article, we will explore the best camshaft choices for HEMI MDS delete, focusing on competition camshafts from Johnson and AMS.

Understanding HEMI MDS Delete

The MDS system is designed to improve fuel efficiency by deactivating half of the engine’s cylinders during light-load conditions. While this can be beneficial for everyday driving, many performance enthusiasts prefer to disable this feature to achieve greater power and torque. The MDS delete allows for more consistent engine performance, especially in high-performance applications.

Why Upgrade Your Camshaft?

Upgrading the camshaft is one of the most effective ways to increase horsepower and torque in any engine. A performance camshaft can improve airflow, enhance throttle response, and provide a more aggressive engine note. When combined with an MDS delete, a new camshaft can significantly improve overall engine performance.
