The HRT Camshaft Series uses the newest and most advanced lobe designs from COMP Cams in order to produce some of the highest average power and torque increases available for turbo and supercharged engines. The “Low Shock Technology” features lobe profiles designed to maximize horsepower while improving stability at higher RPM. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. These new HRT Camshafts receive the Micro Surface Enhancement (MSE) finishing process as a standard feature, which increases strength and performance by reducing surface peak roughness and provides a 250% improvement in the effective load bearing area, allowing for much higher loads.Organized into stages, these new options range from mild street up to heavily modified race-oriented builds. All HRT Turbo & Supercharger Camshafts require a COMP Cams DOD Delete Kit and upgraded valve springs. Depending on application, 5.7L-6.4L w/ VVT 2009+ engines also require either a COMP Cams phaser limiter or lock kit.
Perfect Choice for 5.7L stock bottom end with responsive street type turbo systems. Excellent throttle response and great power. (Req DOD Delete & 26918 Springs)
