COMP Cams HRT Blower Stage 1 Hydraulic Roller Camshaft

2003–2008 Dodge 5.7L / 6.1L Hemi

112-335-11

Overview:

The COMP Cams HRT Blower Stage 1 Hydraulic Roller Camshaft is engineered specifically for Dodge 5.7L and 6.1L Hemi engines from 2003 to 2008. Designed to optimize power and torque for turbocharged and supercharged applications, this camshaft delivers significant performance gains while maintaining reliability. Ideal for enthusiasts running stock bottom ends with 2.5L or smaller blowers, it offers excellent throttle response and enhanced engine stability at higher RPMs.

Utilizing advanced lobe designs and Low Shock Technology, this camshaft balances aggressive power output with valve train durability, making it a perfect upgrade for street-driven forced induction builds seeking improved performance without sacrificing longevity.

Key Features:

This camshaft incorporates the latest COMP Cams innovations to maximize horsepower and torque gains for supercharged and turbocharged Dodge Hemi engines:

• Low Shock Technology lobe profiles reduce valve spring load and improve high RPM stability
• Micro Surface Enhancement (MSE) finishing process increases strength by reducing surface roughness and boosting load-bearing area by 250%
• Stage 1 profile optimized for mild street use with 2.5L or smaller superchargers
• Improved throttle response and power delivery tailored for forced induction setups
• Requires COMP Cams DOD Delete Kit and upgraded valve springs for proper operation
• Compatible with 5.7L and 6.1L Hemi engines without Variable Valve Timing (VVT)
• Durable hydraulic roller design reduces wear and maintenance compared to flat tappet cams

Construction & Design:

The HRT Blower Stage 1 camshaft is manufactured using premium materials and advanced engineering techniques to withstand the increased stresses of forced induction. The Micro Surface Enhancement (MSE) finishing process refines the cam lobes’ surface, significantly enhancing fatigue strength and wear resistance. This results in a camshaft capable of handling higher loads and RPMs without compromising durability.

The hydraulic roller design reduces friction and valve train shock, contributing to smoother operation and extended component life. COMP Cams’ precise lobe profiles ensure optimal valve timing for boosted engines, improving airflow and combustion efficiency.

Performance & Sound

This camshaft delivers noticeable gains in average power and torque throughout the RPM range, especially under boost from turbochargers or superchargers. The Low Shock Technology reduces valve spring load, allowing for more aggressive timing without sacrificing reliability. Drivers will experience sharper throttle response and a more aggressive engine note characteristic of performance camshafts, enhancing the driving experience.

Installation & Fitment:

Installation requires removal of the factory camshaft and installation of the COMP Cams DOD Delete Kit along with upgraded valve springs (COMP Cams part #26918) to handle the increased loads. This camshaft is designed for Dodge 5.7L and 6.1L Hemi engines from 2003 to 2008 without Variable Valve Timing (VVT). Engines with VVT or later model years may require additional components such as phaser limiters or lock kits.

Professional installation is recommended to ensure proper timing and valve train setup. This camshaft is ideal for stock bottom end engines equipped with 2.5L or smaller superchargers, providing a reliable and effective power upgrade.
