COMP Cams Turbo HRT Stage 2 Master Camshaft Kit
2003–2008 Dodge 5.7 HEMI
MK112-332-11
Overview:
The COMP Cams Turbo HRT Stage 2 Master Camshaft Kit is engineered specifically for the Dodge 5.7L HEMI engines from 2003 to 2008, delivering significant power and torque gains for turbocharged and supercharged applications. Designed with advanced lobe profiles and Low Shock Technology, this camshaft kit maximizes horsepower while maintaining valve train stability at high RPMs. Ideal for enthusiasts seeking to optimize performance with larger turbochargers, the Stage 2 kit supports builds ranging from aggressive street setups to race-oriented engines.
This kit requires complementary upgrades such as a DOD (Displacement on Demand) delete kit and upgraded valve springs to ensure reliable operation and durability under boosted conditions. It is dyno tested to perform reliably beyond 7,500 RPM, making it a robust choice for high-performance turbocharged Dodge HEMI builds.
Key Features:
The Turbo HRT Stage 2 camshaft incorporates cutting-edge technology and design elements to enhance engine output and longevity:
- Low Shock Technology: Specially designed lobe profiles reduce valve spring load and improve stability at high RPM.
- Micro Surface Enhancement (MSE): Advanced finishing process that reduces surface roughness, increasing strength and load-bearing capacity by 250%.
- Optimized for Turbo and Supercharger Use: Cam profiles tailored for low backpressure on the hot side, ideal for larger turbochargers.
- Stage 2 Performance: Balanced for substantial power gains while maintaining streetability and reliability.
- Durability: Profiles designed to be easier on valve springs, extending component life under boosted conditions.
- High RPM Capability: Dyno tested to exceed 7,500 RPM for aggressive performance applications.
- Requires Supporting Mods: Compatible with COMP Cams DOD delete kit and 7228 valve springs for optimal function.
- Phaser Lock Required: For 5.7L-6.4L VVT engines from 2009+, a phaser limiter or lock kit is necessary (not included).
Construction & Design:
COMP Cams employs precision engineering and premium materials in the Turbo HRT Stage 2 camshaft. The cam lobes undergo the Micro Surface Enhancement (MSE) finishing process, which significantly improves surface smoothness and fatigue resistance. This treatment enhances the camshaft’s ability to withstand higher loads and stresses typical of forced induction setups. The Low Shock Technology lobe profiles reduce the mechanical shock transmitted to valve springs, promoting longer spring life and improved valve train stability. The camshaft is designed to fit directly into the factory location with necessary supporting components, ensuring a seamless upgrade path.
Performance & Sound
The Stage 2 camshaft kit delivers a noticeable increase in mid to high RPM power and torque, optimized for turbocharged Dodge 5.7L HEMI engines. The cam profile enhances throttle response and overall engine efficiency under boost, supporting larger turbochargers with reduced backpressure. While primarily focused on performance gains, the camshaft also contributes to a more aggressive engine sound characteristic of high-performance forced induction builds.
Installation & Fitment:
This kit is designed for 2003–2008 Dodge 5.7L HEMI engines and requires the removal of the factory camshaft and installation of the Stage 2 camshaft along with upgraded valve springs (COMP Cams 7228 springs) and a DOD delete kit to disable the displacement on demand system. For engines equipped with variable valve timing (VVT) from 2009 onward, additional components such as a phaser limiter or lock kit are necessary but not included in this kit. Professional installation is recommended to ensure proper timing and valve train setup, as well as to verify compatibility with other engine modifications.
What's Included:
- COMP Cams Turbo HRT Stage 2 Master Camshaft
- Installation instructions (where applicable)
- Note: DOD delete kit, upgraded valve springs, and phaser lock kit sold separately
Ideal For:
This camshaft kit is perfect for Dodge 5.7L HEMI owners looking to maximize power output on turbocharged or supercharged setups. It suits enthusiasts building aggressive street machines, weekend racers, or track-focused vehicles requiring reliable high-RPM performance. The Stage 2 profile balances power gains with valve train durability, making it a versatile choice for forced induction builds demanding both strength and efficiency.
