COMP Cams HRT Blower Stage 2 Hydraulic Roller Camshaft
2003–2008 Dodge 5.7L / 6.1L HEMI
112-337-11
Overview:
The COMP Cams HRT Blower Stage 2 Hydraulic Roller Camshaft is engineered specifically for Dodge 5.7L and 6.1L HEMI engines from 2003 to 2008, designed to maximize power and torque in turbocharged and supercharged applications. This camshaft is ideal for enthusiasts seeking substantial performance gains for larger blower setups and more race-oriented builds. Featuring advanced lobe designs and innovative technology, it delivers improved horsepower and engine stability at high RPMs while maintaining durability.
Built to handle the rigors of forced induction, the HRT Stage 2 camshaft offers a balanced combination of aggressive performance and reliable operation, making it a top choice for serious street and track applications.
Key Features:
This camshaft incorporates the latest advancements from COMP Cams to optimize power delivery and engine longevity:
- Low Shock Technology: Lobe profiles designed to maximize horsepower while reducing valve spring load and improving stability at high RPM.
- Micro Surface Enhancement (MSE): Advanced finishing process that reduces surface roughness, increasing strength and load-bearing capacity by 250%.
- Stage 2 Performance: Tailored for larger blowers and race-oriented builds, providing significant gains over stock camshafts.
- Hydraulic Roller Design: Ensures smooth operation and compatibility with factory-style hydraulic lifters.
- Dyno Tested to 7500+ RPM: Validated for high-rev performance when used with required supporting components.
- Compatibility: Designed for Dodge 5.7L and 6.1L HEMI engines without Variable Valve Timing (VVT).
- Requires Supporting Upgrades: Must be used with COMP Cams DOD Delete Kit and upgraded valve springs for optimal performance.
Construction & Design:
The HRT Blower Stage 2 camshaft is precision-engineered from high-quality materials to withstand the increased stresses of forced induction. The Micro Surface Enhancement (MSE) finishing process enhances the camshaft's durability by smoothing the lobe surfaces, which reduces friction and wear. This treatment significantly increases the effective load-bearing area, allowing the camshaft to handle higher loads without compromising reliability.
COMP Cams’ proprietary Low Shock Technology lobe profiles reduce the impact forces on valve springs, extending their life and maintaining valve train stability at elevated RPMs. The hydraulic roller design ensures compatibility with factory-style lifters while delivering aggressive performance characteristics.
Performance & Sound
Optimized for turbocharged and supercharged Dodge HEMI engines, this camshaft delivers noticeable gains in horsepower and torque across the RPM range. Its aggressive profile supports higher engine speeds and improved throttle response, making it well-suited for both street performance and competitive racing environments. The camshaft’s design also contributes to a more aggressive engine sound, enhancing the overall driving experience.
Installation & Fitment:
This camshaft fits 2003 to 2008 Dodge 5.7L and 6.1L HEMI engines without Variable Valve Timing (VVT). Installation requires the use of a COMP Cams DOD Delete Kit and upgraded valve springs (such as the 7228 springs) to handle the increased valve train loads. For 2009 and newer 5.7L to 6.4L HEMI engines with VVT, additional components like a phaser limiter or lock kit are necessary, but these do not apply to this specific camshaft.
Professional installation is recommended to ensure proper timing and valve train setup, as well as to verify compatibility with your forced induction system.
