Fits Most Dodge/Jeep 6.1L/5.7L (05-10)

112-330-11

Overview:

The COMP Cams HRT Turbo Stage 1 Hydraulic Roller Camshaft is engineered specifically for Dodge 5.7L and 6.1L HEMI engines from 2003 to 2008. Designed to optimize performance in turbocharged and supercharged applications, this camshaft delivers significant gains in horsepower and torque while maintaining excellent drivability. Ideal for enthusiasts running mild street turbo setups on a stock bottom end, it offers improved throttle response and power delivery without sacrificing reliability.

This camshaft is part of COMP Cams’ advanced HRT series, which incorporates the latest lobe designs and finishing technologies to maximize engine output and durability under boost. It is a perfect upgrade for those seeking a responsive, street-friendly camshaft that supports forced induction power enhancements.

Key Features:

The HRT Turbo Stage 1 camshaft incorporates several cutting-edge technologies to enhance performance and longevity:

• Low Shock Technology: Specially designed lobe profiles that maximize horsepower and improve valve train 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 Supercharged Engines: Cam profiles tailored to boost power and torque in forced induction setups.
• Valve Spring Compatibility: Requires upgraded valve springs (COMP Cams 26918) for optimal performance and durability.
• DOD Delete Kit Required: Compatible with COMP Cams DOD Delete Kit to ensure proper operation without the stock Displacement on Demand system.
• Designed for Stock Bottom End: Ideal for 5.7L engines with factory internals running responsive street turbo systems.
• Enhanced Durability: Lobe profiles reduce valve spring load loss and improve overall valve train longevity.

Construction & Design:

Manufactured with precision CNC grinding and finished using the Micro Surface Enhancement (MSE) process, this camshaft features a hardened surface that significantly improves wear resistance and strength. The hydraulic roller design reduces friction and wear compared to flat tappet cams, contributing to smoother operation and longer service life. COMP Cams’ engineering ensures that the camshaft profiles deliver aggressive performance gains while maintaining valve train stability and reliability under boost conditions.

Performance & Sound

The HRT Turbo Stage 1 camshaft enhances throttle response and power delivery, especially in turbocharged applications. Drivers will notice improved mid-range torque and horsepower, resulting in quicker spool times and stronger acceleration. The hydraulic roller design also contributes to a smoother, quieter valvetrain compared to more aggressive race cams, making it suitable for street-driven vehicles.

Installation & Fitment:

This camshaft is designed for direct fitment in 2003–2008 Dodge 5.7L and 6.1L HEMI engines without variable valve timing (VVT). Installation requires removal of the factory camshaft and upgrading to COMP Cams valve springs (part #26918) to handle the increased lift and duration. Additionally, the COMP Cams DOD Delete Kit is mandatory to disable the factory Displacement on Demand system for proper camshaft function. For newer 5.7L to 6.4L HEMI engines with VVT (2009+), additional components such as a phaser limiter or lock kit may be required, but this camshaft is specifically for pre-VVT models.

What's Included:

• COMP Cams HRT Turbo Stage 1 Hydraulic Roller Camshaft (Part #112-330-11)
• Installation instructions (where applicable)
• Note: Valve springs and DOD Delete Kit sold separately

Ideal For:

This camshaft is ideal for Dodge 5.7L and 6.1L HEMI owners looking to upgrade their turbocharged or supercharged engines on a stock bottom end. It suits enthusiasts who want a reliable, street-friendly camshaft that delivers noticeable power gains and improved throttle response without sacrificing daily drivability. Perfect for mild to moderate forced induction builds focused on street performance and responsiveness.
