  • Optimized Torque Curve: The cam profile is designed to improve the torque curve, making power delivery more effective across the RPM range.
  • Enhanced Sound: A performance camshaft gives your engine a more aggressive sound, adding to the overall driving enjoyment.

Installation Process

Installing a Mopar Stage 2 Cam requires some mechanical knowledge and the right tools. Here’s a step-by-step guide to help you through the process:

  • Gather Tools and Materials: You will need a socket set, torque wrench, camshaft installation tool, and the Mopar Stage 2 Cam kit.
  • Disconnect the Battery: Always start by disconnecting the negative battery cable to prevent any electrical issues.
  • Remove Engine Covers: Take off any plastic engine covers to access the valve covers and camshaft.
  • Remove Valve Covers: Carefully unbolt and remove the valve covers to expose the rocker arms and camshaft.
  • Remove Rocker Arms: Take off the rocker arms and pushrods, labeling them for reinstallation.
  • Remove the Old Cam: Unbolt the timing chain cover, remove the timing chain, and then pull out the old camshaft.
  • Install the New Cam: Carefully install the Mopar Stage 2 Cam, ensuring proper alignment with the timing chain.
  • Reassemble the Engine: Reinstall the rocker arms, pushrods, and valve covers. Ensure all bolts are torqued to specifications.
  • Reconnect the Battery: Once everything is back in place, reconnect the battery and check for any leaks.

Tuning Your Engine

After installing the Mopar Stage 2 Cam, it is crucial to tune your engine for optimal performance. A proper tune will adjust fuel maps and ignition timing to take full advantage of the new camshaft. Here’s what you need to consider:

  • ECU Reflash: Use a performance tuner to reflash the ECU, ensuring that it recognizes the new cam specifications.
  • Dyno Tuning: Consider having your vehicle dyno-tuned to get precise adjustments for maximum performance.
  • Monitor Performance: After tuning, monitor your vehicle’s performance and make adjustments as necessary.

Impact on Daily Driving

Upgrading to a Mopar Stage 2 Cam will undoubtedly change the driving dynamics of your 5.7 HEMI. While the increase in horsepower and throttle response is significant, there are other factors to consider:

  • Idle Characteristics: The new cam may cause a rougher idle, which is typical for performance camshafts.
  • Fuel Economy: While power increases, fuel economy may decrease slightly due to the aggressive nature of the cam.
  • Daily Usability: Many drivers find the enhanced performance worth the trade-offs, especially in performance-oriented driving scenarios.

Conclusion

Upgrading to a Mopar Stage 2 Cam is an excellent way to maximize the potential of your 5.7 HEMI engine. With increases in horsepower, improved throttle response, and an overall more engaging driving experience, this upgrade is highly recommended for enthusiasts looking to elevate their vehicle’s performance. Just be sure to follow the installation steps carefully and consider tuning for the best results.
