The Chevy Cobalt SS is known for its impressive performance, but enthusiasts often seek ways to push the limits even further. One of the most effective methods to increase horsepower is by upgrading to aftermarket camshafts. In this article, we will explore how aftermarket camshafts can help you achieve up to 330 horsepower in your Chevy Cobalt SS.
Understanding Camshafts
Camshafts play a crucial role in your engine’s performance. They control the timing and duration of the intake and exhaust valves, which directly affects airflow and engine efficiency. Upgrading to aftermarket camshafts can significantly enhance these parameters, leading to improved power output.
Benefits of Aftermarket Camshafts
When considering aftermarket camshafts for your Chevy Cobalt SS, it’s essential to understand the benefits they provide:
- Increased Horsepower: Aftermarket camshafts can boost horsepower significantly, often reaching up to 330 hp with proper tuning and supporting mods.
- Enhanced Torque: Improved torque delivery enhances acceleration and overall driving experience.
- Better Engine Efficiency: Optimized valve timing can lead to more efficient combustion, improving fuel economy.
- Customization Options: Various camshaft profiles allow for tailored performance based on driving style and preferences.
Choosing the Right Aftermarket Camshaft
Not all aftermarket camshafts are created equal. Here are key factors to consider when selecting the right camshaft for your Cobalt SS:
- Lift and Duration: Higher lift and longer duration can improve airflow but may require additional modifications.
- Profile Type: Choose between performance-oriented profiles for racing or milder profiles for daily driving.
- Compatibility: Ensure the camshaft is compatible with your engine setup and other modifications.
- Brand Reputation: Opt for reputable brands known for quality and performance.
Installation Process
Installing aftermarket camshafts can be a complex process. Here’s a general overview of the steps involved:
- Gather Tools and Parts: Ensure you have all necessary tools, gaskets, and components before starting.
- Remove Engine Components: Take off the intake manifold, valve covers, and timing chain or belt.
- Replace Camshaft: Carefully remove the stock camshaft and install the new aftermarket camshaft, ensuring proper alignment.
- Reassemble Engine: Reinstall all components in reverse order, ensuring that all gaskets and seals are replaced.
- Re-tune Engine: After installation, it’s crucial to re-tune the engine for optimal performance with the new camshaft.
Supporting Modifications
To reach the maximum horsepower potential with aftermarket camshafts, consider additional modifications:
- Upgraded Intake and Exhaust: A high-performance intake and exhaust system can improve airflow and complement your camshaft upgrade.
- ECU Tuning: Proper tuning is essential to maximize performance gains and ensure engine reliability.
- Performance Headers: Upgrading to performance headers can enhance exhaust flow, further increasing horsepower.
- Improved Fuel System: Upgrading fuel injectors and fuel pumps may be necessary to support increased power demands.
Potential Challenges
While aftermarket camshafts can provide significant power gains, there are challenges to be aware of:
- Engine Wear: Aggressive cam profiles can lead to increased wear on engine components.
- Driveability Issues: Some camshafts may negatively impact idle quality and low-end torque.
- Increased Noise: Aftermarket camshafts can result in a louder engine, which may not be suitable for all drivers.
- Cost: Quality camshafts and installation can be expensive, so budget accordingly.
Conclusion
Upgrading to aftermarket camshafts on your Chevy Cobalt SS can unlock impressive power gains, potentially reaching up to 330 horsepower. With careful selection, proper installation, and supporting modifications, you can transform your Cobalt SS into a high-performance machine. Always consider the trade-offs and ensure that your upgrades align with your driving goals.
