The Mitsubishi Eclipse has long been a favorite among car enthusiasts, especially for those looking to enhance performance without diving into forced induction. For naturally aspirated (N/A) models, optimizing the engine’s airflow and timing can yield significant power gains. This article will explore camshaft and intake upgrades that can help achieve a 20 horsepower increase.
Understanding Performance Mods for N/A Engines
When it comes to performance modifications for naturally aspirated engines, the key lies in improving the engine’s efficiency. This can be accomplished through various upgrades, primarily focusing on the camshaft and intake system. These components play crucial roles in how well the engine breathes and performs under load.
Camshaft Upgrades
The camshaft is a vital component that controls the timing and duration of the engine’s intake and exhaust valves. Upgrading the camshaft can lead to improved airflow, which translates to better performance. Here are some key points to consider:
- Choosing the Right Camshaft: Opt for a camshaft designed specifically for N/A performance. Look for options that offer a higher lift and longer duration.
- Installation: Proper installation is crucial. Consider professional help to ensure that the camshaft is timed correctly.
- Tuning: After installing a new camshaft, re-tuning the engine is essential to maximize the gains from the upgrade.
Types of Camshafts
There are several types of camshafts available for the Mitsubishi Eclipse, each offering different performance characteristics:
- Performance Camshafts: These are designed for higher RPM ranges and provide better throttle response.
- Street Camshafts: These offer a good balance between performance and drivability, making them suitable for daily use.
Intake Upgrades
Upgrading the intake system is another effective way to enhance engine performance. A more efficient intake system allows for better airflow into the engine, which can significantly improve power output. Here are some considerations:
- Cold Air Intakes: Installing a cold air intake system can help lower the intake air temperature, resulting in denser air and improved combustion.
- Intake Manifold: Upgrading to a performance intake manifold can increase airflow and optimize the engine’s power band.
- Throttle Body: Consider upgrading the throttle body for better airflow and response.
Choosing the Right Intake System
When selecting an intake system for your Mitsubishi Eclipse, keep the following in mind:
- Material: Look for intakes made from lightweight materials like aluminum or high-quality plastics that can withstand heat.
- Design: Ensure the design promotes smooth airflow and minimizes turbulence.
Combining Camshaft and Intake Upgrades
To achieve the best performance gains, it’s beneficial to combine camshaft and intake upgrades. When these components work in harmony, the engine can breathe more freely, resulting in enhanced power output. Here’s how to effectively combine these upgrades:
- Synergy: Ensure that the camshaft and intake system are compatible with each other for optimal performance.
- Comprehensive Tuning: After installation, conduct a comprehensive engine tune to adjust fuel maps and ignition timing.
Expected Power Gains
With the right combination of camshaft and intake upgrades, achieving a 20 horsepower gain is realistic. However, the actual gains can vary based on several factors:
- Engine Condition: A well-maintained engine will respond better to modifications.
- Tuning Quality: The quality of the tuning process can significantly impact performance gains.
- Supporting Mods: Other modifications, such as exhaust upgrades, can complement camshaft and intake changes.
Conclusion
Upgrading the camshaft and intake system of a Mitsubishi Eclipse N/A can lead to significant performance improvements, including a potential 20 horsepower gain. By carefully selecting the right components and ensuring proper installation and tuning, car enthusiasts can enjoy a more responsive and powerful driving experience. Whether you’re a seasoned modifier or a newcomer, these upgrades can transform your Eclipse into a more exhilarating ride.
