The Mitsubishi Lancer Evolution IX, commonly referred to as the Evo 9, is a beloved model among car enthusiasts and tuners. Known for its performance and handling, many owners look to enhance their vehicles further. One of the most significant modifications you can make is upgrading to forged pistons and connecting rods. This article will explore the power gains you can expect from such upgrades.
Understanding Forged Pistons and Connecting Rods
Forged pistons and connecting rods are aftermarket components designed for high-performance engines. Unlike their cast counterparts, forged parts are made from a single piece of metal, which gives them superior strength and durability. This is particularly important in high-stress environments like racing or high-performance street driving.
Benefits of Upgrading to Forged Components
Upgrading to forged pistons and connecting rods offers several benefits that can significantly impact your Evo 9’s performance.
- Increased Strength: Forged components can withstand higher levels of stress and pressure, making them ideal for turbocharged applications.
- Weight Reduction: Many forged parts are lighter than stock components, which can improve overall engine efficiency and responsiveness.
- Higher Compression Ratios: Forged pistons can be designed for higher compression, leading to more power and better throttle response.
- Improved Reliability: With better materials and construction, forged components can lead to a more reliable engine under extreme conditions.
Expected Power Gains
The power gains from upgrading to forged pistons and connecting rods can vary based on several factors, including the specific components used, the tuning of the engine, and other modifications. However, here are some general expectations:
- Stock vs. Forged: Many Evo 9 owners report gains of 50-100 horsepower when upgrading to forged components, especially when combined with other performance modifications.
- Turbo Upgrades: If you’re also upgrading your turbocharger, the combination of forged parts and a larger turbo can yield even greater gains, sometimes exceeding 150 horsepower.
- Engine Tuning: Proper tuning is crucial. A well-tuned engine can maximize the potential of forged components, leading to better power delivery and efficiency.
Considerations Before Upgrading
Before making the switch to forged pistons and connecting rods, there are several considerations to keep in mind:
- Cost: Forged components can be significantly more expensive than stock parts. Factor in the cost of labor and additional modifications as well.
- Installation: Professional installation is recommended to ensure everything is set up correctly. Improper installation can lead to engine failure.
- Supporting Mods: Consider whether you need other upgrades, such as a better fuel system, cooling system, or turbocharger, to support increased power levels.
- Daily Driving vs. Racing: Determine if the upgrades align with your goals. Forged components are often more beneficial for racing applications than daily driving.
Conclusion
Upgrading to forged pistons and connecting rods on your Evo 9 can lead to significant power gains and improved reliability. While the investment may be substantial, the performance benefits can make it worthwhile for enthusiasts looking to push their vehicles to the next level. Always ensure you have the right supporting modifications and professional installation to maximize your upgrades.
