The Mitsubishi Lancer Evolution, commonly known as the Evo, is a legendary car in the automotive world. Renowned for its performance and tuning potential, many enthusiasts seek to enhance its power output. One of the most effective modifications to achieve this is upgrading the intercooler. This article will explore how intercooler upgrades can safely increase power from 300 to 400+ horsepower.
Understanding Intercoolers
An intercooler is a crucial component in turbocharged engines, as it cools the air compressed by the turbocharger before it enters the engine. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which leads to better combustion and increased power. Upgrading the intercooler can significantly enhance performance, especially when pushing for higher horsepower levels.
Benefits of Upgrading Your Intercooler
Upgrading the intercooler on your Evo has several benefits that contribute to improved performance and reliability:
- Improved Cooling Efficiency: A larger or more efficient intercooler can reduce intake air temperatures significantly.
- Increased Power Output: Cooler air allows for more aggressive tuning and higher boost levels, resulting in increased horsepower.
- Enhanced Engine Reliability: Lower temperatures can reduce the risk of knock and engine damage, ensuring a safer power increase.
- Better Throttle Response: Improved airflow can lead to a more responsive throttle, enhancing the overall driving experience.
Choosing the Right Intercooler
When selecting an intercooler for your Evo, consider the following factors:
- Size: A larger core can provide better cooling, but ensure it fits within your vehicle’s front end without obstructing airflow to other components.
- Type: Bar-and-plate and tube-and-fin are the two main designs. Bar-and-plate intercoolers are generally more efficient, while tube-and-fin are lighter and less expensive.
- Material: Look for intercoolers made from high-quality aluminum for durability and better heat dissipation.
- Brand Reputation: Choose a reputable brand known for quality and performance to ensure reliability and effectiveness.
Installation Process
Installing an intercooler can vary in complexity depending on the model and brand. Here’s a general overview of the installation process:
- Preparation: Gather necessary tools and parts, including the new intercooler, piping, couplers, and clamps.
- Remove the Stock Intercooler: Disconnect the battery, remove the front bumper, and carefully detach the stock intercooler and piping.
- Install the New Intercooler: Position the new intercooler in place, ensuring it is secure and properly aligned.
- Reconnect Piping: Attach the piping to the new intercooler using appropriate couplers and clamps, ensuring a tight seal.
- Reassemble the Front End: Reattach the front bumper and reconnect the battery.
Tuning After Installation
After upgrading the intercooler, tuning the engine is essential to maximize the benefits of the new component. Proper tuning can optimize air-fuel ratios and ignition timing, allowing the engine to safely handle the increased power. Consider the following:
- ECU Reflash: A reflash or remap of the engine’s ECU is often necessary to adjust for the increased airflow and boost levels.
- Dyno Testing: Use a dynamometer to measure horsepower and torque before and after tuning to ensure the desired power levels are achieved safely.
- Monitoring: After tuning, monitor engine parameters such as air-fuel ratio and boost pressure to ensure the engine operates within safe limits.
Conclusion
Upgrading the intercooler on your Mitsubishi Lancer Evolution is a powerful way to safely increase horsepower from 300 to 400+. With improved cooling efficiency, increased power output, and enhanced engine reliability, a quality intercooler upgrade can transform your driving experience. Remember to choose the right intercooler, follow proper installation procedures, and tune your engine for the best results. Enjoy the thrill of driving a more powerful and responsive Evo!
