Upgrading your Mitsubishi Evo IX intercooler is a crucial step in maximizing the performance of your MS3 big turbo. The stock intercooler can become a bottleneck in your engine’s performance, especially when you’re pushing for more power. This article will guide you through the benefits of upgrading your intercooler and the steps involved in making this important modification.
Why Upgrade Your Intercooler?
The intercooler plays a vital role in the turbocharging system by cooling the air that enters the engine. Cooler air is denser, which means more oxygen can be packed into the combustion chamber, leading to better combustion and more power. Here are some reasons why upgrading your intercooler is beneficial:
- Improved Airflow: A larger intercooler allows for better airflow, reducing pressure drop and increasing efficiency.
- Lower Intake Temperatures: Enhanced cooling reduces the temperature of the air entering the engine, which helps prevent knock and allows for more aggressive tuning.
- Increased Power Output: With more efficient cooling and airflow, you can achieve higher horsepower and torque figures.
- Better Reliability: A high-performance intercooler can withstand higher boost levels, providing greater reliability under demanding conditions.
Choosing the Right Intercooler
When selecting an intercooler for your Evo IX, consider the following factors:
- Core Size: A larger core size typically means better cooling capabilities. However, ensure it fits within your vehicle’s front end without obstructing airflow to other components.
- Material: Look for an intercooler made from high-quality materials, such as aluminum, which offers durability and efficient heat transfer.
- End Tank Design: The design of the end tanks can affect airflow. Choose designs that minimize turbulence and maximize flow.
- Brand Reputation: Consider reputable brands known for performance parts, as they often provide better quality and support.
Installation Process
Installing a new intercooler can be a straightforward process if you follow the right steps. Here’s a general guide to help you with the installation:
Tools and Materials Needed
- Socket set
- Wrenches
- Intercooler kit
- Hoses and clamps
- Coolant (if necessary)
- Torque wrench
Step-by-Step Installation
Follow these steps to install your new intercooler:
- 1. Prepare Your Workspace: Ensure your vehicle is on a flat surface and secure it with jack stands.
- 2. Remove the Stock Intercooler: Disconnect the hoses and clamps, and unbolt the stock intercooler from its mounting points.
- 3. Install the New Intercooler: Position the new intercooler in place and secure it using the provided hardware.
- 4. Connect Hoses: Attach the hoses and clamps to the new intercooler, ensuring a tight fit to prevent leaks.
- 5. Check for Interference: Make sure that the intercooler does not obstruct any other components in the engine bay.
- 6. Reassemble Everything: Reinstall any parts that were removed during the process and ensure all connections are secure.
- 7. Test the System: Start the engine and check for any leaks or issues. Monitor the intake temperatures during a test drive to ensure proper function.
Performance Tuning After Installation
After upgrading to a new intercooler, it’s essential to tune your vehicle to take full advantage of the increased airflow and cooler temperatures. Here are some tuning considerations:
- ECU Remapping: A custom tune can adjust fuel maps and ignition timing to optimize performance with the new intercooler.
- Boost Levels: You may be able to increase boost levels safely, thanks to the improved cooling efficiency.
- Monitoring Parameters: Keep an eye on air-fuel ratios, boost pressure, and intake temperatures to ensure everything is operating within safe limits.
Conclusion
Upgrading to a Mitsubishi Evo IX intercooler when using an MS3 big turbo is a smart move for any performance enthusiast. The benefits of improved airflow, lower intake temperatures, and increased power output make this modification worthwhile. By carefully selecting the right intercooler and following the installation steps, you can enhance your vehicle’s performance significantly. Don’t forget to tune your engine to get the most out of your new setup!
