If you’re looking to enhance the performance of your Mitsubishi Lancer Evolution 8, installing an HKS Super SQV Blow-Off Valve is a great modification. This guide will walk you through the step-by-step process of installing the valve, ensuring you achieve the best performance boost possible.
Tools and Materials Needed
- HKS Super SQV Blow-Off Valve
- 3/4” Vacuum Hose
- Socket Set
- Wrenches
- Phillips and Flathead Screwdrivers
- Hose Clamps
- Drill and Drill Bits
- Safety Glasses
- Gloves
Preparation Steps
Before starting the installation, ensure you have a clean workspace and all necessary tools and materials. It’s important to work in a well-ventilated area, and wearing safety glasses and gloves is recommended for protection.
Step 1: Locate the Factory Recirculation Valve
Begin by locating the factory recirculation valve on your Evo 8. It is typically found near the throttle body. You may need to remove some engine covers or components to gain better access.
Step 2: Remove the Factory Valve
Using your socket set, carefully remove the bolts securing the factory recirculation valve. Disconnect any hoses attached to the valve, and set it aside for potential reuse or disposal.
Installing the HKS Super SQV
Step 3: Prepare the HKS Valve
Take the HKS Super SQV Blow-Off Valve out of its packaging. Familiarize yourself with its components, including the mounting bracket and fittings.
Step 4: Mount the HKS Valve
Position the HKS valve in the same location as the factory valve. Use the provided mounting bracket to secure it in place. Ensure that it is tight and won’t move during operation.
Step 5: Connect the Vacuum Hose
Cut a piece of the 3/4” vacuum hose to the required length. Attach one end to the HKS valve and the other end to a suitable vacuum source on the intake manifold. Secure both ends with hose clamps to prevent leaks.
Finalizing the Installation
Step 6: Recheck All Connections
Before starting the engine, double-check all connections and ensure that everything is secured. Make sure there are no loose bolts or hoses that could cause issues.
Step 7: Start the Engine
Start your Evo 8 and listen for any unusual sounds. The HKS Super SQV should produce a distinct sound when releasing pressure. If everything sounds normal, you’re ready to take your car for a test drive.
Testing Your New Blow-Off Valve
After installation, it’s essential to test the performance of your new blow-off valve. Pay attention to how your vehicle responds under boost and during shifts.
Step 8: Performance Check
During your test drive, make sure to monitor the boost levels and the operation of the HKS valve. It should open and release pressure smoothly, enhancing your vehicle’s performance.
Step 9: Adjustments if Necessary
If you notice any issues, such as the valve not opening or closing properly, you may need to make adjustments to the spring tension or check for any vacuum leaks.
Conclusion
Installing an HKS Super SQV Blow-Off Valve on your Evo 8 can significantly enhance performance and provide an exciting auditory experience. By following these steps, you can ensure a successful installation and enjoy the benefits of improved boost response and throttle performance.
