The Honda S2000 is a beloved sports car known for its high-revving engine and exceptional handling. However, many enthusiasts seek to enhance its performance further. One popular method is to install a Roots supercharger, which can help achieve an impressive 350 horsepower. In this article, we will explore the installation and tuning tips for successfully adding a Roots supercharger to your Honda S2000.
Understanding the Roots Supercharger
A Roots supercharger is a type of positive displacement supercharger that compresses air and forces it into the engine’s intake. This results in increased power output, especially at lower RPMs. The Roots design is known for its simplicity and effectiveness, making it an excellent choice for boosting the performance of the Honda S2000.
Preparing for Installation
Before diving into the installation process, it’s essential to gather all necessary tools and components. Here’s a checklist to ensure you’re fully prepared:
- Roots supercharger kit specific to Honda S2000
- Basic hand tools (wrenches, sockets, screwdrivers)
- Torque wrench
- Vacuum gauge
- Fuel pressure gauge
- ECU tuning software or access to a tuner
Installation Steps
Installing a Roots supercharger on your Honda S2000 requires careful attention to detail. Follow these steps for a successful installation:
- Remove the Stock Intake System: Begin by disconnecting the battery and removing the stock intake system, including the air filter and intake manifold.
- Install the Supercharger Bracket: Attach the supercharger bracket to the engine block using the provided hardware. Ensure it is securely fastened.
- Mount the Supercharger: Carefully mount the Roots supercharger onto the bracket. Make sure to use the correct gaskets to prevent any air leaks.
- Connect the Intake Piping: Install the intake piping that connects the supercharger to the throttle body. Ensure all clamps are tight.
- Install the Fuel System Upgrades: Upgrade the fuel injectors and fuel pump as necessary to support the increased power output.
- Reconnect the Battery: Once all components are installed, reconnect the battery.
Tuning the Engine
After the installation, proper tuning is crucial to ensure the engine runs smoothly and efficiently. Here are some tuning tips to help you achieve optimal performance:
- Use a Quality Tuner: Work with a professional tuner who has experience with supercharged Honda S2000s. This ensures that the engine is tuned correctly for the new setup.
- Monitor Air-Fuel Ratios: Use a wideband O2 sensor to monitor air-fuel ratios during tuning. Aim for a safe and efficient mixture to prevent engine damage.
- Adjust Timing Maps: Modify the ignition timing maps to accommodate the added boost from the supercharger. This will help improve power delivery and throttle response.
- Test Drive: After tuning, take the car for a test drive. Monitor performance and make any necessary adjustments based on real-world feedback.
Common Issues and Troubleshooting
While installing a Roots supercharger can significantly boost your Honda S2000’s performance, you may encounter some common issues. Here are a few troubleshooting tips:
- Boost Leaks: Check for any boost leaks in the intake system. A vacuum gauge can help identify leaks that may affect performance.
- Fuel Delivery Problems: Ensure that the upgraded fuel pump and injectors are functioning correctly. Insufficient fuel delivery can lead to lean conditions and engine damage.
- Overheating: Monitor engine temperatures closely. If overheating occurs, consider upgrading the cooling system to handle the increased power.
- Check Engine Light: If the check engine light comes on, use an OBD-II scanner to diagnose the issue. Address any error codes promptly.
Conclusion
Achieving 350 horsepower with a Roots supercharger on your Honda S2000 is an exciting project that can significantly enhance your driving experience. By following the installation steps, tuning tips, and troubleshooting advice outlined in this article, you can enjoy the thrill of a supercharged S2000. Always remember to prioritize safety and consult professionals when necessary to ensure a successful upgrade.
