The Mini Cooper S is a beloved compact car known for its sporty handling and unique style. However, for those looking to boost performance, a supercharger upgrade can provide the extra horsepower needed to take driving to the next level. This article will guide you through the process of installing a Roots supercharger, which can add up to 80 additional horsepower to your Mini Cooper S.
Understanding the Roots Supercharger
The Roots supercharger is a positive displacement blower that increases the intake air volume, resulting in more power. Unlike turbochargers, which rely on exhaust gases, superchargers are driven directly by the engine’s crankshaft, providing immediate throttle response. This makes them an ideal choice for enhancing the performance of the Mini Cooper S.
Benefits of Upgrading to a Roots Supercharger
- Increased Power: Up to 80 additional horsepower.
- Improved Throttle Response: Instant power delivery.
- Enhanced Driving Experience: More engaging and fun to drive.
- Better Acceleration: Quicker off-the-line performance.
Preparing for Installation
Before beginning the installation process, it’s essential to gather all necessary tools and parts. Here’s a list of what you’ll need:
- Roots supercharger kit
- Socket set
- Torque wrench
- Screwdrivers
- Air intake modifications
- Fuel management system upgrade (if necessary)
- Basic hand tools
Step-by-Step Installation Guide
1. Preparing the Vehicle
Start by parking the Mini Cooper S on a flat surface and disconnecting the battery. This is crucial to ensure safety throughout the installation process. Remove any components that obstruct access to the engine bay, such as the air intake system and engine cover.
2. Removing the Stock Supercharger
Next, carefully remove the stock supercharger. This involves disconnecting the intake and outlet hoses, as well as the electrical connections. Use the socket set to remove the mounting bolts, ensuring to keep them organized for later use.
3. Installing the Roots Supercharger
Once the stock supercharger is removed, it’s time to install the Roots supercharger. Position it in place and align it with the mounting holes. Secure it using the bolts from the previous step, ensuring to torque them to the manufacturer’s specifications.
4. Connecting the Intake and Outlet Hoses
Reconnect the intake and outlet hoses to the Roots supercharger. Ensure that all connections are tight and free of leaks. If your supercharger kit includes a new air intake system, install it according to the provided instructions.
5. Updating the Fuel Management System
To accommodate the increased airflow and power, you may need to upgrade the fuel management system. This could involve reprogramming the ECU or installing a fuel management chip. Follow the manufacturer’s instructions carefully to ensure proper performance.
6. Final Checks and Reassembly
Before reassembling the engine bay, double-check all connections and fittings. Ensure that there are no loose wires or hoses. Reconnect the battery and start the engine to check for any leaks or unusual sounds. If everything looks good, proceed to reassemble any removed components.
Post-Installation Tips
After successfully installing the Roots supercharger, consider the following tips to maximize performance:
- Regularly check for leaks or loose connections.
- Keep up with routine maintenance, including oil changes.
- Consider upgrading other performance components, such as exhaust and suspension.
- Join Mini Cooper forums for tips and community support.
Conclusion
Upgrading to a Roots supercharger can significantly enhance the performance of your Mini Cooper S, delivering an exhilarating driving experience. By following the steps outlined in this guide, you can successfully install the supercharger and enjoy the benefits of increased horsepower and improved throttle response. Always prioritize safety and consult professionals if you encounter any challenges during the installation process.
