Honda S2000 Supercharger Kits: Adding 70-100hp with Roots and Centrifugal Systems

by

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 of the most effective ways to achieve significant horsepower gains is by installing a supercharger. This article will explore the various supercharger kits available for the Honda S2000, focusing on both Roots and centrifugal systems, and how they can add 70-100 horsepower to your vehicle.

Understanding Superchargers

Superchargers are forced induction devices that compress the air entering the engine, allowing for more air and fuel to be burned. This results in increased power output. There are two primary types of superchargers used in aftermarket applications: Roots and centrifugal superchargers.

Roots Superchargers

Roots superchargers are positive displacement devices that provide immediate power boost. They work by trapping air in two rotors and forcing it into the engine. This type of supercharger is known for its low-end torque and responsiveness.

  • Immediate Power Delivery: Roots superchargers provide power almost instantaneously.
  • Low-End Torque: They excel in producing torque at lower RPMs, making them ideal for street driving.
  • Sound: The unique whine of a Roots supercharger is often appealing to enthusiasts.

Centrifugal Superchargers

Centrifugal superchargers, on the other hand, resemble turbochargers in their operation. They compress air using a rotating impeller and are more efficient at higher RPMs. This makes them suitable for those looking for peak power at higher engine speeds.

  • High RPM Power: Centrifugal superchargers produce more power at higher RPMs.
  • Efficiency: They tend to be more efficient than Roots superchargers, especially in terms of power-to-boost ratio.
  • Stealthy Operation: They often produce less noise compared to Roots systems.

Several manufacturers offer supercharger kits specifically designed for the Honda S2000. Here are some of the most popular options:

  • Greddy Supercharger Kit: This kit features a centrifugal supercharger that offers a boost of around 7-8 psi, resulting in a gain of approximately 100 horsepower.
  • Comptech Supercharger: A Roots-style supercharger that provides a significant increase in torque and power, making it a favorite among S2000 enthusiasts.
  • Jackson Racing Supercharger: Known for its reliability and performance, this Roots supercharger kit can add around 70-80 horsepower.
  • Vortech Supercharger: A centrifugal option that provides a balance of efficiency and power, suitable for both street and track use.

Installation Considerations

Installing a supercharger kit on your Honda S2000 can be a rewarding process, but it’s essential to consider a few factors before proceeding.

  • Professional Installation: While some experienced enthusiasts may tackle the installation themselves, hiring a professional is recommended for the best results.
  • Tuning: After installation, proper tuning is crucial to ensure the engine runs smoothly and efficiently with the new supercharger.
  • Supporting Mods: Consider upgrading other components such as the exhaust system, fuel system, and cooling system to handle the increased power.

Benefits of Adding a Supercharger

Adding a supercharger to your Honda S2000 comes with numerous benefits that enhance both performance and driving experience.

  • Increased Horsepower: A supercharger can significantly boost horsepower, making your S2000 even more thrilling to drive.
  • Improved Torque: Enhanced torque delivery improves acceleration and responsiveness.
  • Enhanced Driving Experience: The added power transforms the driving dynamics, making it more enjoyable on both the street and track.

Potential Drawbacks

While supercharging offers many advantages, there are potential drawbacks to consider as well.

  • Cost: Supercharger kits and installation can be expensive, requiring a significant investment.
  • Maintenance: Supercharged engines may require more frequent maintenance and monitoring.
  • Reliability Concerns: Depending on the setup, there may be concerns regarding engine reliability and longevity.

Conclusion

Supercharging your Honda S2000 with a Roots or centrifugal system can yield impressive horsepower gains of 70-100hp. Whether you seek immediate power delivery or high RPM efficiency, there are options available to suit your needs. With careful consideration of installation, tuning, and supporting modifications, you can enjoy a thrilling driving experience that elevates your S2000 to new heights.
