The Honda S2000 is a beloved sports car known for its high-revving engine and exceptional handling. For many enthusiasts, enhancing performance is a top priority. Among the various options available, supercharging is a popular choice. This article compares two prominent types of superchargers: the Lysholm twin-screw and the Roots supercharger, focusing on their performance gains for the S2000.
Understanding Supercharger Types
Before diving into the specifics of the Lysholm and Roots superchargers, it’s essential to understand how each type operates and their general characteristics.
- Lysholm Twin-Screw Supercharger: This supercharger uses two interlocking screws to compress air, providing a constant flow of boost. It is known for its efficiency and ability to produce power across a wide RPM range.
- Roots Supercharger: The Roots design features two rotors that draw in air and compress it before sending it to the engine. It delivers a significant amount of boost but is typically more power-hungry than the twin-screw design.
Performance Gains Overview
When considering performance gains, both supercharger types have their advantages and disadvantages. The choice between them often depends on the desired driving style and specific performance goals.
Lysholm Twin-Screw Advantages
- Efficiency: The twin-screw design is generally more efficient, providing better power gains per unit of boost.
- Power Band: It offers a broader power band, making it suitable for both street and track applications.
- Heat Management: Twin-screw superchargers typically produce less heat, allowing for more consistent performance.
Roots Supercharger Advantages
- Immediate Response: Roots superchargers provide instant throttle response, which can enhance driving excitement.
- High Boost Levels: They can generate high boost levels at low RPMs, making them suitable for applications requiring significant low-end torque.
- Simple Design: The simpler design can lead to easier installation and maintenance in some cases.
Comparative Performance Metrics
To better understand the performance gains of each supercharger type, let’s compare some critical metrics based on user experiences and dyno tests.
- Power Output: Lysholm superchargers often yield higher peak power figures, typically ranging from 350 to 400 horsepower, depending on the setup.
- Torque Delivery: Roots superchargers can provide substantial torque increases at lower RPMs, which can be beneficial for street performance.
- Boost Pressure: Both superchargers can achieve similar boost levels; however, the efficiency of the twin-screw often allows for higher effective power output.
Installation Considerations
When deciding between a Lysholm twin-screw and a Roots supercharger for the S2000, installation considerations are crucial. Each type has unique requirements that can impact the overall project.
- Lysholm Installation: Typically requires more complex plumbing and tuning but offers a cleaner integration with the engine.
- Roots Installation: Generally simpler, but may require modifications to the engine bay due to its larger size.
Cost Analysis
Cost is a significant factor in any performance upgrade. Both supercharger types come with different price points, which can vary based on brand and features.
- Lysholm Superchargers: Typically priced higher due to their advanced technology and efficiency, often ranging from $5,000 to $8,000 including installation.
- Roots Superchargers: Generally more affordable, with prices ranging from $3,500 to $6,500, making them attractive for budget-conscious enthusiasts.
Conclusion
Choosing between a Lysholm twin-screw and a Roots supercharger for the Honda S2000 depends on individual performance goals, budget, and installation preferences. The Lysholm offers superior efficiency and power delivery, while the Roots provides immediate throttle response and affordability. Ultimately, both options can significantly enhance the driving experience, making the S2000 an even more thrilling sports car.
