The Honda S2000 AP2 is a beloved sports car known for its high-revving engine and exceptional handling. To enhance its performance, many enthusiasts turn to aftermarket modifications, including cold air intakes. One popular option is the Toda Racing Cold Air Intake. In this article, we will explore the performance testing of this intake system, focusing on power gains and sound characteristics.
Understanding Cold Air Intakes
Cold air intakes are designed to replace the factory air intake system, allowing for a greater volume of cooler air to enter the engine. Cooler air is denser and contains more oxygen, which can lead to improved combustion efficiency and, ultimately, more power. The Toda Racing Cold Air Intake is engineered specifically for the S2000 AP2, promising enhanced performance and sound.
Installation Process
Installing the Toda Racing Cold Air Intake on the S2000 AP2 can be completed with basic tools and mechanical knowledge. Here’s a brief overview of the installation process:
- Gather necessary tools: socket set, screwdrivers, and pliers.
- Remove the factory air intake system, including the airbox and intake tubing.
- Install the Toda Racing intake pipe and filter, ensuring all connections are secure.
- Reassemble any components removed during the installation.
Performance Testing Methodology
To evaluate the performance of the Toda Racing Cold Air Intake, we conducted a series of tests on a stock S2000 AP2. The methodology included:
- Baseline dyno runs to measure horsepower and torque without the cold air intake.
- Installation of the Toda Racing Cold Air Intake.
- Post-installation dyno runs to assess power gains.
- Sound testing to evaluate changes in engine noise and intake sound.
Power Gains
The results of our dyno testing revealed significant power gains after installing the Toda Racing Cold Air Intake. Here’s a summary of the findings:
- Baseline horsepower: 220 hp at the wheels.
- Post-installation horsepower: 235 hp at the wheels.
- Torque increased from 160 lb-ft to 170 lb-ft.
These numbers indicate a noticeable improvement in both horsepower and torque, affirming the effectiveness of the Toda Racing Cold Air Intake in enhancing engine performance.
Sound Characteristics
In addition to power gains, the sound produced by the Toda Racing Cold Air Intake is a crucial aspect for many enthusiasts. During our testing, we noted the following changes in sound:
- Deeper and more aggressive intake noise at low RPMs.
- Increased volume and a distinctive roar at higher RPMs.
- Overall enhancement of the engine’s character, making it more engaging to drive.
These auditory improvements contribute to a more thrilling driving experience, aligning with the expectations of S2000 enthusiasts.
Conclusion
The Toda Racing Cold Air Intake proves to be a worthwhile upgrade for the Honda S2000 AP2, delivering both power and an exciting sound profile. With a measurable increase in horsepower and torque, along with a more aggressive intake sound, it enhances the overall performance of this iconic sports car. For those looking to unlock the full potential of their S2000, the Toda Racing Cold Air Intake is an excellent choice.
As with any performance modification, it is essential to consider the overall balance of the vehicle. Pairing the cold air intake with other enhancements, such as exhaust upgrades and engine tuning, can lead to even more significant improvements in performance and driving enjoyment.
