The B-series engine has long been a favorite among automotive enthusiasts, particularly those who enjoy tuning and modifying their vehicles for performance. In this article, we’ll explore the results of a real-world dyno test that showcases the impressive power gains achieved through a Stage 2 cam upgrade. With a relatively modest investment of $1,200, we will see how this upgrade can push the limits of the B-series engine to reach 200 horsepower.
Understanding the B-Series Engine
The B-series engine family, produced by Honda, is known for its robust design and potential for high performance. Commonly found in models like the Civic and Integra, these engines have a strong aftermarket support, making them popular choices for modifications. The B-series engines feature a DOHC design, allowing for higher RPMs and improved airflow, which are critical for performance upgrades.
The Stage 2 Cam Upgrade
A Stage 2 cam upgrade is designed to enhance the engine’s performance characteristics significantly. This upgrade typically involves replacing the stock camshaft with one that has a more aggressive profile, allowing for increased lift and duration. The result is improved airflow into the engine, which can lead to higher horsepower and torque figures.
Benefits of a Stage 2 Cam
- Increased horsepower and torque
- Improved throttle response
- Enhanced engine sound
- Better performance at higher RPMs
Dyno Testing Procedure
To evaluate the effectiveness of the Stage 2 cam upgrade, a series of dyno tests were conducted. The testing involved a baseline run with the stock camshaft, followed by a run after the installation of the Stage 2 cam. The dyno used was a reputable brand known for accuracy, ensuring reliable results.
Baseline Results
The baseline run with the stock camshaft produced a respectable output of approximately 160 horsepower at the wheels. This figure is typical for a well-maintained B-series engine, demonstrating the solid performance capabilities of the stock configuration.
Post-Upgrade Results
After the installation of the Stage 2 cam, the same engine was tested again on the dyno. The results were impressive, with the engine producing a peak output of 200 horsepower at the wheels. This represented a significant gain of 40 horsepower, showcasing the effectiveness of the cam upgrade.
Factors Influencing Dyno Results
While the dyno results are promising, several factors can influence the final horsepower figures. These include:
- Engine condition and maintenance
- Fuel quality and type
- Air intake and exhaust modifications
- Environmental conditions during testing
Real-World Applications
The increase to 200 horsepower from a simple $1,200 upgrade opens up numerous possibilities for B-series enthusiasts. Whether used for daily driving, track days, or competitive racing, this level of power can significantly enhance the driving experience.
Considerations for Daily Drivers
For those considering this upgrade for a daily driver, it’s essential to weigh the benefits against potential drawbacks. While the added power is enticing, modifications can sometimes lead to:
- Increased wear and tear on engine components
- Potential decrease in fuel efficiency
- Need for additional tuning and adjustments
Conclusion
The real-world dyno results from the Stage 2 cam upgrade demonstrate the potential of the B-series engine to achieve impressive power gains. With an investment of $1,200, reaching 200 horsepower is not only feasible but also an exciting prospect for enthusiasts looking to enhance their vehicle’s performance. As with any modification, it’s crucial to consider all aspects, including maintenance and tuning, to ensure a balanced and enjoyable driving experience.
