The Nissan VQ35 engine has been a popular choice among car enthusiasts for its reliability and performance. When it comes to upgrading this engine, one of the most effective modifications is the installation of GSC Stage 2 camshafts. In this article, we will explore the performance gains of the VQ35 engine with GSC Stage 2 camshafts compared to the stock setup.
Understanding the VQ35 Engine
The VQ35 is a 3.5-liter V6 engine that has powered various Nissan and Infiniti models. Known for its smooth operation and robust power delivery, the VQ35 has a strong aftermarket support, making it a favorite among tuners. Its design allows for significant performance upgrades, particularly when it comes to camshaft modifications.
What are GSC Stage 2 Camshafts?
GSC Power-Division offers a range of performance camshafts designed to enhance engine performance. The Stage 2 camshafts are engineered to provide improved airflow, increased lift, and optimized timing. These camshafts are ideal for those looking to push their VQ35 engine beyond its stock capabilities.
Performance Gains with GSC Stage 2 Camshafts
When comparing the performance of the VQ35 with stock camshafts to those equipped with GSC Stage 2 camshafts, several key metrics illustrate the improvements:
- Horsepower Increase: The GSC Stage 2 camshafts can provide an increase of up to 30-40 horsepower over stock.
- Torque Improvement: Torque gains can reach 20-25 lb-ft, enhancing acceleration and throttle response.
- RPM Range: The camshafts allow for a higher RPM range, enabling the engine to produce power more effectively at elevated speeds.
Real-World Testing Results
To quantify the performance differences, real-world testing was conducted on a VQ35 engine with both stock and GSC Stage 2 camshafts. The results were impressive and highlighted the benefits of upgrading.
Testing Setup
The testing involved a controlled environment where both setups were tested on a dynamometer. The following parameters were measured:
- Peak horsepower
- Peak torque
- Power curve across the RPM range
- Throttle response characteristics
Results Overview
The stock VQ35 engine produced a peak horsepower of around 250 hp and peak torque of approximately 240 lb-ft. After installing the GSC Stage 2 camshafts, the engine showed a peak horsepower of 290 hp and a peak torque of 265 lb-ft. This represented a substantial improvement in both metrics.
Additional Benefits of Upgrading to GSC Stage 2 Camshafts
Beyond the raw power numbers, there are additional benefits to consider when upgrading to GSC Stage 2 camshafts:
- Improved Engine Efficiency: The enhanced airflow leads to better combustion efficiency, which can result in improved fuel economy under certain driving conditions.
- Enhanced Sound: Many enthusiasts appreciate the more aggressive engine sound that comes from upgraded camshafts.
- Better Throttle Response: The camshafts provide a more immediate throttle response, making the vehicle feel more lively and engaging to drive.
Considerations Before Upgrading
While the GSC Stage 2 camshafts offer significant performance gains, there are several considerations to keep in mind prior to upgrading:
- Compatibility: Ensure that your engine setup is compatible with the GSC Stage 2 camshafts, including supporting modifications such as upgraded valve springs and tuning.
- Tuning Requirements: Upgrading camshafts typically requires a retune of the engine management system to optimize performance.
- Potential for Increased Wear: More aggressive cam profiles can lead to increased wear on engine components, so regular maintenance is crucial.
Conclusion
In conclusion, upgrading to GSC Stage 2 camshafts on a VQ35 engine can yield substantial performance gains in horsepower and torque. The real-world testing results demonstrate the effectiveness of these camshafts, making them a worthwhile investment for enthusiasts looking to enhance their vehicle’s performance. However, potential buyers should carefully consider compatibility, tuning, and maintenance before proceeding with the upgrade.
