The Nissan 370Z has long been a favorite among car enthusiasts, particularly for those looking to enhance performance through aftermarket modifications. Two popular options for increasing horsepower and torque are the Greddy Turbo Kit and the Stillen Supercharger. In this article, we will delve into the dyno results of both systems to see how they stack up against each other.
Understanding Forced Induction
Forced induction systems, such as turbochargers and superchargers, increase the amount of air entering the engine, allowing for more fuel to be burned and thus generating more power. While both systems aim to achieve similar results, they operate differently:
- Turbochargers: Utilize exhaust gases to spin a turbine, which compresses incoming air.
- Superchargers: Are mechanically driven by the engine’s crankshaft, providing immediate power without lag.
Greddy Turbo Kit Overview
The Greddy Turbo Kit is known for its ability to significantly increase horsepower and torque while maintaining reliability. It typically includes a turbocharger, intercooler, piping, and all necessary components for installation.
Power Gains
On the dyno, the Greddy Turbo Kit has shown impressive results. Depending on the tuning and supporting modifications, users have reported gains of:
- Up to 100 horsepower increase over stock.
- Torque gains reaching up to 80 lb-ft.
Stillen Supercharger Overview
The Stillen Supercharger is designed to provide a substantial power boost while maintaining a linear power delivery. This system is particularly favored for its ease of installation and minimal lag.
Power Gains
Dyno results for the Stillen Supercharger indicate that it can provide:
- Up to 90 horsepower increase over stock.
- Torque gains of approximately 70 lb-ft.
Comparative Dyno Results
When comparing the dyno results of the Greddy Turbo Kit and the Stillen Supercharger, it’s essential to consider not only the peak power numbers but also the characteristics of the power delivery.
- Greddy Turbo Kit: Offers higher peak horsepower and torque but may exhibit turbo lag.
- Stillen Supercharger: Provides a more immediate power delivery with slightly lower peak numbers.
Factors Influencing Performance
Several factors can influence the performance of both systems, including:
- Engine tuning: Proper tuning is crucial for maximizing gains.
- Supporting modifications: Upgrades to exhaust, intake, and fuel systems can enhance performance.
- Driving conditions: Environmental factors such as altitude and temperature can affect dyno results.
Conclusion
Both the Greddy Turbo Kit and the Stillen Supercharger offer significant power gains for the Nissan 370Z, each with its advantages and disadvantages. The choice between the two will largely depend on individual preferences regarding power delivery, installation complexity, and overall driving experience.
Ultimately, enthusiasts should consider their driving style and goals when deciding which forced induction system to install on their 370Z.
