- Efficiency Rating: 76% at peak
This turbocharger is designed for high-performance applications and is capable of producing significant power while maintaining good efficiency. The Precision 6466 is particularly well-suited for applications where quick spool-up and high RPM performance are desired.
Garrett GTX 3584RS Overview
The Garrett GTX 3584RS is another excellent choice for achieving 650 horsepower. Its specifications include:
- Compressor Wheel Size: 68mm
- Turbine Wheel Size: 64mm
- AR: 0.83
- Max Boost: 30 psi
- Efficiency Rating: 78% at peak
This turbocharger is designed with advanced aerodynamics, providing excellent response and power delivery. The GTX 3584RS is particularly favored in applications where higher boost levels are achievable, making it a strong contender for those looking to maximize their horsepower output.
Comparative Analysis
When comparing the Precision 6466 and the Garrett GTX 3584RS, several factors come into play:
- Compressor Size: The GTX 3584RS has a slightly larger compressor wheel, which may provide better airflow at higher RPMs.
- Turbine Size: The Precision 6466 has a smaller turbine wheel, which can lead to faster spool times.
- Efficiency: Both turbos have high efficiency ratings, but the GTX 3584RS edges out slightly in peak efficiency.
- Response: The Precision 6466 may respond quicker due to its smaller turbine size, making it favorable for street applications.
- Power Delivery: The GTX 3584RS is likely to provide a broader power band, especially at higher RPMs.
Choosing the Right Turbo for Your Build
Deciding between the Precision 6466 and the Garrett GTX 3584RS ultimately depends on your specific goals and vehicle setup. Consider the following factors:
- Intended Use: If you plan to use your vehicle primarily on the street, the Precision 6466 may offer better drivability and quicker spool.
- Boost Levels: If your setup allows for higher boost levels and you want maximum power, the GTX 3584RS could be the better option.
- Engine Configuration: Ensure that your engine can support the chosen turbo’s airflow and boost levels effectively.
- Budget: Consider the cost of the turbocharger, along with any additional components needed for installation.
Conclusion
Both the Precision 6466 and the Garrett GTX 3584RS are excellent choices for achieving 650 horsepower. Understanding your specific needs and how each turbocharger aligns with your goals will help you make the best decision. Whether you prioritize quicker spool times or higher peak power, either option can deliver impressive results when properly matched with your engine setup.
