When it comes to enhancing the performance of your diesel engine, selecting the right turbo setup is crucial. Among the various options available, the Garrett GT37 and GT35 compound turbo setups stand out for their efficiency and power potential. This article will guide you through the considerations and choices involved in selecting the right Garrett compound turbo setup for your diesel build.
Understanding Compound Turbocharging
Compound turbocharging involves using two or more turbochargers to improve the overall performance of an engine. This setup allows for better airflow, increased boost pressure, and improved efficiency, especially in high-performance applications. The Garrett GT37 and GT35 turbos are popular options due to their robust design and ability to handle significant power levels.
Key Factors to Consider
- Engine Size: The displacement of your engine plays a significant role in determining the appropriate turbo setup.
- Power Goals: Define your horsepower and torque targets to guide your turbo selection.
- Driving Style: Consider whether your build is for daily driving, racing, or towing, as this will influence your turbo choice.
- Boost Pressure: Understand the boost levels your engine can handle and how the turbo setup will achieve those levels.
Garrett GT37 vs. GT35: Specifications
Both the GT37 and GT35 turbos have distinct specifications that cater to different performance needs. Here’s a breakdown of their key features:
- GT37:
- Compressor Wheel Diameter: 76mm
- Max Horsepower: Up to 700 HP
- Ideal for larger displacement engines
- GT35:
- Compressor Wheel Diameter: 70mm
- Max Horsepower: Up to 600 HP
- Suitable for medium displacement engines
Choosing the Right Setup
When deciding between the GT37 and GT35, consider the following:
- Application: For high-power builds, the GT37 may be more suitable, while the GT35 is ideal for moderate power needs.
- Compatibility: Ensure the turbo you choose fits well with your existing engine components and setup.
- Budget: Factor in the cost of the turbo, installation, and any additional components needed for optimal performance.
Installation Considerations
Proper installation is critical for maximizing the performance of your compound turbo setup. Here are some considerations to keep in mind:
- Turbo Placement: Ensure adequate space for both turbos and proper airflow.
- Intercooling: Invest in a quality intercooler to manage the increased heat generated by the turbos.
- Exhaust Routing: Plan your exhaust routing to minimize back pressure and improve turbo response.
- Fuel System: Upgrade your fuel system to support the increased demand for fuel at higher power levels.
Tuning for Performance
After installation, proper tuning is essential to ensure your diesel build runs efficiently and reliably. Work with a knowledgeable tuner who understands compound turbo setups to achieve the best results.
Conclusion
Choosing the right Garrett GT37 or GT35 compound turbo setup for your diesel build can significantly enhance performance. By considering your engine size, power goals, and installation requirements, you can make an informed decision that will lead to a successful build. Remember to prioritize proper installation and tuning to maximize the benefits of your turbo setup.
