Choosing the Right Garrett Gtr Series Turbo for Your 700 Hp Drag Car

by

When it comes to building a 700 HP drag car, selecting the right turbocharger is crucial for maximizing performance and efficiency. The Garrett GTR Series offers a range of options that cater to high-performance applications. In this article, we will explore how to choose the right Garrett GTR Series turbo for your drag car.

Understanding the Garrett GTR Series

The Garrett GTR Series is designed for high-performance engines, providing exceptional boost and efficiency. These turbos are engineered to withstand the rigors of drag racing and deliver the power needed for competitive performance.

Key Factors to Consider

  • Engine displacement and configuration
  • Desired power output
  • Boost pressure
  • Turbo sizing
  • Application-specific needs

Engine Displacement and Configuration

Understanding your engine’s displacement and configuration is essential. Different engines have unique characteristics that affect how they respond to turbocharging. For a 700 HP build, consider the following:

  • V8 engines typically require larger turbos compared to smaller engines.
  • Inline engines may have different spool characteristics.

Desired Power Output

Your target power output will influence your turbo choice. For a 700 HP drag car, you need to select a turbo that can efficiently support this power level without compromising reliability.

Boost Pressure

Boost pressure is a critical factor in turbocharging. Higher boost levels can lead to increased power but also require careful tuning and engine management. Determine the boost pressure that your engine can handle safely while achieving your performance goals.

Selecting the Right Turbo Size

Turbo sizing is essential for achieving the desired performance characteristics. A turbo that is too small may limit your power potential, while one that is too large may result in lag and poor throttle response. Here are some tips for selecting the right size:

  • Check the compressor map for efficiency ranges.
  • Consider the turbine housing size for optimal exhaust flow.
  • Garrett GTR 35: Ideal for high RPM applications.
  • Garrett GTR 40: Provides excellent boost response and power.
  • Garrett GTR 45: Suitable for extreme power builds.

Garrett GTR 35

The GTR 35 turbocharger is a popular choice for those looking to hit the 700 HP mark. It offers a good balance of spool time and power delivery, making it suitable for both street and drag applications.

Garrett GTR 40

With a slightly larger compressor and turbine, the GTR 40 is designed for those who want more top-end power. It excels in high RPM scenarios, making it a great choice for dedicated drag racing setups.

Garrett GTR 45

The GTR 45 turbocharger is for extreme builds aiming for maximum horsepower. It provides the airflow necessary to support high power levels while maintaining efficiency.

Conclusion

Choosing the right Garrett GTR Series turbo for your 700 HP drag car involves understanding your engine’s needs, desired performance, and the specific characteristics of each turbo. By considering these factors, you can make an informed decision that will enhance your drag racing experience.
