What is the significance of the 0.72 A/R on the turbine housing?

The 0.72 A/R (area-to-radius ratio) on the turbine housing helps determine the turbocharger's performance characteristics. A 0.72 A/R generally provides a good balance, allowing for relatively quick spool-up while still supporting significant airflow for higher horsepower outputs.

What does 'O/V V-Band / V-Band' mean for installation?

This indicates that both the inlet and outlet connections on the turbine housing use V-band clamps. This type of connection is known for being easier to install and providing a more robust, leak-free seal compared to traditional flanged connections.

What are the implications of this turbocharger not being CARB approved?

If a part is not CARB approved, it means it has not been tested and certified by the California Air Resources Board for emissions compliance. Consequently, this turbocharger cannot be legally shipped to or installed on vehicles registered in California.

Product Details

Garrett is well-known for their advanced turbocharger technology, powering race cars and high-performance street vehicles for decades. This G25-550 turbocharger is a prime example of their expertise, built for enthusiasts looking to significantly increase their engine's power output. It features a V-band connection for both the turbine inlet and outlet, which simplifies installation and ensures a strong, leak-free seal compared to traditional flanged connections. The internal wastegate setup is also designed for ease of integration into many custom applications.

This particular model boasts a 0.72 A/R (area-to-radius ratio) turbine housing. This A/R value is a key spec that influences how quickly the turbocharger spools up and where its peak efficiency lies. A 0.72 A/R generally offers a good balance, allowing for relatively quick response while still supporting substantial airflow for higher horsepower levels, often targeting around 550 horsepower as the name suggests. The G25 series also incorporates advanced aerodynamics in its compressor and turbine wheels, contributing to improved airflow and durability. The internal wastegate is pre-set to help manage boost pressure, making it a more straightforward option for builders who don't require external wastegate plumbing.

When considering a turbocharger of this caliber, it's important to remember that it's part of a larger system. You'll need to ensure your engine's fuel system, cooling, and exhaust can support the increased airflow and power. This turbocharger is not CARB approved and cannot be shipped to California. Always consult with a professional or refer to detailed build guides for proper installation and tuning to get the most out of this performance component.
