What is the purpose of the 1.40 A/R ratio on this turbine housing?

The A/R ratio (Area/Radius) dictates the flow capacity of the turbine housing. A 1.40 A/R is a larger ratio, generally suited for applications seeking strong top-end power and efficient operation at higher engine speeds and boost levels. It influences how quickly exhaust gas can enter the turbine wheel.

What are the advantages of a V-band outlet compared to a traditional flange?

V-band outlets use a clamp system to secure the exhaust connection, which simplifies installation and removal. This design also tends to create a more consistent and leak-free seal under varying temperatures and pressures compared to bolted flanges.

Is this turbine housing compatible with any Garrett G55 turbine wheel?

This housing is designed to be part of the Garrett G55 series. While it features a T6 inlet and V-band outlet, you will need to ensure it is paired with the correct Garrett G55 turbine wheel and other turbocharger components specified by Garrett for your intended application.

Product Details

This Garrett G55 Turbine Housing features a 1.40 A/R ratio and a T6/V-Band inlet and outlet. This specific A/R ratio is chosen to help optimize exhaust gas flow into the turbine wheel, influencing how quickly the turbocharger spools up and at what engine speeds it can efficiently produce boost. The T6 flange is a common choice for larger turbochargers, offering a robust connection for high-flow exhaust systems, while the V-band outlet simplifies installation and ensures a secure seal compared to traditional bolted flanges.

The cast iron construction of this housing is well-suited for the high temperatures and pressures found in forced induction systems. Its robust build is designed to handle the demands of performance applications, providing a durable foundation for your turbocharger setup. This kit includes the turbine housing itself, ready to be paired with a compatible Garrett G55 turbine wheel and other necessary turbocharger components. Proper installation and exhaust manifold matching are key to realizing the full potential of this housing's airflow characteristics.

When building or upgrading a turbo system, selecting the correct turbine housing is critical for achieving your desired performance goals. This 1.40 A/R housing is typically suited for applications looking for strong top-end power and a broader powerband, especially when paired with larger displacement engines or higher boost levels. Always consult with your turbocharger specialist or refer to Garrett's application guides to ensure this housing is the right match for your specific engine and performance targets.
