What is the purpose of the 1.12 A/R ratio?

The 1.12 A/R ratio on this turbine housing is designed to manage exhaust gas flow. A larger A/R like this one typically helps improve exhaust flow at higher engine speeds, which can lead to increased top-end horsepower.

What are the benefits of V-band connections?

V-band connections offer a secure and leak-free seal for the turbine housing. They also make installation and alignment easier compared to traditional bolt-on flanges, simplifying the setup process.

Can this turbine housing be used on any turbocharger?

This turbine housing is specifically designed to be paired with Garrett's G55 series turbochargers. Using it with other turbocharger models may not ensure proper fitment or optimal performance integration.

Product Details

This Garrett G55 Turbine Housing features a 1.12 A/R ratio and a T6 flange with V-band connections for both inlet and outlet. This specific A/R ratio is chosen to optimize exhaust flow for larger displacement engines or those seeking maximum top-end power, especially when paired with a larger compressor wheel. The V-band connections offer a secure and leak-free seal, simplifying installation and alignment compared to traditional bolt-on flanges.

Constructed from durable cast iron, this housing is built to withstand the high temperatures and pressures generated in demanding forced induction applications. The 1.12 A/R is a popular choice for builds aiming for high horsepower figures, as it allows the turbocharger to spool effectively while still providing ample flow at higher RPMs. This housing is designed to be paired with Garrett's G55 series turbochargers, ensuring proper fitment and performance integration. It's important to note that this part is not CARB approved and cannot be shipped to California.

When considering a turbine housing of this size and specification, it's crucial to match it with the appropriate engine management system and supporting modifications to achieve optimal performance and reliability. This housing is intended for custom turbocharger builds where precise control over the exhaust gas energy is paramount.
