What does the 0.85 A/R ratio mean for my turbo?

The 0.85 A/R (area-to-radius) ratio on this turbine housing influences how quickly your turbocharger spools up. A lower A/R like 0.85 generally helps the turbo build boost pressure faster, leading to quicker throttle response.

What material is this turbine housing made from?

This turbine housing is constructed from cast iron, a material chosen for its ability to withstand the high temperatures and pressures generated in forced induction applications.

What is the benefit of V-band connections?

V-band connections on both the inlet and outlet provide a strong, leak-free seal. They also make installation and removal of the housing simpler compared to traditional flange-and-bolt methods.

Product Details

This Garrett G40 turbine housing features a 0.85 A/R ratio and a V-band inlet and outlet. This specific A/R (area-to-radius) ratio is a key factor in determining how quickly your turbocharger spools up and where its power band will be. A lower A/R, like this 0.85, generally helps the turbocharger build boost pressure faster, making it ideal for applications where quick throttle response is a priority.

Constructed from durable cast iron, this housing is built to withstand the high temperatures and pressures associated with forced induction systems. The V-band connections on both the inlet and outlet offer a secure and leak-free seal, while also simplifying installation and removal compared to traditional flange-and-bolt setups. This kit includes everything needed to install the turbine housing onto your Garrett G40 turbocharger, ensuring a straightforward integration into your existing setup. It's designed to work with the Garrett G40 turbocharger series, allowing you to fine-tune your engine's performance characteristics.

When considering this housing, remember that it is not CARB approved and cannot be shipped to California. For optimal performance and longevity, ensure your engine's fueling and tuning are adjusted to match the increased airflow and boost potential this housing enables. Proper exhaust manifold matching is also crucial for maximizing efficiency and preventing backpressure issues.
