What is the A/R ratio and why does it matter?

The A/R ratio, or Area/Radius ratio, on a turbine housing affects how the turbocharger spools up and makes power. A lower A/R (like 1.16) generally helps the turbo spool faster, improving low-end response, while a higher A/R allows for more top-end power at the expense of some initial responsiveness.

What are the benefits of a V-band clamp connection?

V-band clamps create a strong, leak-free seal and are often easier to install and remove than traditional bolted flanges. This makes maintenance or component swaps more straightforward and helps prevent exhaust leaks.

Is this turbine housing compatible with all turbochargers?

This specific turbine housing is designed for TiAL Sport GT42 turbocharger applications. You will need to ensure your turbocharger's turbine wheel and mounting flange are compatible with this housing's specifications and V-band connection.

Product Details

TiAL Sport is well-known for making robust turbocharger components, and this GT42 turbine housing is a prime example of their work. It's built for high-performance forced induction setups where reliability and consistent flow are critical. This particular housing features a 1.16 A/R ratio, which is a good balance for many applications looking for strong top-end power without sacrificing too much low-end response. The V-band clamp connection makes for a secure and leak-free seal, simplifying installation and maintenance compared to traditional bolt-on flanges.

Constructed from durable stainless steel, this housing is designed to withstand the extreme temperatures and pressures found in a turbo system. The stainless steel material offers good resistance to corrosion and thermal fatigue, ensuring it holds up over time. The 1.16 A/R is a versatile choice, often paired with larger turbocharger wheels to help them spool efficiently while still allowing for significant airflow at higher RPMs. This housing is a key component for anyone building or upgrading a custom turbo system and looking for a well-made part from a reputable manufacturer.

When installing this turbine housing, ensure you have the correct V-band clamp and mating flange for your turbocharger's turbine wheel. Proper sealing is crucial for performance and longevity. This part is not CARB approved and cannot be shipped to California.
