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

The A/R ratio (Area to Radius) on a turbine housing dictates how much exhaust gas flows into the turbine wheel. A higher A/R like 1.30 generally allows for better exhaust flow at higher RPMs, supporting more top-end horsepower, while a lower A/R would spool faster but might restrict flow at higher engine speeds.

What vehicles or applications is this turbine housing intended for?

This turbine housing is specifically designed for S400 frame turbochargers, which are commonly used in high-performance and custom turbo builds for a wide range of vehicles. It's not a direct fit for all turbos, so confirm your turbocharger's frame size.

Does this turbine housing come with any hardware or gaskets?

This product listing is for the TiAL Sport BWVB99130-1.30 A/R S400 99mm Stainless Steel Turbine Housing only. Hardware and gaskets are typically sold separately and should be sourced according to the manufacturer's recommendations for your specific turbocharger assembly.

Product Details

What you get with this TiAL Sport BWVB99130-1.30 A/R S400 turbine housing is a well-built stainless steel component designed to house the turbine wheel for your S400-based turbocharger. This specific housing features a 99mm inducer diameter and a 1.30 A/R ratio, which is crucial for dictating exhaust gas flow and influencing turbo spool characteristics and top-end power delivery. The stainless steel construction means it's built to handle the extreme heat and corrosive exhaust gases found in high-performance applications without degrading over time.

Choosing the right A/R ratio is key when building a custom turbo system. A 1.30 A/R, like the one on this TiAL Sport housing, generally supports higher peak horsepower by allowing exhaust gases to flow more freely at higher RPMs. This makes it a popular choice for builds aiming for significant power gains, especially when paired with a suitable turbine wheel and the rest of your engine's setup. The material choice, high-grade stainless steel, ensures durability and resistance to cracking or warping under sustained high temperatures, which is a common failure point for lesser housings. This component is designed to fit S400 frame turbos, so ensure your existing or planned turbocharger uses this frame size for proper integration.

Keep in mind that this turbine housing is not CARB approved and cannot be shipped to California due to emissions regulations. For optimal performance and longevity, always refer to the manufacturer's installation guidelines and consider pairing it with other quality forced induction components to create a balanced and effective system.
