TiAL Sport BWVB91145-1.45 A/R S400 91mm Stainless Steel Turbine Housing

This stainless steel turbine housing from TiAL Sport is built for the S400 frame turbocharger, featuring a 91mm compressor wheel and a 1.45 A/R ratio. The A/R, or area-to-radius ratio, dictates how much exhaust gas flows into the turbine wheel. A higher A/R like 1.45 generally means better flow at higher RPMs, helping your turbocharger spool up effectively and maintain boost in the upper powerband. This makes it a solid choice for builds focused on top-end power and sustained performance.

Crafted from durable stainless steel, this housing is designed to withstand the high temperatures and pressures associated with forced induction. The material choice helps resist corrosion and thermal fatigue, ensuring longevity even under demanding conditions. TiAL Sport is known for its well-built components, and this turbine housing is no exception, offering a reliable foundation for your custom turbo setup. It's designed to fit the S400 frame, providing a direct replacement or upgrade path for compatible turbochargers.

When building a high-performance engine, the turbine housing plays a critical role in how your turbocharger performs across the entire RPM range. This 1.45 A/R housing is particularly suited for applications where maximizing high-RPM power is the goal. Please note that this part is not CARB approved and cannot be shipped to California. Always consult with your turbocharger manufacturer or a qualified professional to ensure this housing is the correct match for your specific turbocharger and build goals.
