TiAL Sport BWVB99117-1.17 A/R S400 99mm Stainless Steel Turbine Housing

This is the TiAL Sport BWVB99117-1.17 A/R S400 99mm stainless steel turbine housing. It's built for high-performance forced induction setups, specifically designed to house the turbine wheel for an S400-based turbocharger. The 99mm housing is sized to work with a 99mm turbine wheel, and the 1.17 A/R ratio helps manage exhaust gas flow to optimize boost response and overall power delivery for demanding applications.

Crafted from durable stainless steel, this housing is built to withstand the extreme temperatures and pressures found in performance turbo systems. Stainless steel offers good corrosion resistance and maintains its structural integrity under heat. The precise A/R ratio is crucial for tuning; a lower A/R generally leads to quicker spool-up, while a higher A/R can help extend the powerband at higher RPMs. This 1.17 A/R is a popular choice for applications looking for a balance between responsiveness and top-end power.

When installing a turbine housing like this, ensure it's properly mated to your compressor housing and exhaust manifold. Proper sealing is critical to prevent exhaust leaks, which can significantly impact performance and efficiency. This part is not CARB approved and cannot be shipped to California.
