What does the A/R ratio mean for this turbine housing?

The A/R (Area to Radius) ratio of 87.5mm indicates the size and shape of the exhaust gas passage into the turbine wheel. A higher A/R like this one generally helps support more airflow at higher engine RPMs, contributing to peak power, while still aiming for a balance with spool characteristics.

What material is this turbine housing made from and why is it important?

This housing is made from stainless steel. This material is chosen for its ability to withstand the extreme heat and corrosive exhaust gases produced by performance engines, helping to ensure long-term durability and structural integrity.

What is required to install this turbine housing?

Installation typically involves mating this housing to a compatible turbine wheel and exhaust manifold. Proper sealing and secure fastening are crucial. It is recommended to consult the specific turbocharger manufacturer's guidelines or a professional installer for detailed procedures.

Product Details

When you're building a high-performance forced induction system, the turbine housing plays a critical role in how your turbocharger spools and delivers power. This TiAL Sport BWVB3745-102 turbine housing is specifically designed for S400-based turbochargers, featuring an 87.5mm A/R ratio. This specific A/R is chosen to balance quick spool-up with the ability to support significant airflow at higher engine speeds, making it a popular choice for builds aiming for substantial power gains.

Crafted from durable stainless steel, this housing is built to withstand the extreme temperatures and pressures found in performance exhaust systems. The material choice helps resist corrosion and maintain structural integrity over time, even under demanding conditions. TiAL Sport is well-known for its focus on performance and reliability, and this turbine housing reflects that commitment. Its precise casting and smooth internal A/R profile are designed to optimize exhaust gas flow into the turbine wheel, contributing to improved turbocharger efficiency and responsiveness.

This turbine housing is intended for custom turbocharger builds and requires careful consideration of the entire system, including the turbine wheel, compressor housing, and exhaust manifold. Ensure compatibility with your specific turbocharger frame and manifold design before installation. Please note that this part is not CARB approved and cannot be shipped to California.
