What does the A/R ratio signify on this turbine housing?

The A/R ratio (Area/Radius) on a turbine housing indicates the size and shape of the exhaust gas passage. A 1.16 A/R, like on this housing, generally suggests a larger housing that can support higher horsepower by allowing more exhaust flow, while potentially slightly increasing turbo lag compared to a smaller A/R.

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 excellent resistance to high temperatures and corrosive exhaust gases, which helps prevent cracking and ensures a longer service life in demanding performance applications.

Are there any specific installation considerations for this part?

Proper sealing between the turbine housing, exhaust manifold, and the turbocharger's compressor housing is critical. Ensure all mating surfaces are clean and use appropriate gaskets or sealing methods to prevent exhaust leaks, which can negatively impact performance and efficiency.

Product Details

This is the TiAL Sport BWVB3745-1.16 A/R EFR 80mm stainless steel turbine housing, designed for high-performance forced induction setups. It's a crucial component for managing exhaust gas flow into the turbocharger's turbine wheel, directly impacting spool speed and overall power delivery. This housing is built to handle the extreme temperatures and pressures found in demanding turbocharged applications.

Constructed from durable stainless steel, this turbine housing offers excellent resistance to corrosion and thermal fatigue, ensuring longevity even under aggressive use. The 80mm A/R (Area/Radius) specification is carefully chosen to balance quick turbocharger spool-up with the ability to sustain high power levels. This specific A/R ratio is often selected for builds aiming for a broad powerband, providing a good compromise between low-end response and top-end flow. The precise internal geometry is key to optimizing exhaust gas velocity and directing it efficiently onto the turbine wheel, which is essential for maximizing turbocharger performance and responsiveness.

When installing this turbine housing, ensure it is properly mated to your turbocharger's compressor housing and exhaust manifold. Proper sealing is critical to prevent exhaust leaks, which can significantly reduce performance and efficiency. This component is intended for custom or performance-oriented turbocharger builds where precise control over exhaust flow and turbocharger characteristics is desired. Please note that this part is not CARB approved and cannot be shipped to California.
