What does the .16 A/R ratio mean for my turbo?

The A/R ratio, or Area/Radius, describes the size of the turbine housing's volute. A .16 A/R is considered a smaller ratio, which generally leads to quicker turbocharger spool-up and improved low-end response. This can help your engine reach boost pressure sooner.

What is the advantage of a stainless steel turbine housing?

Stainless steel offers excellent resistance to corrosion and can withstand the extreme heat generated by exhaust gases in a turbo system. This material choice contributes to the housing's longevity and structural integrity under demanding operating conditions.

What is the difference between this and a larger A/R housing?

A larger A/R housing, for example .80 A/R, would typically allow for more top-end power by letting exhaust gases flow more freely at higher RPMs. However, it would likely result in slower turbo spool and less low-end torque compared to this .16 A/R housing.

Product Details

This 80mm stainless steel turbine housing from TiAL Sport is built for the SXE9180 S300 turbocharger. It features a .16 A/R ratio, which is a key factor in how the turbo spools up and delivers boost. A smaller A/R like this generally means quicker spool, getting you into boost sooner, while a larger A/R typically means more top-end power. The choice of .16 A/R is often selected for applications where a balance between quick response and strong mid-range power is desired.

Constructed from durable stainless steel, this housing is designed to withstand the high temperatures and pressures found in forced induction systems. Stainless steel offers good corrosion resistance and maintains its structural integrity under extreme heat cycles. The BWVB3745-1.16 designation indicates specific internal dimensions and porting designed to work optimally with the SXE9180 turbine wheel, ensuring efficient exhaust gas flow into the turbine. This housing is a direct replacement for the stock unit on compatible turbochargers, making installation straightforward for those familiar with turbocharger assembly.

When building or upgrading a forced induction system, selecting the right turbine housing is critical for achieving your desired performance goals. This TiAL Sport housing offers a well-built option for tuners and enthusiasts looking to fine-tune their turbocharger's response characteristics. Please note that this part is not CARB approved and cannot be shipped to California.
