What does the 1.15 A/R ratio mean for performance?

The A/R ratio indicates the volume of the turbine housing's volute relative to its radius. A higher A/R, like 1.15, generally allows the turbocharger to flow more exhaust gas at higher RPMs, which can lead to improved top-end power.

Why is the V-band clamp connection beneficial?

The V-band clamp connection provides a strong, leak-free seal between the turbine housing and the turbocharger's exhaust manifold or adapter. It also makes installation and removal easier than traditional bolted flanges.

What are the restrictions for this part?

This turbine housing is not CARB approved and therefore cannot be shipped to California. It is intended for off-road use or in regions where emissions compliance is not required for this component.

Product Details

TiAL Sport is well-known for making high-performance turbocharger components, and this GT55 turbine housing is a prime example of their work. This particular housing features a 1.15 A/R ratio, which is a measure of the volume of the volute relative to its radius. A larger A/R like this one generally helps to improve top-end power by allowing the turbocharger to breathe more freely at higher engine speeds. It's designed to work with GT55-sized turbochargers, offering a solid option for builders looking to maximize airflow and power output.

Constructed from durable stainless steel, this turbine housing is built to withstand the extreme temperatures and pressures found in forced induction systems. The V-band clamp connection makes for a secure and leak-free seal, and it simplifies installation and removal compared to traditional bolt-on flanges. This design also helps to ensure a consistent fit and alignment with your turbocharger's compressor housing. If you're building a high-horsepower setup and need a robust turbine housing that can handle the demands, this TiAL Sport piece is a well-built choice.

This turbine housing is not CARB approved and cannot be shipped to California. Please ensure compatibility with your specific turbocharger and engine build before purchasing. Refer to the manufacturer's installation instructions for proper fitment and assembly details.
