What is the A/R ratio and why does it matter?

The A/R ratio, or area-to-radius ratio, describes the size of the turbine housing's internal passages. A higher A/R like 1.45 generally means larger passages, which helps reduce exhaust backpressure and allows the turbocharger to breathe better at higher RPMs, leading to improved top-end power.

What are the benefits of a V-band clamp connection?

V-band connections offer a strong, leak-free seal and are often easier to install and remove than traditional bolted flanges. This makes maintenance or swapping components like the turbine housing more straightforward.

What is the advantage of stainless steel for a turbine housing?

Stainless steel is chosen for turbine housings because it offers excellent resistance to the extreme heat and corrosive exhaust gases produced by an engine. This durability helps ensure a longer service life for the component under demanding conditions.

Product Details

TiAL Sport is well-known for making robust performance turbocharger components, and this GT55 turbine housing is a prime example of their work. This housing is built for high-flow applications, featuring a 1.45 A/R ratio that helps optimize exhaust gas flow into the turbine wheel for improved turbocharger response. The V-band clamp connection makes for a secure and leak-free seal, and it simplifies installation and removal compared to traditional bolted flanges. It's constructed from durable stainless steel, which is chosen for its ability to withstand the high temperatures and corrosive exhaust gases found in performance engine setups.

This specific housing is designed to work with the GT55 size turbine wheel, a popular choice for serious performance builds where significant airflow is needed. The 1.45 A/R (area-to-radius) ratio is on the larger side, meaning it's best suited for engines that produce a lot of exhaust volume, typically at higher RPMs. This helps prevent backpressure from building up too much, allowing the turbo to spool more efficiently and make more power. The stainless steel construction offers good resistance to heat and corrosion, which is crucial for longevity in demanding applications.

When installing this turbine housing, remember that it utilizes a V-band clamp system for attachment to the turbocharger's compressor outlet. Ensure you have the correct V-band clamp and mating flange, which are typically sold separately. Due to its performance-oriented design and materials, this part is not CARB approved and cannot be shipped to California.
