What is the A/R ratio of this turbine housing and what does it mean?

This housing has a 1.15 A/R ratio. The A/R (Area-to-Radius) ratio is a measurement of the turbine housing's volute shape. A larger A/R like 1.15 generally allows for more exhaust gas flow at higher engine speeds, which can help the turbocharger spool more efficiently and support increased horsepower.

What material is this turbine housing made from?

The turbine housing is constructed from durable cast iron. This material is chosen for its ability to withstand the extreme heat and pressure generated by exhaust gases in a turbocharging system.

Does this turbine housing come with installation hardware?

Typically, turbine housings are sold separately from gaskets and hardware. It is recommended to purchase new exhaust manifold gaskets and any necessary studs or bolts to ensure a proper seal and installation.

Product Details

This BorgWarner Air Werks turbine housing, specifically the 170310 model, is built for the Ford Power Stroke 7.3L NGD engine. It's designed to replace the stock housing on your TP38 turbocharger, offering a well-built component for those looking to upgrade or rebuild their forced induction system. The housing is constructed from durable cast iron, a material chosen for its ability to withstand the high temperatures and pressures generated by the turbocharger.

The Air Werks line from BorgWarner is known for its robust construction and performance-oriented design. This particular housing features a 1.15 A/R ratio, which is a critical measurement that affects how quickly the turbocharger spools up and how much airflow it can handle at higher RPMs. A larger A/R like this one generally supports better top-end power and flow, making it a popular choice for modified 7.3L Power Stroke engines that demand more from their turbo system. It's a solid option if you're looking to optimize your turbo's performance beyond stock specifications.

When installing this turbine housing, ensure you have the necessary gaskets and hardware, as they are not always included. It's also important to properly torque all fasteners according to the manufacturer's specifications to prevent exhaust leaks. This housing is intended for off-road use and is not CARB approved, meaning it cannot be legally shipped to California.
