What does 'reverse rotation' mean for this turbine housing?

Reverse rotation means the turbine wheel inside the turbo spins in the opposite direction of a standard turbocharger. This housing is specifically designed to match that opposite spin, which is often used in custom twin-turbo setups or specific engine configurations.

What is the benefit of a V-band connection?

The V-band connection uses a clamp to secure the housing, creating a very strong and leak-free seal. It's often easier to install and remove than traditional bolted flanges, and it can handle thermal expansion and contraction well.

What is the A/R ratio and why does 1.07 matter?

The A/R ratio (Area over Radius) indicates the size and flow characteristics of the turbine housing. A 1.07 A/R is a larger ratio, generally meaning it will flow more air at higher engine RPMs, helping the turbo maintain boost pressure and power throughout the rev range.

Product Details

Turbosmart is well-known for making high-performance engine components, especially for forced induction setups. This 70mm Kompact V-Band turbine housing is a prime example of their focus on precision and power. It's designed for reverse rotation applications, meaning it's built to work with turbos spinning in the opposite direction of standard rotation, which is crucial for certain twin-turbo or custom engine builds. The V-band connection offers a secure and leak-free seal, simplifying installation compared to traditional flanged setups.

This housing features a 1.07 A/R ratio, which is a measure of the turbine housing's efficiency and flow characteristics. A higher A/R like 1.07 generally means better flow at higher engine speeds, helping your turbocharger spool up effectively and maintain boost pressure throughout the powerband. It's constructed from durable cast iron, a material chosen for its ability to withstand the extreme temperatures and pressures found in a turbocharger system. This robust construction helps ensure longevity and consistent performance, even under demanding conditions. The 70mm inlet size is specific for certain turbocharger models, so it's important to confirm compatibility with your existing turbocharger setup.

When installing this turbine housing, remember that it's designed for specific reverse rotation turbochargers. Ensure you have the correct turbocharger model and that all V-band clamps and seals are properly seated for a secure fit. This part is not CARB approved and cannot be shipped to California. Always refer to your turbocharger manufacturer's installation guide for specific torque values and procedures.
