What is the significance of the 1.24 A/R ratio on the turbine housing?

The A/R ratio (Area/Radius) of the turbine housing affects how the turbocharger spools up and performs at higher RPMs. A 1.24 A/R is a larger housing, generally suited for higher horsepower applications and will typically result in later but stronger top-end power delivery compared to smaller A/R ratios.

What are the essential supporting modifications needed for this turbocharger?

Installing this turbocharger will likely require upgrades to your fuel system, engine management tuning, and exhaust system to handle the increased airflow and power. Proper oil and coolant lines are also critical for the turbo's longevity and performance.

What does 'externally wastegated' mean for this turbocharger?

An externally wastegated turbocharger uses a separate wastegate actuator that is mounted on the exhaust manifold or the turbocharger's turbine housing. This setup generally offers more precise boost control and better flow management compared to internal wastegates, helping to prevent overboost.

Product Details

The Turbosmart TS-1 Turbocharger features a 1.24 A/R turbine housing with a T4 exhaust flange, a key specification for managing exhaust gas flow and determining spool characteristics. This externally wastegated unit is built for high-performance applications where precise boost control is essential. Its robust construction is designed to handle the demands of serious engine builds, offering a significant upgrade over stock turbochargers for those looking to increase power output.

This turbocharger utilizes a durable cast iron turbine housing and a forged-milled aluminum compressor wheel, balancing heat resistance with lightweight performance. The internal wastegate actuator is precisely calibrated to maintain stable boost pressure, preventing overboost conditions and ensuring consistent power delivery. The T4 flange provides a common mounting point for many aftermarket exhaust manifolds, simplifying installation into custom setups. Its design focuses on delivering improved airflow and responsiveness, making it a solid choice for tuners and builders aiming for substantial power gains.

When considering a turbocharger of this caliber, it's important to ensure your engine's supporting systems are up to the task. This includes proper fuel delivery, engine management tuning, and an exhaust system capable of handling the increased flow. Proper oil and coolant lines are also critical for longevity and optimal performance. Consult with your engine builder or tuner to confirm all necessary components for your specific application.
