What does the A/R ratio mean for this turbine housing?

The A/R ratio, in this case 1.39, refers to the Area/Radius of the volute housing. A larger A/R like 1.39 is generally used for engines that produce more exhaust gas volume, helping to reduce backpressure at higher RPMs and allowing the turbo to spool more efficiently for sustained boost.

What type of connection does this housing use?

This turbine housing uses a T6 V-band connection for both the inlet and outlet. This is a common and robust standard for high-flow turbocharger setups, ensuring a secure and leak-free seal.

Is this turbine housing compatible with all Garrett turbos?

No, this specific turbine housing is designed for the Garrett G47 series turbochargers. It is important to confirm that your turbocharger model is a G47 and uses the T6 V-band connection before purchasing.

Product Details

This is the Garrett G47 Turbine Housing Kit, featuring a 1.39 A/R ratio and a T6 V-band inlet and outlet. This component is crucial for managing exhaust gas flow into the turbine wheel of your turbocharger, directly influencing boost response and overall power delivery. It's designed for high-performance applications where precise control over exhaust energy is needed to spool the turbocharger efficiently.

The 1.39 A/R (Area/Radius) ratio is on the larger side, meaning it's intended for engines that produce a significant amount of exhaust gas volume, typically found in larger displacement or highly modified engines. A larger A/R helps to reduce backpressure at higher RPMs, allowing the turbo to breathe more freely and sustain boost levels more effectively. The T6 V-band connection is a robust and common standard for high-flow turbocharger setups, ensuring a secure and leak-free seal for the exhaust manifold to turbine housing connection. This housing is built to handle the extreme temperatures and pressures associated with forced induction systems.

When selecting a turbine housing, the A/R ratio is a key factor in matching the turbocharger's performance characteristics to your engine's specific needs. This Garrett housing is a well-built option for those looking to fine-tune their turbo system for maximum efficiency and power, especially in applications that demand high exhaust flow. Please note that this part is not CARB approved and cannot be shipped to California.
