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

The A/R ratio on the turbine housing is 1.10. This ratio helps determine the flow rate of exhaust gases through the turbine. A higher A/R like 1.10 generally allows for better exhaust flow at higher engine speeds, which can help reduce backpressure and improve turbo efficiency in demanding applications.

What does the 71.4mm inducer diameter refer to?

The 71.4mm inducer diameter refers to the measurement of the compressor wheel at its widest point where air enters. This spec is a key indicator of the turbocharger's potential airflow capacity, directly influencing how much air it can push into your engine for increased power.

What are the implications of this turbocharger not being CARB approved?

This turbocharger is not CARB (California Air Resources Board) approved. This means it cannot be legally shipped to or installed on vehicles registered in California due to emissions regulations. It is important to verify local emissions laws before purchasing and installing this part.

Product Details

BorgWarner is well-known for their robust and reliable turbochargers, and the S400SX3 series continues that tradition. This particular unit, part number 177248, is built for serious performance applications where increased airflow and boost are critical. It features a T4 turbine housing with an A/R ratio of 1.10, which is ideal for managing exhaust gas flow in higher-output engines. The compressor side has a 71.4mm inducer diameter, meaning it can move a significant amount of air to help your engine make more power.

This turbocharger is designed for enthusiasts looking to significantly upgrade their vehicle's forced induction system. The S400SX3 line is popular for its durability and ability to handle demanding conditions. The 1.10 A/R housing helps to reduce exhaust backpressure, allowing the turbo to spool more efficiently and maintain boost levels at higher RPMs. The 71.4mm inducer on the compressor wheel is a key spec that indicates its airflow capacity, crucial for achieving substantial power gains when properly matched with your engine's needs and supporting modifications.

When installing a turbocharger of this caliber, it's important to ensure your engine is properly prepared. This includes having adequate fuel delivery, cooling, and exhaust systems to support the increased airflow and power. Proper oil supply and drain lines are also essential for the longevity of the turbo. Please consult the manufacturer's installation guide for specific details regarding fitment and setup, as this unit is not CARB approved and cannot be shipped to California.
