HKS GT75115-BB V band A/R 1.15

The HKS GT75115-BB turbocharger features a 1.15 A/R turbine housing, a critical spec that dictates exhaust gas flow and influences spool characteristics. This particular housing size is chosen to balance quick response with the ability to sustain high boost levels, making it suitable for builds aiming for significant power gains. HKS is well-known for its performance tuning parts, and this turbocharger is built with their signature attention to detail.

This turbocharger utilizes a V-band connection for the turbine housing, which offers a more compact and robust mounting solution compared to traditional multi-bolt flanges. This design can simplify installation and ensure a secure seal under high exhaust pressure. The internal components are selected for durability and performance under demanding conditions, reflecting HKS's extensive experience in motorsport and performance vehicle development. While specific internal compressor and turbine wheel dimensions are proprietary, the overall design aims to provide an improved airflow path for both intake and exhaust gases.

When considering a turbocharger of this caliber, it's important to note that it is not CARB approved and cannot be shipped to California due to emissions regulations. Proper supporting modifications, such as an upgraded fuel system, engine management tuning, and potentially an intercooler and exhaust system, are essential to safely and effectively utilize the power potential of this turbocharger. It is recommended to consult with a professional tuner to ensure optimal performance and engine longevity.
