What is the advantage of a ball bearing turbocharger?

Ball bearing center housings reduce friction compared to traditional journal bearings. This typically results in faster spool-up times and improved responsiveness, allowing the turbo to reach its boost threshold more quickly.

What does the 'A/R' rating on the turbine housing mean?

A/R stands for Area/Radius. It's a ratio that describes the size of the turbine housing's volute. A higher A/R, like the 1.01 on this unit, generally means a larger housing that can handle more exhaust flow at higher RPMs, reducing backpressure.

What is a V-band connection?

A V-band connection uses a clamp and a grooved flange to seal the exhaust housing to the turbine inlet. This setup is often preferred for its ease of installation, removal, and its ability to create a strong, leak-free seal compared to traditional bolt-on flanges.

Product Details

This HKS GT75115-BB turbocharger comes with a V-band inlet and a 1.01 A/R turbine housing. The V-band connection makes for a cleaner, more secure exhaust housing seal compared to traditional flanged setups, and it simplifies installation and removal. This unit is designed for high-performance applications where increased airflow and boost are desired.

The GT75115-BB features a ball bearing center housing, which helps the turbo spool up faster and reduces friction compared to journal bearing designs. This improved spool response means you get into your powerband quicker and maintain boost more consistently. The 1.01 A/R on the turbine housing is suited for engines that need to move a significant amount of exhaust gas, typically found in larger displacement or higher-revving performance builds. This housing choice helps prevent backpressure at higher RPMs, allowing the engine to breathe more freely.

When considering a turbocharger of this caliber, it's important to ensure your supporting systems are up to the task. This includes fuel delivery, engine management, and cooling. Proper tuning is essential to harness the full potential of this HKS turbo and maintain engine reliability. Please note that this turbocharger is not CARB approved and cannot be shipped to California.
