Construction & Design

The HKS Silent Hi-Power Turbocharger features a robust construction utilizing SUS304 stainless steel, which provides excellent resistance to heat and corrosion. Its one-piece turbine housing is precisely cast and TIG-welded for superior strength and durability. The turbine wheel is carefully balanced to minimize vibrations and ensure smooth operation at high RPMs. The compressor side is engineered with a high-efficiency wheel that maximizes airflow and boost response.

The incorporation of the "Silent Chamber" within the housing is a key design element that dampens lower-frequency noise, resulting in a quieter operation compared to traditional performance turbos. This chamber effectively reduces drone and resonance, making it more suitable for daily driving and long-distance cruising. The turbo's compact, aerodynamic design ensures minimal lag and quick spool, delivering a responsive driving experience.
