Turbosmart TS-1 8280 Performance Turbocharger T4 1.24 A/R Externally Wastegated

The Turbosmart TS-1 8280 Performance Turbocharger is engineered for extreme horsepower applications where maximum airflow, reduced back pressure, and sustained high-load performance are critical. Utilizing advanced CFD-driven design, modern materials, and precision manufacturing techniques, the TS-1 series delivers a turbocharger that is smaller, lighter, and faster-responding than traditional large-frame alternatives—while maintaining exceptional durability.

This externally wastegated T4 1.24 A/R configuration is ideal for high-displacement engines, aggressive boost levels, and motorsport-focused builds that demand strong top-end power. Turbosmart’s proprietary dual ceramic bearing system and ultra-low rotating mass shaft assembly are paired with aggressive compressor aerodynamics to deliver impressive transient response for its size while maintaining strong efficiency at high shaft speeds and flow rates.

Every Turbosmart TS-1 turbocharger is supplied with essential installation hardware, including weld flanges, V-band clamps, and oil fittings, providing a premium, installation-ready solution backed by Turbosmart’s global motorsport pedigree.
