Proprietary dual ceramic ball bearing system, oversized shaft hub with drastically improved oil sling, dual gas rings for improved gas sealing, optimised compressor backplate and compressor wheel integration for improved air management, tapered compressor wheels for increased strength, one piece integrated backplates for improved chassis rigidity. Turbosmart compressor housings are designed with velocity in mind to improve cylinder filling. Turbine housings are designed to compliemt Turbosmart's unique low pressure turbine wheel aerodynamics and reduce exhaust back pressure. 2618-T6 forged and CNC milled compressor wheels designed with aggressive aerodynamics leverage the ultra responsive bearing and shaft combination for increased airflow at all shaft speeds. Lightweight, aluminium compressor covers feature CFD drive and optimised A/R designs with anti-surge inlets, built-in speed and boost reference ports.
