AirWerks involvement in the sport compact arena created a BorgWarner first… a purpose built, engineered for performance only, production turbocharger. While all BorgWarner turbos, including the “SX”, receive a full nomenclature designating content detail of the unit; the AirWerks team decided to construct these units differently and retain the “SX” suffix, which is fitting for a unit with racing heritage and designed for excitement.
The S400SX is a serviceable twin hydrodynamic journal bearing turbo that excels due to a high-pressure ratio compressor stage utilizing extended-tip technology and a high efficiency turbine stage. This specialized turbo configuration provides ultra-fast response and more than 70 PSI of boost and if the AirWerks team has anything to do with it, it will continue to well into the future.
A new series of the S400SX turbos were designed specifically to bolt-into existing high performance applications and offer numerous unique turbine housing configurations for a variety of application requirements. Although the BorgWarner sponsored race teams still receive special attention and unique combinations, please know that the units which are now available and known as the “SX” series have a racing heritage in their oil galleries and owe their existence to the sport.
