SX and SX-E Turbochargers, Designed to Race

Developed as a joint effort between BorgWarner and GM’s in-house racing program in 2004, AirWerks turbochargers were designed to create reliable and consistent boost for GM’s Pro FWD (front-wheel drive) sport compact racecars.

The AirWerks SX and SX-E incorporate serviceable twin hydrodynamic journal bearings with a high-pressure ratio compressor stage utilizing extended-tip technology and a high-efficiency turbine stage.

Power Range

Faster spool-up at lower engine speeds. Powerful boost for top-end performance.
Innovative extended-tip technology delivers the increased airflow of a larger compressor wheel with the lower mass of a smaller, low-inertia wheel.

Dimensional Reference

Engineered specifically for drag racing, pulling and road racing, AirWerks turbochargers have earned a reputation as robust, brute-force boosting devices.
