Stellantis’s Street and Racing Technology (SRT) division has engineered a new forced-induction concept called eBoost Air, designed to give large turbochargers the instant throttle response of a mechanical supercharger or an electric motor setup. According to reports from Road & Track and Jalopnik, the technology addresses traditional turbo lag by utilizing an electronically controlled air injection system to spool the turbocharger instantly.
How SRT eBoost Air Works
The eBoost Air system tackles the inherent delay of large turbochargers by injecting compressed air directly into the turbine housing or intake stream on demand. According to technical details outlined by Top Speed, this compressed air forces the turbine blades to spin up immediately when the driver demands power, bypassing the traditional exhaust-gas pressure build-up phase. The setup bridges the gap between massive top-end horsepower and low-end throttle response, mimicking the immediate torque delivery typically associated with a positive-displacement supercharger.
Application and Performance Implications
Traditional large turbos on inline-six platforms often require a noticeable pause before delivering peak boost. By integrating the eBoost Air system, the engine gains immediate boost pressure, resulting in a driving dynamic that mirrors a high-displacement V-8 engine.
