Turbocharged downsized gasoline direct injection engine is one of promising technologies in the automotive industry. However reduction in turbo-lag under transient operation was one of important challenging point to improve drivability. Engine transient performance was investigated in a 4-cylinder 2.0 L turbo-gasoline direct injection(T-GDI) engine using Inconel and TiAl turbochargers. The TiAl turbocharger performed superior transient boost pressure and torque rises under various engine transient operation condition. These were mainly due to lower rotational inertia of TiAl turbocharger. The Maximum boost pressure and torque build up were founded in 1500 rpm and 2000 rpm, instant load change from 20% to 100% of pedal position.
