Maximum torque of 250 Nm [185 ft-lbs] is available at a constant boost pressure of 0.85 bar [12.3 PSI] between 1950 and 5600 rpm. Peak power of 200 hp is reached at 5600 rpm.
...
At full throttle, the engine's electronic management system provides additional reserves by allowing a maximum rpm of 6800 instead of 6400 for a short period. Clever packaging of the turbo system is the basis for its turbine-like performance; exhaust manifold, turbine housing, waste gate and other elements are integrated as a single, compact component, allowing Vauxhall engineers to significantly reduce engine size and weight.

This state of the art Euro 4 compliant turbo engine proves that performance needn't result in high fuel consumption - on the combined cycle, the Astra GSi manages 31.7mpg.

I got that straight from the Vauxhall website. According to them the current Astra SRi 2.0L Turbocharged ECOTEC making 200HP delivers all 185 ft-lbs at 1950 RPM. I'm betting the max Torque RPM is higher on the 240HP version due to more then likely a larger Turbocharger, but I'm not too picky if Max Torque of 236 ft-lbs was available ~2400 RPM. As we've discussed the ECOTEC VVT 2.4L only makes 90% at 2400RPM.
