Turbocharger
Charging pressure, min. values (measured in the engine’s inlet manifold at 100% load and wide open throttle (WOT), air
temperature approx. +25°C (77°F). When measuring at a different temperature, the charging pressure measured must be
corrected (see Workshop Manual).
If full power cannot be achieved, the pressure is considerably lower.
