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.
