TURBOCHARGER PRESSURE TESTING Install a 0-2bar pressure gauge at position(A) after removing the existing plug. Start the engine and operate at low idle for five(5) minutes to allow warm-up. Increase the engine speed to 3000 r/min or 3600 r/min (depending on engine specification while applying full Nb load to the engine). See page 10 for the power output curve. The gauge pressure, at full speed, full load, should be 0.87-0.91 bar. If the pressure setting does not reach specification, adjust the turbocharger waste gate as is defined on page 48.
