Get a pressure gauge with scale from zero to 2 bar, connect it
accordingtog,120and121.
Start up the engine, warm it up for a few minutes, then take it to
3000 rpm at the power NB.
The supercharge air pressure value to be measured is 89÷93
KPa (0.89÷0.93 bar).
If the setting pressure does not come within the required value
