[Vwdiesel] Turbo-determining if it's working or not ?

[Nate Wall]

Buy an inexpensive vacuum/pressure guage (I got one
for about $15). Tee it into the boost enrichment
duaphram line(Little hose from the intake manifold to
injection pump. Place the guage where you can close
the hood w/ out pinching the hose and where you can
see the guage. Go for a drive. Load the engine by
going up a hill at full throttle. Run the engine out
to about 3000 RPMS. At about 2,000 RPMs boost begins
to build. You should get a reading of 9 - 10 PSI at
about 2,500 - 2,800 RPMs under full load. Some turbos
are audible, some are whisper quite.
