  Just curious if that's an absolute or relative pressure gauge?  Some of 
the Audi's had one, some had the other.  My uncle was always talking about 
the high boost they ran the bomber on, for takeoff, but he finally admitted it 
was probably absolute pressure.  Still impressive but not quite the "how'd 
you keep the head on the cylinder???" kind of pressure!
