Turbo Boost Pressure
Posted by Gerald Reeves [Email] (more from Gerald Reeves) on Fri, 2 May 2003 15:24:28
I've been experiencing a reduction in the 'sustainable' boost pressure for my 9000 2.3T (1991 model). If the accelerator is 'floored' then the boost pressure raises quickly, as normal, to well into the 'red' zone of the APC gauge. However I'm finding now that the pressure is very quickly cut, or vented, so that the boost pressure falls to the top of the 'orange' zone on the gauge. I don't feel the problem is a weakening waste gate value as the problem has suddenly appeared - not sure though.
Any thoughts on how I can track the problem down or check components out? eg. what else 'cuts' the boost pressure ? Thanks....
