Good Evening all...
My turbo isn't achieving full boost for some reason and I'm getting more black smoke that normal. I have a boost gauge fitted and I normally get around 9.5psi but now I'm only getting 6-7psi at best. All pipes are fine as is the waste gate which moves freely with the actuator rod removed. I have shortened the actuator rod by a considerable amount just to see if it would make any difference, which it did only slightly. If I was to shorten the rod as far as the thread would allow it might just scrape 9psi but there is something obviously wrong for me to have to do that. There is very little oil in the impeller housing, the fins are fine as is the bearing. Any suggestions welcome.
