I would suggest that if you do not currently a have a boost gauge and an exhaust gas temperature gauge, get them and fitted ASAP. A couple hundred dollars spent on those 2 gauges (and monitoring them) can save you thousands in engine repairs.

Hi all

Bearings in a turbo are a bit like an un balanced prop, you won't get peak speed boost.To much play and the veins wobble and touch the turbo housing and bang goes the turbo only saying.

Anyone second that or am I alone on this.

That is definitely true, but my point about the importance of the boost and EGT gauges, is to keep the engine. It is very easy to destroy a boosted engine if the exhaust gas temperature is excessive, and the only way of knowing if the EGTs are within safe limits is if they are monitored.

Have a look on the Ford Mermaid Turbo Thread, I put up a couple of suggestions there. The black smoke can be a symptom of the problem I described. Black smoke can also mean blown turbo. Too much fuel not enough air!
