RICHARDA Posted March 21, 2005 Share Posted March 21, 2005 Hi Chaps Please can you help diagnose this prob, it sounds to me as if my Turbo no.2 may be on its way out, however the symptoms are: Only boosts to 0.5/6 bar at WOT After kickdown and as no.2 comes into play it, spluttered/coughed and let out a small cloud of black smoke, revs seemed to rise but lack of power. Turbo no.1 seems OK UK spec auto with full de-cat and blitz Nur spec (85k miles) Once I saw the smoke I drove slowly home, no smoke on way back but I did'nt use no.2 I would be grateful of any feedback. Many thanks Rich Link to comment Share on other sites More sharing options...
Dragonball Posted March 21, 2005 Share Posted March 21, 2005 Bung it into true twin mode Rich and see what it does - you will see full boost if ok But sounds ominous If you want to get it checked out at the workshop - let either of us know Link to comment Share on other sites More sharing options...
Bobbeh Posted March 21, 2005 Share Posted March 21, 2005 Pipe come off ? Black smoke = overfueling right? So if its not getting the air in its not burning properly?! Are you getting the death wine that's synonymous with turbo failure? Link to comment Share on other sites More sharing options...
RICHARDA Posted March 21, 2005 Author Share Posted March 21, 2005 Great replies! Thanks Paul for advice, I may well drop in to see Paul. Bobbeh - no death wine, have checked pipes, but theres so damn many, I must admit I have fitted a nice shiny I/C pipe set, the one from the throttle body and one that goes to the turbo pipework, so may have disturbed/knocked something but I have checked for anything obvious, I think that is just coincidence? Any more ideas? Thanks again Rich Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 22, 2005 Share Posted March 22, 2005 Sounds like an IC pipe off or partly off to me. Link to comment Share on other sites More sharing options...
Soonto_HAS_soop Posted March 22, 2005 Share Posted March 22, 2005 I was just about to say the same as Chris. When I had my EGT fitted, the guy forgot to tighten one of the rubber joints on my hardpipes when refitting, at a certain RPM it used to cough and splutter. Found the joint, tightened it, and no problems. It used to show some boost, but not full power, as when 2nd came in, air escaped out of the joint.

RICHARDA Posted March 23, 2005 Author Share Posted March 23, 2005 Right, I have checked all the pipes and all seem OK the only thing I found is that one of jubliee clips around the hose from the throttle body was ever so slighty loose, I don't suppose this could be it? (Hose is perfectly in place). Any other ideas? I really don't want the expense of buying new turbos! Ta Rich Link to comment Share on other sites More sharing options...
Dragonball Posted March 23, 2005 Share Posted March 23, 2005 Bung it into true twin mode and check what it does Then bring it on up to the unit over the weekend to have paul look at it and confirm either way m8 ? Link to comment Share on other sites More sharing options...
