addi Posted February 16, 2005 Share Posted February 16, 2005 may be a similar post to the 'wierd boosting' post but i suspect my car to have blown the second turbo as while boosting i am getting nothing from it when it should come on line .. car boosts to 1.2 bar as usual .. then when second should come in boost falls to 0.5 tried the TTC, when the turbo comes in the car boosts to 0.5 and stays there it is also coupled with white smoke from the exhaust when ticking over for a while and oil appearing to be coming out from the dumpvalve any ideas before i start removing and swapping turbo's ?????

tbourner Posted February 16, 2005 Share Posted February 16, 2005 I thought white smoke was coolant? I think you'd know if it was HGF though. Link to comment Share on other sites More sharing options...
The Hornet Posted February 16, 2005 Share Posted February 16, 2005 I presume you have checked all the hoses etc... Do you get a whining noise when the 2nd T should be coming on? Link to comment Share on other sites More sharing options...
Kopite Posted February 16, 2005 Share Posted February 16, 2005 any of the dreaded death whine coming on at all? Link to comment Share on other sites More sharing options...
addi Posted February 16, 2005 Author Share Posted February 16, 2005 yeh a whine wen the second turbo should be on and it only gets to 0.5 bar at the most Link to comment Share on other sites More sharing options...
Jake Posted February 16, 2005 Share Posted February 16, 2005 Have you recently decatted or done any other mods? Link to comment Share on other sites More sharing options...
garetheves Posted February 16, 2005 Share Posted February 16, 2005 I may be completely off the track with this because im a newbie when it comes to engines, so correct me if im wrong, but i was under the impression that the first turbo boosts to 0.7 approx then the second only comes in at 1.2bar, so if yours is boosting ok to 1.2 then surely its not a 2nd turbo prob. May be a prob mainting the boost but not acheiving it. Prob way off but hey. Gaz Link to comment Share on other sites More sharing options...

Gaz i think the second turbo comes on on a a none dectated car at just under a bar which if memory serves is roughly 14/15 psi. Could be wrong tough Link to comment Share on other sites More sharing options...
addi Posted February 17, 2005 Author Share Posted February 17, 2005 the car is fully decatted with a 1.2 bar restrictor ring Link to comment Share on other sites More sharing options...
Steve W2 Posted February 17, 2005 Share Posted February 17, 2005 Could be an oil seal if you are getting smoke. However, the whining noise definetly isn't good. Are you sure its not the whistle the standard turbo's make anyway? Did you get the decat done, or was it done by the previous owner. If you have properly blown your turbo it's pretty unlikely you would generate 1.2 Bar boost. Link to comment Share on other sites More sharing options...
Ian C Posted February 17, 2005 Share Posted February 17, 2005 Um, 1.2bar on the first turbo? That's so unbelievably far out of it's operating range (power drops off above 0.9bar due to overheating the air) I'm amazed it's not #1 that's dead if this is correct You could have a faulty part of the sequential system dumping boosted air to atmosphere as soon as it tries to bring #2 online?

addi Posted February 17, 2005 Author Share Posted February 17, 2005 no ive had the car for 2 years no wand bought it standard its just had a full rebuild at grasshopper prosport, now as its run it ive gone to start to accellerate and found nothing coming from no.2, the car runs great otherwise, been told be gps that teh second turbo is gone and generating nothing, just dont want my pants takin down for a poped off hose or similar .. and it is getting to 1.2 for a split second then dropping streight off to .5 .... it is running a greddy profect controler aswell Link to comment Share on other sites More sharing options...
Ian C Posted February 17, 2005 Share Posted February 17, 2005 If it was fine before it went for a full rebuild and now #2 doesn't work I'd say the problem lies at Grasshopper... You need to check all your sequential system hoses, especially the stuff that brings #2 online. Could be they didn't put them back right/properly or they got split taking them off, or even a VSV hasn't been plugged back in... -Ian Link to comment Share on other sites More sharing options...
addi Posted February 18, 2005 Author Share Posted February 18, 2005 hmm .. it went into grasshopper due to a blown engine (2 cracked pistons) turbo's was runnin ok before Link to comment Share on other sites More sharing options...
Ian C Posted February 18, 2005 Share Posted February 18, 2005 How did it wreck two pistons? Which pistons were they, as debris may have entered the turbos and damaged them... -Ian Link to comment Share on other sites More sharing options...
addi Posted February 18, 2005 Author Share Posted February 18, 2005 det and a poor fuel pump resulting in very lean mix plus det = two crscked pistons that are now an orniment on my desktop lol Link to comment Share on other sites More sharing options...

tbourner Posted March 1, 2005 Share Posted March 1, 2005 Like I said before isn't white smoke an indication of coolant burning? Just trying to look at different avenues before changing tubbies. Link to comment Share on other sites More sharing options...
