jevansio Posted December 5, 2007 Share Posted December 5, 2007 Well I went down to Motoscope with my 0.81 housing all excited, half an hour in and we were ready to prise the old hosuing off, when it came off I couldn't believe it. The turbine blades had disintigrated around the edges, Richard said it was typical of high temps. Well those 1000+ temps I was running before may well have not melted a piston, but they sure have fecked my turbo. Will get pics tonight. Luckily I phoned Michel & he has a 0.81 A/R GT4088R with a polished compressor housing , went up to get it from him & MS are fitting it now. Hopefully this new good turbo will unleash the power I've been craving top end. Ryan is mapping the car this weekend so fingers crossed Saturday afternoon I'll be happy.

Nic Posted December 5, 2007 Share Posted December 5, 2007 2step/Antilag... Jamie had the same problems with his I seem to remember. Quote Link to comment Share on other sites More sharing options...
jevansio Posted December 5, 2007 Author Share Posted December 5, 2007 I have used the 2 step a bit, but I thought DBB's could handle it. I've used maybe 20 times. Is the 1000+ EGT's not a more probable answer? Quote Link to comment Share on other sites More sharing options...
suprafan72 Posted December 5, 2007 Share Posted December 5, 2007 Ryan G had this problem as well and i don't believe he had 2 step antilag or high egt problems... Bad Design?? The EGT's wouldn't help though... Quote Link to comment Share on other sites More sharing options...
Nic Posted December 5, 2007 Share Posted December 5, 2007 Ryan G had this problem as well and i don't believe he had 2 step antilag or high egt problems... Bad Design?? The EGT's wouldn't help though... I thought Ryan's was due to the crap welding from the XS Power manifold going through his turbo? Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted December 5, 2007 Share Posted December 5, 2007 Hello From Scotland Just waiting for plane Home Anyway mine went due to welds falling apart from crap xspower manifold But would bet big money yours is down to the 1000+ egt's This is why Antilag and 2step can kill turbos as the egts created to make the exhaust energy for spinning up the turbo quicker will just kill the exhaust turbine Will chat up with thread later when i get back to oxford Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 5, 2007 Share Posted December 5, 2007 And as for "DBB's handling it", the DBB part is the core bearing technology, the rest of the turbo is exactly the same. So let us nail that particular myth here shall we -Ian Quote Link to comment Share on other sites More sharing options...
dandan Posted December 5, 2007 Share Posted December 5, 2007 And as for "DBB's handling it", the DBB part is the core bearing technology, the rest of the turbo is exactly the same. So let us nail that particular myth here shall we -Ian I was working my way down through the posts and was going to post exactly this - beat me to it! Who the hell suggested a DBB turbo could outlast a journal/SBB turbo under antilag and 2 step conditions?? Quote Link to comment Share on other sites More sharing options...
jevansio Posted December 5, 2007 Author Share Posted December 5, 2007 I can't remember where I heard it, when I was at Motoscope examining the this the exact same thought crossed my mind, it's getting disabled on Saturday when I see Ryan Quote Link to comment Share on other sites More sharing options...

jevansio Posted December 5, 2007 Author Share Posted December 5, 2007 Exactly the same, so is mine caused by EGTs, 2 Step or something going through? Can you tell that from the pictures? Manifold is Sound Performance. Quote Link to comment Share on other sites More sharing options...

jevansio Posted December 5, 2007 Author Share Posted December 5, 2007 Too big, not really interested in monster top end, want it to be a bit lievly low down Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted December 5, 2007 Share Posted December 5, 2007 Blimey Jay was not exspecting yours to look like mine. Looks like something has Been through yours aswell. Mind you I came into a problem with a phr kit a month ago when the wastegate jammed open. A Nice piece of weld popped out when I pumped the valve open to un jam. Had to look again to make sure it was not a xsflower one Ryan Quote Link to comment Share on other sites More sharing options...

Ric Posted December 5, 2007 Share Posted December 5, 2007 Have a look up of jamiep's thread if the pics are still there, they look similer, and AFAIK his was just down to 2step/antilag it was found Quote Link to comment Share on other sites More sharing options...
Alex Posted December 5, 2007 Share Posted December 5, 2007 Just going by the fact that they seem fail a lot yes, IMO though. It's not a 4088 from eBay.... The that has failed a few times is the GT4088, usually in Truck spec. The GT4088R Jevansio has is a completely different kettle of fish, it's a proper road car/petrol turbo. I'll lay money on that turbo being totally fine when treated properly...Anti-lag is ONLY for rally cars and race cars who change their turbos every other run.

Homer Posted December 5, 2007 Share Posted December 5, 2007 Just to add to Alex's post, Jamie and Ryan had the 4088, Jay has a 4088R, completely different turbos. Quote Link to comment Share on other sites More sharing options...
