tony tt Posted November 5, 2012 Share Posted November 5, 2012 You havent made a mistake mate my tt auto pulls like a train when tubby two kicks in a 4000rpm. Superchip?? it's a boost problem for sure i've never seen a bleed valve like that on a supra. Is there a boost gauge in the car? Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted November 5, 2012 Share Posted November 5, 2012 If it is just a stock TT, you will find it a bit sluggish. The Supra only really comes alive if you carry out a BPU or go single. Do you have any idea on the boost you are getting? What are the Superchip's function? Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 5, 2012 Share Posted November 5, 2012 (edited) BPU auto supras fly along quite nicely, well i know mine does but then its de catted with full exhaust system ebc fcd, new intercooler, grade 7 plugs. I didn't think you could chip a mkiv so no idea what the superchip is. Is you car not de catted, have an fcd and restrictor ring fitted ? if not it wont be anything like a 400 hp bpu car. Get an electric boost controller, fcd, 1 bar restrictor ring, double de cat, grade 7 plugs and set to 1.2 bar and you'll see a huge difference Edited November 5, 2012 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Slicknick Posted November 5, 2012 Share Posted November 5, 2012 Sounds exactly like your 2nd turbo isn't coming in, I hope its just a vacuum problem and not the turbo. The Autobox is very good, mine certainly isn't sluggish. Quote Link to comment Share on other sites More sharing options...

safcdixon Posted November 5, 2012 Share Posted November 5, 2012 I would remove that bleed valve as a start point checking all hoses for splits in the area around the turbos and inlet , as already said my bpu auto goes very very quickly have you checked the simple things like plugs, coil pack clips etc Quote Link to comment Share on other sites More sharing options...
Lee P Posted November 5, 2012 Share Posted November 5, 2012 As already said, sounds like one of the valves are not working correctly and not letting the second turbo work properly. I would avoid driving hard as you may do some damage. Does it feel like its surging a bit after 4000rpm? What does to boost to? Quote Link to comment Share on other sites More sharing options...
Geo Posted November 5, 2012 Share Posted November 5, 2012 Sounds Defo like your either still stock boost. And it your 2nd turbo ain't coming online at 4k I've been in tonytt's auto and it goes like the clappers. So much so I get butterfly's in my stomach when he nails it.

SPG Posted November 5, 2012 Share Posted November 5, 2012 Hey Patrick, pull up the carpet in the passenger side footwell and see if its a standard ECU you are running firstly, secondly the valve looks rather odd and if it is supposed to be a manual boost controller then i would remove this. At 4000rpm your man-dangle should be tingling (assuming you are male/or not post sex-Op) Quote Link to comment Share on other sites More sharing options...
Guest fripon Posted November 5, 2012 Share Posted November 5, 2012 it's got standard cats and exhaust.yes i was expecting the car to really pull well after 4000 rpm as it's great under.superchip was on the car already.am going to ring the previous owner.the car was not being used a lot.what to do now:( Quote Link to comment Share on other sites More sharing options...

tony tt Posted November 5, 2012 Share Posted November 5, 2012 Paul whiffin!!heard of him Whifbitz garage is in Enfield and knows the supra very well. He is pricey though but your best bet if you are stuck. Quote Link to comment Share on other sites More sharing options...
Guigsy Posted November 5, 2012 Share Posted November 5, 2012 As leep said (and you shouldnt ignore what he says, he knows his stuff!) it definitely sounds like the boost/exhaust valve things (vsv's). Especially If it wasn't used much. Mine has done it a few times and after a few hard pulls normaly frees up. But yours may be totally stuck. Take it to whifbitz or austec. They are traders on here and probably local enough to you. Quote Link to comment Share on other sites More sharing options...
Guest fripon Posted November 5, 2012 Share Posted November 5, 2012 just spoke to the previous owner.he said he never took the car above 4000 rpm.he bought because he likes the look and only used it around town.he has got no idea. Quote Link to comment Share on other sites More sharing options...

T2 MSW Posted November 5, 2012 Share Posted November 5, 2012 Did you not test drive the car before you bought it? I would not have bought the car until I knew more about it and had fully tested that everything works as expected. Ie a test drive with a few over 4k pulls.
