brettjones Posted September 9, 2007 Share Posted September 9, 2007 how do you check if the 2 nd turbo is working i only get 13 psi i am running a full decat with no r/ring cold plugs bigger fuel pump and a boost gauge supramatt has been great he has done most of the work but we have hit a wall with this we spent 3 hours stripping the bits off last night and it looks like the 2nd turbo is not working there is no oil marks any were and intercooler pipes are all very clean Link to comment Share on other sites More sharing options...
Chris and Alana Posted September 9, 2007 Share Posted September 9, 2007 I dont think you would make 13psi on the first turbo and if you did it wouldnt last long. Try a manual boost controller (£15 or so) and try and increase the boost of tubbie 2. Link to comment Share on other sites More sharing options...
brettjones Posted September 9, 2007 Author Share Posted September 9, 2007 we have found the problem its a valve on the top which is not closeing supramatt has come good again Link to comment Share on other sites More sharing options...
jaymdee Posted September 9, 2007 Share Posted September 9, 2007 which valve mate? Could be the Intake Air Control Valve not opening, so no air passing into T2. Be interested to know Link to comment Share on other sites More sharing options...
