outatime Posted May 12, 2004 Share Posted May 12, 2004 Seems to be a few boost q's this morning Since i've had mine ETTC'd, I only hit around 1.0bar max when running in sequential. The first turbo doesn't kick in until around 3k, the second just before 5k. In parallel mode, boost will go as high as 1.4 (EGTs were 810). Obviously, this is not good for my car so i'm keeping it in sequential for the moment I'm not sure if this is relevent, but i get a loud (actuator) rattle when running in sequential. It goes when I boot it in parallel, only appearing again after a drive in seq? Any ideas? Quote Link to comment Share on other sites More sharing options...
outatime Posted May 14, 2004 Author Share Posted May 14, 2004 No one got any ideas Its going on the dynos on June 5th, so i'd like to sort it out by then - should have some odd results otherwise. I'm replacing the speedo convertor, on Chris Wilsons recommendation, in an attempt to get no. 1 online sooner. Quote Link to comment Share on other sites More sharing options...

outatime Posted May 14, 2004 Author Share Posted May 14, 2004 1.3-1.4 bar, so I got a restrictor ring and it was around 1.2 after that. Quote Link to comment Share on other sites More sharing options...
outatime Posted May 14, 2004 Author Share Posted May 14, 2004 Forgot to say that its not holding boost for very long in parellel, it peaks at about 5k rpm then drops off through the rest of the range? Boost is fine in sequential, could it be something to do with the pressure tank? Quote Link to comment Share on other sites More sharing options...
