SteveR Posted March 11, 2009 Share Posted March 11, 2009 Ifou are leaking bost (e.g. through a busted intercooler or poor connecting pipework) then ASUI your turbos will overspool as there isn't anything holding them back and the safety cutout (fel cut) is based on the pressure they achieve... and clearly are nowhere near that level. Avoid making boost until you get it fixed, or risk the tubos going pop. Quote Link to comment Share on other sites More sharing options...

j1mb0b1 Posted March 31, 2009 Author Share Posted March 31, 2009 (edited) Right update i have now fitted my new Gready FMIC and all pipe work correctly and there is no leaks on the new installation. But i am now only seeing around 0.6 / 6.5 bar of boost on second turbo should it not be in the 0.7 / 0.8 bar range ? and for some reason it will boost up to 8 bar when iam in 6th on first turbo but not in any other gear.. Could this be a fault on my boost guage as it also will bouce up and down some times when second turbo comes online, but the car does not seem to be jumping around as the boost on the guage is saying just a bit lost atm is this all normal or do i have a problem ? Thanks for any help !!.. Edited March 31, 2009 by j1mb0b1 (see edit history) Quote Link to comment Share on other sites More sharing options...
SteveR Posted March 31, 2009 Share Posted March 31, 2009 8 bar???? whatever is happening, it's not right. Are you sure there aren't any leaks or blockages in the boost gauge sensor's plumbing? At best it's a gauge-related issue, otherwise it could be your VSVs (or even your turbos ). Quote Link to comment Share on other sites More sharing options...
