Duffman Posted September 26, 2008 Share Posted September 26, 2008 Was fitting my boost gauge earlier and wasnt too sure where to fit the t-piece.(even after many reads at the post on here) Anyway I took the hose from the turbo pressure sensor out the original Y and put the boost gauge hose here...didnt sound right at all...the engine was about to conk out. Put it back to the way it originally was and took it out a spin and it felt so much faster when on full boost...as if i'd maybe done something by removing the 'turbo pressure sensor' hose. Is there anyway that this could change what my boost is running at? Really don't wanna melt my engine Quote Link to comment Share on other sites More sharing options...
ivan Posted September 26, 2008 Share Posted September 26, 2008 Please, please, please put the hoses back the way they were originally and get someone to take a look. It won't cost the earth. Quote Link to comment Share on other sites More sharing options...

Yes exactly, please do... I had this recently which Ivan discovered; My boost gauge hose was directly connected to my FPR which as she is a vvti, is very sensitive and if she ever run lean, i wouldn't know about it... So i had it put back to the way it should be... Quote Link to comment Share on other sites More sharing options...

You can't change the level of boost you are producing by messing about in the area. However you can melt a piston quite easily. That sensor is the thing the ECU uses to determine how much fuel to inject - if you've introduced a boost leak in that area then it will see a lower pressure than you actually have, and it'll inject less fuel than it should. A leaner fuel mix gives, to a certain extent, more power. If this is why your car feels stronger then you need it fixing quickly otherwise you'll damage the engine - the leaner mix also causes much higher combustion chamber temperatures, rapidly leading to detonation and damaged pistons. -Ian Quote Link to comment Share on other sites More sharing options...

Is there anyone nearby who thinks they could help me out by taking a look...im near glasgow. Would really be appreciated Edited September 29, 2008 by Duffman (see edit history) Quote Link to comment Share on other sites More sharing options...
