Loss of Boost/Power - Mike - 02-07-2014
Hi All,
Recently i noticed my car wasn't boosting as it should and doesn't feel as quick
its got a 9mm bosch, no gov/ground lda + TD04 turbo.. It used to boost just over 2bar
But recently its only been able to get to 1.4/5 bar
Inbetween this i have messed around with the fuel pump but no matter what i do, i cant seem to get it over 1.5bar.. im sure ive made a total mess of the pump now.. so im gona put it back to as standard as possible tonight and start again..
But im just wondering if any of use know any other problems what could cause this?
Ive checked for boost leaks and im 100% sure there isn't any..
so other than the pump just being setup totally wrong.. i cant think of anything else what could be wrong.. unless the turbos slowly dieing?
Thanks in advance for all the help
Mike

Worth a mention the turbo has a welded wastegate

Have you checked for boost leaks? Are you sure your wastegate is still welded/sealed? Whats going on smoke wise out the zorst on full chat?
RE: Loss of Boost/Power - Dave - 03-07-2014
Is it smoking out the back compared to when it was boosting 2 bar? If yes, you have a boost leak/manifold leak. If no smoke then you have a pump issue

Well come on where was it?
RE: Loss of Boost/Power - toseland - 04-07-2014
the pressure hose had fallen off the turbo =D
RE: Loss of Boost/Power - Mike - 04-07-2014
The end of a mikalor clamp had worn away the rubber pipe what was under it lol.. But i just fitted a new one and its still not boosting correct -.- so it ain't fixed haha
Also to the post above about the wastegate.. That's definitely still closed.. And to the smoking question.. It smokes like mad on boost, gets to 1.4bar and i look behind me and its just black lol...
RE: Loss of Boost/Power - Tom - 04-07-2014
Coaling is either to much fuel or not enough air, so id say its still leaking somewhere.... Unless whilst playing with the fuel your now running more fuel than you were? But actually with a welded gate it should just keep boosting
RE: Loss of Boost/Power - Mike - 04-07-2014
Yea that's what i thought mate.. There much be another leak somewhere ): but cant do anything at the minute as its pooring down here
