all i seem to get is 0.4 boost all the time standard set up should be more then that right?
Is that Bar?
Standard twin set up should boost to 10 then dip to 7 for the change over for the second turbo then boost again to 10psi matey.
yep thats bar it does not dip just goes up to 0.4 bar then stays there :/ allways been like that so i dont know if its right or not
just to add i can hear the first turbo very clearly upto 5000rpm after that cant hear the turbo noise so much any more is that normal
Just looked and 10psi is around 0.7 bar. So it looks to me that its not boosting properly and your second turbo isnt spooling up. You should feel the dip/change over when driving.
i can feel a change at around 5000rpm but its nothing to shout about only really feel it in second gear thanks for the help gandy :Thumbs-up
you`ve got a boost leak buddy :) o the joy lol... you should be se`ing 0.7 bar of boosty, 0.74 i think.. off comess the plenum time...
check all the easy to see pipes first, but most likely it`ll be under the plenum thats leaking..
cheers :)
so im looking for a ****ty vacuum hose then hmm thats gonna be fun
Coincidentally I have exactly the same problem but only boosting to 0.3 bar. Booked in for a fix as it needs mapping before my MOT really :)
this could get intresting as i have only ever know the car to be like this im guessing it might be a tad quicker then what im use to lol
have a look at the y-pipe coupling, mine have this prob and it was the pipe there (had an almight split). Can you hear a hissing? Also try replacing you pressure chamber, this can cause all sorts of boost probs, i picked up a spare for £5
come over ill sort it out mate, seemed to have sorted everyone elses around here lol :rollin
Are you geting your pressure reading from a boost gauge, if so then check your gauge 1st.
Also check your intercooler piping as i had an anoying boost leak and spent 2 days looking at every vac hose imaginable, turned out to be one of my silicone intercooler couplings, the clamp had sliped a little at the bottom where i could not see it and was leaking so i was running on .3bar
ok john came over and we pulled the plenum off no sign of any problems under there also replaced the pressure chamber tried two different gauges both do the same thing go to 0.4 the needle shakes around alot and it does dip when the second turbo tries to come on but it dips to 0.3 oh and there is alot of oil in the primary turbo intake :/ not sounding to great is it:rollin
might take you up on that but you dont know what your getting yourself into lol
Quote from: m4drxcome over ill sort it out mate, seemed to have sorted everyone elses around here lol :rollin
opps forgot to add i now have a whistling noise coming out the air filter on tick over what with that and the mooing from the air pump my car now sounds like its got a farm under the bonnet:rollin
non-sequential !!!!
Hey Jit, know your pain! I had a bugger of a time with mine, there are a LOT of things that can cause low boosting, have you had a look at the vac pipes to the LEFT of the UIM (you will need to take the plastic intake hoses off to see them) in the end my problems were caused by these pups being rather brittel and split.i could keep going and going with causes as i reserched it pretty indepth
Not sure what you got unde the engine, but have you checked that the pripes to the IC and TB are on tight? as they can leak through here (maybe thats your whistle)
thought i might add that the exhaust fumes smell a little and if you stand behind the car the fumes burn your eyes lol dunno if thats normal either :/ its like tear gas baby yeah hahaha
Yeah it usualy is hot and runs rich :Tongue1 Stick with it Jimjitsu you\'ll get to the end (good looking car too and best color) and will have beated one of the most complex systems on the car :wiggle ooooorrr go non-seqif you cant beat/fancy the delivery of.
You say you have a whistle up to 5k I had a similar problem thinking about it (car woulld whistle all the way to around 4.5k then go quiet when the 2nd turbo kicked in) And it was because i in my finate wisdom messed up with the Elbow, having it slightly off. (was resting on the gasket, reseated it and no more whistle.) Not saying this is your problem but it sounds similar,As people have said, check those IC pipes from the Turbo to the Thottle body. takes 30 mins just make sure they are all secure and good:yes
Also dont think ive seen the engine of your car m8 do you have a pic? ^^
give me a call in the evening mate and ill let you know what to check.
fixed ALOT of boosting issues for myself and friends members etc as you may have seen from peoples posts so have a degree of experience that i can apply.
all the best mate.
tharek
ok tried out the fault code thingy and it flashes one ober long flash then just keeps flashing quickly 5 times over and over again what does this mean? tharek i dont have your number buddy drop me a pm ;)
Hey Jimitsu, have a look at : http://www.mazdarotaryclub.com/forums/showthread.php?t=23569 it has a link to the FD error codes, they loop in sequence.
