back on the road half a week and this happens [img]images/smilies/mad.gif[/img], not sure it's the DP but i can't boost past 7 psi, i've done an ECU reset but no change, also, i can't alter the boost with the Dawes either


kev

 

Split hose????

Just an idea

 

was thinking that, must have a better look, even take all the pipes off and start again

was hoping it was going to be something a bit easier to find


kev

 

Maybe take the i/c off and check they are all secure underneath??

 

just took all the turbo to inlet manifold pipes off and inspected them and put them back, will check again tomorrow (neighbours won't be impressed driving around at 11 o'clock at night )


kev

 

no different today [img]images/smilies/mad.gif[/img] it's not a leak

is this going to be anything to do with my Dawes? just flowed the heads and headers and fitted a decat DP all at the same time, i'm running the standard bleed hole size - could that be a problem now?


kev

 

Kev,

Its strange that 7-8 psi is about actuator pressure but if you have the dawes then you wont have the boost solenoid connected? If you did i would have checked for kinks etc. Personally, I would put everything back and remove the dawes, to eliminate, and then check all pipes again. Cant see how your mods would cause this.

Cheers

Paul.

 

that's what i was thinking, if i put the solednoid back into the system instead of the dawes then i should hit 11psi (standard)

job for tonite


kev

 

not had chance to test it yet will try and have a go tomorrow, although i put the original boost controller back on but it didn't seem any different, will have to borrow my brothers boost gauge as mine is broken [img]images/smilies/mad.gif[/img]


kev

 

7 psi, sounds like the ECU has put the car in limp home mode for some reason. It usually does this when a sensor is buggered. You may have a faulty MAF sensor, the usual culprit.

Cheers,

Wrexy.

 

can it alter the boost if the solenoid boost controller isn't plugged in so to speak, surely it can't control the Dawes


kev

 

wategate stuck open?

 

got round to putting the standard boost controller back on yesterday, now i'm getting too much boost [img]images/smilies/mad.gif[/img] keeps hitting fuel cut, any ideas how it's getting past the standard 11psi


kev

 

sticking wastgate was my cause a couple of years ago on my99.

 

Check the wastegate actuator and the wastegate "penny" (has it dropped off. If these are OK, chances are that you need to increase the size of the hole in your restrictor.

Duncan

 

will have a look at the actuator tomorrow (not much more it can be), not familiar with the 'penny' term though, explain


kev

 

8psi is the crack pressure of the wastegate - sounds like you have lost control of the actuator

Trout

 

well, solved the overboost, the pipe to the actuator had blown off (can't see how it's managed it) so when i can get the car out the drive i'll see what happens next


kev

 

dont have much luck with that car do you mate

hows the box going anyway, still ok?

ian
p.s. have you got any spare water feed/return pipes for the standard turbo??
even just the lower one would do, cheers.

 

same could be said for your luck gearbox is just fine, not got any turbo bits lying about i'm afraid


kev

 

still goes rounds corners pretty well


kev

 

all fixed put the dawes back on then had to do a bit of setting up to get it back to fuel cut though

can't say i know how it got fixed though not complaining


kev

 

nice one mate

 

see how long it takes for the next thing to break, saying that, the exhaust keeps falling off since i put the DP on, getting a new section delivered this week (thats if parcel force can do their job )


kev

 

the exhaust will probably go via russia before it gets to your door

if ur upping the power, watch that bloody g'box!

 

i know, dead careful about flooring it in first
