plzzzzzzzzzzzzzzzzzzzzz

 

Are you very sure all the 'vacuum' pipes are still there? Didn't the one connected to the nipple on the turbo fall off? Sounds like your wastegate never opens.

Whether that can cause the horrendous noise you're hearing, I don't know.

Also have a look at the gasket between downpipe and mid-section...I know of a case (on a MY00) where this was damaged - the noise the car made sounded ilke something from a horror movie.

Maybe the cat in the downpipe broke up...?

I won't drive it like that.

 

now removed heatsheld from turbo and up pipe and the rattle seems to have gone,

BUt there still seems to be more boost than before, the whistle we get when boost is on is alot louder than it was before????
also when off boost i think i can here a sucking sound coming from somewhere but cant tell were,

 

I have My00, ppp, itg, group A down pipe, and custom decat middle,

to day while driving to town, i heard a rattlw from the turbo area,
thought that it was just a heat sheild or something, so carried on and went to overtake, droped it down a gear and the car boosted like hell, it was so fast, and then it dyed of boost on it own,,,,?

as if there was a vacum pipe fell of or something,i have checked all the pipes and every thing looks ok,

but now i have this sort of rattle it seems to be underneath the car where the middle fits onto the down pipe area, but it is not blowing,

also the boost still seems alot higer than it should be but wont hold much, at a guess it seems like is boosting at about 17/18psi and holding at about 13/14psi, and the whistle we get from our turbo on boost is alot louder aswell,???????

the rattle noise is loudest when i take foot of throttle, and in the gearchanges, oh had some pinking as well,

and the fuel consumption has gone more terrible than terrible

PLEASE HELP,

thanks in advance Leon
