Point made! :homer:
What about any welds on your pipeing? Are they all ok? (Will be hard to see, but worth a shot)
yeah ive even checked them too......! Ive wrapped up a couple of the samcos very tight with electrical tape to make even doubly sure there isnt a leak..... and poured water down the pipes to see if any escapes.... im going deep with is init lol!
ok here goes, im going to freeze again! bloody weather!, better yet, BLOODY CAR!!

Boost preasure woulld try and expand the pipes, and therefor open the split.
If anyone can tell me how a turbo wouldnt work, if the fins are all ok and it spins free then ill look into that, but i cant see how it can be that.
Are all gaskets ok on the inlet mani etc?

Right...
Ive put everything back together on the car and took it for a spin **without a bumper** lol, looked sooo cool! Anyyyyway...
The problem is there...... car still feels quick and responsive.. no missfire and engine sounds normal....!!? JUST NO BOOST AT ALL!! the back pressure on the boost gauge flys up but doesn't go over 0.0BAR!! this is so annoying....' the turbo makes a really loud noise where its supposed to be kicking in but 0 pressure
Rory i havent actually taken the manifold off. I did suspect a leak from the mani as that would loose pressure, theoretically resulting less pressure to hit the propeller shaft and lack off boost... But then i would still get boost pressure of some sort unless the the hole was as big as my hand......! which isnt the case....
Can the only other thing be the turbo? however much some of you are doubting? whats the next step...? take it to my trust worthy local mechanic? although he doesnt tend to like problems like these......

@gtti......... sorry mate thats what im meant.... goes from vacume to 0.0Bar..... and the turbo is making a loud wailing noise... doesnt sound normal, but isnt horrid.. just wales like you said......
And sorry when i mean fast i mean like say say a nippy N/A car like a saxo VTR or something.... what im trying to say is it doesnt feel broken or anything.. drives fine still with good response but obviously no proper power by no means as the turbo is doing feck all..... engine feels fine when driving it.... but with say 1/4 of the power.....

Just adding my 2p and past experience, only time i've not been able to go above 0.0bar of boost was when actuator arm came off and the wailing noise, last time it was an intercooler pipe that had popped off.
hope you find a solution to your problem soon mate, get the beast back on the road.

cheers stu...
unfortunately my actuator arm is still in place and ive checked all pipes for leaks etc...
