Escaping boost??

[GeoffSmith]

I had the clip break on the pipe to the plenum and it hissed on high boost (before it gave way completely and it hissed all the time). Remove the turbo inlet pipe at the filter and blow... there should be no leaks but if there are you should be able to find out where they are.

















































Then go an look in the mirror!

this sounds exactly like the problem i have been experiencing. I've changed plugs, leads coils and CAS assembly with no difference. I'll check the turbo pipes today/tomorrow and if i find anything i will post the images

I have been feeling the same.Like scaping boost only in full throttle.I also changed a stainless steel exhaust a little bigger but only the last section of it, I did not think this could influence the turbo. This week I will visit my mechanic and we will try to fix it or find why it is...

I found my high presure leaks by removing the turbo inlet pipe and fitting a rubber bung into the turbo with a hole bored in it. Plugged an air line in it and blowed in air (engine not running of course). Not so much that the pipes blow off, but enough to see if there are any leaks, you'll hear where they are if you have any.

Hats off to you - this is one of those incredibly elegant solutions that causes one to ask "Why didn't I think of that?"
