Blown Turbo

Copper Slip is not only for brake pads but is ideal for coating on bolt threads to lubricate them and prevent corrosion. Particularly useful where there's heat i.e. the turbo and exhaust bolts which will undo again much easier. Also good on wheel bolts/nuts.

and suitable for VERY high temperatures

Nice one lads, I bet we'll all keep our fingers crossed for you that the turbo is still ok.

Copper slip is up there with super glue and WD40, they are just all great things that have been invented !!!!!!!

Well took the car out today and it is only producing about 6-7 psi, this is with the air lines to the wastegate disconnected, so in theory it should overboost :?

Slight improvement. What should the boost pressure be?

Are you sure you have all the exhaust cement out of the system? Nothing trapped under the wastegate?

With all the messing around trying to solve the problem not sure where the boost is set which is why i was running it disconnected from the wastegate ro try and it to overboost..

I have have since found that the new air pipe from the new filter has been slightly squashed reducing the overall diameter so wondering if this could be a factor.

We hoovered out the exhaust to try and make sure that all exhaust paste was out.

I doubt the Hoover has as much suck as the exhaust has blow iyswim?

Maybe the squashed inlet pipe is causing the problem. It's not collapsing because the filter isn't big enough can't pass enough air is it? Just a thought.

Early Samco inlet pipes had a collapse problem on Imprezas, so I belive.

we've checked the turbo, intercooler and pipes no leaks or blockages so will have to check to see if any intake pipes are collapsing or blocked :roll:

hi did you check the wastegate if is staying open or Blow Off Valves staying open :thumb:

Already checked as when we fitted it it was blowing through the wastegate.
