Can you please comment on the scan?

[sinannasirli]

Dear All, I made my first scan.. please find results attached. Can someone please comment if there is anything unusual?

Especially my main problem I do not have boost. The maximum boost I caould achieve is .25 bar.

I did a wastegate wiggle but it did not help(maybe should have spent more time). The car is 35.000 miles. CAt is cancelled and tht exhaust pipe looks like quite narrow (41 mm), if any of above makes any difference...

Thank you ın advance!!

Boost/rpm for my car

Would that mean a leak etc? What shall i look for? Thanks

Hi.. Still waiting if anyone can...

Well, I think your idling manifold pressure is a bit high.
As far as I know, it should be around 0.30-0.31 bar. Yours seems to be more around 0.35-0.36 bar, so there might be a little leak to fix.
I don't know whether that could explain such a low boost, though.

PS: I think you should ask someone to move your post in the "Turbos, Boost, and Intakes" part of the forum (viewforum.php?f=31)

Definitely looks like a leak. Remove the corrugated pipe from the air filter and blow into it to see if it will hold pressure. You may be able to hear a leak - favourite places are the small connections at the manifold and the vacuum reservoir tucked under the wheel arch liner. Then go and look in the mirror and admire your new goatie beard.

Thank you for the advice..

I was waiting to reply until I do this, but still could not find time to do due to travels.. As soon as I do this will share the results

I was going trough some posts and noticed that I never closed this thread and shared the end results..
The PO had put a smaller diameter exhaust piping ( cheap repair) that was the issue.. The poor engine could not breathe, that was why there was no boost..

So if anyone there, please check exhaust piping first..

Also sorry that I have never shared picture of my goatie beard..
