Are you losing boost?

[Petrina Polo]

I think this should be done periodically on all turbo cars..

Trace all connections from intake to turbo, hot side pipes to intercooler, post intercooler pipes to throttle body.. Inspect for leaks and tighten clamps etc. Tighten DV as well.

I have a forge FMIC, With added boost courtesy of APR tune. The cars are more likely to shake the clamps up a little, loosen them up, maybe leak boost. My old XR6T used to loosen up the clamps all the time. My boost gauge was holding boost over 22psi so I doubt it was leaking much or at all. But it was a little jagged at times..

This is a pain in the bum job, thankless job.. You may or may not improve your cars performance, dependant upon if your clamps are tight and if there are any slight boost leaks. The front bar needs to be removed on our Polo Gti.

I grabbed a bottle of thread locker (mid strength) and lubed up the clamps and reset them nice n tight. Prevent me having to do this again in the short term.

With the forge FMIC setup, I noted the following issues...

1. Clamps were loose especially off the turbo hot side.
2. The front fog light had pierced a small part of the silicone hose (intercooler to throttle body). I shielded it to prevent further damage to the hose. There was no hole but it was wearing away.
3. The screw holding the aluminium pipe in place had broken off and the mounting part of the aluminium pipe almost worn away. Suggests to me there is a fair bit of movement of this setup whilst driving. The aluminium pipe was not fixed properly due to the screw braking off.. A bit of wire and now its properly fixed.

This is a good opportunity to clean up the intercooler as well. Now its nice n shiny..

Ill see if the car goes better tomorrow. I hope its not 2 hours wasted time.
