What Happens when you run too much boost?

[Ian]

You end up splitting your Turbo pipe.

£55 to replace, D'OH !

you are lucky that the pipe split before other stuff happened!!!!!!!!!!!!!

 

[Ian]

Why, what else could of gone?

Depending on how much too much boost is you could knacker pretty much anything in the engine/drive train. By upping the boost (or any other modification) you have the knock on effect of adding extra strain to things like pistons, gearboxes, driveshafts, rods etc.

Oh I realise that.

Most of these diesels nowadays are pretty resilient in terms of engine, and yes you're right it's usually drivetrain that goes.

I can damage the Turbocharger if I keep it under high boost with this broken pipe - well, it's not a major break, but it is losing boost.
