Hello, just a quick question about these here turbos.
I've recently bought a Mk1 leon FR TDi with 80k on the clock. It has FSH and runs like a dream but I'm wondering....how long can you generally expect a turbo to last if the car has been serviced correctly? 100k? less? more?
Many thanks
I think what kills turbos the quickest is asking for lots of boost at low rpms. The turbos try to push too much air into not enough space, and this puts extreme stress on the turbo vanes. Ease into it until you get above 2000 rpm (2500 if climbing a steep grade), then your turbo should last a good long time.
EDIT: Actually, another question right now - why/how is it less damaging for the turbo to ask it for more boost at higher rpm? I assume it's because the engine is turning over more quickly, so the pressure generated by the turbo goes straight into the engine rather than causing back pressure?
Partly the reason for me getting my backbox chooped out was to reduce the EGT's, I have no actual proof/data to back this up but surely if the hot gases can escape quicker with less back-pressure then the turbo should have a longer/easier life.
