Tdi feelin the heat
mud-club-matty:
think it will get damaged then
Range Rover Blues:
I've seen pictures like this before on development engines, it's not uncommon for them to glow but a bit of air circulation works wonders you know.
Porny:
That's not hot....
You want to see the manifolds and the exhaust on an engine on the test beds at work when we do full load work...
They get that hot you can virtually see through them!!!
On a petrol you just dump more fuel down the exhaust (i.e. run it rich) and/or adjust the ignition timing....
But on a diesel it's the other way around... more fuel = higher temps (thus EGT)
Anything above 800 degrees on a Tdi or Td5 and you start getting towards the material limits for the cast manifold (hence why you get warped manifolds on badly tuned diesels)... much more than this and you will also find the fins on the exhaust side of the turbo will start to break up, and in extreme cases so will the exhaust valves!!
In saying that, in the short term, and for short blasts you will get away with higher temps.... I've known 300Tdi's that peak at 1200 degrees!!
