--- Quote from: "V8_redline7500" ---ImHO i rekon your problem to be a choked intercooler or something along those lines,if not a choked fuel filter,
the spec acording to auto data for the boost is .7 bar for the discos & just under that for the defenders,

I am rather hoping that it's the intercooler - as that's pretty easy to fix [-o<

Isn't 0.7 bar the rating for the 200TDi? Haynes gives a range of 0.8 - 1 bar for the 300TDi. While driving tonight, the gauge showed a tad over 1 bar ... so I'll take that as a positive :wink:  :lol:

I've been stuggling with mine for ages, can you tell me how you did it?

It's very hard to see - take off the pipe between the air filter box and manifold/turbo. Behind/underneath the inlet you should see a connection with a pipe going towards the engine and one going off around the back of the engine.

The one going towards the engine is the bigger of the two and is the one you need to connect into. My gauge came with a t-connector - I cut the pipe around the middle and inserted the t-connector.

Next problem - how to get the pipe (to the gauge) into the cab :roll:  I found a grommet right behind the screen washer bottle. I pulled it out and "modified" it with a knife to allow the pipe to also pass through without getting squashed. It comes out underneath the glove box.

Mine is currently held against the CB with an elastic band :lol:  I plan to find a more permanent home soon!

Thanks,

Glad I can just add it straight into the pipe, I really didn't fancy drilling and threading the inlet manifold (lots to go wrong with disasterous consiquences. :evil: )

I definitely owe you a pint (or several!)

 :lol:

This is another one learnt on MArine Diesels:

If your boost is higher than anticipated look at where you are taking it, if you are measuring before the Intercooler (which is hard to tell from the description) then you do have a very ggod turbo but the air is not getting to the engine. Basically the airflow is getting choked in the intercooler giving a hight turbo pressure and not enough air to the engine.
