Warm Air \ Cold Air
On a Turbo diesel xud9te engine would having the air intake pipe to the turbo and from the turbo and to the intercooler make abig difference in performance keeping the air cold? if this is possiable does any body know where i could get parts ? i live on the isle of wight so i am limited to places unless they deliver.

Try giving the back of the intercooler a good wash through, with a strong hot jet of water. Dead flies block them up and a good deal of gunge invariably gets removed, allowing better airflow and therefore reducing the temperature rise in the intercooler. The engine will now pull for longer on boost. The results are usually immediately noticeable.

If I understand what you are saying, you are asking whether it is worth while lagging (or otherwise insulating) the air intake pipework under your bonnet.
It wouldn't make any difference, since the air gets heated up being compressed and by the turbo (which tends to get hot since its on the exhaust). I'm not sure whether you could actually lose performance since the air in the pipes could be hotter than the air in the engine bay.
Intercoolers improve efficiency, and there is no doubt in my mind that cooler air going into an engine improves efficiency and power output whether the engine is petrol or diesel.

i cleaned the intercooler like Tom said (did that at the Weekend)but i found no noticable improvments and the car still takes awhile to repond. is there any way of cleaning the insides of the air intake witout striping it all apart,like an air cleaner to remove dirt inside the system? (hope this makes sense?. on another note iam i looking at the wrong end ? i mean could there be a blockage in the exhaust? Restricting gas flow?

The turbo can have a surprising amount of lag if you drive at low revs. Have you tried your car out against a similar one or has your power gone down noticeably? Performance issues on a newly bought turbodiesel are usually addressed as follows:1, change all three filters and the oil. 2, add a bottle of RedeX to a tank full of diesel. 3, fifty mile Italian service. Exhausts soot up and many owners simply don't give them enough welly from time to time.
My BX was good for about 95 when I picked it up and after a fast 100 mile run, it was a lot faster!

i'll do a service on it, put redx in my fuel tank and prime the fuel filter with injector cleaner. but i cant do a fifty mile run because on the I.O.W there to many bends by the time i hit 60 i got to slow down for a bend!!
is there any stuff i can buy to put into the air system to clean all that as well?
Thanks for your help

You shouldn't hear the turbo at all. Tighten your exhaust and check that the plumbing is all tight. You may have dislodged the boost pipe to the fuel pump.
Don't try any "cleaner in the air system". You'll probably get a hydraulic lock if you do. Taking off the intercooler, sloshing a pint of petrol around it, then draining and replacing it is the best you can go for.
