Car Forum / Land Rover Cars / June 2007200Tdi seems a little sluggish
Got a 200Tdi fitted into an 89 RR, seems a little sluggish on the motorway. Has trouble maintaining 70mph up gentle hills, and not as much pick-up as i'd like mid-range. Thought perhaps it might be turbo. No oil or smoke, but the turbo doesn't seem to kick in like previous TDI's i've driven. Anyone got any ideas? If it was a petrol I'd know what to poke around at, but a 200Tdi I have no idea.... Alex >Got a 200Tdi fitted into an 89 RR, seems a little sluggish on the >motorway.

But at (say) 3000 rpm, the engine is pumping 3000 x 1.25 litres per minute of air through the turbo impeller, and that must be generating airflow in the compressor. Now, if you had a very clever turbo it could idle when not needed, and only generate boost when the engine is under load, and this would probably be more efficient... But I don't think they fit ones like that. I've revved turbo ones in the yard with the bonnet up and noted the hoses getting fatter, so I reckon it boosts any time the engine's up to speed, meself. >Check there are no exhaust manifold blows while you're at it.

The transit TD here has the same problem, and when the manifold is blowing it don't pull so well. Unfortunately, the simple fix (gun gum around the joint) doesn't last all that long - but the proper fix, which is to remove the manifold, clean the joint and re-seal it (it doesn't have a gasket), would take about half a day, whereas the simple one takes 5 minutes.

I'm not arguing that it'll produce full boost off-load. But it's still a fact that just by rotating the engine pumps a goodly wedge of air through the impeller, which must generate some boost. The difference when it's burning fuel is that you not only get the balance of the input air going out of the exhaust but also the combustion gases. You're quite correct that what you need to measure is maximum boost, and it'll only do that at full chat. Or, more accurately I suppose you need to measure the revs at which the wastegate opens, on a normal sort of engine.

Er, not quite. The engine doesn't have to be under load but does need spinning up. It'll produce more than enough pressure at rest if you take off the hose and put your hand over the turbo outlet. Rev the engine and there should be a fair bit of pressure on your hand, similar, oddly, to an exhaust pipe pressure.

FFS if you don't understand the workings of something please at least STFU rather than disseminate misinformation to people looking for help. To check for a turbocharger problem you need to check for maximum boost which can only be done under load - free revving will not produce any significant amount of boost. > >>> Reading some of this coupled with Hughs comments above is lending me > >>> to suspect there may be a problem somewhere in the wastegate to [quoted text clipped - 18 lines] > boost which can only be done under load - free revving will not produce > any significant amount of boost. Nice one EMB, you don't mince words. The important point is when the engine is under load it's burning a lot more fuel, and producing much more expanding exhaust gases which drive the turbo faster, turning out more boost. You need to T in an accurate low pressure gauge to check how much. Martin > Nice one EMB, you don't mince words. I'm never keen on being told I'm wrong when I've given correct advice.

You need to T in an accurate low pressure gauge to check how much. The first bit of advice to anyone with a turbo engine experiencing issues should definately be to fit an accurate boost gauge. until you know what the boost is you are just guessing at other causes. In my saab, to set up my max boost I always go for a steep hill and then thrash it up it ensuring i get to 4th gear (top in my car). -- http://www.101club.org The 101 Forward Control Club and Register >>Nice one EMB, you don't mince words. No he doesn't does he? However, I will at least remain polite in my reply and hold a faint hope that an apology may be forthcoming. I quote the original poster: " at least I can see if the turbo is actually producing any boost. " My test will tell him exactly if his turbo is producing ANY boost. He did not ask for an accurate method of measuring boost. TonyB >>>Nice one EMB, you don't mince words. > [quoted text clipped - 9 lines] > >He did not ask for an accurate method of measuring boost. well, true. To check for "any" boost, you open the bonnet and rev it up to about 3000, and watch the outlet hoses from the turbo, which will get fatter. However, it's pretty unlikely to produce no boost at all without other symptoms, so you really do need a max boost check. Since most of them regulate boost with a wastegate, knowing at what revs the boost stabilises at the preset level is also useful - if the turbo, for any reason, is a bit lacksadasical then it might still get to the book value for boost but not 'til a higher speed.

I would agree with this. I had a Volvo turbo with a boost gauge on the dash and I was surprised to note that that cruising down the motorway at 70(ish) there was virtually no reading at all.

I'm afraid you may be under the same misapprehension that EMB is under Hugh. While crusing at 70 you'll have a low throttle opening which results in low exhaust gas pressure, thus the turbo will not spin to full speed. Opening the throttle with an increase in gas flow will spin up the turbo but a load on the engine is not necessary for this to occur. TonyB > I'm afraid you may be under the same misapprehension that EMB is under > Hugh. [quoted text clipped - 4 lines] > spin up the turbo but a load on the engine is not necessary for this to > occur. Patently untrue Tony. And I'd really appreciate if you'd stop spreading inaccurate information - maximum boost will not occur without close to maximum load (proven over the weekend in several different vehicles ranging from 2.5 to 16 litres displacement, and max boosts from 0.5bar to 4bar). > Patently untrue Tony. And I'd really appreciate if you'd stop spreading > inaccurate information - maximum boost will not occur without close to > maximum load He's not claimed that it does, he's just said that you'll get *some* boost, not max, so you can at least say that the turbo is spinning. I've seen the same on my old lotus, with no load the boost gauge will give a reading when you boot the throttle in neutral but you don't get much until you're in gear and underway.

As turbo problems are commonly related to worn axial thrust bearings you need to run them up to significant boost to put a high axial load onto them to check. The same applies to a sticky wastegate - maximum boost is often all that is affected. > As turbo problems are commonly related to worn axial thrust bearings you > need to run them up to significant boost to put a high axial load onto > them to check.

It can certainly help, but when a vane fell off mine, just a simple no-load test was fine, under no load you could hear the bloody thing, sounded dreadful ;-) But anyhow, it was your moaning at him for saying something I never saw him say that bought me into this, and as it's a hot sweaty evening, I'm off to finish my beer, enjoy!

We were not talking about maximum boost as you'll see if you read the posts properly. The OP wanted to know if he was producing ANY boost as he said. My test is easy cheap and works, I didn't say it would measure boost accurately but it will tell him if he's getting boost at all. Further, you said "It'll only produce boost under load." which is the most patently untrue statement in this thread so far. Load has nothing to do with boost. Of course you'll get max boost under max load but not because of it. I would really appreciate it if you'd stop slagging me off without good cause. Please, read the posts first.

Point one, the OP did not ask about "significant" amounts of boost, he asked about checking for ANY boost. My test would have told him that he was getting some boost or no boost.

Point four: Call me touchy if you like but he said "FFS" and told me effectively to shut up unless I knew what I was talking about. If that isn't slagging me off I don't know what is. Point five: Perhaps you could explain then, why an engine turbo is affected by load on the engine to any degree and why my 300 TDi produced enough boost at rest with the pipes off to almost prevent me from holding my hand over the pipe?

If there was no "significant" amount of boost, it would be a waste of time fitting the turbo in the first place, and it needs to be checked under load. Yes, I concede your test will show the turbo is actually working to a degree, but it needs to be checked more accurately. > Point two: I have already said, Hugh's Volvo produces little boost at 70 mph > because he has a low throttle opening and > low exhaust gas pressure. What are you trying to say here? Why do you say that Hugh is under a misapprehension?, you have made the same statement which is correct. And after making that statement, how would do you think you would generate the boost in that situation, say, to possibly overtake something? and would the engine be then under load? And why does that alter the boost? > Point three: The statement that "It'll only produce boost under load" is not > helpful, it is wrong. Dare I say this? FFS Significant is the operative word, it is a waste of time running an insignificant test therefore the engine needs to be under load to test for boost pressure.

My test will produce enough boost to virtually stop you holding your hand over the outlet pipe, I know it does I have done it, if you don't believe me go and try it. that amouint of boost certainly qualifies to answer the question of "any" boost and to my mind also answers the question of "significant" boost. >> Point four: Call me touchy if you like but he said "FFS" and told me >> effectively to shut up unless I knew what I was talking about.

However I have a turbo sitting on my bench that will 'produce boost' according to your test, but the moment it is subjected to any significant load will promptly bash the exhaust impeller into the housing and cease to turn (and thus no longer produce boost).

The LR workshop manual says the following for testing the boost on the 300Tdi. I would assume the principle (if not fugures) for the 200Tdi would be the same --> "To check maximum boost pressure, drive vehicle normally, but in such a manner that full throttle can be maintained whilst climbing a hill with engine speed held steady between 2,500 and 3,000 rev/min. Under these circumstances boost pressure should read 0,95 - 1,09 Kgf/cm2 (13.5 - 15.5 lb/in2 )." Colin www.REEDX.net >The LR workshop manual says the following for testing the boost on the >300Tdi.

But it's true to say that the OP wanted to check for "any" boost, and for that you don't need to do the whole works. It might not tell you much, though, compared with a maximum boost test as above.

Max boost is the only way to tell if a turbo is working correctly - and most unburnt fuel problems only manifest themselves in an obvious manner at high boost pressures. > Max boost is the only way to tell if a turbo is working correctly - and > most unburnt fuel problems only manifest themselves in an obvious manner > at high boost pressures. Sorry mush but that's patently untrue, on my old car you could tell the turbo wasn't working properly even when the car was not under load, with the engine in neutral, booting the throttle produced the most godawful sound from the turbo as it was missing an exhaust vane, the scraping sound was horrible. Testing for max boost is certainly important but to baldly state that anything else is worthless is just daft. You can check for some problems with a turbo just by spinning the thing by hand, every turbo problem does not need a max boost check to see if it's there or not. I've found a stuck wastegate by trying to move the thing by hand, no max boost check was needed to spot that one.

I think it needs taking in context. The OP stated that the vehicle felt "a bit sluggish". A mechanically fscked turbo which screams at anything over 1500 revs rather tends to self-diagnose: in that case, OP would have posted "my turbo makes a godawful noise[1], I assume that means it's shagged". The question as originally posed suggests that maybe it's not boosting as well as it should, and to test that, you do really need a maximum boost test as EMB said.
