Absolutely correct.
I suspect there's a small fuelling anomaly in there somewhere.
He'll find it soon.

Turbo checked, and spins nice and smoothly. I did notice a bit of play I'm guessing about a 64th of an inch.
What kind of fueling anomaly did you have in mind CharlesY - go on , give me a clue
I have to admit the truck is running soooo much better without an exhaust
I have ordered the middle section - but boy is she loud with the throttle open
Certainly feel I'm making some sort of progress.

That's about right then. The turbine and impeller are one on each end of a skinny shaft, which runs inside a plain bearing which floats loosely in the turbo casing. As long as there's a plentiful flow of oil, all will be well.

I suspect "not enough" to match the extra air - yet.

To update.
Fitted the straight throught stainless centre pipe, with the Paddocks mild steel back box - a big improvement, but still a sense of gas being resticted.
So, I'm now driving it with out the back box - and the truck is driving great again, in the that its smooth and torquey - but a bit ' throaty'.
I have a feeling Paddocks have sent me the wrong system for my engine.
Searching the net I find this back box for a 1993 tdi 200 ( same as mine)
Land Rover Defender 90 200 Tdi parts, spares
And this is the same Paddocks have sent me, the Land Rover Parts Shop are selling for later 200 TDi's
ESR2382 - Rear Silencer and Tail Pipe - Defender 90
So, what do I do?
Do I get the rear pipe for my engine with no silencer, but then then there will be no silencer on my exhaust at all - will this pass MOT's, and will the tail pipe reduce the noise levels enough to be liveable?
Or is the Paddocks rear box OK for my earlier TDi !
I'm certain my valves need some adjustment, but I'm not sure how that would interact with the exhaust - if you know what I mean.
CharlesY - what checks should I be making with the fuel end of things?
Yours confused now!!

Your valves have TWO adjustments, clearance and TIMING.
Let's hope YOU set the clearances properly, and that someone else set the camshaft belt timing perfectly. Who fitted the belt last?
CharlesY - what checks should I be making with the fuel end of things?
Maximum fuel delivery setting of course as this does limit the maximum POWER no matter what else you do, but unless this has been "touched" it is unlikely to have moved. That really only leaves you with the usual suspects of fuel filters, air leaks, the turbo boost diaphragm being a bit sticky, and the ultimate question - perfect injection pump TIMING set for THAT engine by patient trial and error.

i think the general consensus is turbo engines run better with no exhaust at all so anything to reduce the noise will lose a few horses.
you could fit any backbox from any car in theory, my recommendation would be a single straight thru box and stuff the extra noise......its a land rover its supposed to make a racket

I would suggest that instead of "you could fit any backbox from any car in theory" should be "you could fit any backbox from any car of the same engine capacity and rev range" - it needs to be able to take the volume of exaust gases generated.
yes i agree, thats why i said 'in theory' it wasn't a recommendation, as long as it flows nicely and is not too noisey then it could be a winner.....it dosn't nessesary have to be an original land rover part.
Hmmm, why does a TD5 backbox on a straight through system attached to a 3.5 V8 sound and perform better than anything else
its a V8, it would sound perfect with anything attached to it
its a V8, it would sound perfect with anything attached to it
That depends upon the configuration of the crankshaft.
It can be a "single plane shaft" which makes lovely V8 burbles or
a "Two plane" shaft which just sounds like a straight 4 going twice as fast.
Bet you didn't know that!
CharlesY
eek your right i dodn't know that, i assume its the old rover v8 which is a single plane i think!!! dont shot me if i'm wrong its a 50 50 chance

Ok folks I thinks I have sorted it.
Had to go up to North Devon the night, so without rear box gave it a bloody good blast up the A30, Geez was it loud, and hot!
And I also made sure the wastegate , and actuator was moving freely as it should- put the rear box back on, made everything was tight, and sealed - touch would she's now running lovely - super smooth, and very torquey, apart from the tappets which I know need some adjustment, but I'll sort them out later this week.
But fingers crossed I think I have sorted her out.
I reckon a good blast has freed removed some crap, and helped free anything that may have been sticking.
Thanks so much for everyones help.
I have have to say this forum is bloody great - it gives you the motivation to get on , and sort the problem, when your ready to give up - and in the process your learning about your Landy and how it works.
Thanks

DAMN!
You get to keep your money!
But do you know why the V12 RollsRoyce Merlins made such a wonderful sound?
A V12, but only SIX conrods have big-end bearings ..... work that out!
