the boost compensator adjusts the pressure at which extra fuel is delivered so if u set it soft u get full fuel at about 0.1psi and totally remove lag, I just ran mine without any spring in the end.
Thank god a person who actually knows about turbos!! Namely the extra charge temperature negating the extra boost. I read another video comment and someone said "disconect wastegate!" for max boost!!!! With standard cooler - bad idea, although on my ford 1.8td (forgive me!) the wastegate was seized for ages, 25 psi boost, I reduced to 18 and have same power I think. Just fiddling with air leaks on filter head, I have had 6 faulty new chinese ones! Be on lookout for these!
lucas pump u screw it out as the screw squashes a spring that resists compensator, stiffer spring the slower it gives extra fuel, screw it out(anti clockwise) and it can move easier so u will get a bit more smoke off boost or at low/ beginning of boost.
Good info, thks. Adjusting the shown maximum fuel adj 4mm allen screw helps also in old -88 ducato j5 N/A 2.5D Lucas CAV MA260 DPA344 ...now pump is giving enough juice (when fuel adj screw had no effect...). With new injector nozzles it did not once give one bit of blk smoke - after turning the screw 60 degrees, power is now 'normal' with a hint of blk smoke at full throttle. Engine has 100k miles.
Any diesel specialist should have one. I have never removed one without destroying it! with 1 exception, U can try filling plug with epoxy and glueing in a piece of plastic bar etc, so u can turn bar to remove plug rather than ruining plug, I tried this once and it worked but be sure to get no bits inside pump.
@ExtraSilver Yes, they both have turbos. The Dturbo engine is an older, more simple mecanical type engine whereas the HDi is a more efficient and modern common rail type engine.
@shanfer123 i have the same car and it has a turbo as stock.. when you put your foot down have a listen towards the passenger foot well.. you can hear it whistling down there and you can hear the little stock dump valve when you come off the throttle..
Depends what you mean by stage 2, there will be a video about mounting a front mount intercooler and uprated injectors, as well as advanced pump tuning.
Theres not reli alot you can do about turbo lag, best thing is to get hold of a later GT15 turbo, they have smaller internals, and spool up a lot faster, i did the conversion on mine, feels more like a petrol to drive now
@MrBezelder the compensator decides when u get extra fuel on boost so if u set it soft u get full fuel at low pressure, this means that even more boost can be made and so on so it removes lag totally, do it, do it now!!
Well you should change the injectors from lucas ones to bosch ones really for best perfoance as they have totally different presures to make them open. And you just need to change the pump / bracket / injectors, and to make it easier, the lines as well, as bending them isnt ideal..
Yeah thats fairly normal, the system is always full of oil mist from the oil breather, but excessive oil can be a sign that ur turbo bearings are on there way...
Ah right. I guess I'll have to suffer then unless I get myself a dump valve. Having fun with dead injectors at the moment, it sounded a lot like the "killing" video you put up earlier in the week when trying to start. It hurts my soul to hear her like that! She runs in the end though, yesterday morning it took 5 cycles of plugs and cranking to get her to run. Any idea where I can get replacement injectors if they turn out to be beyond reconditioning? Also my exhaust is falling off now... Fun!
Cog wheel? Just a bolt squashing a spring?. Or was I asking about the bosch pump? I cant recall! This vid is very informative though. I turned my pump up to max and still no smoke! The bosch pumps; u can use a small screwdriver to prize off tamper cap.
Boost compensator is used for the on boost compensation but also effects off boost kind of. ie u can significantly reduce turbo lag by allowing compensator to start compensating earlier (lower boost) as u know, to me it makes the car a different drive totally, no extra power but much less lag. What say u?
cant say what sort of a power increase you will have, all depends on the tune you gave it, but with a really good tune you can get up to 150hp before having to change parts
Yeh ur HDI seems a beast :P am going for power with mine, am front mounting atm, have uprarted injectors, GT15 / bosch conversion. Should have a more detailed video soon.
Hey chap, Being an escort, i assume its a lucas setup, the compensator settings dont do a HUGE ammount on the lucas, your might see small gains, but nothing like you do from the bosch setup.
hi daz just like to say your a legend up here in the north of England ..... we have a problem 1998 d-turbo sport uses neither of them turbos has a waste gate arm but no adjustment like on track control/waste gate arm on your vids ....any idea looked really closely neither of the kkk or the other turbo you show is simular or same
You can increase the fueling with the max fuel, but tbh, you wont get much more from the 1900 nasp engine...without the turbo, you simply cant burn the extra fuel.
I wonder if the insurance company could tell if pump is turned up and wastegate adjusted? If u set boost then remove boost gauge, everything will look standard, I mean its an adjustment not a modification, unlike a chip on common rails etc? I wonder if u could class it the same as adjusting timing on a petrol car? see my point?
hey man, nice DIY video you've made! just want to ask you this, did you change anything on the boost compensator? i've increased max fuel on my escort td but i didn't changed the compensator... thanks!
hi great vid. fekin amazing very usefull thanks for takeing the time to create!. i am soon about to preform this performance tuning of my 1.9 td 306 but firstly i must invest in a boost gauge. but the 1 im looking at will messure up to 20psi.. is that all it needs to b on the gauge? like will the gauge cover the pressure reading the turbo is going to create ,, 20 psi .. ?plz reply thnks
Great little video. Just a quick question... I'm using a D8B 406 engine in a 306, with a Bosch Pump, I altered the settling earlier and my tickover revs have lifted to 1100 rpm. I take it this is due to the side adjustment (max fuel). I wound it back, but does this sound about right though? It had in the past been "stage 1" tuned but
My Dturbo came with the "Grenade" in the boot and some cut up pipes on the pump can you help??? also someone has grinded/cut away some of the metal off the top of the pump and there is a switch with lots of cables coming from it???
Gotta love the d turbos and the great work Darren does I’ve seen some of his builds what inspiration I get out of it but my d turbo is noway as fast as his lol come check my video 👍
If lucas pump increase off boost fuelling by adjusting boost compensator screw. Have u fitted a huge turbo by any chance? Is the standard turbo (if fitted) working properly? Look for lots of oil in inlet tract - worn turbo.
i have tuned my pug and i must say it has made a massive differance also i have put some capri 2.8 rs wheels 13 inch 205 wide on and that has gave me a little bit more on acceleration aswell...just a quick question mine is the 75bhp phase 2 model so with this tune roughly what sort of bhp would this of added you think? thanks for sharing the video and for those muppet's keep asking the question about the rotation of the boost to turn it up if you listened he did say anti-clockwise in the video.
hi, i know these are similar to the old 1.8td mondeo's setup. however, i have a mk3 mondeo tddi with a fixed vane mechanical turbo. theres no throttle cable on these so any tuning for that will need to be done on a remap via the ecu. given i have a mechanical turbo as apposed to the variable vane which relies on a lot of electrics, im wondering if you can help me out to get more out of the turbo. i can get pictures if needed. Thanks Darrell
nice vid but what about egt's with too much fuel?? also can you not spin the daiphram around to the wideist part to give more on boost fuel rather than doing up the top bolt to push the daiphram down abit
Someone sent me a message asking about tuning yesterday, i have accidently clicked delete, and cant find who it was, PLEASE message me again if u get this messag!
I'm in camborne cornwall and got a 306 with a lucas pump. its not turbo but is it the same think for adding more disel. (looking for more low down power as i tow alot)
i removed my cat and middle box and had a straight threw pipe {no cat & middle box} into a cobra back box plus the stage 1 tune and now im running over 22psi from 16psi with only grey smoke..unreal upgrade and you can hear it spooling. i now want to have a 306 hdi gearbox fitted,what modifications need to be made or is it a straight fit ? also it is a 90hp its only the non turbos that are 75hp as i reacently found out.
@darrenjlobb Hello. I have a ford 1.8td engine which has the lucas pump and the gt1544 turbo. I have fitted a front mounted intercooler and shrotened the wastegate rod, also the wastegate hose is disconnected so it makes boost according to fuel injected. I have also turned up the fuel from inside the pump and I think that the screw can't turn no more. Which the boost is limited to 17 psi and also no smoke at wot. Is this the max fuel that the pump can inject?.
can you fit a bigger turbo from garrett to the 306 d turbo ??? and wich one ?? my boost is on max now and i wanna have more !! need a bigger turbo !! ;) grtz
Alright mate do you know how to fit a dump valve for this car I'm trying to help my little brother fit one to his? Where does the little pipe go to, off the top of the dump valve if you get what I mean? Lol
wind it all the way out, take off the springs, cut the bump stops in half and drop her 6 nicks on the back. rubbing scarping and smoking like a board house wife
just a quick one again...i have turned my max fuel up on a lucas pump over 90 degrees. the nut on my acutator on my kkk turbo was loose so i turned it all the way in and then back out 1.5 turns and i am only seing 16 psi...any ideas ? should i go more with the max fuel ?
Ive got a 1.8d old fiesta. it has a lucas pump but without boost compensator. there is a screw on the back of the pump by the outlet pipes. I know the max fuel is inside the pump. But what does the screw on the back of the pump adjust?
why don't you just undo the 4 screws holding the top of the pump on and mark where the diaphragm is remove it take the plastic washer off the refit and turn it between 90 and 18p degrees that's what we do with tdi landy's running ve pumps or fit a boost pin and go from there

Yes, you can run the bosch on oil, and also, its a much nicer pump to tune, leaves you with a much smoother, and less smokey engine :D
@ExtraSilver Yes, they both have turbos. The Dturbo engine is an older, more simple mecanical type engine whereas the HDi is a more efficient and modern common rail type engine.
You are correct yes, i am yet to get round to making a video regarding ajustment of the cog wheel within the compensator disphram..
What’s the code for the Lucas pump I can’t find the same one anywhere
@shanfer123 i have the same car and it has a turbo as stock.. when you put your foot down have a listen towards the passenger foot well.. you can hear it whistling down there and you can hear the little stock dump valve when you come off the throttle..
@ExtraSilver No problem, Congratulations! I have just turned 17 so not long until mine :)
Depends what you mean by stage 2, there will be a video about mounting a front mount intercooler and uprated injectors, as well as advanced pump tuning.
great work mate, we live for these things in northern ireland, mainly cause we're all drivin them on red :D
Well to start. Tell us where you are and we may be able to help find you a good place to go.
Turn the "max fuel" screw anticlockwise, give it a turn, and see how it looks, yes it will fail MOT if its excessivly smokey.
Theres not reli alot you can do about turbo lag, best thing is to get hold of a later GT15 turbo, they have smaller internals, and spool up a lot faster, i did the conversion on mine, feels more like a petrol to drive now
Eagerly waiting for part 2! =D
Could you possibly do a video on how to reduce turbo lag? Its seriously beginning to p*** me off now!
this guy is sick, which to you means very good
@MrBezelder
the compensator decides when u get extra fuel on boost so if u set it soft u get full fuel at low pressure, this means that even more boost can be made and so on so it removes lag totally, do it, do it now!!
Well you should change the injectors from lucas ones to bosch ones really for best perfoance as they have totally different presures to make them open. And you just need to change the pump / bracket / injectors, and to make it easier, the lines as well, as bending them isnt ideal..
Yeah thats fairly normal, the system is always full of oil mist from the oil breather, but excessive oil can be a sign that ur turbo bearings are on there way...
In Northern Ireland the black smoke 'reek' is the best bit about dturbos
Ah right. I guess I'll have to suffer then unless I get myself a dump valve.
Having fun with dead injectors at the moment, it sounded a lot like the "killing" video you put up earlier in the week when trying to start. It hurts my soul to hear her like that! She runs in the end though, yesterday morning it took 5 cycles of plugs and cranking to get her to run.
Any idea where I can get replacement injectors if they turn out to be beyond reconditioning?
Also my exhaust is falling off now... Fun!
this vid was great, lookin fowards to next one. cheers. ps, see my 150bhp 306?
Cog wheel?
Just a bolt squashing a spring?.
Or was I asking about the bosch pump?
I cant recall!
This vid is very informative though.
I turned my pump up to max and still no smoke!
The bosch pumps; u can use a small screwdriver to prize off tamper cap.

It would if the boost pressure is leaving the gauge area....via a possible leak.
Hey chap,
Being an escort, i assume its a lucas setup, the compensator settings dont do a HUGE ammount on the lucas, your might see small gains, but nothing like you do from the bosch setup.

thanks!
@PugMarshall2906 ah sweet thanks :P .. just passed my driveing test a hour ago also.. cant wait to drive now :P thx
Do u have any pics of ur engine bay, the same concept applies to all mecanicaldiesels... jsut depends on pump and turbo..
FROM THE CORNNISH DERV DR HIMSELF!!!

best looking wheels for a 306
i have a dturbo s, not sure if im up for messing bout with it like that tho
My Dturbo came with the "Grenade" in the boot and some cut up pipes on the pump can you help??? also someone has grinded/cut away some of the metal off the top of the pump and there is a switch with lots of cables coming from it???
hi darren, on the bosch pump the boost comp screw on the top, do you turn it clockwise or anti-clockwise? great video :)
I clearly show where the max fuel screw is in the video...
interesting!, what hp and torque do you hope to make?
mine makes great torque at 260pounds foot!
I gotta do this to my 406 2.1 TD, neeed more power
Gotta love the d turbos and the great work Darren does I’ve seen some of his builds what inspiration I get out of it but my d turbo is noway as fast as his lol come check my video 👍
If lucas pump increase off boost fuelling by adjusting boost compensator screw.
Have u fitted a huge turbo by any chance?

nice vid but what about egt's with too much fuel??
also can you not spin the daiphram around to the wideist part to give more on boost fuel rather than doing up the top bolt to push the daiphram down abit
@doorbell65 anticlockwise. "exactly the same as the lucas pump"
@ExtraSilver It's still a turbo though.
Someone sent me a message asking about tuning yesterday, i have accidently clicked delete, and cant find who it was, PLEASE message me again if u get this messag!
I'm in camborne cornwall and got a 306 with a lucas pump. its not turbo but is it the same think for adding more disel. (looking for more low down power as i tow alot)
There is a language convertor on youtube evidently, something to do with copying and pasteing and translater?
The reason u cant find it, is because its a mecanical injection derv, it dosnt have one!
i removed my cat and middle box and had a straight threw pipe {no cat & middle box} into a cobra back box plus the stage 1 tune and now im running over 22psi from 16psi with only grey smoke..unreal upgrade and you can hear it spooling.
i now want to have a 306 hdi gearbox fitted,what modifications need to be made or is it a straight fit ? also it is a 90hp its only the non turbos that are 75hp as i reacently found out.
No worries :)
Hello mate i really like your videos and channel i have a fiat bravo TD 100 with a lucas FT 09 can i do the same thing in this pump ?
Thank's mate
on the lucas pump on the boost aqutator when you slacken of the lock bolt is the bolt that you mentioned inside an allen key or a torque ?
@shanfer123 i have the same car.. its a HDI not turbo and its 91hp not 70
Guide doesnt show anything about advancing the timing on the lucas ot bosch, aswell as diaphram inside the pump and the LDA pin
@darrenjlobb

@PugMarshall2906 so the HDI has a turbo also ? :P
Does the boost compensator rubber thing from the inside support any ammount of boost before it bursts?
hi please do you think you can tell me where the inlet air tempriture sensor thing is please,i wnt to mod it but can find it on the dturbo 306
can you fit a bigger turbo from garrett to the 306 d turbo ??? and wich one ?? my boost is on max now and i wanna have more !! need a bigger turbo !! ;) grtz
Do you know if there's anyway to turn up a fiesta 1.8TD the ones with no throttle cable (Don't want to change pump)
Alright mate do you know how to fit a dump valve for this car I'm trying to help my little brother fit one to his? Where does the little pipe go to, off the top of the dump valve if you get what I mean? Lol
the allen bolt inside the pump will not move what do i do
lucas pump
Hi Darren.
I have a Citroen zx 1.9 non turbo. Is there a way tune it up without putting a turbo on it ?
wind it all the way out, take off the springs, cut the bump stops in half and drop her 6 nicks on the back. rubbing scarping and smoking like a board house wife
just a quick one again...i have turned my max fuel up on a lucas pump over 90 degrees. the nut on my acutator on my kkk turbo was loose so i turned it all the way in and then back out 1.5 turns and i am only seing 16 psi...any ideas ? should i go more with the max fuel ?
do you now how to tune a 406 2.0 hdi too?
i need: more diesel and more pressure, its a bosch pump.
i hope you can help me!
are the two manifolds the same mate ?
so if i have an adapter plate made will it fit both manifolds ?
thank's mate.
hi iv got a meridian 4 door 306 turbo diesel but it only has 70 bhp. can i pay u to do the turbo 4 me ??
which way do you turn the componsator on the bosch pump
hey ive just done this to my car, any idea what type of power it will be producing rufly? thanks
Will this work on a non turbo model ?
about to do a Bosch conversion on my 2.1 4o6, do you no what sort of settings I should do for the fuel/air
why is the better bosch pump on earlier models?
can turning up the pump too much affect performance?
I am based in Cornwall
Just found you on fb lol
Im afraid i dont know anyone german to help me out on that one...
What would be the limit you could do to get lots of reek
And would you need to turn the turbo up aswell
Do it yourself :P This video explains it all
what sort of MPG will it do after tuning ?
Ive got a 1.8d old fiesta. it has a lucas pump but without boost compensator. there is a screw on the back of the pump by the outlet pipes. I know the max fuel is inside the pump. But what does the screw on the back of the pump adjust?
also i am currently making up a manifold to mount a rover 75 2L td t3 turbo. will the lucas pump surfice to make a nice daily driver with low boost?
why don't you just undo the 4 screws holding the top of the pump on and mark where the diaphragm is remove it take the plastic washer off the refit and turn it between 90 and 18p degrees that's what we do with tdi landy's running ve pumps or fit a boost pin and go from there
Are you sure its a turbo diesel? There was no such thing as a 70brake td...
Do u live anywhere near peterborough so i can pay u to tune my car
nah it is turbo on the dyno its only 70 break tho ?? i need to make it faster lol
What bhp is expected at 18 psi
my pump looks different
and it is diesel..
u mad??
NO SMOKE NO POKE
