Dci tuning thread

[Tutuur]

1400 for the 65/80 and 1600 for the 100. However we don't need that. The pressure doesn't need to be higher, it's just the flow capacity of the pump that needs to be higher.

tdci runs 1400 too

 

[Dr HMS Derv Destroyer]

That's ok then. One less issue.

1.8 pumps seems to be built better looking at owners forums.

Non chrome coated pump aswell ! WIN ! means it won't s**t itself all inside the fuel system

 

[Tutuur]

Lol, i guess we are on to some things! Will keep in touch if i find out more!

 

[Dr HMS Derv Destroyer]

Just emailed a diesel company that special with reconditioning and testing of the ford / jaguar group fuel sytems.

Hopefully I should get a graph or readout from a 1.8 TDCI pump on the test bench. Aswell as pulley sizes , Pump RPMs and feed pressure to The pump

If not, i'll buy a second hand pump, take it to be tested and then see where that gets us all.

Not to worried about injectors yet as its no good changin injectors without the flow to back it up

Just been out in the dci, was fairly fun, forgot how mad they sound with a straight through exhaust.

Mine sounds proper grumpy when going for it. Think the clearances on the valves are getting abit sloppy as I can hear them tapping under hard throttle.

I just love the turbo whistle

 

[Scrooge]

Can you see that video? I never can post photobucket videos lol The turbo whistle is great haha!!

 

[Dr HMS Derv Destroyer]

Yupp, actually the first one I've managed to watch on my iPad. Photo bucket usually won't work

 

[Scrooge]

Haha happy days.

 

[Dr HMS Derv Destroyer]

At least you've got the balls to go almost to redline. I'm s**t scared to even take it past 4200 LOL

 

[Scrooge]

Mine makes peak power to at 4300rpm lol they're a very strong engines tbh

 

[Dr HMS Derv Destroyer]

ive killed one so they cant be that bad lol

i cansee the uprated fuel parts might kill it as we dont know what they can handle

 

[Scrooge]

It's a shame this one will be going soon as I want to experiment with it but o well

 

[Dr HMS Derv Destroyer]

alwas buy a cheap 65 when we've found the right fuel mods

id have to buy a proper sport front end and another subframe before messing with it.

will a diesel cooler be benificial ? like the lads do to pd engines?

 

[Scrooge]

Didn't even know people used them on pd lumps, seems a bit excessive lol

 

[Dr HMS Derv Destroyer]

thy do for power builds lol im just thinking it could help the pump keep peak power. its a grey area but might aswell go all out if doing it.

forged engine will only happen if it cant handle llot more power past 130

 

[Scrooge]

££££££££s

 

[Dr HMS Derv Destroyer]

nah, it'll be the rods giving up, or the crank.

we'll see. i'll get mine mapped by paul rstuning , get the fueling right nd it'll be rate

might get a custom copper gsket made incase i run high boost. ( mini specialist can make to order )

 

[Tutuur]

If the tdci doesn't use a fuel cooler why would the dci need one

 

[Dr HMS Derv Destroyer]

I think they might Underneith near the tank.

Its abit like Citroen and peugeot have a little fuel rad near the tank aswell.

All I'm looking at is reliability of the system

 

[Tutuur]

always good to consider this kind of modifications!

btw, if you need a good intercooler try looking for a euro4 dci logan item. they're roughly the same dimensions as the dci 100 intercooler although they're 1,5x as high. i bought one for 90 euro's from daciashop.eu

http://www.daciashop.eu/dacia-logan-1-5-dci-euro-4-intercooler-8200409045

only need to make custom fittings but that wouldn't be too hard. still have to test fit but i'm convinced it'll work

 

[Dr HMS Derv Destroyer]

ordered one, it will work. allot more efficiant than the dci 80 intercooler anyway

 

[Tutuur]

Found it after searching part databases, measurements where given so i could make a good comparison.
i think the hose connection are a bit wider from eachother but anyway makes for a good priced intercooler

cost €157 here in nl but after searching the pn on google i found daciashop

 

[Tutuur]

just fitted the dacia intercooler, it's only mounted with a few zipties atm but i can tell you it fits like a charm!
only had to cut of a few small bits and it sits perfectly now.

made a few pics for reference:

 

[Dr HMS Derv Destroyer]

I'm still waiting on mine

looks good tho, better flow and cooling

 

[Tutuur]

and for half the price of a 100 intercooler

 

[Dr HMS Derv Destroyer]

Are then ends any different in size ?

 

[Tutuur]

No exactly the same, only the left one is a little bit lower so it was a bit of a stretch with the original hoses.

 

[welshname]

Quite an interesting thread this. After owning the 306 I'm quite fond of derv lols.

Didn't realise you still had the DCi, Ant. Was tempted to get one when I was looking for the 1.2

What's the difference on the 3 DCi's?

Iirc its:
65 - no intercooler
80 - intercooler but same turbo
100 - different turbo and different ic.

Are there no internal, pump, injector differences?

 

[Dr HMS Derv Destroyer]

65 injectors are different ( if one went it needed four down to some coding thing, they changed it later on so you could just swap the dodgy one )
80-100's share the same. Just fuel pressure ramped up to 1600 bar on the 100's

100's got a different gearbox aswell

65/80 have 25mm pins on the pistons
100 have 26mm

Led to beleive the crank is made stronger aswell

 

[Dr HMS Derv Destroyer]

No exactly the same, only the left one is a little bit lower so it was a bit of a stretch with the original hoses.

Ah right, I'd have to go full custom piping as mines still got 80 Ic pipes

 

[Tutuur]

Yeah true but that wouldn't be that hard. Arleast it fits decent between the beams etc.
or find yourself some 100 hoses which won't be easy

 

[Dr HMS Derv Destroyer]

I'll go custom, I've got some 2'' exhaust pipe knocking about, I'll make something up and use Samco hoses in between

 

[Dan@SJM]

Ffs I knew I shouldn't have read this thread. I'm determined to keep mine standard as I'm sure the engine isn't strong enough to be tuned heavily.

 

[Dr HMS Derv Destroyer]

That's the problem, non of us know what they'll take before throwing a rod.

They can take a beat in tho. Unless been treated like crap by no servicing since new.


Little update. Diesel BOB has got back to me via email. He's going to try get the flow rates of the three pumps i requested.

1.5dci
1.8tdci
2.0-2.4tdci

 

[Dr HMS Derv Destroyer]

Intresting,I think I know how the TDCI pump is so much better, with the help of this fella

http://delphi.com/manufacturers/aut...uelpumps/diesel-high-flow-transfer-fuel-pump/

 

[Tutuur]

Could be worthfull to try and fit a clio sport intank pump.

regarding the bottom-end, i'm lucky having a dci 100.

would be interesting what bob finds out! If it turns out the pump flow the same then probably it's because of the lift pump which would be great news!

 

[Dr HMS Derv Destroyer]

If it is, I'll try fit a cliosport lift pump and put the crdi injectors back in

 

[Tunst]

I have a 172 in tank pump if you need one.. Frw ££ postage and you can have it..

 

[Tutuur]

And then go for a mapping session again?

hopefully we'll find out soon. Only problem for me is i don't have anyone near to map it...

do you have an uprated clutch too Hms?
