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...

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

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

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

scrooge, could you check how many tooths the crank pulley of the tdci has? That way we could see if the tdci pump makes the same revs. The pump pulley is also 40t like the renault one.

Although a smaller pulley would be far easier imo, only have to use spacers to remoce the slack on the belt because off the smaller pulley. 40>30t would make a difference of 33,3%, let's assume the original pump is good for 125bhpx1,333=166,6bhp would be more then enough for my goals :) then...

I have a good used dci pump on the way for mine as i get the "fuel pressure low" warning sometimes at idle or when i take off. i'll try to source a tdci one too so i can compare them. Maybe it's just different revs and a feed pump that makes the difference... where did you have yours mapped...

Some interesting info in here : http://mdiesel.ho.ua/templates/MDiesel/zap/cat/DELPHI%20Common%20Rail.pdf although the 2.0 pump looks the same the pn is different so could be flow rates are different. however since all the pumps look exactly the same on the outside i guess internals could be...

You're right mate but maybe if we bundle forces we could get somewhere :)

But as i said before, the 1.8 tdci doesn't have 4 outlets...

Quote: The high-pressure pump on a common-rail system does only one thing ... pressurize the fuel in the fuel rail. It has nothing to do with injection timing, it just pressurizes the rail and holds the pressure at a regulated setting. Injection timing on a common-rail engine is done purely...

I don't get it! If they aren't timed why couldn't they be 180* out?

That's good! Search "mk1 focus tdci pump" on google and you'll see the one i mean.

I would think it won't be a problem on a commonrail system though? With pump injection the compression strokes pop the injectors at the right moment. Commonrail supplies a continues pressure i would think? the bosch pump fitted to the eco4 models has 30teeth instead of delphi's 40teeth thus...

I see a hybrid pump coming!

The pump looks exactly the same to me except for the mounting points and pulley mounting...

Can't find any flow rates on the net regarding delphi stuff, however the power the tdci's make should indicate they're enough. could be the tdci bottom pulley has more teeth so the hpfp spins faster thus flowing more? or because of the lift pump...

Could a moderator please move these posts to the above mentioned thread? Cheers!

I know the dci isn't the most popular but as it's a pretty economic daily which could use some more power i thought i'll start this thread to gather info on tuning these little dervs. so far the main problem seems to be the fuel pump that isn't able to flow more fuel then something along the...

Keep me updated mate! I was thinking along the lines of upgrading/modding pump and injectors, fitting stronger clutch and then get a decent remap.

Maybe it would be handy to make a topic about this matter? I signed up on cliodci.net too but there isn't much activity on there. i'm more then happy to try things but since it's my daily i can't do too much atm...

Pretty interesting matter though, not much info to find on this subject! i would be happy with just a remapped 100 but since the 106 is able to make 140-145 i'm convinced the 100 engine (which i think is the same internally) would be able to make those figures too! turbocharger should be able...

Little bit of a steal but i'm curious how much power you where able to make derv destroyer? How did you overcome the lack of fuel supply? I'm looking into tuning my 100 and i discovered 1.8 tdci have the same injector body and pump yet the fuel system is able to supply over 150bhp. Cheers!

Ayk2008, what happend with that engine? Look horrible!

Awesome car mate!

Had je spacers nodig voor de wielen?

This is my lap with the dci back in September: http://youtu.be/LHkcQsCMCFM 10th lap i've ever done and the first with this car. 2000+gt5 experience too. I don't look at laptimes, just have fun! Long straights i'm only doing 80's as i don't feel the need to go all out. (Dci probably won't go...
