    Do Large injectors mean diesel smell

    You can use BMW 2.5tds injectors (there are other engines to...) Wag IDI engine head doesn't handle extra heat from the fuel, BMW and MB are made from better materials. We have drive here on the icetrack with diesel long time, MTDI is the best choice.

    hard cold start after injection pump rebuild (EuroVan TDI (AHU) conversion)

    What is outside temperature when it is hard to start? Is there lack of power when accelerate? Make a video of engine and tailpipe on a cold start.

    Mtdi white smoke

    I haven't build lot of Mtdi's but for track I use 1.5mm plunger lift. 1mm to 1.5mm is where to aim. I think something like 1.3mm- 1.35mm would be optional for street to start with. More timing, more noise but you got more power on the top.

    Dashboard cluster bad connection fooling pump G149?

    I monitored engine readings with vcds! Everything was same when engine behave good or bad except car speed on group 006, weird is that cluster is showing correct speed all the time but vcds is showing 0 km/h when cars starts to act funny.

    Dashboard cluster bad connection fooling pump G149?

    No codes in CVDS. I start to think logically, I would heat up car interior winter to. Today was +5 degrees outside, no problems, but yesterday was +12 on car made funny things. I think I have to to some graph logging with VCDS, it should show up what else jumping up and down... But why...

    Dashboard cluster bad connection fooling pump G149?

    Can dashboard cluster bad connection fooling pump G149? It started in hot weather when car was siting in the sun, it was almost impossible to ride, pump voltage was jumping up and down. When engine warmed up and car interior cooled down everything was fine. I have changed injector pump, pump...

    End of a 12mm pump! WHY?

    Finally made some "science" with plunger springs! I got them from my friend. He thinks they are from VP30... Can someone confirm VP30 spring measurements?

    1.9tdi + P7100 picture.

    I don't know why you need bigger nozzles than 0.360mm. VE pump don't have enough fuel to support even them. 0.360mm nozzle can flow 200cc of fuel up to 7000 rpm on average of 600 bar pump pressure in decent time.

    There isn't problem with big nozzles, you can have it done in any size. There are many ways to make big nozzles. If you increase pump pressure your nozzles are flowing more. Some time ago I made nozzle size calculator to got some understanding of spray time etc. I don't know how or can I upload...

    End of a 12mm pump! WHY?

    But how to avoid this problem or how to make it stronger? Nitriding as they are doing with camshaft? Grinding more material off and weld on some really strong material and machine it?

    End of a 12mm pump! WHY?

    We all have noticed that clear fuel is going in but bubble fuel is coming out of the pump. In some point there are some kind of vacuum on top of the plunger when there are filling time. 12mm head is making bigger vacuum than smaller ones and are pulling more air out of the fuel. Even if pump...

    End of a 12mm pump! WHY?

    What springs did you use? My pump heated fuel quite a lot first 500 km so I didn't push it at that point. I'm using only PD lift pump, but was monitoring pump inside pressure some time.

    End of a 12mm pump! WHY?

    Jeah we have quite bad fuel.... I used 0.240mm nozzles, some engines what are using 12mm head are using to 0.240mm nozzles. (Now I have 0.260 nozzles) I reduced my fuel map something like 30% I thought that factory automatic pump with 11mm plunger, higher cam lift, 0.158 nozzles and higher fuel...

    End of a 12mm pump! WHY?

    Hello! A year and a half ago (25K km) I buildid 12mm pump: In good condition pump New shaft bushes New seals New 12mm bosch head (made in Germany) Strongest springs what I find (TDS I thiks) And now there are lot off metal inside the pump, I thought I have broken spring or bad camplate roller...
