This update is something beyond the ordinary.
Now the pump is modified into a monster just for this engine.
You can read what is done and see a clip of the test run on the flow bench.
Many thanks to Göran "diesel mech" Lindgren.

OK, then it was time for the 2nd upgrade of the pump, Edition R
Do not miss the movie clip I have made for the sake of you readers, further down the topic.
The following was the first performance upgrade.
Replacing rotors 80-10 mm
Change the direction from right to left using wire EDM, among other things ;-)
Then the pump is delivering about 230% more fuel than stock, ended up on about 80 cc of fuel.
Edition R is reworked like this:
Modified RPM controller weights, it was not enough speed first round, now it will be sufficient.
LDA, cover with specially sharpened stick to get more fuel at full turbo boost pressure and eliminate smoke in large quantities, it will probably smoke a bit anyway, but not as bloody as before
Regulator Spring, changed from a separate idle spring into an integrated spring-in controller package (VAG 2.4 d)
Modified controller bridge for longer travel of LDA = more fuel around 100cc @ 1500 rpm
Test run of the bench and shot.
