What are you trying to solve? The OEM pumps are more than sufficient and generally don't fail unless fed dirty oil.

Upgrades can solve many unthought of issues. Now I'm thinking of how exactly the driven slot in the vacuum pump gets worn into a bow tie. It has to be caused by a dwell period of time in suction vs the time the next vane gets to the suction period which relaxes the oil pump shaft causing it to slap backwards against the opposite end of the driving ear in the vacuum pump. Clear as mud ? Maybe there's a better oil pump that solved this issue. Of course, simply having more oil flow wouldn't be bad either.

I have no issue with oil pressure. I'm just looking for a better mousetrap if it exists.

Probably a solution in search of a problem, however I do understand what you mean by the worn drive shaft. But consider how long that lasts.... typically these oil pumps will last "indefinitely", certainly as long as the rest of the engine.
The 1Z's basic design was a leftover from the early '70s anyways, so by the time it came around, it already had the latest and greatest.

I replaced mine at 440,000 miles and while it had some wear, it was due to my neglecting to change the vacuum pump to oil pump shaft seal. Through the design a new seal will keep oil in the mating surface and reduce wear. The oil pumps can be rebuilt as well.

Let's see, run extremely expensive oil pump setup or AC + PS with perfectly fine factory oil pump. Not too much of a tough choice in my book. Besides, you'd have a tough time implementing this on the diesel, with IP you'd need some other custom bracket to support the alternator. And I don't see it but is the water pump absent or is it being driven by the timing belt? This is obviously a setup for Mk1 and my guess it's a Mk4 2.0L?you could do this, but I believe that money is better spent elsewhere.
As OH said, that's a solution in search of a problem.
Based on the position of the oil filter I already hate it.

So..... I found a new Pierburg vacuum pump and much to my surprise, the slot is a bow tie from brand new. Go figure.

Yes, it is a bowtie but it's also easy to see wear.
Here is what it should look like:
And here is what it should not look like:
At the same time, this is what the oil pump keyway should look like:

Please note that my post was an example of sarcasm to point out that this is a solution in search or a problem. I would never seriously suggest a dry sump on a tdi for any reason.

for one the belt is in the wrong position at least once, twice over. if you lose the belt, hence the oil pump, how does engine stop? it ll keep on running, starving. the belt is now also in a very exposed position, not very smart for a belt just as important as the timing belt.
Holy poop, I was being sarcastic!! Sorry if the tone is lost in text. Personally, I think it's silly to replace a pump that works very well as designed.

I wasn't picking at you, you already said that you felt the money was better spent elsewhere.
This has to be a racing setup of some sort. I can't imagine the company that builds it would sell any for street use.
