laust manifold's home-made look.
Can you run a CNC machine, or better yet, do you have one in your garage?

Don't take it out of context. or make more of it than intended.
No insult intended. Apologies - laust.
This seems a cleaner aproach to me - and I would prefer over the unorthodox shape of laust manifold.
Nothing more, nothing less.

It should, remember - this thing is still in the R&D stage - everything's subject to change. Hopefully I will be able to install a prototype into the 951 soon and try it out for real.......

I have read very quickly through this thread and if my Vacuum Manifold can be re-designed for easier manufacturing without compromising its function, then more power to it and in that case I certainly wouldn’t mind my name associated with it.
Dan, it looks like a good idea and just a few quick comments to what I see:
1. Make sure the cross-sectional area for the flow is decreasing toward the hoses or kept close to constant.
2. Make sure the ports will work on both the silicone hoses and the rubber connectors to the hard plastic hoses.
3. Move the ports as close together as possible so the worst case of the silicone hose solution or the rubber connectors to the hard plastic hoses barely touch.
4. Make 4-, 5-, and 6-port versions, with the 4-port version being shorter than the other two.
5. With those (black) ports installed it looks as if the VM cannot be screwed in or out. My solution would be to make a long banjo bolt, drilled, cross-drilled and turned down, so condition 1 is met.
6. Make sure only metric tools are needed for installation and removal.
With those suggestions I may have moved some of the manufacturing convenience to user convenience.

(If anyone wants to trade a laust version for a sharkey version, lmk )

from my experience I can only reccoment NOT to use such a manifould for all the vac lines. I would rather suggest the complete opposite. Reason for that is quite simple: There are a few "consumers" of vac and a few componets that only need the vac (or better mani pressure) as a signal. The biggest "consumer" is certainly the wastegate supply with its own line but also the recirculation valve needs vac flow due to its piston volume. Components like fuel pressure regulator, boost pressure sensor in the DMA/KLR... need only very little vac flow and use vac only as a signal. What happens when you connect all compnents that need vac to only one fitting is that locally, just in the fitting the vac pressure does not anymore corrospond to the mani pressure which it should do all the time. Reason for that is that due to the temporary high demand for vac flow during load changes the fitting is a restriction and as a result there is a difference in pressure in the signal lines compared to the manifould. DME/KLR receive wrong pressure data and fuel pressure is wrong as well. Certainly only for a small time under transient conditions but in my eyes a vac manifould sonds like a bad idea. This statement is a result of my own practial experience so far.
