Yes Dennis has come great content and I had a few emails back and fourth with him just this week. You'll notice though that he doesn't use a cyclone on that camvac. All he's done is add a muffler which makes sense as my old dual motor DX4000 is loud AF and the camvas is just that with a port angled on the side rather than straight into one side of the cylinder.
I mean, adding a 100mm cyclone to a camvac is still going to work, and it won't hit your airflow speeds to much because of the size of it and the airflow speeds not being all that high in the first place. You might find though that some fine stuff still ends up in the camvac because it doesn't have enough flow to keep particles moving quickly inside the cyclone and so stick to the side. I'll be interested to see what you find after using it on various tools.
