Do Shrouds enhance air intakes?!

If I put a shock intake into a shroud should it pull in more air or benefit in any way?! I have a lot of parts count I added from my shock cones not quite being good enough 1:1 with rapiers. Could I add a few nosecones and improve the intake. Or does anything more interesting happen to thrust with rapiers as they are supposed to increase thrust with intake etc. does it get to speed faster. I'm not sure how to test this.

 

besides the fact that the thing behind the shroud seems to get horrible drag and isn't counted as having a cone despite a cone being present...

A shroud is a different thing than a fairing. I assume you mean a fairing.

I have no idea what would happen if you put an air intake inside a fairing. If it still sucks in air at all, then that could easily reduce the drag of the intake, and increase its heat tolerance. You should test it once and find out. It would be easy to test on the runway or launchpad -- you don't even have to get into the air.

I mean a shroud. I think they are supposed to pull in more air for propellers. Do they do this for air intakes.

 

Also seems to have a massive drag problem with whatever object is directly behind the shourd. It's like it's not counting the node as being covered.

Shrouds cover engines before engines are staged. They are almost purely decorative and do nothing except slightly change the drag of the engine they are covering.

I mean the new shroud that you put propeller engines in. I think it's called a shroud also. They are supposed to improve propeller engines.

It's called an S-12 Fan Shroud.

I put a picture of it in the Imgur link in the OP.

My guess is: no. But I haven't actually tested it.

KSP doesn't really simulate airflow, it just applies forces to parts that move through a region of space that has the property "there is air here". One effect is that the lift on one piece of wing is not affected by other wing parts in front of it. I don't know how exactly the ducted-fan shrouds work, but I think that without some code that explicitly implements interaction between them and air intakes there just will be no interaction.

I thought(was hoping) maybe it had a check for increased airflow and maybe gave it a better value because of where the node was attached... Of course the propellers air is attached via a second node and not the first attachement... I wonder if there is a way to test that to find out which parts work and how. I wonder if it only works with normal propeller parts as opposed to wings.

Also, there is a bug that doesn't use the Fan Shroud as a cap for the previous part despite all nodes being filled so the part behind it gets massive lag... Unless that is on purpose.
