I can't honestly say I have ever seen this application before (automotive). But they are commonplace in large flow/volume vacuum systems. No, not Electrolux. Kinney and Roots systems places them in all elbows to increase efficiency and reduce drag for pumpdown times on large semi-conductor process chambers.
I recognize the need for taking any restrictions out of the way, but it looks to me as though the inside diameter of that elbow is ~ 3.5". Area~9.6 in sq. The cross section of the pieces removed (at a guess)
looks to be .064" thickness by 3.4" (times 2). .4352 in sq. about 5% of the total area. A restriction to be sure.
But does it overcome the gains that the baffles provide by steering the air in a more even pattern?
I don't know. I would like to see all of these surfaces polished. It did wonders for the aircraft industry.
Looking back, it seems like a few other members recognize them for what they are and what they do.
It looks like my trying to help is causing more problems than solving.
I suppose can just read...

Re: Gutted Intake Elbow!!
Anthony, I'm with Voyager being apologetic for any ruckus caused by my inquiry as to "what exactly you guys were doing with the OEM intake" ! TVT makes a great contribution to this forum and to Crossfire owners in general. Keep up the good work !
With that said, there are experts from many walks of life who frequent this forum, many of whom such as yourself spend personal time and effort in research and development. What better place than to have such a discussion ? As you said we are all adults here and so far the discussion has remained reasonably civil. But I agree with Timelord, would it be possible to show before and after dynomomic results concerning the removal of the fins in question. I think we are all striving for the same golden fleece here !

I have no doubt this mod will make more power on top end, but can affect low end performance and maybe even way down low at idle. It is a fairly inexpensive mod that you can easily buy a second one to switch back and forth from - I think most of us will never see the track but for those who do, I'm sure any change in driveability will be worth it especially if you are a track regular

Re: Gutted Intake Elbow!!
I took the time and effort to do this on my coupe.. Didn't do it on the wife's roadster.. I'm "sure" there is a difference.. (less restriction is always better) .. but there was no performance difference that made me think "take hers apart and do it"...
Re: Gutted Intake Elbow!!
They were probably put there to get a smooth flow of air round the bend and cut down turbulence, if so their removal may in fact affect performance negatively.
They were put there for a reason obviously.
I think mods to the NA affect the performance minimally, I did them. When I could I got an SRT, it has more than enough performance for me as it is. You get to notice the extra nominal 112 hp, adding 20 to 30 hp to the NA is hardly noticeable.

Oh how we forget so easily. I remember a new member back in 2009, when he suggested opening up the intake, and was repeatedly flamed. I also remember when a member chimed in and discovered a few HP and TQ numbers associated ( https://www.crossfireforum.org/forum...-2-m112-2.html , post 30 ) in the MAF descreening and elbow 'baffle' removal, that was offered as a question by that new member. Yes, that new member was me. Yes, a confirmed performance improvement did validate freeing up the N/A intake restrictions resulted in a slight measurable improvement. Every little bit helps, right?
Going to look for that post, hope I can find it (to reference here). Found AND updated.

I would never take out the screen though as it is there and might stop a nut disappearing into the engine.
If it can happen then it will happen to someone sometime.
Same reason I would not use one of these new SC pulleys as they all will break sometime, as even the OEM ones will someday.
