Default Ecoboost, twirly things in the intake pipes

Who has taken them out?

Any get any reasons from someone who knows what they are there for?

I've been messing around with the intake track and the Roush intake. I took those little things out that twirl the air and the noise I was hearing didn't happen near as much. The noise for those that haven't read it before is like the wastegate/bypass valve slamming shut, and you can feel it through the whole truck. It still made the noise a couple time so I ended up pulling it back off and switching to a K&N filter in stock air box......but I left the little plastic twirly things out. All I can tell is the turbos are louder and maybe boost comes up faster (feels like it, no way of measuring it).

Anyone know what they are for?

Found something on another internet forum, not sure what their source is:

They actually designed in some vortex generators in the inlet ducting to help the turbos. I wouldn't take these out, no matter what your drunk cousin says is a flow restriction. Max boost by 1500 RPM is no cake walk and these parts help. If you look closely, you see those lines halfway down the blade? That's some F1 work right there. Optimizing aerodynamic flow to help boundary layer separation. Bottom-line: There's tons of work that has gone in to make these trucks perform.

Ford engineers probably put them there for a reason so I wouldn't touch them.

Not referring to OP but there seem to be a lot of armchair powertrain engineers on the internet. I have faith in the people that are paid to design these engines.

I am the OP, and I agree with you to some extent, but they are "engineering" for a lot of things, some, which I may be willing to give up for improved performance!

Even if the answer is, you take them out, you will blow up, I hope to better understand what they are doing in there and understand how they work. I want to understand what they do and how they work! It is in my nature as an Engineer, also, I know how things are designed, just because we are engineers and design something doesn't mean there isn't a better way to do it.

For all we know they could be for sound only! From the little reading I have found on them it appears that is not the case and I might be better off putting them back in. All I know is that when I took them out the turbo whistled more and the "noise" that I was hearing went down in occurrences. I have seen no ill effects of taking them out for the 20 miles I have driven.

If you don't challenge things how will you ever learn new things?

Those put a reverse twist on the air entering the turbo (which is putting a gentle spin on the air entering the turbo just by proximity) allowing for the turbos to grab more air and be more efficient. This last second spin makes higher pressure air in the turbo, which is most likely the sound you are hearing. Hearing the wastegate is a good sign, it means you have reached max boost.

Cliff notes:
They spin the air.
They are good.
Leave em in.

I will put them back in. Easy enough to do!
