Cool. One thing I don't seem to hear with this truck is anything turbo related. I have had two mildly modified supercharged GM 3800 W-Bodies and the S/C whine under full throttle was addictive, especially after installing the CAI, nevermind the acceleration
IIRC the custom turbo intake you designed replaces Air Inlet - Ford (KB3Z-9C675-A)
Yes, mine is much higher flow. The factory one is still straight through though, it’s just smaller. No baffles or anything.IIRC the custom turbo intake you designed replaces Air Inlet - Ford (KB3Z-9C675-A)
I believe yours is a little more free flowing.
The factory part looks odd if you think of air tumbling through it.
Wow nice analysis. I suspected some mod to airflow much like some older intakes on non-turbo cars from the 90's had - sort of an appendix-looking attachment to quiet the intake noise.@Racket - I’ve installed the intake elbow I ordered from Revolution and can provide some of the detail you seek. I can confirm that there is significant noise abatement built into the factory inlet elbow. As Mishimoto noted in their blog for the intercooler pipe development for the Ranger, there is a portion of the inlet elbow lined with a very fine composite mesh screen with a white packing material behind it. I used to assume this was a filter for the valve cover breather and the high pressure fuel vapors to have their gases pass through, but now having removed and studied the elbow I see this is not the case. The ports for both the valve cover breather and high pressure fuel vapors dump directly into the airflow path with the fine mesh portion of the elbow being completely unrelated. The portion of the elbow with fine mesh on the inner wall of the elbow is related to this protruded area in the elbow outer wall mounding. I am fully convinced this is a resonator that is designed not to impede flow , but deaden the intake noise whistle for NVH purposes (think similar to how a non-louvered, perforated core glass pack muffler works). The Revolution elbow produces significantly more turbo intake whistle when at part throttle than the factory part.
.
Using a digital caliper, the inlet of the factory elbow is 2.6 in. The outlet of the factory elbow into the turbo inlet is 2.25in. The inlet of the Revolution elbow is 3.35in. The outlet of the Revolution elbow into the turbo inlet via the supplied silicone elbow is 2.5in. Since my K&N Series 63 intake elbow reduces to 2.6 in to match the inlet diameter of the factory elbow, I am reworking the intake to use a 3.5 in silicone elbow to take full advantage of all the extra airflow the larger Revolution turbo inlet elbow can provide.
Sweet! Just so you know that fine mesh white stuff is not on all factory inlets. The design is different throughout the years. My 21 does not have mesh inside the ports. It is a little louder though isn’t it?@Racket - I’ve installed the intake elbow I ordered from Revolution and can provide some of the detail you seek.

If you engineer a bigger elbow to your intake mod (compare notes?) for otherwise stock setups you'd have a really great accompaniment to upgraded intercoolers and charge pipes.
Working on a 4” open intake soon.
Not sure if this was mentioned, but how can someone buy the turbo elbow in the picture above? Loweredon33’s, is this a one off piece or does someone make it and sell them?Yes, mine is much higher flow. The factory one is still straight through though, it’s just smaller. No baffles or anything.
They are done in production batches. We made them in house and will consider making another run if interest is high enough again.
That would so be me!
Sounds good, well count me in if you do another batch.
Been thinking of this lately. Has there been many inquiries?
Some, I’ve been getting more requests for the inlet pipe lately too.
With the plethora of intercooler charge pipes and intercoolers it would make a nice set.
