1990 5.0.. anyone put a BBK CAI on (oval filter) with BBK MAF.. and notice you have to turn the MAF housing so the sensor is in the 3 o’clock position rather than “12” (top)

Would rotating the filter itself change the air flow coming into the tube ?

Sensor up, car bogs down at 3500 rpm when you punch it. Sensor at 3 o’clock it’s a beast

I doubt rotating the filter would change anything. It’s probably the bend in the tubing creating the need to put the maf in a particular position. Turbulence happens when the air takes the turn. So, at the maf location, air flow can be different on each side of the tube. So, rotating the maf housing puts the sensor where it more accurately measures air volume to coincide with given amount of fuel delivery.

Dump CAI then. Sily having to turn the housing like that. Stretch the crap out of the harness unless to separate it from the rest of the wires it’s packed with. And makes the build look... less clean.

I’ll grab a different CAI

Any recomendations ?

Stock airbox and tubing with KN filter. Some people remove the air silencer from the fender well side but benefits are debatable.

How close is your maf to the bend?
Maybe a pic?

I think your maf is too close to the bend, I'd see if I could swap the hard pipes, use the short one between the maf and the tb.

Had it that way the first time and realized I had them backwards.

Think I’ll just get a new CAI

Or Toss the stock one on with this MAF and see what happens

What is that? I can not hear you above my whistling BBK throttle body.
When I first installed it, I turned my BBK MAF to where others had said it ran best and have been very happy with it there. The PO had already put the Fender well CAI on it, so I left it on and adjusted it for clearances.
I do not have the large difference in diameter between the pipe and MAF like your pictures. It looks like those rubber adaptors shrinking and opening up could be creating turbulence.

Find yourself a screen to fit into this fitting between the pipe ends:

Let us know if @Noobz347 ’s idea idea fixes or changes it. The original meters have a screen, so he might be a genius.

Yes he is.... This makes an easy fix for maf turbulence especially with blow thru turbo apps.
Your application is a good candidate as well.

This looks like a good product, and it was just at the top of the search.
