1.23"
I'll be back at the shop Monday and can measure one to let you know. Or if you have it there with you just measure the diameter of the round part where the oring is.
Looks like scottryana got it.

Ok, sensor and 3.5" MAF pipe ordered!
Get the air straightener too. For anything over a 3" housing I highly recommend running a straightener before the maf sensor.

Yep, got that too.
looking forward to this.
these sensors don't like turbulence so being close to the filter can cause issues.

I don't think there is a safe place to put the sensor then!
The only options are right after the filter, right before the turbo inlet, or between the intercooler and throttle body.

? New housing and sensor looks like it should be able to go where you stock MAF Housing is, you might have to shorten your 4" intake tube and use a silicon reducer. But looks like it will work fine. The air straightener just going inside the tube. It helps even the air flow out so that a bunch of air doesn't rush under the MAF sensor creating an unbalanced reading.

Yep that's what I'm planning on. Got a new 3.5" filter, then the honeycomb, then the 3.5" MAF pipe, then 3.5" to 4" coupler to the intake pipe.
Cool, I am doing about the same, but will be just using a 3.5" for the entire distance from turbo to filter. Not sure which filters you use, but I have had really good luck with "green filters" I will be using 2459.

I know you said you won't really be going off road much, but on my last truck I also ran an Outerwear prefilter and it saved a lot of dust from the filter.

I didn't see any directional arrow on the pipe, You want to orientate the pipe so the connector on the MAF is the same as the stock one.

Parts are in. Will report on results later tonight.

Ok problem solved with new maf setup.
Here is a wot 1st gear pull. You can see the maf values peak at max boost then slowly slope downward after the peak torque. The afr is still too lean for me even in the lowest gear/load (high 11s low to mid 12s). 450cc injectors will be here on Tuesday and at the power level I think they are required.
No changes were made to the current fueling with the new maf. Long term fuel trims after a 15 minute drive were at 20.

Glad to hear that fixed it.

The footprint was nearly identical to the stock maf. No cutting needed.
The honeycomb fit tightly into the maf pipe. Even without epoxy I don't think it will ever move. I had fears about it getting sucked into the turbo, but that thing is in there snug.

glad to see your progress and homework. This is exactly why i went with a "bolt on" supercharger, because i didn't have the time or the brain power to work all this out for a turbo, even though that's where my heart was.
