The inside diameter of the MAF.how would i determine this? it bolted in fine. what does the 3" refer too? rock auto confirmed the part number for me

The inside diameter of the MAF.
na don't have that issue, fits perfect. ty thoughYou must be registered for see images attach
Someone had put a 3" on either my brothers Suburban or Tahoe before he bought it. I later caught it while tuning the truck.
Ok, so the formula for MAF sensor should report numerically the engine displacement in grams/second for every 500 RPM of engine speed, "roughly."REALLY appreciate that.
appreciate this . will look at it as soon as i canOk, so the formula for MAF sensor should report numerically the engine displacement in grams/second for every 500 RPM of engine speed, "roughly."
Example: a 5.7L engine should be seeing at 1,000 rpm: 5.7x2 = 11.4 grams/second reported by the MAF sensor. The "2" is because there are (two) 500s in 1,000.
I was messing around with my generic scanner and here are of the numbers I was getting. In my case, the scanner reads lb/min. The conversion factor is to multiply 7.60 to get to grams/second.
In my example, at 1,000 rpm I got 1.39 lb/min.
So: 1.39x7.60 = 10.6, close. 2,000 and 3,000 rpm values are similar.
If your scanner reads gr/sec, then it's easy enough to hold your RPM at 1000 and double your displacement: it should say 7.4x2=14.8. Say 15 gr/sec.
It follows that there should be a linear increase in values with increase in RPM.
I hope this helps.
