andyb5 Posted January 10, 2013 Report Share Posted January 10, 2013 ME7 is a 3" OD MAF, not 3" ID like the A8 one Hussein is using Link to comment Share on other sites More sharing options...
Über855R Posted January 10, 2013 Author Report Share Posted January 10, 2013 Did a little more searching and found a company that makes honeycomb for this purpose. Also found some corvette guys on a forum that said no honeycomb is very bad for MAF readings. It might even help to add extra honeycomb to our MAF's even without an upgrade just to straighten out the air flow. Here is the link. And they will cut custom diameters. @Zappo, from what I was reading this small change might help a bit at high rpm with the weird erratic figures up top. Some people on the vette forum said it did for them. Link to comment Share on other sites More sharing options...
andyb5 Posted January 10, 2013 Report Share Posted January 10, 2013 From what I understand, the mesh is to help ensure laminar airflow past the sensor element. Removing it gets rid of a minor flow restriction, but the turbulent air makes readings inconsistent Link to comment Share on other sites More sharing options...

Some people on the vette forum said it did for them. Well, as I have said, Lucky has discovered the stock MAF even maxes out on the stock engine and turbo. Everything after it maxes is a guess, but he said that Volvo guesses very well I have no doubt it would help my top end and it has always been in the plan to swap it out. The only thing that has really held me back is how much work I would need to do just to get the car to run correctly at idle and normal driving.

JVC Posted January 10, 2013 Report Share Posted January 10, 2013 Why not tune for speed density instead? Link to comment Share on other sites More sharing options...
Zappo Posted January 10, 2013 Report Share Posted January 10, 2013 That is stand alone and we have discussed earlier why we can't do that. Link to comment Share on other sites More sharing options...

I don't blame you, starting over on your tune wouldn't be worth it. You probably have enough power to get where you need to go. Didn't you say you need to turn the boost down in autox to be competitive? Traction is a problem for these cars lets be honest. Actually I meant just add honeycomb.Found some corvette guys on a forum that said no honeycomb is very bad for MAF readings. It might even help to add extra honeycomb to our MAF's even without an upgrade just to straighten out the air flow. Here is the link. Forgot the link.http://www.saxonpc.com/100mm-cells-for-100.html They said in the linked^2 thread there should be a 10:1 ratio of (hole size):(honeycomb depth) in ideal situations to minimize turbulence. Realistically with a stock MAF you could maybe put 5:1 or 6:1 depth inside and with a small trade off in restriction get much better readings. Just a theory but I would be interested if someone with appropriate equipment could try this and measure the difference in MAF signal, it might be surprising. Maybe not after 5k when it stops reading anyway. But <5k, where most of us live and drive primarily. Link to comment Share on other sites More sharing options...
