Afm Mesh Removed

[mid life crisis]

i reckon if the mesh didnt need to be there nissan would not have fitted it in the first place. car companys dont like to spend a extra cent when building cars so it must be there for a reason .personaly i think if anyone reckons there are big gains to be made by removing are kidding themselves

Actually if you look at the orange sticker on the Z32 air flow meter, it says made by: UNISIA JECS Corporation, Made in Japan.

Nissan just buy them in, like many other parts in the car.

I've read the negative boost article and it makes a good point. They measured vacuum before and after the AFM and there was a fair difference, which became a smaller difference with the mesh removed. The manometer doesn't lie.

If there is gains to be had, it would probably only be had if you retuned the ECU to suit it. Next time someone gets their car dyno tuned, try with and without mesh see if it makes a difference.

there was a article in zoom or hpi a few years back about this exact topic, anyone remember it.

i could dig it up if you want?

Yer that auto speed bloke didn't exactly think too much about why the mesh is there.. "to prevent stones should one get through the filter.. lol"

Maybe it's just there so that when grease monkeys are working on the car they don't accidentally shove something in there and f**k it.

lol most likely.

curious..at such a high velocity, compressor spooling and such, do you still expect the flow to be laminar?

maybe closer to the wall...I think can be safely said that the flow is turbulent anyways....what does it matter if the mesh cuts the flow or not..

chances are the mesh are there to prevent larger particles going into the intake system stuffing up the turbo...

better the afm then the turbo..
