clean your airflow meter

[R31Heaven]

I myself would not take the mesh out of you AFM, I could not see there would be that much more air flow from doing so, all I could see happening one day your pod falls of and a big bit of debris going into your turbo (Cringe) the cons out way the benifits. When I cleaned mine I use some electronics cleaner from JayCar the fine mist cleaned it a treat. dont worry about the cleaner going through your inlets as you do it with the engine turned off and electronic cleaner avaperates on contact, you should see the oil and crap that gets sucked in from the breathers that would get you worried...

[Steve]

I used brake cleaner - worked a treat no residue, just quick spray and all the oil/grease etc just disappeared like magic. I have since included this in regular servicing, used it to clean my AAC vavle and have only had good results.

Whilst brake cleaner and other products may not have a

detrimental effect to the performance of your AFM, why not use

electrical contact cleaner - a product that has been specifically

designed and formulated for cleaning electronic components, like

those in you AFM.

At the end of the day, its personal preference. Personally, I'll use

the stuff the boffins use.

Your Skyline would not exist without boffins.

[Steve]

Hmmm, dont think I have ever seen any AFM cleaner?????

[Ait]

Pop down to an electrical/electronics store like Dick Smith's or Tandys and get thyself a can of Electrical Contact Cleaner. Remember not to spray too near the filament, but let it 'mist out'.

removin the rear mesh wont do jack - the front mesh is always gonna

be the bottleneck. leave em both on

[GiJOr33]

bah.... i say pull them off and see if it makes a difference... that is if you can put them back on again!! lol

i don't see the point of having the mesh cos the air filter should have stopped anything getting through. If your air filter "falls off" or stops filtering then you obviously haven't done a proper maintenance routine and checked that there are no tears in the filter and that it doesn't need replacing or tightening.

the mesh is there to stop knuckle heads from poking screwdrivers into the hot wire. It is a restriction and you will increase airflow/hp by removing it.

It is not designed to 'smooth airflow' it is just cheap-ass(uneven and poorly constructed) mesh.

Do yourself a favour after checking your head for knuckles.

[R31Heaven]

By removing it how many Kw will it give you ?????

[teka]

I'm not 100% sure it would depend on different variables (of course) I've heard of up to 11 R wheel kw's!!

Steve-

An AFM is an electronic device. Its sensors are electronic

components.

Hence, electrical contact cleaner. This is just common sense.

Hahah i dont think so

[Steve]

I have found that electrical contact cleaner can be wanting, especially if whatever you are cleaning is really dirty. It is not uncommon for people in the trade to use other than electrical contact cleaner - I have a good friend who does work in the trade, and he uses all sorts of things - including brake cleaner for components that have come in to contact with oil/grease. He also uses erasors for cleaning electrical plugs, as he recons these work best of all.

I am not the only person that uses brake cleaner for AFMs, and I would challenge you to find anybody who has ever damaged their AFM by using it. I am not saying that brake cleaner is your only option, just that it is a viable option that provides good results very quickly and easily - which is the point of the forum. Also I am not saying that electrical contact cleaner is no good, just that there are other options as well - and to each their own.

As for common sense - well I strongly believe that there is no such thing...lol

Steve-

With there being multiple ways to skin your neighbourhood cat,

there are also multiple ways to clean your AFM.

Never did I mention that using anything besides Electrical Contact

Cleaner would damage an AFM. I was simply suggesting to the

more timid and hestitant Skyline owner, that ECC would be a very

sensible choice.

A sensitive output device like an AFM is heavily reliant on its

accuracy, which is why I, personally, would opt for the gentle

decontaminating action of ECC.

This is just my opinion, and I respectfully accept yours.

In this instance, neither of us are incorrect.

As for common sense - well I strongly believe in attaching your

bungee cord before you jump.

[GiJOr33]

you can always run ECC over the AFM till it's clean, brake cleaner will just do it in one go... ECC might take a couple of applications!

[rev210]

from the look of the mesh there may be as much as 3-4kw@motor in the top end by removing both. More if you have a higher output engine than stock (ie: big turbo)

[Steve]

Pickled Icecream, no worries, just sounded to me like you were saying ONLY use electrical contact cleaner, and that people suggesting to do otherwise - should not.

Sorry for the misunderstanding

Hi guys, I use only products that don't leave a residue, so WD40,

RP7 and Carby Cleaner are out. Non residue stuff like EEC or Brake Clean are the go. I have even used straight metho (pinched it off a guy in the Cross one night) when the car wouldn't start.

Hope that helps.

[Sydneykid]

Ooops, almost forgot about the "removing the mesh for increased power" posts. If the restriction of the mesh is the limiting factor in the power chase, then removing it will give a result. But only if all of the other bits, like airfilter, inlet pipework, turbo, camshaft, head, rpm, intercooler etc are being held back by the mesh's airflow restriction. Pretty unlikely in most cases.

Hope that adds to the discussion.

Steve -

No problem. It is quite easy to be misunderstood under

these circumstances.

In relation to the removal of AFM mesh. I recently removed mine

for a number of reasons.

1. Zoom said so. (I also eat Special K to make me look good in

tight jeans and torn red shirts that accentuate my breasts, and

drink CC and coke to make my skull indestructible)

2. I was bored.

3. I can understand how removing the mesh could possibly,

maybe, one day, if you're luck, prove to be beneficial.

4. I performed a stupidly simple test that, through my powers of

super geniusness perception, I already knew the

answer to. Much like knowing that inserting your penis into a

toaster whilst making your morning meal may cause erection

defects.

Test - Once having removed AFM, use your mouth to blow

through the meshed AFM with your hand on the other side, so

you can feel the goodness. Then, keeping the distance from your

mouth to your "sensor" hand constant, remove the AFM from the

equation and blow directly onto your hand with identical force.

In that particular instance, the meshed AFM caused a restriction.

BUT...

When I think of the velocity and quantity of the exhaust gases

that those six pistons are pushing out through the exhaust

turbine to spin that shaft - It reminds me of my foot, and an ant.

In short - I am sceptical, but what the hell! It kept me away from

pornography for 20 minutes and reduced the Skyline's total mass

by 10 grams.
