Moving The Afm

[bizket205dimma 0]

i whant to move the afm on my 205 tt gti to the bulk head behind the engine will the extra heat affect the afm or would it be ok?

any help

thanks in advance

Don't think extra heat would do it much good

 

Also extra heat into your air passing threw the AFM is not ideal

 

Needs to be kept as flat as possible too in its new position

agreed.

Not true, they work at any angle, if they were sensitive to gravity you wouldn't be able to drive up and down hills without the fueling going haywire. I'm not sure why this is repeated so often.

what ime gonna do is put a heat sheeld above the turbo and the afm will have a cold air feed from the front of the car into a bmc d.i.a. air filter

LOL,not talking about the slight difference if say you go up and down hill!!

 

But if you put them on there side,or any any angle like that gravity starts to take affect on the flap,so it will make a difference

 

As the flap is meant to moved by the airflow,so having it on too much of an angle with gravity affecting the flap will either make the flap harder to open,or drop open too easily.

 

Agreed????????

disagreed, think of how the AFM sits as standard in a 205...

[Ryan 99]

The spring tension in them is quite strong. Compared to that gravity is only going to have the slightest effect, if it's even noticeable at all.

For that to occur the AFM would have to be very worn and I suspect would show other symptoms too.

I used to think that they needed to be mounted flat to the horizontal, but that's because I naively trusted the more experienced members on here Anyone remember the AFM Police?

 

Yes, in truth, gravity will have an effect on the flap if it is operating in anything other than the horizontal plane (i.e. the flap spindle being vertical). But since it is a sprung flap, with a fair amount of resistance, the effect that gravity has on the flap will surely be insignificant.

what i plan on is a 90 degre pipe from the turbo to the afm wich will be flat then anouther 90 pipe from the afm to the air box (bmc dia) where the afm was

and a pipe from the air box to 1 of the moretts.

oh how do i convert my moretts to work as dip and full beam in 1 light?

what would be a far better idea is to remove the AFM totally and use aftermarket management

 

 

or 406 turbo management even, cheaper way to do it, and still mappable.

Each to there own I suppose

I'll stick with the advice given to me by a long term pug tuner who says he has seen the affects of using AFM's on there side

Thats fine and if your long term pug tuner wants to come on here and argue this then that is also fine.

 

However we have specific rules about posting second hand information...

 

- when it comes to technical information and guideance, think twice before you hit

the "submit" button - make sure that information and knowledge you are about to

share is either first hand or verified fact. hear-say and deliberate missinformation

will not be tolerated.

 

...which basically means don't post something when the only way you can back it up is to say you heard it from someone else.

Got to agree with the above, It makes no differance what angle the AFM is, Even some Induction kit's have them on there side for example

[Luca 1]

Guys the AFM will work at any angle. I've currently got mine on a 45 for a cold air set up.

 

Moving it to above the exhaust manifold would not be a good idea as per all logical arguements you can think of.

So if I have been told something by a professional car tuner/pug expert that could help another forum user I am not allowed to post that info?????

 

Thats the most stupid rule I have ever seen on a forum and makes no sense at all.

 

I will stick to what my tuner said cause my car was running spot on when he tuned/set it up.

 

Or should I not believe him cause a few users on here say its wrong?????

Given that dozens of users here, including myself have run their AFMs at all different angles for many years without problems, then yes, I'd say he was wrong. Just because he's a "tuner" doesn't make him infallible.

[Cameron 16]

Sorry, but I put an AFM on it's side once (so the flap would be opening upwards) and it made the car incredibly sluggish and bog down at low revs. When I rotated the AFM back to it's proper position it worked perfectly. So before we all go slating that bloke for suggesting that they are position sensitive let's make sure we know what we're talking about.

[welshpug 1,677]

they're only position sensitive if they're knackererd

Your right,doesn't make him infallible,but dozens of users on here or someone that tunes Pugs all week/year/for years,let me think whos advice will I take

 

Didn't take long to decide

[Ryan 99]

The collective wisdom of dozens of people, or the opinion of one? Didn't take me long either.

I never really noticed the difference of moving the AFM from standard position, to that used on a K&N induction kit.

Only problem was the plastic cover kept coming off, due to previous owner having it retracked or something along the lines.

 

The car being renovated by JustGTI's sent a shiver down my spine, when I realised what was writen on the plates I thought O F*ck and the amount of problems which entailed after

You didn't think it was worth trying another AFM?

[Rom 0]

I ran for a while with mine on its side with no problems.

 

I now run with it flat. Because i can just about wedge it in flat, so why not. Anything i can do to help cant hurt ?

If i couldnt fit it flat, id run with it on its side still. As i noticed no differance either way.

 

If the AFM is knackered enough to allow gravity to effect it that badly, im pretty sure youd notice other signs.

 

So called 'tuning gurus' are not gods of knowledge. No one knows everything. There are plenty of people on here who 'think' they know best. And plenty who 'do' know best.

Ive learnt not to take the word of any one person too whole heartedly. I doubt many if any people set out to mis inform you, but it happens.

If theres a large number of people on here saying something, id be pretty confident its correct. As between us all, there is a wealth of knowledge.
