Acoustic valve...

[AstoN]

I know this has been discussed couple times, but i need to know how the acoustic valve goes back onto the car, pictures would be ideal.

Car has been repaired but came back with couple bits not on propperly as per.

So yer, acoustic valve, pictures of how it should be, possibly without headlight to be more specific, and how the horn should be as well, needs to be right, you know this.

And for those thinking it, yes this is a fresh edit of my previous thread where i named the wrong part, sorry.

You haven't got an acoustic valve on a dCi afaik? Ph2 172-> only.

 

[AstoN]

It's for an 02 172, forgot to mention that.

I also don't know what afaik means....

afaik = as far as i know..
take off the LHS wheel.
remove inner plastic guard..
unbolt the acoustic valve
plug up vacume hole.
disconect the electrical section from the bracket...
and reconnect the electrical bit and place some where..
put acoustic valve some where safe..

I need to put it back on propperly, not take it off.

Thanks.

How does the acoustic valve work?

I mean, does it shut when there is vaccuum in the plenum chamber or does it open?

If it shuts when it "sees" vaccuum then could you just clamp the vacuum hose with something so that it sever sees a vaccuum and therefore never shuts?

I know it sounds lazy but it might be an interesting way of doing a quick comparison on a dyno.

It's shut at cold from memory, to keep induction noise down. It opens once warmed up.

I think

Im not so sure, I followed the 8mm thick pipe from the valve to the plenum chamber - that can only mean vaccuum

They definately run a bit funny when they are cold tho but I dont think thats related to the poostick valve

Yeah I think they run rich when they are cold - mine stinks of fuel when I start it in the morning. If youve got a mental exhaust then a rich mixture will make it pop rather a lot!
