Can I - nah, I am going to - make a suggestion.

How about a sticky that says "NEW TO THE FORUM? - PLEASE READ THIS !!!!" and then explain that a lot of new members initially ask questions or for help. In that case use the search facility eg. if you have a question about Dump valves enter dump valve in the search box.

This will prevent the forum possibly being wrongly regarded as a bunch of Subaru supremacists rather than ordinary people who enjoy banter but who are also VERY well informed.

PS - do I have to put a naughty word in so that this post gets Mods' attention ?

On a serious note please don't attack me as per the o.p do dump valves carry any advantage over standard NOT getting one before I also get attacked!! Can't stand them just wondered...

Yep, that's the (top) one.

So, it's obviously not effective, despite the best will in the world.
Perhaps a word or two in the registration/welcome email might help ???

Eg. "If you are joining to initially seek help or advice please look at this sticky first: https://www.scoobynet.com/scoobynet-general-1/853505-please-read-before-posting-threads-requesting-help-advice.html "

I don't think this is the thread to post this, but.....in the interest of science I bought a genuine HKS DV from someone one here and fitted it to my car this afternoon. I can confirm that this particular dump valve did not present me with any idling problems, any fuel correction issues, any boost issues nor any richer fuel values read from my LC-1 when lifting off the throttle. All confirmed via datalogging. Driving around town normally doesn't produce any blow off noise either.

I'm not sure if I'll keep it on, I just wanted to confirm something for myself........

I have an ssqv3 that was running recirc, when I changed to a front mount it was briefly running vta as I didn't have the pipe to run it to the inlet and it didn't effect the running at all either just made an annoying noise.
running dv less now though. :thumb:

I think the issue is the cheaper dvs are not held close by vacuum like the hks and can leak.

either way I don't like the noise.

Mmmm.........
Given that the art of effective communication is to convey a message to those who are 'not in the know', I class myself in that (latter) category.
I therefore am not ashamed to ask what that statement/post means ?

I'll even admit to 'only' having a Grade 1 'O' Level English Language and also having possessing a GCE 'Use of English' certificate.

For the likes of me, please can you enlighten us master?

if you are familiar with the standard set up of a Subaru dump valve in standard form you will see it has a pipe attached to the underneath. I am not.
this is where an oem one dumps the air, it recirculates it into the inlet hence the name recirc dump valve.
when you run a vta or vent to atmosphere dump valve you block off this pipe which may or may not cause running issues (not in my case). then the excess air dumps into the atmosphere creating the whoosh sound.
Thank you - I now know that vta' means "vent to atmosphere".
the dump valve on a standard impreza is mounted on the intercooler, obviously this is removed when fitting a front mounted intercooler so you have no location for a dump valve.
Clearly that's the standard Impreza's TMIC (I'm learning the jargon).
the solution to this is a fitting that fits in the pipe work of the front mount, but the location causes issues in attaching the recirculation pipe, so while I had a pipe made up my car was running a vta dump valve.
It goes without saying that it fits, by virtue of being a 'fitting'.
I have now converted to running dump valve less (dvless) which involves blocking of the dumpvalve fitting hole and inlet hole.
Is this is in the original ('standard') now non-existent TMIC/pipework or the modified pipeword for the FMIC (I'm learning quickly) ?

any closer to understanding?

Shame on you lot caning the new guy , this sort of **** makes me want to leave , he asks a simple question . Answer him and move on or don't answer if you are such a clued up member . Scooch if you want one get one your car will not explode or die , it runs slightly different but with everyday driving you would get use to it , if you don't like it after all just take it off and put old one back on
