In theory it is meant to, as it release any pressure built up, so that the turbo keeps spinning.
You probably won't notice any difference, apart from the noise.
On the upside though it makes the car pop and bang, and also whoosh.

and if its a VTA it also makes the car run like a bag of **** stick with the OE one

no real diference at all the standard one does the same job without the noise its personal taste unless you have silly power then you may find they do the job they are made for hope this helps i cant say i dont like some out there i have an HKS SSQV

i have a turbosmart d.v same as you and and in regards to the running mine has seen no problems at all although it does get in the way of the double breather rail on the I/C so it's coming off, probably bung the standard one back on for now

I bought my sti7 jdm with one already installed. Been meaning to get it replaced to the original recirc or better. Anyone have any idea where I can get them from and how easy to install?

Which one gets you to 100 the quickest? not bothered about the noise.

appreciate all your views on this thread guys,personaly i do like the sound of a vta,but if it means that the car wont run as good,loose boost/fuel then think the oem is better off..

noob question. i dont have a scoob yet. These things easy to replace /chop and change?

No, unfortunately the engine needs to be removed and all oil drained & replaced to change a dump valve, you're probably looking at about £180-£250 at an independant specialist.

That's one way of putting someone off fitting one!

I always thought it was a bit of a gimmick, "look at me I have a turbo" vrrrrrrmtshhhhhh.


But I can see the whole engine rebuild having to be done in the long run of some of these dv's.

this is a wind up.

the DV is pretty straight forward to change only a couple of bolts and a couple of clips to remove

the only thing that makes it a little tricky is the intercooler may need removing to allow better access.

It certanily made the job a lot easyier on my STi but that has got the slightly bigger IC.

at most a garage should charge an hours labour

At last someone who can use the search option. The best DV is the one Subaru fitted. As for air filters leave the standard air box on with a good filter fitted.

Cheers mate
Most of the mods came with the car, including the wheels, but I'm starting to put my own stamp on it.
