Dump Valve

Ive had a Baileys BOV on my 04STI since I bought it (fitted by previous owner),, Im getting a bit sick of the sound and sometimes it opens a bit when your just sitting at 80 on the motorway (spring must be getting weaker) thinking of replacing it with a recirculating one or a new BOV with a stronger spring (Forge??)....... Any recommendations??

Also is there actually any performance benefit to a BOV?

no performance benefit mate imo i had baileys/forge then went back to oem recirc valve car run alot smoother

Go standard !!!

Aye that's what I thought, If he'd given me the OEM one when I bought it id have stuck it straight back on, I'll put a post in the wanted section and see if anyone's got a standard one kicking about, cheers lads

I tried a few mate my car ran shit so went back to standard never run better !!!

Spot on. Standard defo sounds like the way to go then, that's what Andy Forrest recommended when he mapped it as well.

Thanks again matey

Agree, go std bud.

best thing i did fitting oem dv back on was fook on for me as recirc pipe was missing

You will find it idle better, mine was up and down and did not settle right at junctions and stuff.

I've. Replied in the wanted sec I've got a couple

I have ran a forge and now have a HKS without any issues at all, the bailey DV's have notoriously soft springs so can cause idle issues.

Yeah I wouldn't recommend the Baileys like, its just a bit irritating how you can hear it opening when your just crusing at 80 - 90pmh then have to either ram your foot down to shut the fooker or let off then start again. Just agreed to buy an OEM valve off ian (STI04) so that should sort it

i have a baileys on mine, it does the same when im cruising at 80-90mph too

can you not just block them off or do scoobys not like that?
was the first thing i did on my cozzy and on my s14 as i like the noise.

if u have a dv12 (bailey) throw the twat in the bin

Depends what turbos on the car I think

Iv got turbo smart with twin horns never had any trouble just set it to hard

You can block them off but it depends on wat turbo you are running to wether it will do it any harm!

We have a gfb wrx hybrid bov fitted to ours it does both blow off and resircs.its loud but sounds awsome flutters on low revs and Loud under load.no running issues at all with ours.
