Dump/ Recirc/ Blow Off (Confused)

Discussion in 'All Things Technical' started by ChrisValentine, Apr 30, 2015.

  1. So, I want something to make my 98 Subaru Turbo make this sort of sound
    https://www.youtube....h?v=QBUIsYa_E5M <--- More like this one. Is that just with a Forge Valve and filter?

    OR do you have any videos of yours that sound better?

    I've just got a Cosworth Panel Filter and Scorpion centre and Backbox. Would I need to get it mapped when I put the Forge Valve (or any valve on)?

    Does it badly affect petrol usage?

    Any negative affects on the engine or turbo? (read up and found quite a bit of scaremongering... )

    Thanks in Advance,

    An hks ssqv will be just what you are after, and look really smart in the engine bay as well. No re-map required either

    Beg to differ I run the HKS SSQV 3 and does not sound like that. would depend on the amount of air dumped to pressure produced as the burble you hear is the sound of the turbo blades bouncing the valve you need big turbo and small dumpvalve so you get the chatter. HKS SSQV 3 just dumps with a wooosh no chatter

    I went for the Forge VTA (HKS was out of my price range). Should be turning up the next few days, so I'll let you know :)
