    Hmmm... I just did the following :

    - I disconnected the output pipe (bottom) of my Forge DV007P from the hose.
    - Sealed that (air-intake/MAF) hose with a cork and a clip

    So now my 007 is actually operating in fully atmospheric mode.

    NO fault codes or engine lights yet ?!? (I have the AUQ engine btw.)
    (don't even care, because I have VAG-Com to reset them if needed).

    And it gives a truly awesome woosh-sound !! (More a 'POOOOOF')
    Car performs normally.

    It's easy to change te setup once in a while, by simply reconnecting the 007
    to the hose. Or I could even make a T-piece with a tap in it (!), to change between
    atmospheric and recirc "mode" ...

    So guess I won't even need my Split-R. (anyone interested ??)

    Today I am going to route a hose from the 007 output to the grille,
    and experiment a little with some different sized caps at it's output, to get the nicest sound :eek:)

    So it DOES appear to BE possible to have a fully atmospheric blow off valve on a 20VT ...

    Anyway , What's the worst that could happen ?
    Some fault codes, or maybe a slightly little lower petrol mileage ?

    Dont do it man, and thats the best advice ull get all year long. Keep it in full resirq and remap it. Buy a cone filter for ure 007p and it sounds smashing. This engine is not designed to operate with a DV, so we should not do what its not designed to do, or what?

    I know , but what could happen ?!
    Can't blow your engine/turbo, or whatever.

    It just works and sounds great

    well as Ive heard from those that have tried this its ok for a while until you get a fault code, and you will get a fault code. Im sure someone else here have more info on that one...

    I just dont understand why you wanna do that, bcs you loose hp that way. Your car will be SLOWER. Its not a mod, its sabotage.

    If I get a fault code I will reset it.

    Love the sound, it's awesome !

    Why would it loose hp ??
    It's simply air being dumped

    It will loose hp bcs the air that you now want to ventilate into atmosphere is supposed to be resirqulated back into the system. The lost resirqulated air need to be replaced with new air from outside the airfilter. Ie. the turbin impeller will have less air to spool up so it will be slower to react and the compressor has less air to feed ure engine under initial acceleration= less hp under acceleration.

    I ran with a Split R valve in hybrid mode and noticed 1 psi higher boost all along the acceleration rev range after switching to full resirq.

    I emailed Forge :

    "Hi , Just wondering : Couldn't the DV007P be used as a BOV (full atmos), when I simply
    leave the output pipe open (not connected to airhose) ?? I guess this should work, not? And
    Yes : I am aware of the fault-code/engine light issues. But it couldn't physically damage the
    car, or could it ?


    Reply from Forge :

    " Yes it will physically work. It wont damage the car, but some ECU’s will drop the car into a
    ‘limp home mode’ because it wont see the air you are now venting to atmosphere. "

    Regards
    Peter Miles


    So I guess I have the forgiving ECU type then?

    Everyone who's desperate for a REAL 'woosh', just try it once.
    You'll be amazed.

    But be advised that you will need to be able to reset fault codes
    if they should occur. In my car they didn't.

    I don't get you ?

    Drove my car with DV007P in full recirc, for 4 years now.

    4 years long I have been told it's not possible on our cars...
    And been scared off (on this very forum) for engine lights and fault codes ...

    Now I thought : what the heck, let's just give it a try ...
    I simply disconnected the DV output from the hose and I'm amazed !!

    Wish I did that 4 years earlier ...
    I have an ear shattering Woosh now ! Finally
    And it runs like hell

    You dont notice the difference?

    If its remapped there should be a pretty significant difference....

    Had my GFB 50/50 on for a long time now with no error codes at all.

    Some want a dump valve noise, some don't.

    I get enough turbo whistle and dump-valve noise from my Pipercross induction kit and DV30 which is a full recirc - had the full atmos DV on my RS Turbo and prefer the more "understated" looks and noise of the LC :)

    He is talking about 100% dump. NO resirq.

    I've gone and done the same on my leon and its fine, no errors (vagcom'd). I have a forge 007p full re-circ running on fully atmosperic and it dumps realy loud, turns loads of heads. AUQ engine code.
