    Now that my S3 is being retired from the daily commute, it’s getting modded, especially since I've become too attached to it to chop it in for a B7 RS4.

    Really looking for any comparisons between two CAI, namely the Revo, and Forge Twintake. I've not really seen much on the two in comparison.

    Tempted for the Revo as it looks a nice design/ package being ceramic coated etc, and by all accounts sounds pretty nice. But the Forge too looks OK, both about the same price.

    Anyone had both? Any noticeable difference, noise? Fuel trim etc.

    Cheers
    Adam.

    I'm sure i will get flamed, but not heard many good things about the Forge due to the quality of the filters they were using a little while back. There have been a lot for sale second hand in the past few months.

    If it were my money, I would be sending it the REVO, ITG or AMD way.

    I'm sure you won't!

    It would be any of those for me.

    Revo all the way - this has been covered numerous times and I know several Forge owners who have swopped over to the Revo after seeing signicant gains on the 2.0TFSI range.

    I had ITG and the Revo pulled 9g/s more air than it did (roughly 12bhp)

    The AMD looks very refined to me, is it about the same as the revo in terms of output?

    I have a video of my mates S3 which has Revo CAI and the noise is pretty loud to say the least!

    The dump, whine and everything else is impressive!

    I will dig the video out and upload it for you.

    The auto specialist CAI has the largest pipe work of any CAI and look awesome under the bonnet... Commonly known as the AMD CAI because they paid for the filters and let AS use their dyno.

    Anyway, here's the pics of mine, made a big noticeable difference as well...

    K04 has re-circ (DV) valve. I have deleted mine!

    Therefore no pipe needed, so that's a forge plug blank.

    Ahhh makes sense now lol, i thought the K03 has a recirc valve aswell? so would i need to route it there on mine (2.0 tfsi A3)?

    On a K03 (and an early K04-A4 I think) car your DV is intergrated into the turbo housing.

    It was then re located to the front of the engine bay later on.

    On the early cars, It can be moved, a blanking kit can be bought and a pipes to relocate it.

    If you want an intake, either buy a K03 one, or just blank that port off like I have.

    A) BOVS sound good...

    B) Only cold dense air being used, no stupidly hot gases.

    c) Most excess air escapes back through the main filter anyway, with only a small fraction going the re-circ route.

    Yes there is a con,

    the turbo will stall slightly on lift off, but then it's extremely arguable that now your using cold dense air, that'll you'll even notice any additional lag.

    I'm sure as hell didnt, and when Forge tested it they found bugger all difference.

    Then why not keep the pipe on for arguments sake? Surely causing your turbo to stall every now and again could cause long term damage?

    You don't get the noise....and it's not as if the turbo comes to complete dead stop, it just slows down a wee fraction and only on lift off, and with DSG there is sweet FA between gear changes so I suffer no downtime there....

    You cannot notice any difference in terms of spool up.

    I see what you're getting at,but if the DV system works on my car,with a lot more power,is there any sense in deleting it?

    There is nothing wrong with the original setup, but I'm simply justifying the fact that it makes FA difference in terms of power delivery opposed to not having it.

    But you do get the noise!

    So if noise is your thing then go ahead...

    This thread is now a BOV thread! sorry OP.

    my opinion is that rev d oem diverter valve works great. if i didn't get forge dv cheap i wouldn't upgrade. stick a decent intake and you'll get the noise. the more boost you got the louder it sounds...
