    Baffle in ATS Intake

    I removed this baffle out of the can that the air intake connects to right before the turbo. Wondered if it was just a baffle to cut down the noises from the turbo, or had a performance purpose. Turns out it has no effect on turbo noises, and I could feel a real power loss in the pedal. After looking at the whole setup closer, this unit is more of a funnel into the turbo than it is a baffle. I put it back in and definitely felt the power return. Just a friendly FYI.

    Uh oh. I predict a bunch of aftermarket "funnels" each claiming to add 10 HP.

    Re: Baffle in ATS Intake

    Couple of simple explanations for this could be:

    It change from laminar to turbulant flow making the turbo work harder to get air into it.

    The change in flow caused you to run lean because of air not hitting the maf correctly.

    But I do not have a 2.0T and can not go see the location, nor know if the car is even a MAP or MAf system. Both of these ideas could be crap, but I have seen it happen on other cars where a tune is needed to correct the vales the MAF is giving. 3000GT's were a perfect example of this.

    I doubt if there is one in Pfadt's CAI.

    There isn't.

    I wonder what effect Pfdat's intake will have on the car.

    more noise on a stock tune lol.

    oh and if you look at the diameter of the inner portion of that "Baffle" its the same as the diameter of the rubber tube. I'd imagine removing it would create quite a bit of turbulence in that wide "Chamber" just before the tubo. The baffle acts like a tunnel, streaming the air, and removing it suddenly exposes the intake to a wide sudden hollow then crammed back into the bottle neck of the turbo.

    Hey there, just saw this thread and figured we would chime in. We were surprised to see this too when we started developing our intake late last year. We dyno'd with and without this piece, no performance in this at all, it is just a "noise suppressor" for the intake. If anything, you create potential to lose power with the piece installed. If you perceived a power loss it without it it must be attributed to something else in the mix.

    We will for sure reccommend that everyone keeps these baffles installed in the OEM intakes. No reason to take them out. As for our intake however, we do not need anything inserted to make power!

    I didn't think it would be there. Sort of like the baffle they had starting with the 2008 Corvettes for harmonics reduction. What harm would a little turbulence be if the air is then sucked through the turbo, pushed through the intercooler, then through the throttle body?

    Re: Baffle in ATS Intake

    well take it out if you want, nobody's stopping you, but I'm saying, I took mine out and didn't notice any power gain/loss and relatively NO extra engine sound, so why would you remove it then? its clearly there for a reason.

    You know what it looks like?

    An anti-surge compressor inlet molded into a piece of plastic instead of into the aluminum.

    Makes sense, too.

    My new Pfadt intake is on the way, no need to play with the stock intake.

    damnit, this is an intelligent guess at it's purpose. I should have thought of this first.
