    Alot of it could be the tune, but yet again based on the design of the aFe intake system we would see more results in real world conditions rather than on a dyno platform as there will be much more forced air hitting the air scoops to the air ducts.
    I will be ordering a Dashdaq soon for logging, so this will give us more details
    Great! Looking forward to your future findings. AFE should give you a discount given the extensive reviews you do.

    This post will serve as my journal and review of the aFe N54 Stage 2 SI or Sealed Intake part # 54-82002. You might want to subscribe to this post so in order to keep you updated with the progression on this intake. There will be many parts to this review.

    Today, 04/11/2012, I received my aFe Stage 2 SI via UPS. I saw this huge box and was almost afraid to left it cause I thought it was going to have some weight to it. I was suprise the box was light, too light, and I wondering if UPS jacked me for my intake

    Well it seems UPS didnt jack me, everything was in the box as expected. One of my cats weight mroe than this thing...hehe

    The box is solid when everything is assembled. The thickness of the structure is acceptable, I think even better than the stock structure.

    As I begin to take this intake apart, i notice something. ITS NOT TRUELY SEALED ! There is no sealing around the external parts that can be seperated:

    This intake serves more as an "enclosure" rather than it being "sealed" intake. Now the only reason I can see it was designed like this is to allow some sort of "passive" airflow from the stock snorkel.
    For those of us with tuned cars this is not good, as there will be significant preasure loss from the stock snorkel, mixed with heat from the engine bay that will be "sucked" into these unsealed slots.
    However, there is an easy fix for this. Just get some sealing tape and problem resolved and I will have a true "SEALED" intake like the Dinan and Mr 5 setup up. In part two of my review I will show the parts that can be easily sealed up with sealing tape and make it look proffessional.
    If the design intent was to allow some sort of passive air flow then the option to remove the secondary inlet plug would have been the solution instead:

    This secondary inlet leaves alot of potential for this intake if harnest correctly, but first, properly sealing the box is a MUST before installing this intake in a tuned car running significantly more boost over stock.
    This filter and intake inlet are firm and sturdy "together". There is a metal brace in the filter to prevent the filter from collapsing from high PSI. The open mouth of the inlet that connects to the turbo inlets adds support to the filter also.

    After taking eveything apart the box itself stood sturdy by itself. the stock box is thinner and harder, the aFe box is thicker with some flex to it making it hard to break. You can run a truck over this box and it will not break. If you do that with a stock box it will break into pieces.

    The glossy internal is a coating to keep heat out and easy transistion of air and cleaning. the inlet for the turbo inlets also has this coating and as you can see there is nothing but smooth curves in the inlet

    This concludes my Part 1 review of the aFe Stage 2 intake for the N54 motor. Next I will be a dyno run with stock intake, then the installation of the aFe intake after I have sealed it up. I will post pics of all of this or perhaps a video of the sealing. So back into the box it goes until this friday

    Part 2

    I have sealed up the intake which turned out really good. I used a high resistant thermal insulation rubber tape and a caulk gun.The insulation tape is used in plumbing to wrap heated pipes.
    These are the things I bought at Home Depot, except for the pot pie - my dinner

    Turned out all I needed was the caulk gun, the insulation rubber tape, and of course my pot pie to eat.

    I used the caulk gun on the turbo external part of the inlet that is inserted into the air box. After it has hardened I will cut the residue.

    Next I started to seal up the air box cover with the insulation tape and the top part of the box

    All is ready tomorrow (04/13/2012) for installing right after I dyno with the stock intake. After installing I will be heading out the Palm Beach International Race Way for some test runs and for the DME to adapt.

    Overall, definitely better than stock intake, power comes on earlier than before. All I can do now is wait for aFe to release their new version based off of my concept of what this intake is suppose to be for those of us that are tuned. The dyno graph whp, wtq, and afr lines above the others is with the aFe intake

    Part 3 Conclusion

    Attachment 16666

    Note: aFe will be coming out with a newer intake that willl be one piece and completel sealed for those us running significant higher boosts.

    It is also possible that they will address the issue of this intake box not being truely sealed by coming out with a gasket kit for current users.
    Really well done and detailed! Great photos, descriptions, everything. Nice!!!
