To me there is a potential flaw in the testing methodology (for anyone who is not K04). The problem I see is the difference in air demands between the stock IHI turbo and your KO4. You have shown very nicely the aftermarket intakes flow better with the increased demands but with a stock turbo the flow is going to be less and the difference will be less pronounced. Isn't a K04 moving more air thus making the lack of movement the stock box can provide a bigger problem?
I must agree with Benders comments. This test only shows us what worked best for this combo of tune and KO4. It is not the best intake for every TSI ever. There are just to many varriables that could sway the out come to make that assumption. Great tread if you are KO4 with 366 hp. Keep that in mind all you STG 1 and STG 2 guys.
MAF readings 100% true test i agree. Max flow of a certain CAI design also true. Mainly i just wanted other readers to understand that the APR intake should not be considered the best just because it can flow more air. If your motor , turbo , and tune do not require that much air than it is not better. It would just be the same. I think that some people may take the test findings the wrong way
Has filter area been figured into any of this? Seen a lot of this design vs. that design, but no one has mentioned filter area. The larger the area of the filter, the higher the potential for increased flow correct? I'm not sure about the modshack filter size, but I'm going to guess from the pics I've seen that it is a little smaller than the carbonio.
OK to keep it simple. I think that the test results will differ on a STG 1 only. By the way what intake tested did have the highest MAF reading at the max RPM ?
People I think are missing the entire point of my post.
First off, its to show the flaw within the actual stock intake itself, not to prove/disprove that the carbonio is the best intake out there.
Secondly, just because its k04 doesnt mean diddly. The physical effects will still be apparent intake to intake regardless of which tune/turbo/downpipe/etc you have on the car. If you have X tune and supply intake R, S, T you cannot make an intake change its flow characteristics just because the Y tune requests a different timing or fueling value. The flow is going to be almost dead on if not exactly the same. I've seen GIAC, APR, UNI, and REVO boosting. All are pretty much the same or very close
Let's take GIAC tuning for example. I KNOW that they tune for higher boost in the midrange on the K04. Since we've exposed a midrange flow characteristic of the Modshack, why would I want to hinder it? Using the data and theory in this thread, you can deduce the carbonio has better flow potential further down the RPM band and thus, a similar intake should pull the same. IE CCB. Even with a MAF location change the flow shouldnt be too much different after the 90* bend within the system. Actually, it might be slightly slower due to head loss.
Open the mind just a little bit more and broaden the gaze. You cant take data like this so cut and dry or otherwise you're arguing minute details that have nothing to do with the testing focus and the results. My purpose was to promote the sale of aftermarket intakes with one minor comparison, since we actually had the data available.
Look at the title of the thread. It doesnt say anything about the Carbonio being the best.
