cool, so the dotted line is stock w/stock air and the solid line is w/carbonio? if so, i see no benefits until around 4000 RPMs at which point the carbonio is superior. the stock airbox actually seems better up to about 3500 or so.. looks like the intake totally destroys the stock airbox around 5000RPM and beyond, but since i rarely shift any higher than 4500 RPMs, looks like I'm not missing much. there being a 30HP deficit at redline doesn't mean a whole lot to me in 95% of my daily driving.

This is on the dyno. On the road you have far more air rushing through the intake the faster you go. Id expect to see gains at all RPMs.

Hmm, interesting. I do mostly city driving where I just scoot around - that is where the Carbonio shows good gains for me. DSG in city traffic shifts early which is great for relaxed, effortless commuting.

Looking back at the data I compared run 1 vs 1, 2 vs 2, 3 vs 3, 4 vs 4, 5 vs 5 and 6 vs 6.

By run 6, the gaps were getting larger further down the RPM range. : )

Correct, I already have a stage 1 tune with the stock intake. So, I'll be comparing the stage 1 tune with the stock intake vs. stage 1 tune with APR/Carbonio intake.

I did not see any boost loss in the upper rpm range with my modshack.

Different car, different conditions, different location, etc. etc. etc.

Buy a pflo and test it. Bet it is same or better at high rpm than carbonio.

Though I totally agree, there have been AT LEAST a half dozen instances of it occurring on here.

I would not say test an AWE CCBI intake with a GIAC tune against a Carbonio with an APR tune. But you could definately test both intakes on the same car with the same tune. I would recommend though only comparing Intakes such as Carbonio and Neuspeed that keep the MAF in the stock location using an APR tune.

I picked up a Carbonio today at PureMS. Looks like I made a good choice.
I think this is a valid argument. Perhaps the better way to do this comparison is WITHIN a given tune.

So you would have
Stock w intake X, Y, Z
APR w intake X, Y, Z
GIAC w intake X, Y, Z
Unitronic w intake X, Y, Z
Etc.

just thinking that would give people really the best actionable data...

That said, we are talking sample sizes that we can't get at.

Thanks again, I think there is some great info in there. We need more people willing to do this kind of testing. How about a IC comparison next

I would like to continue the conversation Bender started though. 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?

The reason I ask is I want to know (and I think a large number of people) the advantages between one brand and another may not be a big a deal until we jump into the big boy pool with a K04.

I think the difference in tunes to be a small matter when compared to the above issue.

Please feel free to poke holes in my theory.
