Technical Understanding: Intakes: Stock vs. Drop In vs. Aftermarket

McQueen77 said:

you are going from stock to APR tune + carbonio, or you already have the tune and are getting the intake? dyno with tune and intake doesn't say much unless its dyno with stage 1 and stock airbox vs. stage 1 w/carbonio. i'm in to see logs.

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.

There's no scientific data to support that at all, and it simply does not make any sense.

Incorrect. If you use a single vehicle for all runs or logs that vehicle with that specific tune funtions as a CONTROL. You will still have a small sample size as obviously n=1.

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.

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.

So you want to be a brand that isn't the best because it's not that far behind unless you're running a K04? Why not just buy the best from the beginning?

Missing my point. My point is more that many tuners may tune to their products (as they should). As a result, using one tune with other products is not necessarily indicative of anything to do with said product, but rather with said tune.
