It would be interesting to see what the results would be w/o meth and upgraded fmic.

I understand that I haven't taken all measuring parameters into account, but I'll put it to you this way...I did this test on Saturday morning. It took me up until last night to post this. There was a lot of data for me to go through and analyze (but I'm sure you know about this since you've done plenty of these tests). This is the way I'm thinking about these tests---It's obvious that the stock air box is restrictive with that much boost and the DCI is a better alternative, but as i stated before, I had the DCIs. I hate the way it looks and sounds. This test not only showed as good of results compared to the DCI, it showed better results--TWICE! Margin for error? Maybe, but look at the worst run with each intake and compare it to the best. There's no doubt in my mind that this test showed that my intake was superior. I don't know if you have a Vbox, but when you are finished the runs, it only shows to the 10ths and it rounds. For example, the following runs were displayed as follows: Mr. 5 Intake Time 4.63 Displays 4.6 Time 4.63 Displays 4.6 Time 4.66 Displays 4.7 Stock Time 4.73 Displays 4.7 Time 4.68 Displays 4.7 Time 4.69 Displays 4.7 DCI Time 4.67 Displays 4.7 Time 4.72 Displays 4.7 Time 4.70 Displays 4.7 Mr. 5 (Again) Time 4.68 Displays 4.7 Time 4.62 Displays 4.6 Notice that I could have just diplayed the rounded values but I reported actual results.

Mr. 5, this is superb info. I am not disputing that. I am simply stating that the difference appears to be so small, and within the margin of error of the device among other things, that making definitive conclusions here is not possible. |

Exactly what I was thinking. I have a feeling Mr 5 intake would have a greater margin of victory if meth and upgraded fmic weren't used as those significantly help the short comings of the DCI.

Mr. 5,
First off: Very good work! Honestly, I was not surprised at all with your results. Coming from the VW/AUDI scene, I can share some experience with the experiments we did back then and people posted in the VAG community. As stated in another thread here, for me, the BEST intake is the one intake that provides optimal filtering capabilities and also providing maximum air flow over the widest powerband. It has been determined that the most successful intake would be to have a smoothed, gutted and polished airbox and a quality OEM paper filter. Its seems to me that with your intake, you are going one step further, by supplying additional clean air from a second source. P.S.: That Dinan intake, might not be so bad after all ...rather expensive though! |

BTW, I never showed the difference with the filter that I was initially using and the filter that I'm using now.
The filter that I'm using now is the Macht Schnell DCI filter and has a 3" opening. I purchased an aluminum 3" pipe that connects to the 3" ducting. As you can see, there is very little restriction.

The fact that the average boost with the Mr. 5 intake AND stock intake is 14PSI and the average boost with the DCI is 14.3PSI is interesting. My conclusion is that the DCI sucks less-dense air thus more air is needed to supply the needed amount of oxygen to the engine, needing more boost. Colder air is better

I wanted the least amount of restriction but only cold air.

The results should (and 99.999% likely) be the same.

Cool info.
So about .04 of a second is all you gain, about one-half the bumper width, or 3 feet difference. They are all basically the same them in essence. |

It's not just about that. It's about your turbos not working as hard with getting more power.

I'm sure the results would be nearly the same. My concern is with the amount of space. Looking in my engine bay, I can't imagine a 3" hose fitting. Since I don't have an e90 readily available, I cannot tell if it has the same amount of space.
Anyone know? |

I am with Mr 5 on this. Say what you want, but it take from someone that has had all 3 types of intakes on his car. I just got the Dinan intake installed couple days ago. Wow... expensive yes, but seriously, best intake out there bar none. I have absolutely no regrets. If I had to do it all over again, I would still do what I did. I thought about this and dithered for a long time, after finally experiencing it in real life driving, I am a believer.

replace that corregated hose with some mandrel bent piping and your figures most likely will get better. Air flow in those hoses is not smooth.

I got it from Mcmaster carr.
I'll try to figure out the exact part number but it's really flexible and very smoothe inside.
