Drivetrain CAI for R56 (home made)

Since I saw on a previous post Siliconeintakes.com did not have in stock for the bending reducers to make the DIY intake, here are some additional sites that provide the same product:

Here is what the intake looks like now with the bracket that I have made. The bracket is made by bending and polishing a piece of 30mm aluminium. The pipe is 3" aluminium pipe that has been polished and attached to 3"silicone elbow. The filter is a 3" K@N dual cone.
And this is the way it sounds like in the car, initially I am driving at normal everyday spend and acceleration levels. Then I have opened it up a bit in an area of sufficient speed limit so you can hear the bypass valve and the turbo gulping the air in. During this video the drivers window was open and it was filmed from the passenger seat.

Just a note from someone who has in the past lived in Europe for a good number of years, Europeans, and the rest of the world for that matter, write their dates as day/month/year. Today would be 13/04/2008.

With my home made CAI, the JCW strut brace fits just fine..

Back in this thread it is mentioned a few times.
Also, check the R&D thread/website on ALTA's intake and I beleive you may also find some similar info.

I have been running an exposed K&N filter directly connected to the MAF with good results. It is a more direct method and have even shortened the intake hose. No CEL's, the turbo spools up quicker and got 38 mpg last tankful. Tried posting a picture, but my digital camera has too many megapixels and exceeds the attachment limit. Very clean installation though.

anyone know where i can get some aliminum piping, 2x 3 inch OD, 2 inch in length? or would this be easier going to a local lowes. siliconeintakes is taking forever to restock their stuff and keep pusshing back their dates. i need to find two joiners for this thing...

So far no codes or issues with the air/fuel ratios. The key is making sure you don't have too much oil on the filter.

I forgot to add that Australian Minis do not run a MAF, just two MAP sensors. i am a bit worried about AFR's and I think I need to arrange some dyno time soon. What do you all think about exposed pods on MAFless systems in regards to AFR's?

I picked up a 3" ID to 3" ID SS pipe section at AutoZone. It will work for now. It was a little long, so I hack sawed (then smoothed) about 1" off of it. The whole thing was like $2. Do not get a 3" OD to 3" ID pipe, the 3" OD section of pipe would be about 3.25" in diameter. I know because I made that mistake.

when it gets here and i am wrong... i guess you can be the first person to say, "i told you so!"

Just out of curiosity. . .does anyone here feel that in the lower rpms it seems like there is more turbo lag and does not get up and go as much and that there is more power arond 4K rpms? I decided to clean my filter a couple of weeks prior, put on the stock system and noticed and increase in power at low rpms. I put my DIY intake back on the other day and it confirmed it for me that I feel a lag in the lower rpm range.
I wanted to post this as I wanted to see if any other DIYers had noticed the same thing.
I did notice a significant difference with gas mileage 4-5 mpg difference (better with DIY intake)

a 3" OD to 3" ID? wait, how is that even possible.... am i incorrect to say that OD - Wall thickness = ID? i ordered mine online and went with aluminum. the outer diameter of the pipe is 3" and the wall is 0.065" thick, making the ID less than 3". i guess i wont know until i get it but it will be alright i hope. it was only 12 bucks which is a lot cheaper than most places online that sells the joiners for 18+ dollars...

but... hey, you win some you lose some. is the lag that bad that its not worth the up in mpg and sound? all personal opinion i guess

Probably because it is sucking in hot under hood air until vehicle movement allows air from the scoop to flush out hot air with cool air. My theory anyway as I have noticed the same thing.
