    Terrible sorry for not updating the thread for a while, currently I am quite busy with many projects ( some Ducati projects and an R56 :D ) .
    I have done a bit more than 6000 km so far with the charge pipe and everything looks good. Some days ago I removed everything in order to inspect the charge pipe. Everything looks good so far ! foto below: 44187730_543709019375732_8118339963059175424_n.jpg

    Good deal thanks for the update - can't wait till it cools down so we can see the dyno results. Also.. inquiring minds want to know about the R56 project.. Ducati's are cool too. :Sneaky:

    Please do! Ducati is one of the brands my dad use to sale. I have a 69 Moto Guzzi sitting in the garage I need to get running.

    Great work so far. Appreciate your efforts. I also can't wait for a proper before and after dyno.... And of course the estimated cost? All the carbon has this hobo concerned ... But excited

    ‘Hobo concerned “. Hahahahaha I know what you are saying.

    I agree and know everyone’s is making stuff out of CF and it’s very pricey but in this instance I think CF is a great material to use because that OEM tube is a poorly made plastic part. The OEM parts always fails if you just look at it wrong. This guy is doing a great job with CF and can’t wait to see all the data and results.

    For other parts I think CF is not needed unless the weight reduction and strength is worth it and you get a real performance gain from using CF. One perfect example of good CF use is rims, they are stronger, lighter then forged rims and will absolutely add performance increase with less rolling resistance. The only down side currently is they are still very pricey but in time the cost will come down. This is just how new tech works just like Plasma, LCD, LED, OLED and other flat screen TV’s of a few years ago.

    CF Scoops, Mirror covers, trunk handles, door handles are all just for show parts that add no weight reduction, performance increase and looks silly now that everyone is on the fad. I am waiting to see CF floor mats next or maybe a CF toothbrush at CVS.

    Here you can see the printed (prototype as well) jig model. Material used PLA. It's the cheapest material you could buy but for the first try it will do the job. I have done nothing to improve its appearance like sanding or painting as it is a first mock up. I want to make some small changes mainly to improve ergonomics and of course printed it out of NYLON 6 which is the most common material for printed jigs.

    And some more small details that I was working on.
    Left photo: Mock-up bracket. Still playing with the idea of making it from carbon fiber as well. Not sure yet! But at least the bracket, design wise and fitment, it's done.
    Right photo: I added a spacer to the bumper, I used an OEM spacer (all our MINIs have these spacers) just to give a bit more clearance. So far I had no touching but I prefer to be on the safe side.
    Car still need some cleaning !! The white powder you see it's from the scanning! in some areas it;s so hard to reach and clean it ....

    Love it.. I know people know this, but 3D printing is going to change the game.

    Good stuff. Looks like the jig turned out well. Thinking about this a little, since it’s carbon fiber.. which usually comes in sheets, how is that 3D printed?

    I think I miss you somewhere ! The JIG is not carbon fiber , just printed. Is that what you are asking?

    Sorry for the confusion, My question was not about the job, but the actual pipe itself. I.e how are you making the carbon fiber part? Did you do molds or is there now some way to “print” carbon fiber (never seem that). My assumption is molds and then you hand lay the carbon fiber... but wasn’t sure.

    Yeap molds. It is not a one stage mold ofcoure. The chargepipes are made with the infusion method ( and not just hand lay up), oven backed and pressured the same time. That's one of the reasons why it takes me so much time. The prototype I uploaded in the forum it is actually the 5th version of mold design (and the final !). So that means.... 5 prototypes of molds.... machined aluminium... :Banghead::Banghead:
    But I enjoy and the most crucial learn from the procedure ;)
    Last night when I was driving home I did a bit of loging, saw some nice numbers. 16.6 psi 4th gear at 6.800 rpm, without heatshield. Pretty happy with the results. Ofcourse the cold weather helps a lot.
    I will try to update you guys as much as I can, and ofcourse I will try my best for the dyno to happened before the new year.

    This is exciting stuff
    I can't wait for it to be fully done and you test the final product so we can see clearly see it saves xyz degrees and potentially xyz hp gain..... And cost of course.
    Love the 3d printing tec

    I cant wait for the final product as well :D I dont want to rush it, I want to tackle all the small details first.
    So yesterday I went for a drive up in the mountain (Pretty cold, foggy and it was raining a lot) with a friend of mine and I made a small video.
    Nothing crazy just playing around with video editing ( I used SONY Vegas pro, found it pretty nice to edit videos) and smooth 4 (phone-camera stabilizer ) I just got.
    The red r56 you see in the video is my friend's car, a very nice and tidy r56 . He is the friend of mine that actually lend me the car for a full 3d engine scan !! I have some nice ideas that I would like to upload slowly !! But for now the charge pipe should be finished [​IMG]



    and a picture from the r56 engine scan :cool:

    And the throttle cable extension :cool: Below the one that currently is on my car.
    20181203_182813.jpg
    And all the parts that arrived today in order to build more extensions :cool: I want to point out that everything you see is an original BMW component.

    Why do you need that? Did I miss something?

    There is a small relocation of the throttle body. The main reason is to create a smooth air path for the charge pipe. By doing that the throttle body had to be moved towards the front of the vehicle and the driver's wheel arch. Moreover it is also rotated in order to avoid contact with other parts. The oem cable was not enough for just 30-40 mm, in that location. So instead of cutting the excisted cable I made a new extension by using bmw-Mini components. It's a small detail by every time I unplug it and plug it back feels so good! The lenght you see in the photo might be a bit overkill ( its around 120 mm ) but i felt its better that way.
