    The best material in the world at transferring heat is gold, then iron btw...that was an overall conversation point...not pointed at you. Injection molding is expensive to start, but depending on the type of plastic it could take a part from $100 to cast (not machine or finish) to $10, so it depends on numbers.

    However, foundries probably pollute more than a injection mold shop because the air set sand contains polyurethane and when it gets wet it seeps into the ground, that's bad news. Lost Wax and Foam are pretty clean though. That is why it is rare that a new foundry opens up, most of them that I know of are so old they are grandfathered in to decades old environmental laws.Click here to enlarge-That's an old foundry, get it?

    All I have to say is: 3D printing! Think of the possibilities...

    EDIT: You can rapidly design any kind of housing, flange, manifold, connector, provide that the material is up to the task.
    From all the things I've lost,
    I miss my mind the most!

    I'd print a car with metal turbos.

    They have much better thermal insulation (i.e. heatsoak) - just like a plastic manifold. That's where the emissions come in - cooler incoming air/denser charge.

    They should have mentioned that in their press release. They just mentioned the weight.

    I agree - and just to be clear, that was just my guess... I am thinking it's right though - as I doubt cost is a factor, and doubt weight is either. I guess both of those costs do go down however, but thinking it's more for the IATs.

    ...could this be an M3/M4 sign? 4 years of development you say with an N54 housing?

    N54 is not a German 2JZ lol

    They aren't using this for the turbine side just the compressor side, sounds good to me.

    As long as they don't recycle the N54 WG-setup, it's fine by me

    They used the N54 housing because that is what BMW had 4 years ago.

    Yup. Soon enough our tiny stock turbos will seem awesome simply because they dont burst past 10 PSI...

    I had this thought too, especially after all the chatter about 3D printed guns earlier today. But I figured people would print water pumps and junk; never thought about cold side housing on a turbo. This is going to get really interesting...

    Doubtful that a home 3D printer is going to produce a mold that is going to be structurally sound to be used on a car. Compared to a gun (high force), there are a lot more rough conditions a turbo would have to endure on a car (weather, engine bay heat, turbo boost pressure, etc etc)

    Not to mention but the common medium (PLA) is water soluble.

    They do have 3d printers that print metal though...

    you'll be surprised. Not an expert, but they got some crazy 3D printers out there. And as for home 3D printers, must be a baller to have one just for home. Click here to enlarge.

    This has nothing to do with weight savings. You have to read through the marketing talk. This is about cutting cost and making them mass produce for their 4 cyl gas and diesels. All future BMW vehicles are going to be turbo charged. Medal will always be use for higher power cars (6 & 8 cyl). They already secured a company to mass produce their carbon fiber to use in their vehicles; looks like now they are looking for a company to mass produce plastic components.

    So I opened and read this thread and agreed with the first few posts about how retarded a plastic turbo sounds (no matter how decent it was thermally)....

    But then I was thinking this might be a smart idea afterall....Instead of one or two big turbos getting very very very hot how about stacking 40 plastic super thermal turbos and making some super HP lol!!! Click here to enlarge (assuming somehow maybe the engineering allows less heatsoak)

    Sounds crazy but maybe thats the idea...and like you all said much cheaper too! Click here to enlarge

    We use these for various things

    Dont know how long it will be before more car components follow the same route but, my guess is not long.

Considering we now know the DMF causes issues at high HP, we have the Alpina trans flash, and we have a built trans going into an AT car this week. Can't wait to see how that comes together.

    1, yes the smilie sort of suggested it had a slight comedy element to it
    2, so how much more money do you have to spend to stop the gearbox going pop?
