    Fun with Autodesk: N54 exhuast Manifold

    Click here to enlargeClick here to enlargeClick here to enlarge


    Hey guys, it's official. I have started a upgraded twin kit for the n54. Here is a quick model I made. It's a log manifold, but with collector aspirationsClick here to enlarge. The real manifold will feature an equal length cylinder 2/4. It would take me about an hour more to have modeled it that way, and I am done for today. It is a T25 flange, cast iron, weigh about 9lbs. It lofts from the stock 1.275 diameter to 1.75 diameter, and, it will flow pretty well, a lot better than the stock manifold which is hollow. I am going to build the tooling by hand, so am starting this while my CNC machine is on order.

    Here are the rules: It will be cast from Iron, stainless is just as heavy and more expensive, I have no idea when I will be done, I have no idea what it will cost (but it will be reasonable bc I can cast just about everything), this is a huge project, so be patient, it wont be aluminum because it sucks as an exhaust manifold material. It will change from this model, for example the flange is just a generic rectangle, this is just a pallet to get my ideas out, so I understand if you guys want input on the design. Let the debate begin.Click here to enlarge

    Looks good for a first draft. I believe the angles of the primaries at the turbo end will get narrower when you'll have a chance to put more time on this. Also, interesting to see to which position you will set the turbos.

    Are those inner diameters? Quite an increase. Bigger ID than stock is better, but wouldn't it be safer to be a bit closer to the stock diameter? I believe you'll work on exhaust ports as well to match them a bit better to the increased diameter.

    Are you sure that manifold will fit within the bay envelope alloctaed for the turbos?

    They are the same width and hight as the stock manifold, so ya.

    I named the intake manifold "Project Masher" which is a combination of my kids names, Mady and Asher. I think this one will be called "project Desire" after my wife Desiree.

    Keeping it this way would get this done rather quickly. On the other hand there is no limit on how much time could be used on planning and fine tuning - other than the urgency to get to enjoy the fruits of it...

    Ya, the manutia of flange hole location, runner angle and theory take up a lot of time. Building a manifold is the easy part, I'm freaking out about down pipes, but I'll get it.

    Oh, good stuff. Looked bigger. For downpipes, in my experience it may be easier to fab the downpipes on the car first, and CMM it after for production. If you dont have the subframe .prt files, I know how difficult it can be to CAD blindly.

    Any way you can attempt to make a merge collector? That really helps improve the flow characteristics of log style manifolds.

    You are correct. I am actually going to build the kit from the DP's forward. I have to cast a stainless turbine port that will loft from the Garrett flange to a v-band. I REALLY want to be able to utilize existing DP's so I don't have to come up with that solution,and the kit will cost less, but this is an aftermarket turbo kit so the person who wants this won't mind a little change.

    One step at a time people. Let's see the intake manifold delivered first before we blow our wads over computer generated models.

    Ha, the prototype for the turbo kit will be done b4 the intake manifold. I can build the tooling for the turbo kit by hand, the intake manifold will be a complicated mold bc of the way I have set the parting line. That is why I am waiting to cut the tooling on the CNC. The 4g63 manifold I made took about 40 hours for me to just build the tooling, that was after work, on Saturdays, after church on Sunday... It sucked. It would be twice that amount of time for the N54 bc of the angle. The CNC machine will cut that out in about 5 hours. It looks like I am taking on two large projects at one time, but I am not. When the intake manifold 3d model is done, I will shelve it until September. In the mean time, I can build the turbo kit.
