You will have to make yourself a second setup to hold it and machine in two steps. CAD will help you design that since you can project the part on to the workholding you design. I did something like that in this thread and it required a machined setup just to hold it. Your machine coordinates (offset) should be the same for both parts.
http://www.924board.org/viewtopic.php?t=33237
I am also in the process of machining a flange like yours for the car in the thread above. I will make something to hold it after machining some and then machine the rest. So far I only have the design 80% done in CAD and the material.
You are doing an amazing job! I like to see how hard you are working on this. You should start a paypal donation site.  |
Thad's exactly what i'm planing on doing;). The offset has not to be the same because i need to give the machine a new material 0 point for every new side i work on.
Your project rocks to! love to see how far you go whit lighten everything!
PS. Some extra money whut speed up the process (stil a studend so not mutsh incom).
On the moment Thad is what is my begist enemy...just yesterday i received an e-mail of an acquaintance Thad wants to make my carbon-fiber plenum for me. Whit material and labor i will com somewhere around €400,-.
For what i want and get thad is not expensive...but as i sade...money is a big issue on the moment  .
So every donation is welcome   |

Do you have a paypal address? PM me. A person like you and the project needs support. I also want to see how far you take modern technology and apply it to the 924.

Don't wory about thad;). Working on somting...intresting at the moment (in CAD).
Sure you al know the VVT technology. Well i took a good look at it. And made my own version adapted for our 924's. Still have some clearance issue whit the oil channels. But i work Thad out .

You are beating me to every punch and I am happy you are! This is very cool. I wanted to model something similar myself but have not done it yet
Can you build something like this?

Ghehe, sory about Thad . I can make almost all the parts, accept the sealing between the wall an the rotor. the cam gear itself will need to be an original but machined to this specs. etleast...Thad's the plan.
I had no gear so the dimensions of it are not 1:1, but whit som luck i get one soon and finish the modeling in CAD. Run some simulations and then look how to make it in real life . |

My younger past self is jealous of the equipment you have access to
nice job and like I said I want to see how far you will take this project.

Have you considered using a flyweight setup with springs (ala franco) instead of activating it hydraulically?

Well, i only have access to the machines as long as i'm in the teacher good graces .

Yes i have, even had a small discussion whit Martinus on the subject. And he had me convinced, but just couldn't get the hydraulically id out of my head. i like the id one can program the retard ore advance of the cam in stet of playing whit weights and springs. |

Don't want to spoil the fun, but the renderings are the least of the problems with such plans
you don't want to know how much stuff I have designed of which I knew the chances were 1% I would actually build it.
If you want to control such things, you should be able to program the ECU. After that, it will take a lot of time to tune it after that, and before you know it you're 5 years from the point where you actually started building your designs.
Especially when you've got a study/work to spend some time on.
So, I hope this reply will motivate you to actually build it that's what worked for most of my plans.... people told me the engine would blow up with EFI etc etc... didn't listen, did it anyway and it worked. that's one of the great achievements you can get in life.

Can't agree more. I'm focusing on the intake and exhaust first. This is just some brain stuff Thad needed a way out. But how further i get drawing it up...how more possible it seems to become.
Indeed for this product in my case. I think et least 2 years before its on the engine and Thad is whiteout fine tuning in mind.
As i sade. Planing so far is:
-Make the intake
-Buy a 924 turbo engine whitch is ready for screap, disasambel it and draw it up in cad for some measurements for the pistons, drifshafts and turbo(manifold).
-design a air box Thad can accumulate the large are volumes and is suitable for "ram-air"
-Make the air box
-make axhaust menifold.
-find some compony who can make the drifshafts thad i have in mind and let them make it.
-buy pistons valvs cam etc.
A whell you get the pictiur i think... this variable cam is on the bodem of the list |

It has been to long sins i posted here, meanly because i'm busy with school and work. But here is an update...
The intake plenum still issent made, the feller that was going to make the CF product for me isent replaying on my mails . Probbely busy whit school to but can't realy move on whitout it...cous its a key peace in the design.
But....i have bin working on the exhaust manifold, rev. 4 i belive...But this time i tried to locate the turbo somewhere i had more space.
It is sent finished jet, but here is a screen of the work so far.
Need to check clearens (its 5 o clock at night at the moment over here...) but i think that will be ok.
And another good thing. if it clears everiting, it can be made pretty easy |

Can you 3D print the design? This has been my issue as well..clearance
I am approaching it differently than you are. I am working on mock ups on the car. The other issue is the same as yours. Either to use the stock location or to mount upfront as you show in your latest revision.
If you print the design, you could obviously check clearance.

It is possible to print the design. But i thing it is cheaper to make it with 3D bending.
3D printing is a expensive undertaking. And the printer in school cant print such large designs.
I think i draw the engine bey and look at it then.
Here is the design somehow more finished, only the tube on cil. 1 is not correct jet. all the pipes are 450mm at the moment, cil. 1 is 390mm.
