This is by far the most complex part I have modeled and its taking a little while.
I'm not particularly interested in the outside features as this is only really for CFD.
Modelling to do list/WIP
- Runners are a constant radius
- Flanges to be squared up
- Overlength runners to be trimmed
- Plenum interior is only a mock up, needs tidying
This is the current state of play:
Just the model
And a bit of a catch up.
You've probably spotted it in the model but I have chopped up the flange on the manifold to fit my k20a2:
I've also spent far too long cutting up little brass spacers for the bolt holes:
That'll be okay for these prototypes but definitely something I need to find a better solution for going forward. Ideally i'll find some similar sized unthreaded spacers and then adjust the flange thicknesses to suit.
Printing is mounted up and i've added some temp strips that will show the maximum temperature they have reached.
One on the bottom closest to the printed parts and likely to get hotest
And one on the runner because it will be easier to see when the manifold is installed
Printing should be okay up to about 150c. These strips measure from 70c to 110c. In reality I don't think I will even get a reading on this top mounted one.
I'll add hotter strips if need be.
Manifold should be going on the car this week to start durability test while I finalise the CFD model.
Once the plenum model is up and running i'm going to work on improving flow distribution between the runners by trialing slightly angled trumpets. Once I have a few that work well they'll be printed for back to back testing.
amazing work. I am looking forward to the digital version. Are you going to add a wall to the surface?
I'm not sure what you mean by adding a wall to the surface?
