The custom 4" I was working on, is now finally in use and working well. There is a slight diameter change (reduction) at the MAF sensor because I don't need volt headroom.
As mentioned before, it is printed from PP-CarbonFiber.
those filters are quite heavy. on my evo9, even with supports(suspension for the filter) the clamp to the turbo inlet needs to be superduper tight. I suggest the heatshielding should be a separate solution (an air box like mine maybe).
What made you choose PP-CF? I've been meaning to do some more research on optimal materials for automotive parts.
Also, 3DXtech has their PP-CF on sale right now. I might have to pick up a spool.
It is OIL (ie:m oil/air breather tube from valve cover in design) resistant, fuel resistant, and even ethanol resistant. It is super lightweight and can handle the under hood temperatures. The final icing on the cake is that it is cheap compared to PEEK or Ultem 1010. This PP-CF is actually from 3dxtech, and this project is in the review section for the filament. At the time I did the review, I had to print it slow, but now found I can print at 100mm/s no problem.

The rubber end of the filter is touching the frame, so it isn't just hanging weight. The rest of the intake is super light, so I am sure that helps. The shield is for water coming in the Evo X hood vent, not for heat.
Will be interesting to see how it holds up with vibrations and such along the layer lines.
So the filament has extremely strong z-axis bonding, and is considered to be very tough because it has flex compared to other filaments. However, to make sure I didn't end up grenading the engine or turbo I made the walls something like 3 or 3.5mm THICK (100% infill). I did use DEI gold reflective wrap around the section closest to the turbo inlet to make sure it doesn't get too much radiant heat, pushing it into the soft zone....
The ultimate tensile strength is beyond OAK...(70 vice 78 Megapascal).
Happy new year fellas. Has anyone come up with a UICP clamp yet? I don't want to weld something because mine is Ti and they reject the heat sooo well. So something adjustable that fastens here and here and would work for just about everyone. Didn't matter the clamp, I've used em all, they just can't take the vibrations and abuse for these duration's. If you wanna come weld some vbands/clams up I'll let ya

where does it not work for you? my t-clamps for the turbo inlet and the on the TB have rivets on them for the extra bite. once the t-clamps are installed you can add brackets and stuff from the clamp bolt
Yep tried em both, Daytona is another level of pressure on the system. Can't emphasize enough that you go clamp, or you weld clams, that's pretty much it at this point. So I need something that comes off the TB or sits off of the brake booster or struct tower area.
