At work we have some stuff, CNC mill/lathe and non cnc mill/lathe and everything i need. Sheet metal cut machine and bend machine.. I don't know the correct english term but i think you know what i mean

This is how it looks right now. The 3D prints works good, very stiff and made out of ABS. The prints were very cheap to try it out first at only 25 dollar

Oooh, I'm going to have to work my way through this thread.
https://cimg6.ibsrv.net/gimg/www.mia...7a63575ed5.jpg Here's one I'm working on - not done obviously. 3d printed core for a home investment casting of an intake manifold. This specifically is to fit an Arctic Cat 50mm throttle body pair to a heavily ported 13B to go into a Miata based Locost. https://cimg2.ibsrv.net/gimg/www.mia...28d0636423.jpg The homebrew foundry itself. Oil burning furnace burner - works great. |
OoOoOo.... I like!

Since you have access to a lathe, I recommend turning a plug and pressing metal velocity stacks. Unless you don't have access to a press, but the harbor freight presses are cheap.

More info on the foundry? I've wanted to build one for years but have never taken the plunge...

Looks good, also have a press at work. Was it easy to press? lubricant and one shape to form it?

I like it, only need to place it on the mill to flatten the surface and paint the plenum black.
But im happy how it looks already, buddy of my did the welding https://cimg6.ibsrv.net/gimg/www.mia...2d7a5210f6.jpg |
In for dyno. Great welding BTW.
|
Looks good!
|
What runner length did you end up with? Obviously with the air horns as you have them you can tailor the length fairly easy so long as you have room inside the plenum. Nicely thought out and applied. In for dyno also.

Needs comparison dyno with squaretop all other things being equal.

I have been practicing tubing joints and experimenting with the mig like tig thing. It's slowly getting better. I think I'm going to dial back the intensity of the whip movement and worry less about getting a tig look. I have another 16 feet of erw showing up that I will notch into 4" pieces for practice.

It fits and works, now it is time to clean everything up and retune it. I will post some result with a virtualdyno plot.. old vs new manifold.
Also need to re-install the LS coils again Its a little bit bigger than i thought but i think it look good, so i will see how it drives. If it works will my next step is MR-2 powersteeringpump, BMW waterpump and V mount radiator setup https://cimg5.ibsrv.net/gimg/www.mia...18c6ea562c.jpg https://cimg6.ibsrv.net/gimg/www.mia...b36850329f.jpg https://cimg7.ibsrv.net/gimg/www.mia...3f523ce0e3.jpg The engine bay itself isnt very nice, but thats because this was a very cheap car i have bought after the accident with my 1994 NA and i needed a new car to put this engine in. Car itself is in decent shape so it will turn out good when the engine bay is clean |
What are the chances of getting some prints or critical dimensions for that?
|
First i have to see how this works out. Then i will think about it. But i also work together with a mx-5 specialist in my free time so maybe we can make a production version out of cast aluminium

Designed this little guy in the BabyCAD software that eMachineshop gives you:
https://cimg0.ibsrv.net/gimg/www.mia...0059ac42d4.png They are so damn shiny and pretty... 6061 aluminum, each one weighs less than all of the blood in a churchmouse. Seriously, it's comical how little these things weigh as compared to how rigid they are. The two holes in the raised section are threaded M4 x 0.7, and located 100 mm apart. General hole-to-hole spacing is 10mm Because VESA. $260 for 20 of them: https://cimg6.ibsrv.net/gimg/www.mia...c2dc50511c.png https://cimg4.ibsrv.net/gimg/www.mia...49a8369f04.png https://cimg5.ibsrv.net/gimg/www.mia...d6d80e150d.png https://cimg7.ibsrv.net/gimg/www.mia...51a5318e8b.png https://cimg9.ibsrv.net/gimg/www.mia...afbf1664f3.png |
