Lets start to build the intake manifold.
After extensive searches I was not able to find anything like this been made.
So first one of its kind. Same sad Kenne Bell and few twin screw specialist from Sweden witch turns out to be great help in this.
Twin screw supercharger was invented in Sweden by Alf Lysholm.
Thats why all twin screws are referred to as "Lysholms"
But Kenne Bell is the only one with Lysholms/Autorotors idea, with 6 by 4 rotor pack design. Far superior to others in my mind.
I feel lucky, as I've had a chance to visit supercharger factory three times.

You will found out that this build is highly dependent of friends..
Man, it good to have alot of skilled friends..

First I set the blower on the engine with piece of I-beam..just to get visual reference.

At that point I had 4.2L blower, witch I did installed to 572 Hemi. But thats another story.

Next I started to draw 1:1 scale plan what kind it need to be.
What kind of air space will I need and get.
Bottom floor spoilers where an a idea but tno needed them.
I already had my special made intercooler core arrived from Europen core factory.
I ordered it as 2 stack 50mmx100mmx500mm( 2"x4"x25")
So it will have two cool shocks, instead of one thicher core. That could suffer from heat soak more.
Capacity to cool over 2000Hp.
With ambient cooled water/coolant.
On the sided I need space for Bosch Ev-14 (1500cc) injectors, one per cylinder.

Under the stock intake is coil packs, couple knock sensors and some cast bosses. They all need to go or atleast relocate.

First plan was to machine it out of 6061 billet, thanks to near by top cnc shop. again one of my friend worked there as sales manager. But when he quit, so did my hopes for billet intake.

Next idea was to make molds and cast it from aluminium with yet another friend. Hes been doing molds and casting (mainly stainless) past 20+ year.

We where just about to start fabbing the molds when yet another friend offered to help. He has huge new cnc-press brake. 100.000t, that 1 million kilograms. 2mil lbs.
So we made the base plate with that. From fresh 10mm plate.
Bend it like it was A4 printer paper. LoL
But right on the money. Great!
I was educated that aluminium ages, old plate brakes..

Now I've made welding jig, from 15x150mm I bean, cutted in half, welded it to 50x100 with 6mm wall bottom tubes.
Will fit to my powder coating oven for pre-heating.

Next cutting front and back plates from 10mm plate and injector bases from 50x50x10mm L-bar.

and I still have just a few details to figure out..My design lives...All the time..

Intake build continues.

Pieces are made, beveled then after preheat oven welded. Was heavy to lift to oven, complete jig and all...
Those angles are so that I've place to mount injectors and fuel rails. As was in my CAD (Cardboard Aided Design)
Not gonna weld bungs on it. Just mill spec bore for them.
Never mind the finish of those welds. There is 3 passes.
Main thing is that its over the surface and penetrated.
All will be machined smooth.
Made top plate, first, will not be final one. I can tell you that.

Then we arrive point of my life when I got job at trade school machine shop foreman so now I got tools, a lot of machining machines and full welding shop other side of the hall... You will see that also..

At summer holiday, I reassembled the engine to manual milling machine table and let the chips fly..

Back to this, after talked with Swedes again. Desided that I need to make risers to make room for air. So I machined them. made a step joint so I can be sure they don't move or leak. milled o-ring groove and holes for allen bolts on it.

Next will make mounting face and - plate for the supercharger to be bolted to intake.
