Because it's a casting and the inner core needs to be supported somehow. They all have 1 on each side.

Edit, just went over and took a pic of mine.

I'm very aware of those. Have 2 of those bikes in the garage. Not what I'm talking about though. If you look at the pic I reposted, I even drew a big ass green arrow that points to the hole I was talking about. I even circled it too, just in case somebody got confused about what I was talking about. :flipoff2:

There were so many scribbles I didn't know what was going on. :flipoff2:

As far as I know all the ktms have a hole there on each side. I always thought it was a drain hole for water or maybe its a casting hole. I'm pretty sure my old kawi has them.

edit: we have a couple here. Seems like the older ktms that were polished did not have them because they are extrusions maybe. All the ones I see that are raw casted have them. Could be because of the chain adjuster area is different in the 2.

JR4X don't forgot to post your dad's carnage from Crandon.

After all that anticipation I just have lamo pics. In all the hustle of fixing things in the pits some broken pieces got tossed before I got pics and the shock got sent to our shock guy also before picture.

Broke one front and one rear 300M RCV and these don’t twist off clean. They burst and expand and both of them did it right next to the splines inside their respective carriers. It ruined the spool in the rear but the ARB survived miraculously.

Still shared some impressive carnage.
 
This is the inside of a $30k PSI screw blower off the guy I work with top fuel engine. The way the rotors are made blows ours and everyone who has seen these pictures minds. There literally has to be several thousand slivers of metal making up the male and female rotor and they ALL have to be slightly different to form the twist.:eek: According to PSI those pieces are all "laminated" and then the rotors are Teflon coated. Unfortunately they also come un-laminated and destroy themselves......

Any idea why they would build them this way instead of using a 5 or 6 axis CNC to carve the male and female rotors out of solid cylinder of metal? In my brain it sure sounds like it would be a million times easier that way. :confused:
 
Each laminate is cut then rolled in some kind of mandrel while being welded together. I mean I assume that is how it is done:homer:

Each piece has to be cut slightly different. Rolling the same piece over and over wouldn't produce that shape and in my mind would end up looking like a roots style blower with much straighter rotors.

Could those be made on some kind of super high end 3D metal printer?

Wow. That is completely foreign to me, but so cool. Now I want to know more, the same questions you have haha

Their website and FB page don't say squat about it and their coating pretty much hides the fact that they are made like that. Must be some super secret process I guess....

My guess is that the lobes somewhat change shape in a controlled way as they spin faster and increase boost during a run, all while there's a fuck ton of fuel being dumpped in at 500psi.

Those engines run so close to being hydro locked it's not even funny.

Impressive pictures for sure.

My wild ass guess would be its an oddball material not readily available in a billet large enough to machine as a solid piece. The laminate may be a work around to that. Cool as hell for sure. :smokin:
 
I think that they have to be stamping them out. Look at electric motor rotor and stators, they are laminitis.
 
Stock Dana 300 gear set broke and blew up the case.

Dang it, we're you running a upgraded d300 access cover or any kind of a back brace/spine?

I was not

Are you running 6.17 or 7.17s in the axles?

Also, you want to mate a lt230 to that eco box, I'll trade you for a 3.8 atlas :flipoff2:

I am running 5.13s but have 6.17s to swap in. Come drop that atlas off, I’ll find a use for it. :flipoff2:

I'd think the deep axle gears will help the tcase survive. Adamwende mentioned a buddy breaking 35 splime cromos with a sami case due to 7.17s in the axles

I'll drop it off as long as I can leave with a 231/lt230 doubler :flipoff2:

Or those 42 miles stars and 20s .

Picture of the guts here COATINGS

They make it sound like "wear" is normal

Due to the variances in coating material, coating hardness, applied coating thickness, etc., it is absolutely “normal” to have visible areas of “raw metal” exposure. These exposed areas may appear on either or both rotors (Male & Female) as “feathered”, “worn”, “burned through” or “burnished” on the softer production coatings or as a “chipped”, “shattered”, “flaking” or “delaminating” on the harder production coatings.

Because metal moves. The most fundamental rule of metal working. I bet its too much of a pita to control the shape as metal is removed and the billet is stress relieved. Not to mention the cost of a chunk that big. Lasering a bunch of pieces and assembling/final machining is definately way more cost effective here. IMO.
