Definitely agree with mad Mike on the 20B being one of the best rotaries! The 20B sound is soooo much nicer than a quad rotar in my opinion

What an awesome vid. Madmike is a treasure . I feel like he’s one of the ones that’s kept the rotors alive and provided that interest for the youngins of today to develop the love we all had for these things when we were young. Hopefully I can meet him one day

I love every episode with Simon. He's such a chill dude!

They really are beautiful pieces of engineering.

What an emotion. Engines hit home for me as an enthusiast. I'll be honest im planning down the line to build a 4 rotor ultima RS with dct manual box. 😊 . ICE cars are the way of a man , no ev💪.

That's awesome to see! Looking forward to seeing that in one of Mad Mikes cars 😍

This is like the 12 rotor engine that was also billet made in America. Rob Dahm now has it and is doing some precision work to make it run perfectly smoothly but the work that has been done to it is nothing short of phenomenal

I would really like to see a 5 rotor! Is there any aftermarket stand alone ECUs that can manage a five rotor engine?? I know it’s sorta like managing a 15 cylinder engine. Pretty sure it would be complicated.

Renesis side exhaust 20B setups will be great. So long as tiny thin side seal springs are not stressed with turbo heat, they will handle other types of boost. Side port exhaust allows more powerful burn of the fuel. Multi stage intake of Renesis allows better air flow at all RPMs.

@vinniesmith7455

Indeed would be cool to see that and shit you can just mill out the rotors from a reny to 3mm and they’ll chooch ! What would be cool is 20b reny fully NA for sure ! The intake ports are already gnar the way they are …. Be really cool to see itb stacks on a reny also! Was working on a CAD design for the 6 port but decided the four ports area better go for ITB !

single rotor turbo in a kp61, thats always been a build ive thought would be sick.

Would have liked to see their machine shop

That moment you get caught up and cannot decide on what direction you want to go !

God those things look beautiful

Hows those anodised plates!! sick!

I don't know why the billet sideplate engineers haven't considered making Renesis type sideplates. The Renesis hybrid 13B is a type of engine parts combination that's gaining popularity for equalizing the breathing specs on both the intake and exhaust side. And the housing that are most commonly used due the most bolt-on compatibility, the GSL-SE, can still be bought from Mazda or secondhand in great condition. A billet Renesis hybrid would take abuse if it's turbocharged.

There’s a 1 rotor Porsche 356 on the Tube that is absolutely amazing.

Mazzei formula has a 5 rotor or is getting one built

I think Rob and BilletPro are going to work together in the near future. At least Rob mentioned something about that in one of his latest videos, and he recently received a big shipment of parts from them. Rob is bringing a lot of attention to rotary engines, and he could bring BilletPro a whole lot of new customers.

It will be mad to just order a billet Semi PP 13B crate motor over the internet!

Hey bro, can you send it to Indonesia?

theres a none friction coating would be good on the plates

For drifting you use billet steel over billet aluminium.

Can a rotary be run vertically? Or do they still use a oil sump? I know they use 2-stroke oil. But I thought they had some sort of a sump for the gears too that uses regular engine oil.

Is there a reason they do not produce housings? I have only seen plates in a billet version.

@NorwayVFX

8 ай бұрын

Housings are incredibly difficult to manufacture, and Mazda's OEM housings are really good so people have always just used those. Also the factory housings are aluminium while the irons are just that, they're cast iron. Going with billet plates/irons removes a lot of weight and adds strength were needed, but until Mazda stops selling housings, or the prices rise too high, the market for billet housings isn't all that big. There are several companies working on and testing both billet housings and rotors, but we probably won't see those for sale as off-the-shelf part for several years still. With the plates you make the whole ''skeleton'' of it out of billet aluminium, then insert the steel plate. The steel plate is ''just'' a flat piece of steel with a coating so the machining is fairly simple. With housings you need to machines the weird inside shape just right with really good accuracy, then spray on a hard coating while keeping the layer thickness extremely accurate and even.

I wonder what our American chap, Rob Dahm, would think of this.

This is a great improvement for the rotary, but who can afford it? This stuff is crazy expensive!

How much lighter are this housing? Compare the stock housings?

I'd love to see a Renesis based 20b..overall length the same...but matching, wider side plates to offer larger exhaust ports with better spacing between them. With 3 rotor housings it may end up being a little bit longer(not much IF the normal 20 center plate is more like a 13g-or short 3 rotor plate) also a semi pp in that configuration would probably be awesome as well. The plates and housings should be easy...the eccentric shaft though...
