[@NorwayVFX]

The fact that the original designer and builder of this one of a kind engine specifically reached out to Rob for this speaks volumes about how far he has come. There are so many rotary shops around the world who would kill to get their hands on this thing yet he chose the one and only Dahm. Tyson is one those guys who does not ask ''why?'', but instead asks ''why not?, when prompted with a challenge. There are so many unique one-off solutions in this engine that may seem obvious when looking at it here, yet no one else have done it. And the fact that he proudly shows off all his work instead of keeping it a secret to himself, like a lot of rotary shops like to do, is so incredibly cool. I can't wait to see what it is capable with all the modern tech hooked up to it.

[@JurisTruedge]

Im sure thats why he went to Rob. He has totally designed his own modern injection and timing map for a 4 rotor turbocharged engine. To get the ignition timing and fuel injection to work together is something Rob has learned to do from the ground up.

[@Raczoon]

Tyson is a brilliant engineer. Adding Rob's know-how to feeding his monster should offer interesting results. What a team-up this could be.

The gentleman also said, "...on my bigger diesel one." OMG is he saying that he has a bigger diesel version of this beast?

[@Ikaros---]

I'm still confused about the balance... the left and right 4 rotor banks are counter-rotating, but the bottom bank doesnt? I guess it will still torque somewhat, but no more than a regular 4 rotor. At first I thought the layout was going to be like 2x 6 rotors arranged in a V configuration, but it's more like 3x 4 rotors in a W configuration.

[@eiho]

Right down to the balance cancellations through counter-rotating the assembly, the increased torque via dual lobe firing is like an epic level of engineering 👌 Lastly I'm going to state that I saw the video clip of this engine running with a glass of water sitting on the intake......in the video he revs the engine and it doesn't even make a ripple in the water in the glass! The balance is by far the best I've seen of any combustion engine yet?

This is absolutely insane to see! The simplicity of a rotary engine allows for the world to do these things, this is nuts!

[@GermanJet]

I remember many years ago seeing the potato quality video of this beast... and im still in awe to this day on the level of engineering this man put into this. Seriously beautiful piece of craftsmanship.

[@georgeyoung613]

Another great video. This engine is amazing. I would not have believed its creation not to be possible had I not seen this video proof. I am eagerly awaiting your next video on this incredible creation.

[@sawyerclark8216]

That's the most beautiful engine I've ever seen. Both from an engineering standpoint, and aesthetic. Incredible.

[@802Garage]

A great example of what happens when someone who has tons of experience pushing limits outside of the rotary world comes into the rotary world. Crazy how simple he made the complexity. Awesome opportunity and video.

[@biro24]

It was built 15 years ago, Whoa!! Counter rotation 😮 it’s incredible how big a Big block is, this engine is far above my level of understanding, but I can appreciate the sheer genius of even thinking of let alone making such a engine 😃

[@jayceecombs6887]

My brain is trying to believe my eyes, & process the beauty, the expected braun, & just the "Amazingness" of what I am witnessing! Thank you sirs!!! J

[@ForgedEggs]

I like how just three short years ago Rob had a three rotor jacked from Area 51, now there's s 12 rotor sitting here, the hell did that come from?!

[@lexus_offroad_adventures]

Rob in 10 years: “I Built a 24 Rotor, 6-wheel drive RX-7”

[@JohnWiku]

This engine is the start of flying cars 😂😂😂

[@johndeveloper3203]

Don’t forget FD rx7😅…

[@G_Ozare]

This just broke my brain in half. I'm honestly speechless. Just when you think you've seen everything the internet has to offer this comes along. I'm so f**king stoked to see what Rob does with this monstrosity.

[@a-wale6376]

Smh. I know right. Whole thing literally took my breath away...

[@Avetho]

I was flabbergasted when I saw a video of this monster many years ago. Amazing piece of engineering.

[@sunilalwis3988]

It is good to see the assembly work and starting proceeded.

[@jerrysanchez5453]

The machining on that engine is crazy.what a legend

[@Hyperious_in_the_air]

Rob going full kid in a candy store this entire vid, lol. Don't blame him, that engine is legit one of the most beautiful pieces of CNC engineering I've ever seen.

[@dieseldan420ca]

7:03 This engine needs a reverse rotation turbo to keep its symmetry if it ever gets boost.

[@jamesm.8392]

Rob I am as excited as you are to see this and can't imagine what the possibilities are. Not to mention the Absolute Solid Brilliant Design and Work of Art Gorgeous Appearance. You are very . . . very lucky to have Tyson share this with you. I look forward to the videos that will follow, and I have subscribed. WoW.

[@jonathangreen4958]

AMAZING…I’ve followed you, for years…this project…like nothing else, ANYONE…has ever done!!! Insane…but as a team…you will pull it off! 👍

[@nikki5399]

The amount of engineering he put into this is mind blowing.

[@nate8930]

Code name: Mikey.. 'j3333333wwsss j3333333333wwss'

[@olekaarvaag9405]

Finding the best tune for this sounds like a neverending nightmare. I'm so excited to see this come alive.

[@rognvaldrasbjrn3972]

This came up in my recommendations.. For once i am thankful to the algorithm. That is soooo beautiful

[@StreetRacingLifeStyle]

This is Glorious! Respect to the Big block configuration on a Rotary! Insane!

[@ZachsFishM57]

I saw this engine years ago... I was just in awe and still am. The fact he's brought it to y'all to make all the hrrrsprrr's is just incredible! Can't wait to see it fire up!

[@jacobm2625]

I’m leaving two comments here, but holy cow. This is such an incredible engine. I look forward to seeing everything come together and run this/next year. Really, really great. And you can tell the guy who made it is an engine building genius for sure.

[@tuna22lm]

OMG this is just amazingly mind blowing. I want see it being all put back together so I can hear it running, thank you for sharing this amazing rotary engine with us rotary engine fans and fans of yours.

[@nee3029]

There are several videos of the engine running, even though they are 9 years old.

[@ericrawson2909]

First video I have watched on this channel. Can't wait to see this fantastic engine run.

[@moron_with_a_voron]

i remember the video of this from 9 years ago with the 2 glasses of water and all ❤ we NEED a CAD model of this, this is a work of art and a once in a lifetime engine ❤ im a ongoing engineer (fascinated by machining , motors, cars, cnc machines and all that) and the work that went into this is enourmus, the thoughtprocess to the machining, 📈im inpressed to the moon

[@kai_444]

the cad file for ahura is ridiculous already, 14gbs 😭😂 but I agree a cad model of this engine would be epic.

[@winstonpratt604]

I'm kinda curious as to the Budget it had on the Engineering and Mfg side of it ... I'm guessing a Half Milly if not a bit more 🤔 😳 😬......????

[@harryneumann8304]

I actually get excited everytime I see anything Rob posts. By far my new favorite KZbin channel. I have been hooked since I saw the first 4 rotor video

[@vicmacarra]

Donde esta el 4 rotores

[@mundanestuff]

One of the most beautiful pieces of engineering I've ever seen. Just fascinating.

[@dougvanausdal3162]

I'm so looking forward to seeing the next video on this motor, you have my attention

[@smackout]

after many many years scratching my head with the minimal pics available of this beasty motor. i must say a BIG thank you for allowing us an inside peek at this monster motor :)

[@Tonkata-fo4ek]

There is only one question in my head, and that is: Will this fit in a MIATA??

[@viper7215]

i was looking for this comment hahaha

[@Christian-cz9bu]

Yeah and boat headers to pay homage to the original use...

[@Token_Black_Guy]

Probably

[@wheelermanis7089]

Only in an NC, weirdly

[@Matty.Hill_87]

​@@Token_Black_Guy definitely, just need a big enough hammer to clearance stuff 😂😂

[@stejealexander5747]

Been watching Rob Dahm from about 1000 subscribers, and always will

[@slcncr]

When it still sat in the van, my first thought was: "OMG, this is a piece of art". And then you said it too. And it is even a thing of beauty on the inside. Just WOW !

[@sixeight8683]

The most impressive engine I've ever seen. I can't wait to see what you guys can accomplish together
