12 Rotor Engine Running- Different Angles 

22 gallons per mile

Rx7 guys hands are busy in pants right now!

that starter motor is having the hardest day at work...

I remember watching this all those years ago and being absolutely captivated at the engineering and insanity that went into something like this. And now, many years later down the line, seeing this engine being disassembled and explained over on Rob's channel is surreal. You've said it yourself Tyson, this is an art piece. I can agree to that!

making a time machine or somethin?

Let's see what Rob Dahm can do with this puppy...

i want to see it in a car

Its amazing! I used to work with 12A's and 13B's and I know the potential of these engines. But this is a complete power house of an engine. Well done. I would like to hear more about it.

Looks great but should invest into a mega squirt efi setup (of possible) because the carb is so far away from the front that it has to be leaning out the front rotors.

This engine is simply a technological masterpiece, you have done well! I'm curious what rpm this wankel monster can roar to... guess it's time to check out your channel!

Mazda should've had you guys in charge of their R & D division ! I still can't believe they stopped production of their main Rotary instead of continuing to try and refine it.

I am not exactly a fan of rotaries, but this thing looks and sounds violent!

It's smoothness is remarkable. Congratulations!

I bet it's faster than Sanic

Bad ass engine, but mpg would literally be like 1.2 mpg. lol Nonetheless bad ass.

This is meant for a drag boat? Aw, and here I was hoping it'd go into a top fueler, it'd be insane to hear going...

I'm not a car or engine geek but that's a work art.

This thing looks like it could launch windows 98 or cut through time. Wow

I recall back in the 70's Mazda had in their commercials the slogan, "Piston engines goes 'Boing, boing, boing' but the Mazda goes 'Hmmmmm'." This rotary engine isn't going 'Hmmmm.'

Well... Fuck. My 12a isn't going to keep up with that now is it..? LOL!

sweet fucking jesus that craftsmanship.

Solid engine ;) I want to see this in any vehicle ASAP Please keep the videos coming

I love the engineering behind this but the best part is it doesn't sound like a rotary :-)

Just take my money and give me the engine

Well done guys awesome acheivement ,please let it actually go in some sort of machine

Adaptronic E1280S will be at your door soon!

Now you gotta go get an RX7 to put it in lol

So many rotors doesn’t even sound like a rotary engine.

Dyno run please!!

Are there gears on the end of the 2 E shafts of both sides connecting to a big E shaft in the middle? I'm quite interested in how this thing works.

Getting closer, well done, will be a beast once its up and running properly!

I would really love to see one of these engines mounted to a top fuel dragster frame. Holy crap. Put them up against one another if its making over 9k HP!!!

Stunning piece of engineering! Did you cast or machine your own parts?

Disliked. Not enough rotors - Just kidding! :D Love it! I hope that engine's going into a vehicle soon!

Water barely moved! That's some good machine work there!

That is a thing of beauty!! I see you're working on tuning the fuel delivery. . Once finished it will be insane! What sort of car will sport this sinister piece of work? Huge props on building know how good sir

"FrankenRotor" Damn.

I only see 10 pipes in the intake manifold, are there shared cylinders or something?

HOW MUCH POWER? O_O A 4 rotor makes like 400-500 easy. What does this do?!

That's not water... it's clear gelatin! :P Just kidding... Smooth engine. I noticed the three banks of rotors and that is very impressive. I'm curious how you tied all three rotor banks together into a single output shaft?

I like the state-of-the-art exhaust evacuation setup they have. Looks like something I'd do.

That's an awesome chromed up version of a rotary engine, I only see four exhaust pipes coming from it on one side so it would be a 4 rotor engine right? Or does it have three E shafts in a W configuration? It looks kind of like three 4 rotor engines put together side by side. Please show a diagram of how the engine is assembled.

I see there's only 10 pipes in the intake and 8 pipes in the exhaust. I'm very confused because this engine sounds more like a 10 or at least an 8 rotor

Nice work. Four banks explains the shortness of the block. The C111 engine was at least 2 feet long, maybe longer and that was 4 rotors. Couldn't imagine putting a 6-7 foot long engine in a 1970 FIAT 500. ;)

intake/exhaust look like they are designed for a boat?

Hello there, what's the configuration on this monstrosity!? What's your end game? How are you firing the ignition? Do you have 3 different independent crankshafts joined by a chain or something along those lines?

Complete ground-up design or based on Mazda's rotary ? I love seeing people actually deal with rotary , that's one interesting ICE !

DYYYYNO! DYYYNO! DYYYYNO! gimme da specs!!

YOU HAVE NO IDEA HOW LONG I'VE BEEN WAITING FOR THIS~~~~~~~!

Lol you was so eager to put this engine into life you just put a hole in the garage door for exhaust!

jesus fucking hell

That's a pretty expensive way to boil water...

Put this monster running on hydrogen and a turbo. You can forget about the P1 and all the fancy hybrids for the next 60 years.

No revs?

What's truly surprising is that for the first 1:09 when they were trying to get it running that no one die of CO poisoning. Because an engine puts out a lot of CO and in a confined space it really does not take long for the CO emissions to build up. That is why a "Garage Under house is dangerous. Because if you go out on a cold morning and don't open the garage door, that room will fill with enough CO to set a sensor of in only a few seconds to maybe a minuet depending upon leaks from bad seals around the garage door and so on. it is also advised that if you have one of those types of houses to shut the engine off and leave the garage door open for a few seconds before closing it. It is truly amazing how fast CO emissions build up in confined spaces! Be careful.

Its a shame the video doesn`t give you the real sound of it.

This engine with forced induction will be too much for any non nitro v8 in any category, hopefully we can see this play out within the next few years

Defiantly an "A++" for creativity and ingenuity, but, seams that he is having a hard time getting the thing to stay running. I am by no means an educated person when it comes to Rotary engines, but, I have to say that from what I have come to understand of the Rotary engine is...it's kind of like an inline engine. so to make one into what looks like a " V " configuration, what kind of engineering goes into taking an inline engine and making a mirror image or it on the other side then getting some sort of gear box that would take the two in line's and make them "come together" to work a " V " configuration and have it spin at the same rate as the Rotary's are? I know that there are 2 types of superchargers, a "Root style" that sits directly upon the engine intake manifold, like In Top Fuel. Or a Centrifugal device that uses gearing ratios to make it spin faster than the engine speed in order to build up pressure and those are mounted to either an existing bracket on the front of the engine and perhaps making you swap out your lower Crank pulley to accommodate the new item or some that say just get a bigger "serpentine belt" in order to make it work. Either way there is a set of gearing that is involved inside the S.C. that makes it work. So that is what intrigues me the most about this particular set up? How do you get those two to work together, and maybe that is the crux of the matter, that issue is what is holding this BEAST OF A ROTARY ENGINE FROM WANTING TO WORK PROPERLY? I would love to know how you did this Mr. Garvin, please tell me, unless you are under the "paten pending" process and that would prohibit you from "spilling the Proverbial Beans". LOL. Anyway, cool build man really cool, as I said I would love to know how you got those two to work "together" perhaps you could do some of that magic on Capital Hill! Lord know they NEED IT!!!!!!

wow there's hardly any vibration. definitely built with care.

12 rotors? Add 6 turbos to it lol. 1 per two rotors.

0:31 start!

Thats the way my cup of coffee looks in the morning.....

if you are too lazy to click on the new articles.....1400bhp N/A.......turbo it = 2400bhp...race gas + turn up the boost =3600bhp

It a Puerto Rican's dream !!!

What are they going to put that monster in

this thing sounds like its angry to be awake

Hey is the i s a Tvelve rotor wankel mounted like this Jesus how much hp does.this make and what Gearbox do you have to have and the price?

Fuel efficiency like " Look I am Volcano now"

this is 1 of the coolest engine i have seen on the net, when i look at this i see the rotary engine like a 3 cylinder engine and there are 12 so to me i see like a 36 Cylinder engine and i think that is kind of amazing

It must consume sooooooo much fuel. Probably 10 gallons to the mile.

I wonder if this can be applied for a turnkey replicas? The small size engine and tremendous power will be great for all replica enthusiasts around the world. Can I buy this engine for my lambo replica? How much if you do sell one?

I am confused theres no exh, int or combustion stroke some technically isnt say a 1.3 a 3.9?

It is awesome to see 12 Rotors engines that works, but what are you accomplishing in these era with several altered ways into the Hybrid future.

I see what you did. Interesting.

Awesome masterpiece this. Imagine timing this beast..... Holy f#ck that would be frustrating!

its pretty clear to see the intake manifold and the 2 exhaust manifolds ...... you goon lol

You have injectors directly into each combustion segment? What was the carb for?

someone really knows there stuff! thanx for the pic on the porting, post some pix or video if you decide to put down in a car would love to see that!

i wanna see it in a car

BRAP BRAP BRAP

Big yellow cat .. I'v watched this going on for a while now .. have you tried it in the cat yet

Well done, sir!

Here is the Autoweek article on it www.autoweek.com/article/20140225/CARNEWS01/140229886

TUUUUUUUURRRBBBBBBBBOOOOOOOOOO!

Nothing quite like a power stroke every 10 deg. Lol

I got 10 rotors? !0 pipes coming out for the exaust? Weird though... it looked like there was 10 pipes for the intake, but a couple more, looked like they where going to the crankshaft?

I don't understand how this is a 12 rotor? its way too short. is it two banks of six small wankles feeding a central crank?

Put that in a dune buggy or in a drag car with like a 100 mm turbo

twincharge it. *sigh* and melt everything, sadly.

i know it will run away from you theres a fix for that.,lol

It looks like it is set up for a boat, is it?

Can't wait to see how things ends!

Wow!!

upcoming Mazda RX9 2016

It's basically a giant Whipple charger. Put that in a RX-7 with an AWD kit and it's on like donkey kong

that is fantastic, I love the WANKEL!

Can it run on unleaded gas RON92 or RON97? If yes, how man hours before the next service? Or do you have a street legal version that can produce any where between 500hp - 800hp that can last more than 5 years or more?

RIP Headphone users

put motor in a big Cadillac :)
