You can hear the sincerity in Simon's voice when he thanks his entire team and sponsors for making everything come together. He's a class act. I miss both my RX-7's but mostly the 79.
I'm an old rotary engine specialist from the 70s. Thank you for the detail and conversation in this video. It really brought me back to my days with Mazda.
What a legend this bloke is. Polite and calmly spoken, happy to share his knowledge and a few little tricks of the trade, even goes out of his way to be as relateable as possible.
I bought a new RX2 in 1973. It was a screamer for 2 rotors. It was billed as an economy car. The best gas mileage I got was 13.5 MPG. I severely abused that engine and it never busted. Slipped my foot of the clutch at 7,000 RPM. And occasionally miss shifted to third and hit 11,000 RPM. It never broke. But the clutch wore out several times. As did the skinny 13 inch tires.
I was just thinking the same exact thing as I was watching this video. I've built a handful of racecars and did all the engine assembly except for the things that I needed the machine shop for. What an amazingly simple setup!!!
I could listen to that engine builder all day, he has a calmness about him. He would be an excellent coach and is an artist at his craft. Reminds me of the Bob Ross of engine building, minus the wild hair. This guy does excellent work!
You can tell how much profit margin and room for competition there is by how the shop looks. If it looks like a doctor's office they are price gouging insanely and an open market for easy competition!
@@illbeyourmonster3591 Fallacy! First you have to clean up the shed, which in your case may take up to a week. And then you can do the work in a week, which now, with all your gang, takes a month. As long as you keep thinking the way you are doing now, you will be a poor bastard. Sorry! translated with Google
Great video! If possible you should get a tour of BilletPro to see how it's all made ! Absolutely top content ! What cameras did you use for this video?
As a former 1980 rx7 road race crew chief, who has torn down and rebuilt a bunch of 12as, this video is inspiring, and that engine looks freaking amazing. Nice work!
Nice video - it's watching an artist at work. Even the explanations are humble and you can tell they're from experience. Really enjoying that he's in a clean workshop but doesn't wear gloves.. that's the real guru business right there
I loved my 13b rx3 I had as my first car. Damm I wish I still had that little bastard. Makes me so happy to see a craftsman putting so much love into his work
19:24 - Both the materials science and CAD-CAM driven CNC machine tools caught up to the design potential of what was envisioned when this type of rotary engine was developed?
Recently Scotty did a documentary on the Mazda motors company and his TH-cam channel is the most followed on TH-cam for car repair. An he explained all that information.
Such a beautiful engine. I hope whoever it goes to truly enjoys it... I've always personally wanted a 3 rotor with either high compression and low boost or low compression and all the Boost. But they're made of unobtainium for us mere commoners.
Good prices compared to PPRE, It would've been cool to hear his opinion on machined/balanced rotors considering Mazda doesn't have the best tolerances from factory..
Love listening to this master of his craft, fulfilled life of doing what he loves. For all the rotary guys in the comment section, I came from the liquid piston engine to this. How come nobody sized that thing up? Seems like the next big step in the evolution of rotary engines. Would love to hear your opinions on that. If you don’t know just TH-cam it there is more and more content coming up.
Theres a side here in America working on a full billet engine. Billet housings & billet roters, I'm excited to see how it works out with the billet roters.
The Chevy XP-882 Aerovette prototype had a four-rotor Wankel rotary engine installed for the 1973 Paris Motor Show. They cancelled the engine because of low reliability and high fuel consumption. I wonder if they got it right this time. That would look fantastic in the rear of a car like the Aerovette.
How does a custom twin rotor compare to a standard 13B engine in terms of longevity? I used to own rotaries in the past and the apex seals going at 50K mileage for 13B RX3 was the issue. Do the unbreakable apex seals allow more kilometres from the engine?
damm thats some sexy engineering. The rotary has so many pluses for motorsports. Having said that I remember back when the first rx-7's came out and a young bloke in the motorcycle club got one, all us teenagers came and drooled over it and my older sister came over and said" nice car why did you get a sheila stick". It was a bloody auto lol.
Whats it weigh and how much power NA and or turbo. Been thinking this idea for while for an experimental aircraft application. Obviously need a gear box to turn propeller down to 3-5k. But stack rotor and stator after another.
Is there a limit to the number of rotors that can be used? I appreciate that the engine bay size can be a limiting factor, but as that is due to the firewall there seems little to little to prevent the firewall being changed to accomodate anything with 8/10/12 rotors, presumably the next issue would be the gearbox size/position? One other thing that comes to mind would be if it was possible to build a couple of 4/6 rotors then have them run side by side and with a connector that takes the double bank output and combines it into one shaft as it goes to the gearbox. I wouldn’t be at all surprised if I’m just coming out with stupid ideas but as I’m showing, I’m not much of an engineer, but I do have some ideas/questions/dreams that I’d enjoy hearing what real engineers might think. PS - that four rotor looks gorgeous, but I must admit that I’m partial to some nicely anodised parts as well.
there probably isn;t but consideration has to be taken on how the oil flows, cooling etc..& that point has to be designed a bit different. but maybe 2x2 could be done inline .
PAC performance does full billet, rotors, housing, plates. They're testing them in their drag cars. Last time I heard a specific race team has requested for the package to start racing with it.
This has been my dream job since i was a little kid. Hope to one day work and build engines like this. Right now i go to a mechanic school in Norway and after the summer i am going to have 2 years of kinda school but i am out in a actual mechincs shop. After those 2 years i am probebly going to look for a job like this. Dose enybody have eny tips for me in thees coments?
Awesome engine. I'm kind of surprised that I've never seen a bottom block girdle for rotary engines(doesn't mean they don't exist) that sandwiches between the block and the oil pan to limit core twisting. I'm hoping that when they have to make billet housings(ouch $$$$) they might make a custom setup that utilizes thicker studs and maybe external dowels, etc to keep the "block" from twisting and stable more. May not be a problem.with billet end plates being stronger but......Lastly are you looking into custom renesis plates that are thicker to add meat to the exhaust ports/allow for a possible water jacket between them? Other than a higher compression ratio from mazda, that seems to be the weak point of that motor(other than cast iron plates) for turbocharging it. I know that would necessitate a custom eccentric shaft but that's doable. Then you'd have what would probably be a really awesome 13b-renT
How much would this engine cost? I'm looking for an engine for my next build. Also, what type of transmission could I mate it to for a mid-engine setup? Was going to go with a V8, but this looks interesting to say the least. Thank you.
I've seen quite a couple of builds now. Can't get enough of these vids. Builds with standard components, machined standard component. I've seen billet blocks, specially build crankshaft. All kinds of bespoke parts, but the rotors used are always (machined) standard parts. Why is that? This build looks like it's compromised (?) by 9.7 - 1 compression rotors. Aren't there any billet, lightweight, high compression rotors being made by some specialist?
Just thinking what about a center bearing that is mounted in the center to help support the crank, just like the V8 supercars with the bearings for the main crank, instead of the traditional bearing caps for the crank if you get my drift. :)
I must be the only guy in the world that has a lot of trouble wrapping my mind around exactly how these engines work completely. Man, they are beautiful in their simplicity.

The one at the rotissery chicken shop! Just keeps spinnin' lol 🤣
@Mcgoogoo Damn! You beat me to it. I was going to say exactly the same thing!
My ultimate favourite rotary engine is the one that has had an LS swap! FTW!
You can hear the sincerity in Simon's voice when he thanks his entire team and sponsors for making everything come together. He's a class act. I miss both my RX-7's but mostly the 79.
Don't miss mine having rebuilt the engine twice.
I absolutely love how Simon is just straight up honest and not afraid to give his opinion on things. Love the discussions you guys had on this video.
I'm an old rotary engine specialist from the 70s. Thank you for the detail and conversation in this video. It really brought me back to my days with Mazda.
Got to give you credit Fullboost, you get some of the nicest people who are more than happy to share their wealth of knowledge. Genuine people.
What a legend this bloke is. Polite and calmly spoken, happy to share his knowledge and a few little tricks of the trade, even goes out of his way to be as relateable as possible.
I felt the same way
Great built, however, I'd love to see them running after the built is completed. That would be the icing on the cake :0)
I have a running 4 rotor on my channel, it’s wild!

I love how beautifully simple rotaries are. No valves, gears or pushrods; just block, crank and rotors.

"There's not too many cars you're gonna fit 6 rotors in..."
Anything that can fit a 2K Barra will fit a 6 rotor, or atleast come very close. 😛
Don't think there would be much difference.
He was refering to cars people might want to own. 🤣🔥🔥👉
@@fullboost So a Renault is out of the question? 🤣👍
@ChrisHallett83 If they can fit a 6 rotor in a damn RX4 then it will fit anywhere a 2K Barra can. 😎👍
@@MafiaboysWorld Anything fits if you drop it from high enough. And they prolly cut out most of the firewall for the rx4
As of 12/2020 mazda announced that they will be making new parts for rx7s again.
Simon would be a good man to work alongside in the automotive industry. Loads of knowledge, passion for his craft and patience to teach
Everytime i see pro rotary build videos, it look like they r doing it in a doctors office.
We used to stack them together on empty 35 gallon drums outside in the sun

Thanks for the update and video, as always a pleasure seeing Simon put a rotary together. Memories of my rotaries I owned, rx2 rx4 and 5.
im simple I have an Rx7, I like Rx7's and rotaries!! If I see a rotary video, I click
Simon is a top bloke - thanks for sharing.... Nice tidy edit too :)
I'm really happy to watch him assemble rotary engines, thanks for sharing!
Nice video - it's watching an artist at work. Even the explanations are humble and you can tell they're from experience. Really enjoying that he's in a clean workshop but doesn't wear gloves.. that's the real guru business right there
I’m so happy to see people still exploring these smooth compact powerful emission engines ..fascinating
I loved my 13b rx3 I had as my first car. Damm I wish I still had that little bastard. Makes me so happy to see a craftsman putting so much love into his work
What a work of art the Billet 26B is, no mention of the matching price tag to match 🔥
30-40k my guess
@@chunkycheese73 100k
I'm a V8 type of guy, but these engines are so interesting. Billet aluminum always looks good. Awesome looking engine!!!
Would love to see a 10a build. Always been curious and super rare now.
👍🏽
I've been binge watching every video 4 rotor and 787 related. Am I going crazy?
I’m not even into rotaries but I feel like he is the man to talk to.
A doritos commercial was played right before this video started.... I've never seen a more appropriately timed advertisement in my entire life.
I know little about rotary engines, however that was a good presentation. Nice Work.

Not really , people blow that same amount making forged internals
You can tell he's a master builder, he loves what he does...
This makes me want to revisit the dark side.
As someone who saw what you did with the HB Cosmo back in the day Lance...DO IT DO IT DO IT DO IT DO IT DO IT!! 😈👍😁
Don't do it Lance!
I don't know what you did with the HB Cosmo, but I echo MafiaboysWorld, Do it!
We have a hybrid lightside now
Please show the 10a build! That would be an awesome video.
Man there are some brilliant people out there and your one of them just awesome
Another awesome video boys at a quick guess if the billet 3 rotor cost $45k aud to build this 4 rotor would be around $60k aud to build
A lot of Doritos yes.
Good prices compared to PPRE, It would've been cool to hear his opinion on machined/balanced rotors considering Mazda doesn't have the best tolerances from factory..
If you watch the 3 rotor video we did Simon touches on that. 👍
@@fullboost It looks like Pringles.
I love Australian ingenuity. Keep up the good work.

*_There was actually a 12 rotor engine built._*
Not too much people know about it but it is sick!
Boost fixes everything i agree😂😂 Greetings from South Africa. Im installing a 13B in my Fiat x19. Can't wait to braaaaappp
Theres a side here in America working on a full billet engine. Billet housings & billet roters, I'm excited to see how it works out with the billet roters.
Yes its good to see people are going to be making these engine parts for a long time to come.
Wow stunning I been introduced to rotary engines on Thursday and haven’t stopped thinking about her I want rotary in my life.🥰
10A would be an interesting one for sure! Not a rotor man but love the in depth content!
Is there any way to track where this Engine ended up? pics/ vids/ links etc.. Beautiful engine and wonderful video.
no bullshit just pure rotary talk, big ups boys
This guy is a legend 😊
I love this builder. Simon has it together,. I would love to spend a day with this guy.
Beautiful engineering, beautiful machine work!!!

I use to have a 87 RX7, and I am impressed. Subscribed.
Funny looking packet of chips. I dig it. It still blows my mind, that you can just keep stacking them together.
Quad stacked Billet Dorito yes please. I like mine spicy👍😂
4:22 "What's that part you dropping in?"
me: THE DORITO!!😎

had an RX-7 with a 13B... 22 MPG, easy oil change, filter on top of the engine, and easy tune up.... had it 8 years.... should have kept it.......
Unbelievable thank uou for the video it was a pleasure to view !
Its so cool to see engines being built 😎👍🏼
WOW 13J R26B 4 ROTORS ROTARY ENGINE BY BILLET PRO SO SWEET ENT
This is the 5th time I had watched this video. I can't get enough. If I win a lottery...
Keen to see the 10a build now
He speaks so calmly I love it😂
4 rotor??? LET'S GO!! MORE 4 ROTORRRS ON HE STREETSS THE BETTER LIFE IS
damm thats some sexy engineering. The rotary has so many pluses for motorsports.

Well done and fair play fellas.
Rotaries are so simple and so beautiful.
That will be an outstanding little screamer.
Amazing machine work. Billet pro is amazing.
What about pricing? Would love to know the cost of the engine.... and real figures of getting it running reliably in say, an FC3S...
Man, Simon seems like such a cool dude
iv got the wrench, 1976 , started my time. . bloody good unit, its part of me now,
I got a Warren and Brown tension wrench in 1979.

Now I wana see this going into a RWD RX7. Its gona be a real racing machine!
can't wait to have mine built 👍👍
That is a piece of art. Im afraid to even venture a guess on what that engine sells for
Wonder when they'll start making the rotor housing as well and not just the plates?
PAC performance does full billet, rotors, housing, plates. They're testing them in their drag cars. Last time I heard a specific race team has requested for the package to start racing with it.
A beautiful work of art.
I saw a video where the shapes of the rotor and the housing are reversed, with ignition at the triangle corners.

But I really want this guy to build me one anyway!
The truth is, aside from length design parameters, there is NO LIMIT as to how many rotors can be stacked together.
Love me some aviation sealant.. used it for years without problems
Me too, it's a staple in my workshop.

Your favorite word in this video is "yeah" . For this friends made a drinking game with me.... Was very funny xD
Can u show us the assembly of the 10A out of interest, please?
Very neat and clean setup
Just thinking what about a center bearing that is mounted in the center to help support the crank, just like the V8 supercars with the bearings for the main crank, instead of the traditional bearing caps for the crank if you get my drift. :)
everybody gangsta till rob dahm pulls up in a turbo billet 6 rotor lambo diablo with awd
Im quite not understanding how the oil lubricates inside the chamber.. on those seels acting as pistol rings
Question:
Do Rotary engines suffer from combustion Cavitation.
Has anyone dimpled the combustion chamber of the rotor.
