700hp Billet 4 rotor R26B *Clone* built in 5 mins! Mazda Rx7 Defined Autoworks Pt. 1!!

[@juniorschouten3448]

This guy is a legend! I want this engine for my fd3s. Rotary life will never be the same with this engine

[@GTORx7]

I'm no legend, but appreciate the thought!

[@RIBZOH]

The photo with Mr amemiya at the end is very special ! Amazing work.

[@c22tch]

At this point do we need Mazda to come out with a new rotary engine or do we just need a new chassis for all of this new billet goodness ?!!! 😝😝

[@connoisseuroftigolbitts]

A new rotary engine that runs on gas and electricity should definitely be in the works 👍

[@QuantumPlaysOfficial]

Maybe as a hybrid Rx8 called The Rx8 FE

[@jacobwebb8818]

@@QuantumPlaysOfficial FE? Iron? That would be Fe

[@mmwosu]

Plenty of chassis out there that can accept a rotary since they’re so tiny. I still wouldn’t turn down an RX7 reboot from Mazda though, too bad the engine would never pass modern emissions standards 😕

[@connoisseuroftigolbitts]

Keepin the rotary community alive! Love this man 👍

Accidentally read the title as "4 Rotor *RB26* Clone" and went hmm for a minute

[@jacobwebb8818]

Had to look 3 times myself

[@rotaryperfection]

Logan T-von here! Pretty ingenious with the center housing coolant mod. I can easily see the coolant traveling front and rear from the center for even heat exchange. Seems this mod more closely keeps the housing temps even front to rear.

[@GTORx7]

Thanks man, I just copied Mazda. Anxious to see how it works in his race car

Not even! Logan been building 4 rotors long before Rob got the itch.

@@efini_fc4276 REALLY...?! Then what are they doing about it...??

[@efini_fc4276]

@@bryanp4827 The only thing I will say about them producing an RE right now is I'd like to see crate engines from them, built not for the street. But beyond that... They've accomplished and produced more than any of the top 10 rotary shops have ever done for the engine, put together... And a large amount of those shops wouldn't even be around without the Mazda-designed models in the first place. If emissions weren't so tight, the engineering would be different and there would be plenty more of these engines filled with even more love, with a Mazda branding. I these guys don't build race cars more than they do passenger vehicles.

[@Baukevandijk]

@@bryanp4827 They have been developing rotaries since the cosmo, and are still developing it to this day. Its just that emissions have to be lowered first, but they believe in it like a religion, its just insanely difficult if possible at all to develop an economicaly sensible rotary engine. They sort of got their will now as they announced that their new Electric Mx30 Will get a rotary range extender. But to repeat it once again. Mazda is still obsessed with their rotary engine, its just that it takes hella time to develop one that will work in the modern world. I do however agree that they can also just build race rotarys. however with company's like billet out there, whats the point.. They don't have the manufacturing capacity anyway

[@MrDelsoleg11]

They're the reason you even have the opportunity to love them in the first place lol at the end of the day mazda is a business and they need to sustain themselves, while rotary powered cars are there claim to fame in the performance world in all practicality reciprocating engines are what pays the bills and gives them the opportunity to be able to design new generation rotary engines. Let's face it rotorys aren't the most emission friendly engines and trying to produce one for the mass market in this day in age is hard. Hopefully they do start selling another rotary powered car in the near future, but if they don't at least they left us with great platforms and engine designs to keep improving on.

[@Skyrexx7]

Thanks Logan for sharing your amazing work!

[@term0s]

One question. How much? Wanna R26B in my project...

[@H8er-Maker]

Sweet video, I suppose if we can't hear it purr the music will do. All of those rotors are 1 off billet pieces milled in CNC machine in house? That's talent. Do you have more than 1 4 - rotor ready to race?

[@GTORx7]

Thanks! Just cnc lightened rotors, not fully from scratch. I don't have any 4-rotors on the shelf ready, too much overhead cost.

[@Dr.Altezza]

[@JB-sv5pr]

Bro you are always pushing the limits love it very interesting differences between the legend 4 rotor vs most home brew pancake 26bz love the rota for life aloha from Hawaii amazing content !

[@danacook9615]

Question, are the rotors on a 4 rotor set 180 degrees apart from each other? And I was trying to tell from watching the build how they are staggered. Can you expand on that for me please? Also, I have a perfectly running '04 RX8 that I love. How much to put in a deluxe 3 rotor motor, upgraded clutch, and transmission? If I brought the car to you.

[@GTORx7]

On the eccentric shaft itself rotor 1 and 2 are 180 degrees, 2 and 3 are 90 degrees, then 3 and 4 are 180 degrees. This works out to each rotor firing every 90 degrees. 20b full swap usually costs $35-40,000

[@balljointfd3s]

Correct me if I'm wrong, but you bored two massive holes in the center iron of a 26B so that you could cool the front and back two rotors of the engine separately and more efficiently?

[@jnmason6283]

Any plans on having the running surfaces coated in cermet like the R26B?

[@WanderingSword]

similar to how I make a 4 layer peanut butter jelly sandwich

[@JoshRex7ven]

the R26B had a triple spark plug setup. are you just using the standard leading and trailing?

[@HK45Mark23]

The final count down.

[@dalaw6600]

So this is what powers the ships in Starwars

[@flexgado249]

Where is the adjustable length Intake trumpets? That the R26B had.

yeap that's Mr Amemiya!!!!

Are rotarys reliable and inexpensive I think I want one myself possibly

[@countryjoe3551]

I want to hear it run....😎😎😎

[@maaduece5132]

do you have to set the rotor in a set poistion like a firing order when you assemble it

[@GTORx7]

Yes indeed they do. A good observation. A 4 rotor clocks each rotor 90 degrees apart, and fires on the same events per crank rotation as a v8 actually.

[@babisotonggg]

Fuhh 🤩

[@caluzzucarrazzi5549]

man this must have been a 100k motor... but I want one so bad, I'm 23 so mark my words, soon enough

[@richmonsmith9308]

No locktite on the crankshaft cog pulley? Or the retainer? Or did you just not show that on the video? Personally for me anything which spins regardless of direction gets blue loctite....jus imo.

@@GTORx7 Awesome. I'm always making parts for side projects on the manual machines at work, lots of fun. What do you think of getting into rotors as someone who's never touched them?

That is one of the scavenge tubes for pulling oil out to the external drysump oil pump.

[@muhammadabrooramrullah996]

How much that engine cost? ((((:

[@balljointfd3s]

Wait wait wait... wtf.... How does this coolant system even work? Wouldn't the coolant just create super hot pockets in the right front and left front of the engine? I know how the coolant passages in rotaries move from right to left with the rear iron making the turn for the coolant in the back. Please explain to me how this works. Hell, I'll pay you for the answer.

[@GTORx7]

Yes, coolant enters the center billet plate, and branches out to the front and rear on the hot side of the motor (same passages as factory) then the rear and front make the turn to the other side and flow back towards the center plate again. Once they join together the flow comes out on top. It has to be setup exactly even flow. This was a prototype. Since then this has been on the dyno with many temp sensors, all of which read completely even temperature.

[@alleydee9226]

asking to see it being built most rotor mechanics won't even tell you much nevertheless let you watch a rebuild

[@coryfout3687]
