Can a 4 rotor be use in city driving like if there is sudden traffic? Won't it get overheat?

Why are short crank 3 rotors not good for boost but 4 rotors can handle boost? they both have a intermediate plate machined for stationary gears

I have always LOVED everything about rotary engines like wankels. They really are in their own class of internal combustion engines. I especially LOVE 787B and other 4-rotors. I feel like they are truly in their own league. Your car is an amazing most unique artifacts in automotive history. I'm blessed having found out about you and your incredible "Iron Man -suit" even though only today. Thank GOD you got it back. ❤❤❤

Well at least you're rich and you you can replace most

Glad you found it not ment to happen it just happens same thing happened to me on the highway went to get tire came back and my trailer was broken into and stole my brand new 10000.dollar motor never was found f

Thanks for the content, love learning as much as I could about these rotary engines

Does anyone know the song being played at the end of the video?

Would ya look at that Nice street legal and imsa loud

i heard the engine was fro impossiblerx7 what happened to the engine

This car is so fucking sick!

God bless Amen 🙏

Nice kw

What type of ECU are you running in your current 4 rotor racecar?

See you this weekend!

Best wishes from the german rotorheads

Cool old KW project.

Still watching a masterpiece in 2024

Why did you not do the whole engine out of billet would the middle stationary gears crack easier because they are cast

My dream a datsun 510 with this r26b 10k rpm.. heaven.

Daaam...having the knowledge and ability of building a rotory engine of 2,4,5,6 rotors is an art and gotta be gifted of souuu much skillz...i wud of rebuilted my engine and i have to depend on a mechanic to do this rebuild on my favorite car.🫤🫤

I’m amazed at how much is running through that transaxle! You can definitely see why they’re Uber expensive!

To make the rotary work, could you make a 'drop-adapter plate'? Mazda bolt circle on one side, Xtrac on the other, with quick change drop gear between the 2 sides.

Very simple design the way things should be

So much knowlege! Your amazing logan keep the good content comin 🤘

Is that a 386 xtrac? 5 or 6speed?

Super cool!

You need to start your vids with an intro , who you are , what the vid will be about , etc.

Good stuff

If you use a 12a intermedia iron you can solve the intake side port problem?

Extremely clean and well done.

Very cool! I take my son to AMA vintage days at mid ohio. Maybe one day I can take the rx5 around that track.

You mentioned that even if something bad happens, that it is for a reason. I try to live with that in my mind, but emotions get the best of me most times. I have to say how you handled the situation is very inspiring to me. At the beginning of your story, I was thinking of how i would have overreacted to blowing 2 tires on the trailer, but look how it worked in your favor. Glad you recovered what you did.

Why does scoots 4 rotor have that smooth high rpm 787b sound while yours sounds similar but kinda raspier like a v8 f1? is this only to do with the exhaust?

Pretty! All that advanced work you do, and here in SC I can't even find a tuner that works on rotaries.

Fantastic info. Out of curisoty do you prefer the single or the two piece ceramic seals?

Awesome Logan.

I've been looking at the evolution of Defined Autoworks for the last 10 years or so, always impressed by the creative solutions developped for engine and chassis tech. Props on the work Logan! By wanting to emulate the R26B, were there any plans on creating a variable length intake trumpet system to extend the torque curve? What do you think of Judd's twin roller barrel throttle bodies on their V10 race engines vs the slide throttle? I've read it can be "easier" to get decent drivability from them and less chance of sticking, although they are a bit heavier than slides or butterflies. And I've always wondered if exhaust power valves (like on modern 2-stroke sleds) would be beneficial on a rotary... Arctic Cat's latest 858 C-TEC2 has an ingenious servo-actuated power valve system. The idea would be to somewhat control the amount of overlap on a full PP rotary to get more torque and response on the low-end and make it a bit more streetable (might be useless for a racecar, but curious nonetheless). Might make for an overly complex exhaust sleeve, but I haven't seen anything like this tried on a rotary through 60 years of patents. Cheers mate!

Everyone talks about power, but.. how much torque could a 26B engine make?

Superb video, Logan!

What did mazda do that was different 30 years ago to make so much power on the Le Mans 26b engine in the 787b?

I like the V-band exhaust and love the slide throttle. Im surprised that such a small dry sump works but it is a small motor overall. Do you have figures on the coolant temp differences between your system and lets say a "stock" 4 rotor coolant system?

Good tech info

That center cooling is really smart.

Thanks for sharing. Great video!

Impressive work Logan! The 13B you built for 10:21 me years ago was still running perfect. Money well spent. Thank you

What about a Six Rotor?

Awesome Christmas present! I really love this type of video, very interesting. Thanks for sharing your knowledge!

Thoughts on Dahm's (or really the Curran Brother's) custom irons that utilize a tungsten coating on the face of the iron? He seemed to have success with it, just wanted your thoughts. Wonderful video.

lawless america , cia and fbi have their attention if u say play with your ass is no good, for them is a crime , its incredible how the military want dictated everything

I wish I had money. So I could have Logan customize my rotary car.
