Basically this is the best rotor engine car ever made , I've never been so excited for a project before , i know this man been busy considering how much little he's been uploading .
Wow, thanks!
It's as though he saved up all his might and brought a veritable Thor's hammer down instead of pissing around with lesser pursuits.
We need Rob Dahm and David to combine forces on the 12 rotor for the ultimate rotory project 🤯
@TheBCninja I'd agree... then think there may have some conflict in design/development methodology. Hopefully on a single project in the future to take on the world!
@@TheBCninja A Rob and David collab would be cool. They have two different flavors of the tism so David could maintain the long term vision while Rob does more of the engineering
I have such a hard time believing he has only 121k subs.....his car is a masterpiece and thoughtfully engineered. BOOST HIM!!!
His subs will double when it's completed then again once it's on track. I think he's making a future headache for himself literally always opting for his vision NEVER opting for cost effective or convenience in design. He goes full exotic bespoke first lol. It'll be sweet as fuck and probably lands him a high paying job working for Pagani or something so 🤷♂️
This build is on another stratosphere. One day all of car youtube brains will collectively explode when this goes viral. Bravo my friend
The amount of information in that brain of yours is crazy, detail packed information discussed for 30+ minutes without a pause, no notes. You are truly an artisan of this era.
When are you and Rob Dahm going to meet and discuss rotary engines ? I was watching your videos years ago then you must of took a break because I ended up following Rob Dahm and been watching him for years because of the similar videos. Very passionate about every final detail and super in-depth explanation of everything and the process it took and you're super humble and give respect to everyone who's helped you and been apart of the project along the way. Looking forward to more from you can't wait too hear this thing running and what you're doing for ECU and PDM controls. Very insightful learned alot indirectly from just watching over the years. That turbo is insane but they've come out with some even better stuff recently, E-gates, twin scroll, better bearings, turbo speed sensors. I bet you'll go with something different than what is in this video?
Need this
I'm so absolutely excited I can't wait to see this thing moving at speed, it already looks like it's moving 200mph.
What a Masterpiece. Beautiful. Amazing. Wonderful. Powerful. Unique.
I’ve followed you for years. Firstly, your content and articulation show a passion and real engineering prowess. Secondly, the chassis is golden. Well thought out.
I'm convinced this man could design and build a space shuttle if he chose to.
This level of detail is whats satisfying to see. Especially the regulated oil pumps, never would've thought of this
Wow, I'm drooling over this car! LOl Can't wait to see and hear run once completed! Amazing attention to detail David..
I really enjoy how meticulous and precise you are with everything dude. You really are creating a piece of art work and a badass car!
Bro is living my childhood dream. I've wanted to put a rotary in a superlite since highschool. I'm excited to see him have fun it it when he's finished.
Can't wait to hear it run.
Fantastic levels of detail, totally uncompromising and absolutely obsessive. Brilliant build and loving every video
The drive to get something like this car accomplished cannot go unnoticed. This build is incredible!
Great job Dave! I absolutely love the detail in which you explain things. You are really good at teaching and maximizing the value delivered to you audience. What was novel is just this afternoon I had mentioned to a friend who rents half of our shop that I had been compiling and documenting various pulley and drive systems for use when we manufacture dry sump/compressor systems for some of the oddball engines we have. I with great enthusiasm explained that I had discovered HTD belts and pulleys and that they would be a good way to standardize as much as we can.
David, you are creating not only a precision built machine but also a work of automotive artwork bro 👌
Love your approach to this project
This has to be one of the best project cars on the world,never ceases to amaze me how much of atention to detail you put ,keep working hard!
I think this is great. Can’t wait to hear this thing fly on the track.
That is one hell of a video. Sooooo much to think about. You have a amazing mind. Love from New Zealand as always :)
Can’t wait to see a video of the work being done !
I'm loving this series and your straight to the point approach
Fantastic. So detailed, so much planning and so well explained.
👍👏👏👏
I am glad this came across my recommended videos! SUBSCRIBED!
Sir this is a beautiful build, I am impressed with all the details thought out through this beautiful car.
This is a beautiful masterpiece. Wow
Passion and pride in your work 🙌
Personally speaking, not being too knowledgeable on things like this myself, I love videos such as this where it's such detail and explanation and you can just feel passion behind his speaking. A video that's documenting the process and care behind everything instead of a video that just pops up with it all fired up like a bat out of hell. Both videos are nice but growing up watching "How it's made", this kind of pulls at me more. Can't wait to see it scream man.
Holly crap!!! Crazy fabrication 🤯
Pretty much the best goddam RUclips channel in the history of human life
Great build, goes without saying. Thanks for the explanation on the water vs meth injection that was interesting to learn. Your build seems to be very detail oriented. Thank you for the in depth review of the componets. Love nerding out on car build porn like this. Keep the vids coming. Cheers
Nicely explained. You got a a sub.
Great project and car. Awesome to see the dedication as well as the details. Hopefully the car won't be crashed at all even it's a race car.
You definitely give #builtnotbought a higher meaning!
documentary style videos are my favourite.
And this is the future 🩵 finally someone revived the rotary
bro this car is so cool, great work!
So much knowledge 🤯
This is just awesome!
Subbed.
Hi David, thank you for another fascinating video into this amazing project. I wanted to ask if you'd be willing to share the brand/model of the CDI coils as well as the external voltage regulator by any chance? I'm playing with ignition systems on a 13B and would like to try the coils you are using and compare to my IGN1A's. Also the external reg idea is fantastic, not only for heat management but like you said, voltage choice.👍
Thank you, fueltech CDI and coils, and I haven't yet chosen the regulator!
thank you for the reply David, much appreciated@@dzmazzei
Cool idea on the alternator. Classic VW started with a generator with an external regulator then eventually moved to an internal regulator aka alternator.
Really nice work 👏🏿
"He said 'elongated shafts' he, hehe" **Beavis laugh**
With all the meticulous precision throughout this build, I'll admit I was shocked by the width of the clocking mark on the pulley.
Looks like an LMP1/2/3. I remember reading an article that an SLC is able to keep up with an Audi R8 GT3. That s very good considering the costs for an R8 GT3, a little over half a million dollars. I prefer the DIY, fabricate your own route. A lot more fun than just a buy and drive/race journey. Awesome awesome build ❤
this feels like what a meeting at the Mazda C suite was like when they were building the 787B back in the day.
This build is crazzzzy
You really gotta have a word with your sound guy
I am the sound guy
@@dzmazzei the video and audio are way out of sync. It's not quite as noticeable as the video goes on but definitely still there.
Yeah it's noticeably out of sync
He is the man come on dude 😅
One day whens it's more important to me I will invest in better equipment but for now I'm happy with it!
I almost choked looking at the size of that turbocharger core. My God, if this car can do half of what I expect, this is going to be car porn that's so good, it could get banned.
Thank you
Dapper asf. When we look back on these videos in 30 years time when the earth is not in smouldering ruin and the next ice age impending we will say damn he looked good.
🤣🤣🤣🤣🤣💯💯
Very interesting ep. 🤙
Have you looked into a digital belt tension meter. Used in precision industrial applications.
Is it possible to do time lapses of the assembly of the car?
Did you consider an external crankshaft support bearing to take the belt loads? You’ll still have the drive tension from your loads even without the additional preload tension for friction.
Yes it is something we are currently considering, replacing the front guide bolt with a shoulder bolt that holds a ball bearing, pressed into a plate that ties into the oil pan / front cover. however it would require extreme accuracy in bracket placement and Clearence from fuel tank is limited. I am on the fence as to whether it's truly necessary, and if trying to add more support would actually create more risk from more potential things that could fail
Re: Water line touching the core support, considered vibrations eating into the hose? Maybe some material between the two so they don’t rub and degrade?
As a small time backyard mechanic, I feel like those belts were a bit loose. They will no doubt loosen up a bit with heat and use, and I'd hate to see one fly off and rip things apart. Personally I'd be going with an idler. Love watching the build, thanks for documenting it!
Are you using NA Miata door handles?
Most of the tension on the the drive and driven comes from the work not the tensioner. You could look at belt tension as a static load, the work is where the real tension occurs. Moving the alternator and pump away on Jack shafts is a great idea and offsets the load from radial to axial which protects their own bearings.
This is gonna be another unicorn 🦄 bro 💯
I don't know much about a rotary engine but is there a way to make it where you could monitor oil pressure in each rotor?
You’ll be amazed at how tight those 8mm belts get when they get some heat in them. All that aluminum will grow some as well depending on the temp you run it. Man this would be right up my alley. I’ve ran so much AN line and installed so many AN fittings. I have all the tubing benders and 37* flaring tools. Spent a fortune on my benders and flaring tools as they didn’t have all this Chinese garbage available when I tooled up. Seeing this gets my creative juices flowing and ideas are coming one after another lol. I’m a perfectionist so this would be a dream to build
Interesting, they looked too loose to me. Won't the belts get a bit looser as they heat up and break in?
Remember to use submersible fuel line and a fuel tank sealer for the inside of the fuel tank. Over engineer the vital piece and bits ❤
I wonder when the first test drive Video will come 😩
Fragola lines for the win. I use them on my setup. I can route them exactly how I want, and there is zero collapsing of the hose.
What's the capacity of that fuel tank?
i dont get it. you dress like a highlevel business man but talk like a engineer from a high level company. is there a video about your background im interested. cool shit dude.
His insta says he's a certified general commercial appraiser and musician. Labels and titles are never important, though, and what he's putting together is very special and from here, the execution and thoroughness are what's not common in builds I've seen, especially with this much truly custom work. He seems to take into account failure and maintenance and seems like his plans don't need much iteration, again, seeing this from the 'couch'.
I would change that white poly material in that coupler with a brass/bronze Bushing. A softer metal than the rest of the coupler.
Question about the dry sump. Why didn't y'all go with a Mazda style dry sump front cover?
The Mazda dry sump is insufficient for volume and longevity will be limited due to design of pump gears in aluminum housing. Furthermore, rebuilding the pump for maintenance would require removing the front cover and waiting over 1+ year to replacement parts from aftermarket suppliers since original Mazda is discontinued
@@dzmazzei I know there are aftermarket billet options, but I would assume the volume/flow wouldn't be much different.
Thanks for the reply and good luck can't wait to see this thing ripping!
Thank you! I believe there may some really nice aftermarket options hitting market soon that do offer easier maintenance too!
Make sure to check those anti collapse springs, I'm not sure what coolant you are using, or if you are just using straight water, but there are usually corrosion issues with those springs, within a year sometimes. You may be totally fine, but just fyi
those dry sump pumps seem to produce alot of pressure i can think of a few RUclipsrs that have had problems with it not sure if they did something wrong but i hooe yours is ok its a badass build
Quick question,how do you calculate the ratios of your pulleys,by number of teeth like in a regular gear driven assembly or by pulley diameter?
You can do it by either! It's the same thing in terms of ratio
@@dzmazzei thanks for taking the time to anwser
11:50 rotational inertia goes up with the radius cubed, why not titanium for the rest of the hardware that are rotating further from their points of rotation?
Beautiful. Can you give me a ride. I'm from Louisiana. I love rotors.
Really impressive project. Looking forward to next pisodes.
But I would be little concerned with that alternator running close to 30k rpm with what looks like 3:1 ratio pulleys. Some friends had problems with burning alts by overspeeding them. But if this alternator is designed for that kind of rpms that its ok :)
Thank you yes it's a concern but according to the manufacturer of the alternator it can handle 20k rpm, and the ratio setup will be around 19k. So on paper it should be okay. Just have to test and see like all things!
Sweet Trials Bike in your buddies garage
The best of the best. Wonder the total cost when done!! Lol.
He'ssssssss backkkk!!! YES
DOES IT 🔥 🔥 🔥 🔥 🔥 YET?.?
Some old le mans cars stuck the alternator on the output of the gearbox to be able to move it to the back, sure you won't charge during standstill but if your battery is big enough then it won't matter
Mad mike has his 5 rota going in New Zealand.
I love how overbuilt this car is
What are you doing making videos ? You have a car to finish !
Your last one was bad ass this one is looking to be insanely bad ass.
I wanna see @mgcharoudin drive this on the Nurburgring!!!
How much Blow did he do before this interview😂😂
I would add some type of aluminum plate between the block and those lines
When are you going to start it up?
great job, as always, David. but im surprised you are powercoating these parts. but it does look like the paint is looking good so i guess its not necessary
all those lines being very close to the frame or that nut...will be a problem. You can calculate all you want, but you will have more vibration than you think when you are actually running/driving, and things are flexing even just from harmonics, or cornering loads...etc Stuff is going to contact and rub and erode FOR SURE.
Especially not in very accessible locations...that's going to be a problem area down the line. Which I guess might not be an issue fast enough, and you'll have the F1 style lines before the braided lines wear through. But seriously that stuff can happen VERY quickly.
Look into the motion detection software that can take even low resolution remote camera feed data, and calculate partial pixel shifts in shade to play out the full range of motion those parts are seeing during operation. It can be pretty cheap to do, and at the very least is very cool to watch with little time/money invested
19:37 That ~2” long oil hose is concerning. Have you considered clocking each of the fittings like 30deg so that you can have an s shaped hose in that location? Don’t want you to loose oil!
Are you referring to the 90 degree bend on the right side ? Or the 180 degree bend in the middle ?
If you're referring to the latter it has been replaced with a straight line, as can be seen in the later scenes
Sorry, my time stamp was off to give very clear indication. I was referring to the very short hose that is in frame at 19:45. It is adjacent to the second from the front rotor and has about 1/8” of hose between the two coupling ends.
Wish you had merchandise bro. But i understand the lack of subscribers 😢
*When are we going to see it hit the track with some other cars?*
Thats amazing…but we’re all dying to know: how pissed were you when MadMike announced the worlds first 5 rotor?😉
I was actually pretty happy to know that the eccentric shaft will work!
Super weird you decided to do welded aluminum hard lines. If you're chasing weight bmrs offers huge saving over archaic aluminum hard lines both in actual and wet weight.
Soft lines have limited min centerline radius
did i hear you correctly when you said 20,000 RPMs? 😬
I've heard "gone over and torqued every nut and bolt," numerous times from automotive content creators. This is probably the first time I've believed it 😅
any chance you could replace the air struts on my cayenne. ....lol
Just like the timing belt in a Honda v6
Don't know why but I can trust this guy with my sister 😁
Not sure if u gonna modify the manifold like u did on 26B rx7 that sounded 787B
What do you mean? The manifold is gonna be custom made. There is no 5 rotor manifold
