This build is one of the best on YT right now. The access to the struggle and victories is great. Wish I’d known you were in town. We would’ve come down to MSR to see the car!
I only came to your chanel to learn about suspension geometry for a project I will never be able to do... I am totally blown away and have watched the entire series.... seriously good job. Great enthusiasm knowledge and just the right amount of detail, I'm thrilled its working so well now you have it on the track .
Either you're really unlucky or the guys at Carvahal Motors are geniuses and knew just the guy to invite over to have their CNC issues taken care of 😂 In all seriousness, I'm glad it worked out for both of you, they helped you make the first version of your wing and you got their machine back up and running, everybody's happy.
Are you some sort of wizard? You have incredible knowledge not just about cars, but electrical and and mechanical engineering. Well done. Your channel should be much bigger than it is. Thank you so much for producing such high quality content.
I seriously hope you didn't have to pay for that wing. Its a rushed job that didn't come out right to begin with AND you fixed his busted ass C&C! You literally saved him 1000's of dollars in repair costs and downtime! Not to mention expensive components that some other tech woulda sold him instead of fixing his. That was seriously amazing that you were able to do that for him. I hope he realized that and treated you accordingly. Ok. Concerned rant done. 😁 Cheers!🍻
Yea, had the same thought but I can’t imagine that Carvahal Motors didn’t appreciate (literally) his efforts. It was a rushed job partly because of time constraints of SK8212 himself. It seemed to me like they had a very good cooperation, so let’s not be too judgmental.

However I fear that (which is far too often the case) he wasn't properly compensated for that shit show, which he handled quite gracefully.
@@The_Angry_BeEconomist No, that is not how the wing was made. The CNC machine cut foam pieces, which were then covered in fibre-glass. These pieces were then glued together. There is no mould to cast further cores from. To make another wing, he would have to machine another set of foam cores.
Paul Standeven Hi, It’s difficult to see but I got the impression the foam pieces could be used a second time. I think that’s what The Angry Economist meant.
Bigger endplates help keep the rear stable during a turn but you need stiffer mounting for the sideload on the wing. I prefer swan neck mounts, since most of the downforce comes from the bottom of the wing and swan necks keep the air way cleaner. Check out the article www.mulsannescorner.com/rearwingLMPCFD2009.html or Race Car Engineering's January 2012 issue.
Came to say the same thing. Attach to the top of the wing, NOT the underside. Keep the underside clear for air travel and allow the wing to do it's job.
Man, building this car was worth it just for the opportunities its made available to you. These are some seriously amazing experiences that money just can't buy. Its like a golden ticket to a life that most of us only dream about and you've made it all happen with your own two hands, some brilliant know how and the nerve to commit to it. You might be several years my junior but you sir are an inspiration to me. Well done man. Ok that should be my last comment... Lol Cheers!🍻
oh man do i love this channel, great content always. it is very rare to find a RUclipsr who actually understand cars, im not talking about the ones who just read something on the internet and just relay it here without proper understanding.
i bet all those racing teams in TX are still talking about that time that got to meet that cool cat from youtube SK8215, who built his own amazing time attack car.
Love your description on how the different sections of the wing work.... Keep talking buddy !...... And we have the same noise issues in Australia... race tracks been there for 60 years then houses move in close, complain, then noise limits come in... I race bikes and it's a pain in the arse !!!
Cnc repair was great. Wing design was made for clean uninterupted air. This only works if wing is on the front. At the back youll have so much tubulent air they cant desing your wing unless you go to wind tunnel. Good luck with the buil! Geat work!
Such an impressive build. Great video. Love the information. Absolutely love the fact that you show us the struggles and attempts that it takes to complete something. Genuinely appreciate the content. Feeling VERY inspired.
Yeahhhh good to see some rear downforce. Going to need to redo the rear tyre angles etc though. As an aside, I really appreciate the simplicity of lots of the car - making decisions about what is necessary / not necessary and not making it more complex than it needs to be.
Fantastic job getting the CNC machine repaired! Re wing looks great and love the engineering math and consideration that went into the design and fabrication of it. Nice to get wind tunnel testing in your time attack car at some point. That is asking for a lot I know. Keep up the great work and enjoy your time in the USA with your ASL55.
Pretty sweet to get this made professionally while on your trip. I was wondering how you were going to make the wing DIY in your garage. Did you get a discount for fixing their CNC machine?
lol, DISCOUNT?!?!...for that pos wing??? those dudes should have paid him thousands to fix that CNC machine (guessing market rate, and also how many service calls it would take to equal _one_ SK8215 fix, which is probably closer to infinity than 1).
Very informative, I'm planning on using a simular design double element wing and thinking of incorporating a load cell into the bottom to measure actual imposed downforce
I'm in CA, in the Bay Area, if you're ever in the area and need a place to crash in your travels hit me up. Id love to see this thing in person! I'm also a race instructor at several tracks in CA, so maybe I'll see you out there!
2 things i am surpriised about in your wing, 1: its not a top mount gooseneck and 2: its quite high and not as far back as i would have put it. The lower and further back from the car the more it interacts with the diffusser. Air coming off the diffusser helps the air velocity of the underside of the wing and helps the air stay attached making it more efficient thus more downforce with little to no drag penalty. Just my 2 cents....keep up the good work bro
NICE!! Customer fixes the machine, I bet they were glad you showed up. So you were impressed with the quality of the other race cars, me too. I wonder how much lighter those cars are compared to your car, I bet not that much lighter. Something worth looking into!
A few hundred kilos I would guess. Carbon fibre suspension elements, aluminium frame, everything carefully calculated and optimized no doubt. Watch this 19:50
20:24 Mmmmm the Alcon one peice calipers with fully floated discs are such a great piece of kit. Money can't buy better brakes than AP or Alcon calipers for full on race cars.
You could also improve two things: a bigger endplate, and add some "rectangular holes" (like 25 mm x 100 mm) near the border of the endplates to induce a reverse flow to "cancel" the vortice stream created from the air escaping from the end of the wing/endplate interface!
What a mess in that CNC's electrical box. Whoever set it up initially did a poor wiring job. You sure did them a great favor fixing the cb problem. I don't think they could have had it fixed this efficiently if they hired a professional. Hope you get a proper wing up there soon 👍
Really cool! I actually worked on the design of the next gen Formula Mazda car at Riley Technologies, the ones you show are the previous versions done by another company. The same place where that red Daytona Prototype was designed and built. If you ever drive through NC let me know!
Good luck with the rear wing, I would definitely take a mould off it before you take it on the track it doesn't look anything like strong enough. The cfd should have given you a lift coefficient from this and your gearing it's easy enough to work out the forces on it. The Safest way is too hang some weights off it and see what shape it ends up..
Hi I've just watched your track day video and there is a way to improve the down force and reduce the noise : make exhaust direct under the car. This way was used by brawn gp on their f1 in 2009
The leading edge of the first element needs dropping so it is about 2° lower than the trailing edge,second element will also need adjustments,easiest way to visualize this is to look at a side on view of a biplane in level flight and invert the image
You are brilliant! Also, did you get a huge discount on the wing? Because you fixed his machinery and helped him build the wing.. anyways I subbed and your vids are great
I fully agree! I think the professionals at the racing teams really know what it takes to get so far as you have come, and thus admire your car. I really your hands on mentality and channel. You show and explain everything what you do. Great, great job and channel. Thank you very much!!
I wonder why not use a hotwire method like the model aircraft guys use? If you work slowly you can get extremely accurate cuts. Take a look at Andrew Newton's RC channel, some great diy methods there.
Putting the wing close to the track underneath the diffuser has a similar effect to a magnet .. the closer to the track the down force increases exponentially .. like a magnetic attraction with the wing mounted high up like most people choose to do .. is counter productive because of the dilution effect of the air to flow towards the wing thus diluting the down force potential.. You need the wing as close to the track as possible .. too close and the airflow will dam and the car will suffer Porpoising .. which is a bit scary .because your eyesight will become blurred . I did all of my ground effects using a disused aerodrome and mounted my wing on scales attached to my open plan trailer which I towed down the runway .
I`m continuously further blown away by you. You fixed their machine on the spot? lmao You must of left that place and they just looked at each other in utter amazement like "Who the fuck is this guy?!?" Are companies begging you to come work for them?
Abhishek Kushwaha -it looks identical to what I just used on a job for rubber (EPDM) roofing underlayment! Cheap stuff, has some fiberglass content and paper/cardboard backing to promote adhesion of the contact cement... Has a tendency to warp and curve a bit, gets installed w large screws and button washers; surprised they would use it for any reason other than low cost? Check out Firestone epdm rubber or any flat roofing videos you will see similar products
8:42 Hey, that's our PRN1 air rivet nut tool. If those are our rivet nuts or similar, depending on the material thickness and rivet nut size those should be plenty strong as demonstrated here ruclips.net/video/lry2YNb1lok/видео.html&t. I'll send you specs.
Why not just make the wing alter its angle depending on how much your steering wheel is turned?. No drag or downforce on the straights and all of it in corners
K.i.s.s. Complicated things tend to tricky and break alot. If you don't need it (because you are planning to race in an open division or a formula series that allsows/requires such things) just leave it off.

awesome photos at the end
I enjoy your videos very much, thxs.
Yes watching in my car at parking lot 🤗
The CFD around the wing is really cool to see. Had you considered swan-neck or side plate mounts?

Amazing
You’re in Texas. If u stop by Houston Let me know. I want to see your car in person. Lol 👍🏼 great job on the car.
Tou can add a gurney Flap on the upper wing element, its reduce a limit layer, reducing a non laminar flow on upper wing
You are the dude!!!!!!
The leading edge of the first element needs dropping so it is about 2° lower than the trailing edge,second element will also need adjustments,easiest way to visualize this is to look at a side on view of a biplane in level flight and invert the image
Fantastic
Would you be able to use your self made wing you had on your e55 and move your DRS over the the ASL?
Did you do cfd on front splitter?
The angles on it look very aggressive and get separation on it?
Nice job. I think the side edges should be round. Why not adjustable?
Seems to me that those wing elements need aluminum or CF tubes spars running down the center to attach the struts and end plates to.
You are brilliant! Also, did you get a huge discount on the wing? Because you fixed his machinery and helped him build the wing.. anyways I subbed and your vids are great
