Should've saved that $6,000 for the next engine 😂
are all subarus rally cars that bad?
@@alf3071Yes and No, the engine design is flawed and they are very easy to destroy but as far as we’ve seen they haven’t done some of the tried and true methods of preventing the oil starvation issues Subies have when taking hard corners. One of the biggest is using an aftermarket oil pan with a baffled design.
@@alf3071 stock the engines will last long, modding them you need to be careful and spend money on mods to support the extra power
Porsche Boxsters are available at around 6grands, just sayin.
PORSCHES FOR THE NEXT HI VS LOW !!!
@@alf3071 They're god forsaken junk piles and it boggles my mind how they have such a big following.
If Nissa Altimas had a huge following, everyone would be scratching their heads.
After seeing how expensive this season is, it makes a lot more sense why some of the other series went away and why it took so long to produce this. Love to see it!
Bring back science garage
@@hotgarbagellc
I miss Bumper to Bumper myself
i mean tbh up to speed was a low budget series and i think that they wanna step it up more and that's why it went away
it was good early on to grow the channel and the brand but they're evolving into something better
@@aaronburratwood.6957 Yeah, B2B was good, and well suited to letting Jeremiah's nerd flag fly while making complex engineering concepts a lot more approachable. Also, this is the best description of the Otto Cycle ever: Suck. Squeeze. Bang. Blow.
Well and the simple fact that society is as braindead as it could possibly be these days, and majority don't understand how the platform even works. Most people think everything is LIVE or present day was filmed within just a day or two. Not grasping that most channels film their "episodes" weeks to months before hand.
Cause we know this whole hi-Low was starting being filmed in May/June and probably ended by August. But yet people think this is all done just last week in the beginning of December
I really liked Nolan's attention to detail on where the vortex generators actually needed to go for his application. I've always thought it was strange that they seem to always get put above the rear window whenever a spoiler was used. Nolan looking back at his "test" footage and going ahead and putting the gens on the glass where it looked like they needed to go according to the yarn movement is a real big function over style and big brain move in my book. That low car front splitter made from a template copy and plywood was the jam as well.
I'm critical of vortex generators. I wanted it to work for them, I think the tiny model was too small to represent the full scale effect since the air particles weren't shrunk down as well.
Random question, are spoilers any use to FWD cars? I don't enjoy hating on some people's builds, I'm trying to be better lol
@@Camburger I’m not quite sure. Like yea they work for all cars but I feel like you’d wanna focus more on maybe a front splitter over a rear splitter. But if you can do both that’d be great too
Yeah, I don't think those really do as good of a job as they could be doing if they are halfway down the rear window. Vortex generators make vortexes from laminar flow (that's where the yarn is still flowing straight), the air that's already turbulent (that's where the yarn is going crazy) is next to useless. They need to be placed where the flow is still laminar, to extend the point where it separates and becomes turbulent further back. Placing them where the separation (the point where laminar flow becomes turbulent flow) has already occured doesn't do much.
@@CamburgerKeep in mind spoilers don’t make a noticeable impact until after about 70ish MPH. Running just a rear spoiler on a FWD vehicle will actually work against it because it’s taking downforce off the front tires which will be less grip. You would want the front lip in tandem with the spoiler so the whole car gets pulled down.
@@Camburger The wind tunnel was only configured to measure lift, not drag, but drag is the only thing the vortex generators should really be affecting. They'd have to have used a horizontal force gauge to have shown if they actually meaningfully impacted the drag. Vortex generators are also much more apparent at higher speeds. Their tunnel was good as a proof of concept, but I highly doubt it was producing 120mph winds like the vehicle would experience.
Jeremiah continues to be the most underrated donut team member, as an engineer I love this man, making learning fun is such a great talent to have and he’s got it
The wind tunnel element of this video is absolutely awesome. Really cool to see genuine engineering principles being brought into this.
I've been enjoying the dual story lines. One team builds and another does some explaining/testing.
I know right we get to see the aero of a banana
that's why big papa jerry is by far my favorite, that lil engineer brain of his and the knowledge he had taught me👌🏽 he is him.
I agree. The wind tunnel story line accompanying the installation of everything was rad. Great work Donut!
This is what makes Donut better than some other car channels. They have an actual engineer working for them (Jeremiah). So we can see this type of content! It's awesome!
New show idea: give each of the hosts their own budget to buy and modify any car they want with the goal of being fastest on track. It could be all the same amount, or you could do random drawings to see who gets different amounts. Everyone can take what they have learned from hi low and actually try and apply it. Also you can have some mandatory parts (safety equipment and paint jobs) that some of the budget has to go to.
I really like this idea!
Oh I'd watch TF out of this. It's like the way more expensive and car version of LTT's craigslist budget build challenges they used to do.
That would just be a private racing club, would get insanely expensive for the channel lol
Mad idea for a series
@@jaimespencer837 a car scrapyard wars would be kind of sick
Building your own wind tunnel and being able to explain all of this is just great! We love ya donut
Whoever came up with the idea of talking about your sponsor while putting random objects in a wind tunnel is a freaking genius. You should adopt that strategy for every add. This is the first time I've ever watched an entire ad on donut and only one of a couple times I've watched a full add on any CZcams channel. I did watch decent chunks of the Uncle Jerry has and enough of the first car relationship therapy sessions to understand the joke, but inevitably fast forward to the show content. I'm an underground member so that's how I eased my conscience about not watching the ads. But I'll keep watching them if you keep doing cool stuff during them. I'll have to.
Can confirm, it was genius
Yeah I’m absolutely loving that. It’s the most unobtrusive way of doing a CZcams ad that I’ve seen. It’s things like that that make Donut great!
I love how they utilize the talent at doughnut, James, the personality and spokesperson, Zach, all star mechanic, Jerry, the engineer who explains things, and Nolan represents us, the frustrated enthusiasts who is Ballin on a budget but you can see the frustration in his eyes but eventually turns to pure joy once he's finished.
Don't forget the editors which make an amazing job!
I didn’t like Nolan at first, but i was in the wrong, he’s a cool dude, has extensive car knowledge, and he’s also one of the best drivers they have. Kudos Nolan, and my apologies for judging poorly, you’re the man!
And don't forget Garage Daddy Adam who brings the mechanical knowledge as well as being an actual professional racer to help truly test the builds on track.
And Jimmy
You nailed the roles perfectly. Especially Nolan. That might be why he is my favorite.
Man! That wind tunnel to show the improvement was an amazing idea. Kudos to whoever came up with it
1931: The world's first full-scale wind tunnel opens at Langley Field near Hampton, Virginia.
1936 Chrysler Imperial Airflow. The Airflow was the first American car designed using a wind tunnel.
I did
Came to say the same thing. You guys are legit, scanned and 3d printed then wind tunnel tested. Amazing dedication, brilliant execution. You'll inspired another generation of shed engineers and those now kids will push the game way forward.
@@scissrface2182 Mate those are a couple of really good car fun facts...cheers.
Aeronautics graduate here, great video and the concepts were extremely well explained! One thing to note though for low team is that the vortex generators help keep flow attached by energising the flow while it is still attached so it can remain attached for longer. Putting the generators so far down won't really be helping as by that point the flow is already separating.
Yea, they should have asked Jeremiah on that. Mechanical engineers have low level aero engineering in their curriculum, I think he would have caught that.
Maybe that breaks the rules?
Gotta say this has been your best engineering explanation yet. It was simple and accurate and the wind tunnel was great! Jeremiah killed it
I realize that your wind tunnel was an oversimplification, but it really is AMAZING for a car channel to have built what you did to show and explain the concepts.
Agreed! Really like what Jer-Bear has brought to the table.
Even had a lexan gd 😂
One thing I think would be really neat to see here is how they take the cars to their ultimate locations in the finale to see how well they do. The track is more accessible for sure, but would have loved to see a mountain drive at the start, stock, then return to it and time both results and see how much improvement there is. That is what these cars love doing
Hey, they built a rocket car. Rocket car.
Pretty awesome, but air doesn't scale, it acts as a heavier fluid at small scale than when at full scale. That's why bumble bees literally swim through the air, not fly. But still awesome.
That conclusion seemed really rushed. I liked how in the first season you sat down and asked each other "does more money mean more better".
The results as presented were pretty definitive though. The cheaper option was also the faster one and there didn't seem to be too much difference in installation. There didn't seem to be a lot of nuance to debate.
@@ndubitably Valid points, but it'd be fun as viewer to have more reaction than 2 sec conclusion
@@ndubitably This isn't correct though. I made a post about it. Its like putting a new wing on an f1 car and "only" gaining .1 second. Then claiming that low car must be better because it got 1.2 seconds. Makes no sense. High car is likely closer to the potential of the car overall so addons will have smaller gains as you get closer to the limit. Where high car was still 2.2 seconds faster on the same tires.
@@emmanuelhpun I generally enjoy those discussions, but this doesn't seem to be the test for it.
@@TheBajamin exactly my thoughts
Since aero isn't entirely based on how it's made ( expensive materials etc ) but more on how it fits the specific track needs for the specific vehicle you want , half of the 6000$ should go to a consultation from a aerodynamicist for a custom made package. That would definitely show a better improvement on lap times.
I think the intention was for aero packages you can buy off the shelf rather than custom so the viewers/us can be informed whether we should spend the upcharge or spend conservatively.
@@shinn43 Fair enough. Even though, I doubt if anyone wanted to mess with that high of a price aero parts without running some type of simulation or testing. Otherwise it's not testing performance gain , but only the looks of it. Given the fact that they are building time attack cars , the splitter and the wing should have some type of tune.
Aero is a very tricky thing were you could spend so much yet have almost no time gain at all if you don't plan/test.
In fsae for example, some teams opt for not adding the weight of aero components just because the aero benefits don't "outweigh" the aero "gains".
You are KILLING IT with the sponsor segments. I have literally never seen anyone do a better job of it.
Now we need another yarn "test" to see if Nolan's "vortex generators" work where they are!
I thought it was a great idea
Don't think it will. You want to generate vortexes whilst the flow is still attached, so where people normally put them. The flow is already separated where they are planning on putting them, hence they aren't as effective.
@@khris8736 I understand why they're typically placed where they are. Nolan placed his where he did based on his own evidence. I now want to see the same test done to see if his placement did anything, whether positive or negative. Do the same with Hi Car too.
@@amorton94 yeah deffo seeing it would be nice to see. My comments were more about what I would see on the follow up test. Based on experience, I would expect the change to be negligible due to the above comments. Seeing the follow up test on hi car would be really good to see and help visualise improvements.
Definitely @
Well now I'm less embarrassed of my DIY parts 😂
if it works and it works dont be embarrassed b proud
Don't ever be embarrassed about that. you're built, not bought. That's something to be proud of.
Don’t be embarrassed. DIY is part of the car game. Sometimes you have to make your own parts
@@Mikey.5000 he said less but yeah
these series have gave me the confidence to just get the shit done 😂
I loved this episode you guys did a great job explaining aerodynamics in the simplest terms possible
Thank you for explaining what each aero part does on the car. Really helped with understanding why each part matters!
I wish you guys would go back to the format that had Nolan and James discuss which mods they felt were most "worth it" at the end of each episode.
They couldn't here because they had no idea.
@@Marcara081 Well they haven't in any of the episodes, James is just saying "okay high car won this time" mostly off raw performance and I feel like value for money isn't even being considered in some of the episodes
That's for us to interpret and decide
@@biocta this series is def rushed and more haphazard then previous ones, i think it's because of all the stress and problems they have been having.
@@bigman7083 Oh yes it’s very rushed, it’s a shame, but it’s absolutely understandable considering they’ve been going through a new motor every episode. I hope whatever next season is they pick a car that’s actually reliable and we get a return to form of the last two seasons
Donut dudes,
I'm literally one class away from my Aeronautics degree and you guys (Jerry, but I'm sure everyone was involved in research) did an amazing job discussing the aerodynamics of cars, producing lift, and producing downforce. Keep up the good work!
yeah, as you can tell, the aero used on this type of car are really 'anti-lift' devices. It takes massive parts to actually generate any kind of downforce at those speeds.
@@Jonasz314 which is wild. If you’ve ever seen a plane with a “T-tail” it kind of looks like a wing on a car. That T-tail is actually generating downforce, or negative lift. It has to do to keep the dynamic stability of the plane.
In my mini moons of research I vaguely recollect a cancellation effect when combining a roof diffuser with spoiler. ?
That’s a cool degree man, congrats!
@@rage660 I’m not sure. I specialize in planes not cars lol!
"We bought 7 nearly identical Subaru boxer engines" 😂
Thanks for your sacrifices guys lol
The effort this video took to film is felt and appreciated my dudes!!
I love the new series, but I miss the parts at the end when everyone sits down and actually discusses each of the car's mods. Like the overall hassle of installing, and discussing whether it was worth the time and money, and if its even worth doing something similar yourself. I understand a lot of the info is in the video, but the overall conclusion for the part is a nice way to wrap things up.
ps: team locar
Yea the endings feel a bit abrupt, but then they haven't exactly had a easy time and are probably crunching to make up for lost time.
@@PaletoB 100% yes. I think it's worth mentioning in case they think people don't miss it, but I would rather a video that actually releases than a video that takes months to polish
@@christinabunbun9272 There are deadlines to videos like these. I'm sure ebay motors sponsored this on the expectation the videos would come out around the holidays. They probably didn't have the ability to wait to release them.
Yup, I agree 100%. My favorite was the lsd episode of the z's
I absolutely love this series. Never stop. Definitely bring back Nolan and James discussing which mods were worth the money at the end.
Same I miss being told if more expensive means more better
For sure!
Jeremiah’s engineering integration into all episodes of this season have been fantastic!
Adding those under trays really took this challenge up a notch
This show has made me afraid of ever buying a subaru haha
Don't let it. These guys don't know enough about subarus to properly mod them for track purposes. Check out the latest Flatirons Turning podcast about why these guys keep blowing up these boxers and how these guys are doing things improperly and blaming the cars.
@@grammerpolicedeputy6913 that's like the guys arguing that the 6.0 powerstroke being a great engine. If you have go put $20,000 I do the engine to make it a good engine, it's a garbage engine.
@@grammerpolicedeputy6913 couldn’t agree more. Subaru’s are such fun and reliable cars if proper tuning and maintenance is done..beat the shit out of mine for 5 years and never blew a block
Good, it should. They're shit boxes and always have been. They just checked a few boxes which is why they're popular. Good aesthetics, AWD, turbo, manual, rally history, with the added bonus of sounding good (even though now they all sound like shit with equal length headers because it took someone 20+ years to figure out that unequal length was causing issues due to differences in exhaust back pressure). Add on top of that, you simply can't find one anymore that isn't clapped out. If you somehow do, you're paying stupid money.
But as long as the subi fans keep buying shit cars, my cousin will have a good job fixing them, so keep on buying them! 😂
@@lovingtennessee7726 I guess every engine is shit then since race motors cost a minimum $20k on any platform 🤷♂️
As a former WRX owner, I was waiting for another catastrophe on track and the suspense did not disappoint! Good work, gents! The transparency of showing the down side is appreciated!
If these guys knew anything about subies, they could've avoided all the trouble from the gate, but they don't, they didn't, and they got what they deserved.
I almost got a WRX not too long ago. I’m glad I didn’t. They’re cool af but I just don’t want the smoke (pun intended).
@@juvedoo99 Subis aren't as bad as they have been represented on here. I like donut but if you got to someone who knows what they are doing with subis they can handle a good amount of power on 1 stock block.
I love how much of a rush production is once the track day rolls up, really seems like a time crunch
I love this video! Thank you guys. Thank you Jerry for the explanations about aerodynamics. I'll use this video to better explain to my colleagues how aero works on a car and it's not just a "stupid accessory".
Next Season can you switch the teams between high and low cars? I think it'd be entertaining to see how each of the teams reacts to now having to deal with the others parts considering how everything has gone so far.
keep up the awesome work tho!
Considering James is the Editor in Chief, head writer, and everyone's boss, i'm gonna guess he's going to continue writing scripts where he happens to be in hicar
@@leviof1996 ☠️
I love that clip of James crashing every video, it's gold. He will never live that down hahaha
From what video is that?
@@xrepressiivproductionz8481 brakes
Did a good job demonstrating friction and pressure drag with the model on this video. Having an engineering degree with an automotive concentration, this video was very enjoyable
Windtunnel part added so much to this episode, amazing work!
For me, this episode was one of the best from this season. It just had the right feeling, the right mix of knowledge, science and humor. The installations were shown in detail, easy to follow and understand, immensely explained but thrilling to watch at the same time. Great Episode
I love seeing Adam getting involved in low car. He's a get it done kind of guy.
Y'all did an amazing job on the wind tunnel segments. Threaded the needle of keeping it simple enough for the average viewer to understand, but in-depth enough to teach something.
I love the continued increase in the SCIENCE behind the equipment. I watch these with my boys to get them interested in STEM
Jerry carried this episode with the nuance of aero. More like this pls
Donut is the only channel that can make ads funny and watchable
Nah. Internet historian is much better at it although the content is completely different.
Tomska?
Vilebrequin !
Internet historian was already mentioned but I'm gonna add Ryan George to the list as well, those Ads are basically a second skit after the main one.
@@aBoogivogi Raycon good; wires bad.
This shows are so special. I'm writting an essay about cars and I decided to add ero dynamics and this video is helping me a ton.
Appreciate the time you guys took to explain what each part does!
I would like to mention there is a reason why Subaru went with the roof spoiler versus the vortex generator on the 06-07 STi. It’s with the slope angle of the rear window pairing with the factory STi spoiler. The roof spoiler was able to redirect air more effectively down the rear glass, producing more air under the rear wing. The factory STi spoiler would shake like crazy at speed on the MY04-MY05 STi, but the spoiler shake was drastically reduced with the implementation of the roof spoiler. There may have been better results if the roof spoiler was utilized over the roof diffuser.
Some may bring up the Evo having a roof diffuser. The reason it worked better for the Evo was the rear glass angle was less than the STi, the trunk lid was also longer, and the Evo VII, VIII, and IX had a more raked spoiler, where the STi was damn near vertical, so for the Evo, the roof diffuser worked efficiently, where the STi had more benefit from a redirection of air.
This episode truly slaps! Jerry getting to nerd out and use his actual engineering with the mini wind tunnel, Nolan getting the satisfaction of mo money not being mo better, and no one blew an engine! Just lost a tire, which is stupidly minor in the grand scheme. Awesome episode, boys! 🍻
The better you get, the harder it is to improve.
Loved the cinderblock in the wind tunnel btw lmao
First time I see this channel. Watched it, didn't expect it to be so thorough and high quality, the modelling part was super interesting. Loved it.
It would be interesting ina high/low season to do a followup with a third car, where you take the expensive parts where you'd recommend them, and the cheap ones you'd recommend, and see how that car compares against high and low.
Hi, low and best of both worlds
So they need a Mid-car? I agree
I'm not even halfway in and this might be the best episode of Hi Low yet. I'm hoping Low team may be onto an advantage with the vortex placement and the $100 active aero on the trunk.
Love how technical these videos are
I am so enjoying this series! Keep up the great work!
A bonus JerBear tutorial and a mini wind tunnel? This is a right slice of goodness! 👌
Good episode, especially with the wind tunnel. I do miss the ending where you guys break down whether or not spending more is worth it, though.
they said in this video that low car won, spending was not worth it (low car actually performed better for cheaper--probably because fabricating besope aero from video analytics is better than buying expensive off the shelf stuff)
Lovin this series. Gettin a little low car in the high car recipe and vice versa!
With the numbers you’re already squeezing from high car .6 seconds is a meaningful gain, low car gaining double that is easier considering. What I’m impressed with is that both actually improved on time with the weight increase, goes to show aero is pretty important
The wing doesn't produce downforce from air pushing against it, but think of it like an upside down airplane wing. The air moves faster under the wing then on top, causing negative lift. This is controlled by the shape and angle of the wing, similar to a wing airfoil.
Spoilers are the ones that do that, right?
Some of the downforce is also from the angle of attack, as in airplanes as well
@@V8_Diva Correct but they also disrupt the air coming from the top of the car killing the lift that the body may be generating.
@@V8_Diva spoilers are designed for improving airflow, instead of increasing downforce. They’re useful for SUVs and hatchbacks since they have large, flat rear ends (2:30 negative space) which create larger negative spaces which reduces stability at high speeds. For simplisticities sake: spoilers improve a car with bad aerodynamics, a wing improves a cars downforce.
@@niccilus7758 I'm also referring to the massive spoilers found on stock cars.
These sponsor sections are so good, makes me wanna watch em again instead of skipping
Damn, I wish I was chosen. : (
Hail corporate
Much respect for building the wind tunnel and doing scale model stuff, that was super cool
Fun Fact: Both carbon fiber-reinforced plastic _and_ plywood are composite materials. A composite material is a combination of two or more materials designed so the strengths of one will overcome the weaknesses of another.
With plywood, those differing materials are woodgrain set in alternating directions. In CFRP, the carbon fiber holds the epoxy resin together against tension and shearing forces.
Nolan’s jacket is sick, fits his Japanese mechanic look perfectly! Love the content can’t wait for the next episode
“We are going to test these components HEAD TO HEAD and see who’s motor blows first this episode”
"We blew an engine so today we're talking about diagnosis and finding out how screwed we are."
"...wait, is this a repeat?"
Best video of this series. Really liked the testing with the home made wind tunnel.
This series has been the only entertainment I’ve been watching lol , loved the Tacoma series
Science garage was really one of the OG best series from Donut. But seeing these high low series it's pretty clear that it would have cost a lot to make other series simultaneously. Love this episode 😍
I feel like science garage was very cheap to make though. Just do some research, put together a slideshow, show off a couple parts, then you're good. This show seems so much more expensive.
the model diffuser demo was impressive. great job as always!
Agreed
I love the aerodynamics lesson. I’m a pilot and this is better than a few ground lessons I’ve heard 😂
i am an engineer with a large back ground in fluid dynamics and this is really a pretty good explanation of concepts coming from donut
like
MOST of the time i was like "ok thats pretty good"
stuff like "vortex generators" are just not dramatic to be impactful tbh
Are we eventually going to see a HiLow drag racing season? 👀 I’m honestly looking to put my life into Motorsports and automotive full time and the donut media crew has inspired me!
Jeremiah is the reason I'm here. We need more of this guys engineering knowledge
Your expalantion with DIY windtunnel is great, it explains a lot.
7:02 I study mechanical engineering at the university of Ingolstadt (hometown of Audi) and they taught us that turbulent air is better attached to an object which means that the vortex generators are way to much behind the “big curve” where the air starts to detach from the car. They must get attached shortly before the air starts to detach to generate turbulent air flow so the air sticks to the car for longer. Audi for example generated turbulent air on their DTM cars by glueing some kind of wires to the diffusor which allowed them to make the Diffusor steeper without detaching the air flow. Hence they had very slow air behind the car but very fast air unter the car.
Ok…. I have to buy a T-Shirt now, just to help fund Donut’s consumption of boxer engines in this series 😂
Might wanna buy a few lmao
10:16
FYI, don’t mount mount your splitter supports to the plastic bumper. For something that will see 10s and maybe hundreds (optimistic) pounds of downforce, the last thing you want is the support ripping out of the bumper or the bumper ripping out of it’s attachment points. Secure it so a stiff part of the body and preferably the frame.
The quality of these videos are unmatched man
God I lovw this show! The video quality is badass! Keep it up guys. Late nights in the garage for life
Congratulations! This episode was awesome!!! The explanations was very cool and interesting! 🙏
Love how well the new high car color goes with low car.
i love these episodes so much
Wow Jerrbear that windtunnel is sick! Thanks for the intellectually stimulating episode! Also, IMO it makes sense that even cheap parts that are strategically placed would yield better results than "nicer" parts that are mass produced to fit on a variety of cars.
Getting into some pretty good times! Curious to see what you'll even do next in the chase for better times.
I love this new format of the video. It's like all your series combined. Jerry's explanations alongside you guys actually doing it, it's really nice.
Gotta say, the scale model of the high/low trucks in the wind tunnel was a cool callback to the previous series at 4:50
Gotta love how James is never pretentious.
Hi Low is amazing as a series, it takes time and money and honestly seeing you guys taking hits like blown engines really hurts. You guys are busy but I kinda miss the style of older Hi Low. More relaxed, showing bloopers and racing on the track. The building takes a chunk of a vid I know but seeing the racing take only a few minutes makes me wish there was more. Miss the old Hi Low but great job either way!
I'm curious to know what each car weighs before, and after all of these mods.
High quality production videos as always Donut. You guys are unmatched ❤️
I'm 15 and have learned most of the stuff I know about cars from donut big thanx to you guys
I'd be really interested to see Hi car and Low car in a wind tunnel now, I want to see if those lower mounted vortex generators made any significant contribution 😅
I also wonder if the big difference could have been caused by removing the entire bumper vs just the splitter, if that had a significant impact.
Either way, awesome episode as always, Donut Media really is the best.
i doubt it. the strings there weren't flowing in the same direction not because of disrupted airflow, but rather a lack of airflow. and u want as much air to flow through the vortex generators as possible so u have as much clean air going to the wings.
vortex generators already make a very small difference in aerodynamics, and if mounted where low car mounted them, i have no doubt they did absolutely nothing
I like how they knew that putting a camera in the wind tunnel immediately meant we wanna see the camera's perspective of in the wind tunnel
You need to make a series where you test out basic work truck highs and lows like winches and storage racks etc
I don’t think you guys can say you bought 2WRX’s anymore you’re basically bought four at this point
Babe wake up new Donut video
vortex generators on the roof are for side ways airflow to help direct it to the spoiler, it doesn't do much normally but at the highest level of performance at full speed, it helps.
Adding downforce like the splitter and wing also increase drag
Front splitter from plywood? Jeremy Clarkson approves.
I love, love, LOVE that they have Jeremiah breaking out his "Bumper-2-Bumper" host energy and have him explain the mechanics and engineering principles behind these modifications. Adds a new dimension to Hi-Low that wasn't there in the previous seasons.
I love how they use a blob eye for the animations. Definitely the best impreza overall.
Love the cars are pain t-shirt ad, as soon as he got the wrong part 🤣 🤣 Very accurate 👍🏼
