The first thing you do should be put a huge spoiler on your honda civic
I thought it was stock part. Never seen a teens 90s Civic without spoiler :D
Sander Palu my friends civic EG is bone stock 1.5 DXi
Yeah it adds 50hp
Don't forget red brake calipers, they add 30hp each!
ceejay1992 not really all the ones on Craig's list come with one maybe two (for front and back of course)
Each vtec sticker you have adds 2000 lbs of downforce
lol...noob. vtec stickers add HP, not down-force.
@@djsonicc lol noob. The sticker directs air upwards and creates significant amount of downforce. It being vtec sticker also adds like 100hp per sticker
@@lordwalrus8615 lol noob. The sticker directs air upwards creating downforce, gives 100hp at the panel - or more if you use high speed wax, *and* attracts the honies/homies (Insert preference *here*).
It's true I added them to my camaro and now i'm world champion.
You should do more on high speed aero designs, not many people talk about it, but in my opinion it is hard to get low drag and enough downforce to get stable around corners at very high speeds (200 kph minimum and upwards of 350 kph)
If it were easy F1 wouldn't exist. It's not really an opinion at this point, more like fact.
that why you need active aero, with servos controlling attack angle at all times.
Chris I didn't say it is easy, but F1 are different design to what im talking about, even in what they consider low drag setup it still produces a lot of drag. And that is because they are aiming to achieve fastest laps around track where you have most corners
Ah gotcha. I was a bit tetchy when I wrote that comment lol and tried to be sarcastic without really thinking about it.
Real shit
I bet you would be surprised at how many of us real racing engineers watch and learn from your vids!!! Thanks😂🏁
I just scrolled through the recommended and saw a video from him with "why I left my F1 job" in the title. I think your comment about "real racing engineers" may be misplaced...
¿are you computer engineer from the EA game Real Racing?
@@Xayuap LMAO
@@reaganharder1480 what
@@rodutus the phrasing of the OP kinda sounds like he doesn't think Kyle is a real racing engineer. Like, he's just some college grad who's making youtube videos now. But actually Kyle worked as an engineer for the Mercedes F1 team for several years while they were winning everything, so he's got about as much cred as you can possibly have in the race aero engineering world.
Note1. Big wing to make my civic turn harder
Note2. Vent exhaust straight up through hood to provide down force without drag when I'm pushing my civic to 100+ kmph
Gotcha I'm ready for the drag strip
I wish I could push a car 100kmph, I'd save a ton on fuel
Try bolting a box fan to the rear, and maybe you can make a diy fan car 😂
Gonna try this on my toyota camry
same but toyota matrix hatch!
What did you add on/modify exactly? What were the results? Camry owner here :)
Pointless... Large sedan can not corner on the first place.I should know I drive into corner on highway before... Almost died.... Thank to shit highway road maintenance.
I think some of you don't understand the concept of sarcasm here
i'd love to see more videos like this, but have them slowly step up in complexity and in-depthness. So for example you could begin to get more into individual parts and how the different shapes and designs have different effects. I know that you have done similar videos already, but if these ones were a bit more DIY focused as this video somewhat is, i think that would be pretty neat. Anyways love the videos! Keep it up! Cheers mate.
+1 Such kind of slowly stepping up in the complexity and in-depthness would be really good idea, and we could easily step up our game in aerodynamics. Also it could be a series of videos with "stages" of aerodynamics, like what would be a Stage 1 of aero for most of cars with certain application, another video about Stage 2 where it would be discussed more agressive or different aerodynamics as the power of a car and speeds would increase etc. Just overall, Dakota Snow is right, develope this series more! :D
Enfasess in diy definitely 😁
I don't know what I'm doing here I don't even own a car
Get a job
I have an 03 impala... but car stuff
@@norgepalm7315 maybe he isnt old enough, or doesnt need/want one. money isnt always the reason for someone not having a car, our house costs ~400k, but its in the middle of the city, so we barely need to go anywhere, hence, we dont need a car, we just walk.
@@pancake5830 lol so lemme get this straight, you literally went out of your way to state the goddamn obvious.. to a joke comment. Not only that, but the absolutely groundbreaking, earth shattering knowledge you clearly possess which must be unheard of for a kid your age.. was just a ploy to try and flex your parents home? Lol wtf kid.. I know 400k sounds like a lot to you at your age but, honestly, not trying to be an ass, but a 400k inner city property is actually very much on the low side. Obviously the city etc matters a whole lot here, but you need to chill and stick to roblox bux
0:50 another instance for street use is the Mazda MX5, at motorway speeds of 120-150kph the car is effected a lot by crosswinds from trucks and environment. There are many front splitters on the market which have been known to increase stability considerably.
Having fit one on my own I can vouch for the fact that the wheel feels much more stable and the car becomes much more planted at high speed.
I loved how succinct this was, especially considering the breadth of the content! Great work!
This is awesome, more please!
I was ready to do some research but you’ve answered all my questions. Thank you
Thanks ,very educational.
Please continue
Love your Chanel!!! So awesome to be able to learn from an engineer with real world experience 👍
Yeet bout to wak a big mcwing on my hyundai getz
Getz sum wing
I'm proud of you!! I asked for drag stuff and you put the actual car I work on in the video. "YOU CAN NEVER HAVE TOO MUCH HORSE POWER OR AMMUNITION!! Bill Miller is king
the amount of info concentrated in this video is incredible, I feel like I saw 6 videos about aero in 1/10 of the time, congrats!
Excellent and well put together video man.
I'm Here! I know all the aero but its cool getting a refresh
I'm glad i watched your previous videos before going with my wing.
As ever....great, informartive video.
Thanks Kyle!
Great Video! Keep it up!
This was the best TH-cam video I have seen in a very very long time
amazing amount of knowledge in under 8 min!
amazing skill very very nice to watch tank you !
Your videos are amazing! There's so much learning. Thanks man. :)
Oval sprint racing is an incredible example of complex huge aero working beautifully!
Awesome, gives me encouragement to go sick on the khanacross car!
That is a very old photo of my MX5, it was also the first time I met the maker of this video! Thanks Kyle!
Great , Easy to understand video !
This was super interesting and intriguing
Hello Kyle,I was wondering if you could do a short video on blown diffusers?
Excellent video! thanks
Glad to see solar cars as examples in this video
Definitely need this video since I plan on taking my nonexistent car to the track.
imsa rx7 spotted on turn one off the main straight. ooft what a beast.
I kind of chuckled that you mentioned dragsters at the end... They really play by their own rules. A single top fuel dragster makes more power than the first 5 ROWS of the Indy 500! They accelerate faster from 200mph to 300mph than most race cars can accelerate from 0 to 100mph. At the starting line, the clutch is intentionally slipped to allow traction. This slippage burns off over 1000hp AT THE STARTING LINE. The engine isn't even at full throttle at that point, and certainly nowhere near peak power rpm.
Dragster aero doesn't follow the rules of anyone else. If you told a crew chief that you could give him an extra 300hp worth of traction at the starting line, but that it would cost him 3000hp of drag at the top of the track, he'd take it in a heartbeat.
Top fuel is insane. Insane speed, insane acceleration, insane BUDGET! Rebuilding an engine after each pull? No problem. Just gimme 40 minutes and 15 trailers worth of material. O.o
Very awesome content!
3:23 that is one Biggass wing.
It probably could drive upside down at like 26 mph
I added a high rise spoiler to my Honda Prelude just for looks. Although I got a spoiler I knew was functional on the car it was designed for, I didn't expect it to do much other than add some stability to the rear of the car at high speeds. I was pretty surprised when my rear tires stopped squealing while taking certain turns that I would frequently drive in the valley. It seems that the spoiler I have on the car actually helped at speeds as low as about 50mph. Regardless, I only really put it on for looks and will be going to a chassis mount spoiler once the car is closer to being ready for the track.
Your buggy is looking great, I'd love an update on that.
Great video and explanation, especially to newbies like me :)
About venting the engine bay, can you advise where are high pressure and low pressure zones?
From the car you were showing in the vid, low pressure zones are the front half of the bonnet?
I love your vids Kyle !! Maybe we can learn about the Air entering the engine and intake tract dynamics !!! I get to spend a lot of time on a blower dyno and it’s comical how little is known there.
This is the video I've been waiting for!!! Thank you so much!
If I want more downforce primarily while cornering how would I go about that, is it just a shark fin down the middle?
Ayyyyy the sydney moter sport park I was there!!!
Please talk more about Fsae aero!
really intresting Topic ^^ what could make an ae86 trueno coupe and hatchback better. I mean with lower drag i guess
Surely do more for like dirt rally and downhill racing
thanks!
I think that crazy aero time attack cars looks so good
Xantteboy it's beautiful
In 2 years I'm going to study aerospace engeneering, hope being able to work in racing teams and designing supercars helps me modding
Hi,
Could you explain a bit more about engine hood/bonnet venting, best places and the area near the windshield
Thanks
I'd like to see you discuss more about the effect of fins, such as found on the 1960 Chrysler Newport coupe (as it is my understanding they were wind tunnel developed)
I’m one that is definitely more comfortable with high speed oversteer than understeer. I enjoy your videos, I’m going to start playing with some new ideas inspired by your videos.
id like to hear more about day to day use of low skirts (combined with an underbody ofc) that may scrape but should last
Can you maybe do a video on the sheet metal “drag wing” boot extensions and how they work and compare to a normal aero foil type wing
Tthis thing got me more confused but you still have gained a subscribe
Great video and channel by the looks of it. Just subscribed. What is your background? Mech Eng and FSAE?
Your channel is superb. I look forward to binge watching all of your vids, as I know nothing about aero but have always been interested. You really know your stuff and are great at explaining (even I'm starting to understand, and I'm thick as $%#@!)
All right son...its time to have the talk...on aerodynamics
My favourite part about time attack is the sheer variety of vehicles applicable, never expected to see a time attack s chassis especially considering they’re known for the opposite of grip
Hey Kyle I wanted to ask you. What effects does a sunroof and side window wind deflectors or sun visors have on air flow?
Decent content! I need to add some downforce to the back of the car as it gets squirrely under high speed breaking! I have a standard impreza rear wing but think adding some rear diffuser would help, can you advise if just adding a decent bespoke rear diffuser up to the rear diff will make any difference (of course subject to angles and all that jazz) or if I need to flat bottom the complete underside of the car to feel any effect? PS car is used for fast street/ track use.
This is great! I know this is for race cars but in your expert opinion, do you think air dams or front splitters are worth it on street cars?
Your articles are always very clear and informative, dealing authoritatively with topics often ignored or dealt with superficially by others.
Maybe you could slow down you delivery a little as sometimes I can't keep up with you on complex issues.
And thank goodness there is an absence of the excessive mock friendliness and 'humour' which make so much of TH-cam almost intolerable.
Keep up the good work - your channel is excellent!
mine are only for fuel milage improvements at highway speeds.so far minimizing the "parachute" effect underhood has made the largest mpg gains for me.but i rarely go over 65 mph too.
Kyle - loving your knowledgeable and informative presentations but,, can you explain one thing please - at 02:24 - is the skin-tight suit helping with her boundary layer air flow?? I'm sure that there's more than a few of us who'd be interesting investigating this situation more closely - keep up the exceptional work
So for my needs a moderate wing, splitter and underbody would be preferable. Got it
Next time you come over to a drag race we got to get in touch!!
I made the video at 4:56 :)
Mark Collingwood same here 4:15 and 6:15
@garyr57@gmail.com
Me also🤣@ 7:04
1:46 Oh my goodness, that bridge looks extremely familiar to the one crossing the Theewaterskloof dam, in South Africa. Even the road sign and numberplate seems like what you would get there. If you could clarify it to me I would be soooo happy. Oh and great video by the way.
The 2018 WRC cars have some pretty interesting Areo because of the rule changes in 2017. Pls make a video of the areo on WRC car.
I’m gona try the flat floor as you suggested. Assuming the rake in and more aggressive rake out creates a venture effect? Sorry I find the science behind the areo fascinating, al I can picture is an old school carb in how it works.
Hey Kyle, can you do a video specifically on rally cars areo and when they go off jumps
Nick Currier I think it's because, they have to find a balance, for their best time. If they slowed down, to the point their tires don't leave the ground, then that will ruin their best time. But if they go too fast over a hill or jump, that they not only leave the ground, but go so high, that they also break something, including themselves, when they land. And or, they land off course. I think it's all about how hard of a landing, the car structure, suspension, and occupants can be ok with, an how much of a risk the driver is willing to take, for the best time possible.
Not only is the speed over a hill is important, but how you leave the ground, and the front-rear downforce bias, will effect how you land. Braking or closing the throttle, before the hill crest, and or, more downforce in front, will make you land more nose first. Closing the throttle, then spiking it open before the crest, leaving the crest while just accelerating, and or more rear downforce, will make you land more tail first. It's best to land with all tires level, with the ground on the other side of the hill. And leave the hillcrest straight, not turning, or you will land crooked, and may loose control.
If you know the ground ahead, seen a glimpse of it on approach, or you have co-driver with notes, then that's how you know what angle the ground is, on the other side of that blind hill. But if you're new to track or road, and can't see, or you just don't know, then go slow enough, that your tires are still touching the ground, even with the suspension fully extended, because vehicle like cars, can't stop, if their tires are in the air. And is your downforce strong enough to keep them touching the ground, at a certain speed?
Nick Currier I'm no professional. This is just my guess.
I'm sorry. I read "when they go off jumps", as "why they go off jumps"....
theres some crazy shit about this topic. the later year group b audi quattro was designed so that all four wheels would even out in the air and bring the car down in a controlled way im pretty sure, check that out dude its an awesome topic.
They also shift down then up to shift the weight around, helping them stay straight when jumping
Your opinion, what can be done better at a Nissan Juke Nismo RS to get more downforce in the lower speed sector?
Made the video! 4:15 and 6:15 baby!
I never got the claim that more people are more comfortable with understeer, probably because I learned to drive in snow and oversteer is always preferable in the snow since you can use power to push yourself out of a slippery corner rather than simply sliding into a tree or curb.
Exactly
You can also countersteer, whereas with understeer you're just going straight on no matter what you do
I used a semi-science method of designing my Aero on my kit car. Waited until it rained so there was plenty of spray. Got the wife to drive past me so I could see the air flow in the spray and photograph it. The back of the car always got dirty very quickly. The photos showed that I was pulling spray off the road in a vortex behind the car. I made a second diffuser wing which fitted below the existing diffuser wing. Much cleaner rear. The same spay/wind tunnel showed a much cleaner air flow at the back of the car, lift a plume of spray in a laminar method rather than the turbulent flow I had before. No idea if it made any difference to downforce and don’t care but it does keep the car cleaner.
Do you think that bolting a box fan onto the rear of a Honda Civic would noticeably increase aero performance?
I would love to see a basic walkthrough of your CFD software and workflow. Is that paraview?
what is an example of low pressure exits from the engine bay? I have hood risers on my track car and the entire rear of the hood is exposed about 3 inches
I've always wondered if it was worth it to add downforce on my little 60 hp trackcar. It's only able to reach 163 km/h (less now because I removed the headlights for cooling and front weight reduction) and on the track I'm the most used to, I already get up to 126 km/h, and I can already feel air resistance becomes high at that speed.
What should I do?
Can you talk about roof racks and the wind deflectors that come with it. I have a bmw e30, least aero thing on the road, any thoughts? I’d love to make the underbody aero
The exhaust of a Top Fuel car produces almost as much force as one of the jet engines from the Me-262 fighter.
Kyle,
Could you explain the characteristics of attachment on curved diffusers.
I understand the usual angle range linear diffusers use, but could you recommend radius for curved diffusers?
Thanks very much for your videos.
Depends on the car and how much energy the flow has as it enter the diffuser. That's something you can only fine tune in a wind tunnel.
When you say "don't box them in" at 5:50 in the context of canards, are you saying don't put endplates on canards, or don't block the trailing edge off next to the tire?
Can you do a video on inter cooler core thicknesses? I've read that air doesn't like to travel through cores that are too thick, over 75mm etc. Like in f1 the rads etc are usually large and thin. Yet in some drag cars (air to air) running crazy thick cores.
what about turbo fans on wheels from the retro rally years?
So you're saying Bosozoku exhaust is the way to go?
That car at 4:04, Seen it in person. How did you get that picture? This is very rare
Hi Kyle, a bit of an odd question but could a car running a large turbo/supercharger cause any kind of weird low pressure zones near the intake and if this could potentially have an effect on airflow across both the car and the intake itself? I was wondering if a high positioned intake might cause more aero weirdness compared to a low one which might potentially get less air and therefore less power or something along those lines, I'm familiar with the basic concepts of both aerodynamics and IC but not at a high level so just spitballing ideas and would love to hear your thoughts
Since you didn't get an answer here, I would ask a forum or even a reddit community. It's actually a pretty interesting question
0:50 Wrong. Professor Wiedemann who was part of Audis Aero Developement told us, that the Spoiler was only added for psychological reasons. The changes to the rear Springs and Shocks were the crucial point :D
The only spoiler works for increase speed if the ones you showing at 2:38, it's almost looks like an extention lip on the trunk, it only increase around 3-4 mph
A small lip spoiler on a sedan or a downwards facing roof spoiler on a wagon/hatchback actually nets a pretty significant improvement in drag
Would love to see you review www.simscale.com, esp. the CFD package, or at least just a video of your thoughts.
on a 150whp 1130kg track car (NC Miata), do you think there's more time to be gained with adding downforce or reducing drag?
Depends on the track. I'd aim for maximum drag reduction then a little downforce here and there where you can with little drag penalty. An airdam that is sealed and flat under with a nice efficient airfoil at a very low angle of attack (0*) would probably be all you can use at most tracks. Best time spent would be reducing drag though.
Maybe a nascar aero review?
I have a track-dedicated 350Z and would like to add a "smaller" rear wing but am concerned about the implications of doing so without also adding a front splitter. My Z has some aero mods but nothing major as well as significant weight reduction. Although power mods brought the hp to 290whp, in my mind it still does not seem powerful enough to justify big aero even with the weight reduction. Of course I could be wrong, but while a splitter might eventually happen, my ultimate goal with any mod is improvement and was wondering if a wing can help even if I run it without a splitter for a while. Ultimately, driving the car on the track will let me know how a wing improves (or not) the handling of the vehicle, but I'd like to have an idea of what to expect before undergoing to expense and effort. Thanks for whatever input anyone might be able to provide.
1 year later I still have the same question. I drive a fwd 60 hp car around the tracks. Topspeed around 160 km/h but I never reached above 135 on those tracks. Do little wings we see on the internet help providing stability or not? I'd love to know. Tx
What about aero for drifting? Do you know if anyone has tested what could be beneficial at those angles? As far as in a wind tunnel or a program? Been thinking of incorporating a diff cooler in the diffuser. Lol make the drag do some work if it's going to be there.
interesting - my take as always been that; A) the speeds aren't high enough to build sustained downforce. B) that any wing that was generating DF would stall as soon as it got sideways to the direction of motion
