The Donut Wind Tunnel needs new items for us to perform "science experiments" - send us your best stuff or lemme know what we should put in it next - Jeremiah
I vote at the end of each Jeremiah video we get to see the aerodynamics of different Hot Wheels cars. You know you want it to happen. Just gotta poke Mattel the way they did Dodge. I am sure they would love the idea!
I once did 75 mpg in a Peugeot 206 over 250miles sitting right behind a big ol' truck halfway through germany. Drafting is an amazing fuel saver but the view gets a bit boring after a couple of hours
@@4nd3rzzon I mean trucks take for fucking ever to brake, like, with a small gap if you have the reaction time you'd be able to outbrake the truck in basically any other vehicle. like a shitty ricer honda civic with worn pads would be able to safely outbrake the truck
One of the other detractors to the tail car in a tandem is that the front car totally blocks the airflow to the trailing car's radiator, so the engine starts to overheat. This is why you see the cars switch places after a tandem.
I learned drafting as a young kid when we got our racing Go-Karts on the car tracks that were 1/2 mile dirt/clay, if you got out of line you went to the back! My pit guy was an engineer and after adjusting our body kits and plastic cone that deflected air over the steering wheel and leaning our seats as far back as possible to get our body out of the wind! It was fun in the limited modified and open classes because we were up over 100mph! So fun and so frustrating!
@@memosiuuuuuu8808 4 times a year. 2 at Daytona in Feburary and August, and 2 at Talladega in April/May and October. You can rewatch the full race at Daytona last week on NASCAR's RU-vid channel either today or tomorrow (whenever they upload it). Just a fair warning: while NASCAR superspeedway racing is a lot of fun to watch, recently a growing trend is that drivers are getting way too aggressive with it, which leads to massive wrecks. It's a lot of fun but also kinda stupid. Most people like it tho, but some don't
I never have spent a second consuming any NASCAR media in my life, but love formula 1. I’m interested to see why other people see it interesting. Not a hater just not a fan.
@@markcamenzind224 1) it represents the reality of driving for the everyman (not as much lately) whereas F1 is a billionaire's club. 2) It's loud and forceful as opposed to sounding like a little child crying for their candy. 3) Fights are fights, not little children crying for their candy (see Lewis, Toto, RBR, Maxi Pad...) 4) It's a sport that grew more out of prohibition, and therefore a more homegrown sport, than European borne F1... see why NFL, NBA, MLB are all more popular than the European sports they came from. 5) While NASCAR drivers who are driving for the top teams will win more often, it isn't like fffing Merc. American's don't give 2 craps about something quite so dominant. Keep in mind, our sports artificially inflate the number of games in a finals series to last as close to 7 games as possible in NBA and as long as possible in other "American" sports, as well. I -enjoy- NASCAR and Indycar 100000000% more than I -enjoy- F1 but F1 is can't miss. I still think Indycar is superior entertainment and F1 is little more than daddy's money vroom vrooming around (sans Lewis, obv, given his background). F1 is about wealth and opportunity whereas NASCAR is about actual talent (in the car provided... I'm not saying a NASCAR driver will outclass an F1 driver in an F1 grid. No sireeee that's not my argument). Hamilton is -not- as superior to his competition as the stats would have us believe. He's superior, but not as superior. Same with Schumi. 6) someone else can actually win.
I finished my thesis in nascar drafting this year and am now an aerodynamic engineer for an oem. Happy to see Jerry finally talking about this cool stuff
Once I learned about all the cool tech and tactics, all of the team efforts, etc, I began to appreciate NASCAR quite a lot. When I saw Blaney make a huge push at Daytona a few years back, when he was in the 21 car, it was actually very exciting. Even though he didn't place first it was a badass display, and he became the guy I root for out there.
The side-draft is actually when the front of the passing car gets to the spoiler of the other car for about half a car length. The passing car then moves a lane or two over so they don't get side-drafted themselves - or slow themselves and the car they're passing which is what was visually shown. That section could've been worded/shown a bit differently.
See i tailgate for the opposite reason. If there is somebody in the left lane matching speed with semis I get right up their ass to get them to finally pull ahead. But also for the same reasons, my truck gets better mpg at 75 than 55 and fighting huge side drafts from semis. Not to mention how stupid and dangerous it is to ride side by side with anyone on a 2 lane, let alone an 18 wheeler that will flatten even my pickup.
@@shadow105720 I love brake checking tailgaters. One time a guy almost flipped his pickup because I showed him that the Prius I was driving at the time could stop faster than his brodozer. Seriously, Priuses handle and stop better than you'd think. They just don't go very well.
What really makes NASCAR awesome, in modern era = Cameras. All racing, but especially NASCAR. Seeing the front spoiler cam really brings the feeling of just how fast 200mph is. In car cam and you can see just how hard those drivers are working to keep the car on path. Rear bumper is so great, seeing the chasing cars fine adjustments to stay in the draft, like a 500HP giant shark chasing down and chewing up the asphalt. The on track cams, like Jerry said "V-V-V-V-V-V-V-VVVVIPVIPVIP", and the debris flying off the track. That roar as they approach, and then silence after just as quickly. So bloody awesome. Stay gold.
I wasn't a NASCAR fan before this year's season. After having understood the concept of NASCAR, boy am I lovin it😍 P.s. I want this guy to be my physics teacher 😭😭😭he explains so well!!!!!!
Istg! I used to think it's just cars going round and round at high speeds but now I get it why people love it so much.. there's so many things working behind the scenes! It's a shame no one takes racing as seriously as they used to before
Lots of good information here! One thing that should be noted is how the tandem drafting works. Back in the early 2010s NASCAR had bumpers that lined up better with the Car of Tomorrow and it forced drivers to lock bumpers and tandem draft in order to win at the restrictor plate tracks. This wasn't really "bump drafting" as they weren't bumping, but actually the rear car pushing continuously on the front car. The "aero-push" also doesn't come into effect that much on the restrictor plate tracks where tandem drafting exists. The main disadvantage that trailing cars faced was actually overheating because the tandem draft covered the grill opening and caused them to run hot. So drivers would work with one in front and one in back for a few laps and then have to switch going into a corner and then they could hook up and keep tandem drafting. It truly became an art in the early 2010s and being able to time the switch and being able to tandem and switch in the shortest amount of time became a real skill set for drivers. Unfortunately when NASCAR introduced the Gen6 car the tandem drafting sort of died out because the bumpers didn't line up as well, and NASCAR implemented rules to forbid locking bumpers, which I personally dislike.
OMG wind tunnel on a model using Reynolds theory… straws for laminar flow. … fluid dynamics… you guys always amaze me of your engineering expertise. As a mechanical engineer I am impressed.
Could you even remotely imagine how INSANE NASCAR would be with even a tiny amount of active aerodynamics? Even something as simple as a variable opening in the air intakes?
Nascar better be sending you guys a thank you letter and some sweet perks because in 15 minutes you made Nascar more appealing to a wider audience than their own organization has in the last 30 years.
It was really nice to have the science of shake n bake explained to me by Tom DeLonge of blink 182 fame. Thanks for taking time out of your busy touring schedule for us Tom
Hey potential member of donut media. I love the content being provided by the media group and was wondering if a short physics video of (as silly as it sounds) how an engine... Turns off?
When you turn the car to off, Ignition tumbler your key goes into kills the eletrical power to your fuel injectors and ignition coils. With no fuel to burn or spark to combust the engine stops running.
The technical depth you get into is just fantastic. As an engineer I'm loving this stuff and it's making me appreciate NASCAR more than I ever thought I would.
I always love it when Donut makes a NASCAR video, it helps people who dont follow the sport or just casual fans understand the details. Keep up the good work boys.
9:35 I remember that race. My driver Truex (light blue car) was being chased by Jimmie Johnson on the last lap of the charlotte royal. This was Jimmies last chance at the playoff thats season so he tried passing truex and ended up wrecking both of them.
I can't wait till next year when they actually have to use suspension that you would see on a stock vehicle. Because my Toyota definitely has a solid rear axle
The IRS system they are going to is an attempt to emlimate wheel hop. Will be interesting to see who can use it to their advantage, that and the new transaxles will be the biggest changes i think. I can't wait to hear the sequential gear changes at Sonoma next year.
"Race cars like a NASCAR Cup Car are often already producing as much power as they can" iirc those things can do over 800 and are restricted to between 500 and 650 depending on the track
Producing as much power as they can doesn't necessarily mean the engine in turned to 11, it can also mean they're making the maximum amount of power allowed in the rules
I remember this when he said "Slingshot" Feel the heartbeat of my machine through this tight seat I feel every motion of my machine The race starts when two of us become one Bright lights fill my eyes You have no choise but to race There's no escape.

Anyone wanna create an F0 league where active aero, CVT transmissions, ABS etc would all be allowed. it’d be like a group B mixed with F1 very few rules but more interesting races!
Sweet wind tunnel build, but man the editor fubared that "aero-push" or tight condition showing cars getting loose on a road course. Love the content yall, and keep givin er the beans!
When i seen that small wind tunnel my first thought was ........."cant motorsport teams just use something small like this to test cars" then just make bigger scale replicas of that to save cost for a big "real" wind tunnel...............cause thats how mclaren got started Bruce bought a wind tunnel
