Time Attack Supra Gets CFD Aero Analysis w/ Verus Engineering! - Project TA90 #37

[@WyFoster]

When your aerodynamicist has an SR-71 as a desktop background, you know he knows what he's talking about.

[@JackieDing86]

*FACTS*

[@josezamora9450]

Don’t forget the friendly bear..

[@sepg5084]

If your aerodynamicist actually has a car as a desktop background, now you know he really knows what he is doing with your car.

[@dbrad32]

So glad I found this channel, just the engineer you introduced us too gave me all sorts of possibilities for my AMG GTR build. Ive now watched several of your supra build videos, GREAT JOB man...

[@racereadypowerhouse]

This is the KZbin content I dream of! 🏆

[@IntelEcoHD]

Love the nerdy stuff Jackie 🤙

[@Pollin970]

This is actually really cool to see this side of racing. You always see the cars putting down times on track, but you never see what goes into making them do so.

[@JackieDing86]

Yep exactly! A lot of glory goes to the drivers but the engineers and designers behind them deserve a ton of credit as well.

[@ciello___8307]

mercedes F1's youtube channel actually has a lot of great engineering videos. Really cool stuff

[@michaelpan7737]

Finally!! We finally get to get more development on aero. And Happy New Year Jackie!

[@KeenanStyles]

Happy New Year from Tokyo

Cool of you to show this 👍🏻👌🏻👌🏻

[@Q8TwinTurbo]

Great video Jackie. I personally got some good information. Can't wait to see what to see your aerodynamic modifications and outcome. Good Luck.

[@rickhouston2144]

That CF dummy joke had me rolling

[@JagerRacing]

Those guys are great, lots to learn from them. I visited them in 2020 and can’t wait for them to do some mustang stuff.

[@bobbyrios2k223]

This is rad to see, thank you for filming and showing us this!

[@gnohcrol2399]

Alex went super saiyan mode

[@ItsJustCams]

Oooo yes, killing dreams with science!

[@gloomyxyz]

I love how geeky this video is. Will you perform another CFD simulation once you have complete the revision?

[@JackieDing86]

Absolutely

[@carlosevfaj]

I love aero development

[@easygoingdude9990]

I'm actually quite curious as to how much the fake vents in the bumper and door affect airflow.. Happy new year you guys!

[@RandomlnternetGuy]

I always wondered how people properly dialed in Aero without just guessing

[@JackieDing86]

If you understand the concepts and what to look out for, you can get a decent chunk of the performance, but it wouldn’t be *optimized*

[@TimMatijow]

Most people just guess. I'm amazed at how people will buy a $3k wing and then don't want to spend the money on some wind tunnel time. I've seen people with all the right parts making a bunch of lift and drag. Just tweaking what they have can make a world of difference

[@gloomyxyz]

It just proves understanding what is happening and analyzing what needs to happen trumps aimlessly throwing money and parts at the car.

[@RandomlnternetGuy]

@@gloomyxyz beautifully said

[@jacksonzhong9298]

Wait so if runing Windows down Does opening the back of sunroof speed up the air and extract them out to clean up airflow?

[@JackieDing86]

No, opening the back window behind the roof will mess up the airflow going over the car and basically make the smooth airflow going to the rear wing turbulent

[@fazeobama8872]

and the more turbulent and dirty ur air is, the more the wing isnt gonna be doing what u want it to

[@tonycrispin]

This kind of stuff is so rad! Love it

[@edwinyurigattorno]

Saludos desde Honduras 🇭🇳 💪🏼

[@TheLeverMonkey]

Very interesting. Would love to see the s2000 go through the same process.

[@JackieDing86]

If the S2000 ends up becoming an all out time attack car, then it’ll 100% go through the same process

[@izzdin6228]

Now that is an info dump that i can get behind. So what's next? Mod the front endplates? Flexible side skirts? Or a completely redesigned front splitter.

[@JackieDing86]

Current idea is a new spec front splitter + end plate, then new side skirt and rear diffuser. Potentially new wing mounts too

[@izzdin6228]

@@JackieDing86 sounds solid, will look forward to it man.

[@RandomlnternetGuy]

@@JackieDing86 are there plans to take this back to aero analysis after the revisions?

[@JackieDing86]

@@RandomlnternetGuy we’re literally doing the analysis before we make all the parts, since making aero bits can get costly quickly

[@izzdin6228]

@@JackieDing86 also, watching the vid again, i can't help but notice the viper with meaty tires in the background in the beginning of the vid. Is it a road course car or a straightline car?

[@masashiiino6914]

Thumbnail reminds me of those "aerodynamics of a lobster" or "aerodynamics of a cow" meme ;).

[@JackieDing86]

Reminds you of that because they’re the same type of plots ha

[@michaelluttmer2486]

This was awesome to see and listen to how Verus breaks this down. I'm about to start going aero, may I ask what onboard data collection tools your team uses during driving that can aid in this kind of analysis? There's a bunch of tools out there, curious what your team uses.

[@ciello___8307]

Awesome video!

[@attesaawdlife8115]

Awesome vid bro.

[@rolandotillit2867]

The rear quarter panel is responsible for 40% of the drag on the car. Downforce works its magic at 80mph +

[@AndyLaurence]

Need to do some CFD on that desktop on the shelf. Cooling setup can't be good 🤣

[@mikepowers572]

Top content, keep it coming! Happy new year!!

[@R4BBITG4MING]

Since your car is scaned, can you get someone to turn it into a mod for AC?

[@JackieDing86]

It’s not impossible... would need a good modder tho ha

[@BitterCarGuy]

Happy New Years from Atlanta. When are you coming back to Road Atlanta?? I would love to see and hear the Supra

[@JackieDing86]

Hopefully with GTA in May or whenever they host the Road Atlanta event!

[@HeveOfficial]

What cfd software is he using?

[@garagecedric]

Great episode, im glad you shared the discussion. Will there be more cfd episodes or is the cfd budget blown now :) ? How are the rules regulating the floor design? Looked a bit rough in the model.

[@JackieDing86]

More will come! Will be designing on the model then running CFD on them before actually producing our new parts!

[@garagecedric]

@@JackieDing86 great, im looking forward to that! . Is the ground a sliding mesh or static?

[@michaelpan7737]

Is there anything you can do in terms of weight reduction? Maybe with aluminum arms, knuckles, and subframes? I know Wisefab makes a knuckle assembly for the S2000. It'll definitely take out the unsprung weight out of the suspension assembly.

[@JackieDing86]

Aftermarket Knuckles and subframes are illegal in GTA Street class, so that’s out of the question. We’re already running all aftermarket arms with SPL on the Supra, so that’s already done

[@michaelpan7737]

@@JackieDing86 At this point, is bracing a good step forward to increase the chassis performance?

[@JackieDing86]

@@michaelpan7737 not really, I think most of the braces are really just extra weight, since the modern chassis is already a lot more rigid that our competition. Weight reduction is still the way to go, just need to figure out where to cut weight

[@michaelpan7737]

@@JackieDing86 carbon trunk, bumpers and hood sounds like the next step. And I’m assuming the OEM panels and doors are all aluminum.

[@michaelpan7737]

@@JackieDing86 And of course, wiring is going to account for a good amount of weight. Better packaging is going to significantly help given how much is already done to the Supra.

[@avengingeyes4041]

Great video Jackie Looks like you're gonna need aggressive canard wings That will give you better down force on turns so it won't make the front end go up, And some wheel spats For Less drag.

[@gremotorsports]

Make the fake rear fender vents real. Any pressure relief is downforce gained. Hell make them bigger put some horizontal slots in the white of the rear bumper to relieve pressure built up. Some fins on the taillights directing the air toward the center of the car might limit help with drag from the body decreasing separation. Just hypothesizing? Gurney on the ducktail?

[@TheBreakfastClb]

Do you have SLB COTA planned for this year?

[@jakethesnake1503]

Cool video pal

[@shonancheta]

YASSS!!!

[@dimos15]

Very nice thnx! Do you know what they use to scan the car? I guess you can use the latest iphone because it has a lidar sensor.

[@JackieDing86]

I know the newer iPhones have apps that allow for 3D scanning, but the tool used here all still more professional-grade 3D scanners

[@jurinout8665]

No correction software for accurate 3D scanning with the phone to assemble the scan right to the real object.

[@aswerty312]

So why not just run the verus wing? Or is their setup optimized for something else?

[@JackieDing86]

Simply put, The Spage SP012 single element wing we have creates a lot of downforce, and instead of taking downforce away by switching to another wing at the rear I’m looking to add more at the front.

[@jessechen998]

Hmmmm they used openfoam too?

[@93683409]

Yea cuz it's free :)

[@nathangamber9230]

Didn't think you could do a flat bottom via tunnel aero in SM

[@JackieDing86]

You’re not allowed to do an aftermarket flat bottom in Street Mod, no

[@ch_chone]

Your comments about squat when the car is at speed got me thinking... are you in a position to set up a daq system for 2021? You're at a point now where a chassis-mount gyro might be useful to you so you can quantify the angle changes that the car experiences in roll, pitch, and yaw. Better definition of the boundary conditions for designing parts.

[@kountersteermedia6321]

It's a good thing Alex studied engineering at McMaster...

[@hardcore19811981]

Look into bump rubbers...not just for keeping your suspension from bottoming out any more.

@18:19 Utter BS; aero tests form part of the emissions certification and as such are witnessed by either the VCA or EPA in Europe/America. There is no scope for massaging the numbers or using the most "optimistic".

Alex & jackie - safety first. Please use face mask & practice 1 meter distance. Once you caught Covid 19, than you'll stuck in quarantine for 10-14 days. Waste all of your time / plan in racing. . Good & informative video btw. 😊
