A 1:37.0 is pretty fast for something that you can unbolt the splitter from and go for a run to the shops in! What's everyone's thoughts on the car? p.s. That lap was done with the AC still on. Probably not a lot of WTAC cars doing that ;)
My comment on the car is... amazing. I was really hoping to see more details on this Supra when you showed a short clip of the bespoke diffuser in another video -- I am not disappointed. It's mega.
First of all, congratulations on your journey, you are such an example and inspiration for many engineers. I work with OEM product design (PSA part of Stellantis, and I'm moving to Renault) and after some years gathering experience maybe I want to give it a try at motorsport engineering, and of course you inspire me. About the project, it's a very nice project indeed, very complete. Congrats on the work of the design and also the composite company to get the manufacturering done. I wonder how was the suspension tuned and if they optimized it for the downforce and aero balance the car was going to have, and also how you setup the aero balance with the client (if that won't give any secret of your project). That's a topic I'm curious about, because from looking at the onboard (and this is just a guessing work from my part), the car seemed with too much corner exit understeer. Maybe because of the driving technique and that it seemed that the car could have more steering angle on some corners... But it appeared as it could have more entry rotation and power oversteer / exit oversteer. Maybe this rotation is something that can be achieved with driving technique, but I wonder how the setup and design were done in therms of the overall balance of the car.
@@JainZar1 it's road registered and once you removed the aero you could get away with driving it on the street. Could still get defected for many things on the car though so technically not legal
Awesome job by you Kyle and Jonathon! Time for him to start leaning on the aero in turns like T1, T4 and T7 where he could really make up a fair chunk of time. I'm doing similar speeds in a car on the same tyres and just an off the shelf rear wing. Can't wait to see what times the car can achieve moving forward!
@@chylld haha it's just a different feeling driving an aero car. You basically just have to trust it and turn in. I saw clubsprint car with less aero than yours holding 200+ through the apex of T1 so you've got it for sure! 💪🏻
Hey Kyle I'm a first year college student and its been a month i started watching your videos and they are helping a lot. I've joined an fsae team as well so it's definitely helping there. I just have a small request, if possible could you make 1/2 videos on a free software called Optimum Lap ? I'm not sure if you've heard about it but it's very intriguing and can be used to analyse vehicle data. I think you'll find it interesting too. edit : i found out you already used optimum lap in your huracan performante nurburgring video so great but would like to see more videos of u using it
Good videos. Would love to see more like that. Also just buy a small mic for interviews it will make the audio quality much better. External mic goes a looong way
I light up when i see these vids pop up! maybe after the dust has settled you could take us through some more of the CFD with this car since you developed it?
Awesome stuff, it looks like a damn potent package and can't wait to see where it goes next year. Maybe have two JKF aero supras there next year if the stars align. ;)
This is awesome, i race in gta in America. 2nd at super lap battle 2023 and my car is very basic. Plywood front splitter, nine lives wing, mcs remote coilovers and stock power c7z. Hopefully i can afford to have you design me a real front splitter to the rules of gta limited class. I left a lot to be desired there. Rear wing is probably fine until i get more front grip.
3d scan and custom design are a necessity if you want to compete at a high level. Shelf parts aren't useless but on a different scale of performance. I haven't tested this exact car, but in general, generic fitted parts are 1/4 or 1/3rd the downforce of custom though it depends on the rules and details of the car in question.
@@andrewbrilliant I knew the answer to this but, wanted someone to answer so the layman knew they could still effect an aero package based on generals rules but, as you’ve alluded to, the performance won’t be as optimised as it could be.you’re answer was perfect. 👍
I wonder how you generate front downforce without kanards, or ground effect takes care of that? I'm good with fluid dynamics for a mech eng., but not an aerodynamicist
Hey! I've been following your channel for a while now, as my goal is to work in f1 in aerodynamics after I finish university. I've read that F1 teams use NX or Catia . Which one did you use and is one superior to the other?
Hi Kyle, how did you find the dynamic rear toe on the A90? Does it go from toe in accross to toe out under compression causing bump steer? And if so how did you solve it.
amazing work as usual!! how much would cost to make me a similar project for my subaru impreza gc8? i´m a carbon fiber fabricator from brasil, would love to make a kit for gc8s!
Out of curiosity, do you still get substantial down force from a trunk mounted wing such as this one on the supra? I was always told it would just dent the body work and push down on the trunk latches. I'm looking at getting a wing for my project and was wondering if its worth the extra work to go straight to a chassis mount. Thanks for the content!
@@nizm0man Oh right, that makes it easy for him then! Unfortunately, my car isn't a supra and the engineers who built it didn't look that far in advance haha...
Amazing car and absolutely stunning drive by Jonathan considering it's his first major outing with the car! I feel like 2nd - 10th in class could've been as much as 0.7s faster if they had been luckier with track conditions. Also considering the car doesn't have as extreme set up as the other cars around it, it's also an amazing drive as well!
You need to get in touch with Ryan Tuerck. His Judd V10 Supra is a masterpiece, but I kept whining about how I wished he put a full time attack aero body on it. Help him out!!
hello kyle...a friend of mine who doesnt not care much about aero decided one day to say that "any aero works, even the ones that are flimsy." He then proceed to say that airfoils and front splitters dont need to hold a human." He also states that "aero need to be loose or else it will break under pressure". What are you thoughts on this.
Based on the 2022 World Time Attack Appendix A for car weight limits, the clubsprint minimum weight for the Supra is 1 387 kg. Don't know how much rounding up was involved in "car weighs one and a half tons".
I think this GR SUPRA MODS is from the BEST TIME ATTACK TOYOTA GR SUPRA. driven by the one ( JACKIE DING ) that Japanese guy who used to drive FORMULA one.
You should have rip that BMW engine out in put of Toyota super engine in then that would’ve been a true Toyota supra because it’s actually a BMW with Japanese body parts
They had to turn it down because to the trans? LMAO Are they full or is the supra really that shitty? My 92 civic is running over 400 on the stock 200k trans. Imagine having to turn down your motor because you bought a bmw.
