    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 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.

    • @Camburger
      @Camburger Год назад +6

      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

      @kristjancebulj8162 Год назад +21

      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.

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.

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.

    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.

    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.

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.

      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.

    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.

  • @RobertHarridge

    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.

    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.

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.

      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
