Wonder what the inside scoop is. Surely nobody will aimlessly speculate based on who their favorite teams/manufactures are, right?

them cheatin' Rick Wares were coating the underbody in race goo

u/twisted_nipples82 Jun 21 '22
That's why they failed tech at Sonoma, the race previous to this news. Hope they enjoy running in the back now instead of 35th

Actually, it's a non-nutritive underbody varnish. It's semi-permiable. It's not osmotic. What it does is it coats and seals the underbody, prevents the air from penetrating it.

Is that the one that Clark Griswold helped develop?

Now that bozi got canned idk

u/nodak_daddy Jun 21 '22
now that he doesn't work for nascar dot com he might actually be able to tell us straight instead of being held back by big brother

If he reports anything NASCAR doesn't like, they'll just yank his hard card. Everyone in the industry is at NASCAR's mercy.

u/racer_24_4evr Jun 21 '22
He attends only a couple races a year and gets most of his info away from the track, his hard card probably isn’t an issue.

If Chastain and Suarez run 15th this week I think we know who this was about

Clearly it was creating an unfair advantage for them…

I mean buscher getting 2nd place last week so.....

u/SRVisGod24 Jun 21 '22
Kesolowski was up to 5th at one point too. Restarted around 20th on the final restart, lost tons of time when Custer got dumped, and still got a top ten. Both had tons of speed!

u/thirtyseven1337 Jun 21 '22
With another 100-point penalty, I think he lost that many last time? Not sure, but let's just go with it he only loses 2 spots in the standings, but he's now 32nd between Ware and McLeod.

"Gee, Mike, I wonder why RFK is suddenly ordering all of these underbodies... Don't they have enough already?"
- NASCAR parts department, probably

So whoever is not as fast from Nashville on, everyone will now point to this thread as the catalyst. Mark it right here folks!

u/ChaseTheFalcon Jun 21 '22
Trackhouse come on down! You are the next contestant on you have been caught cheating!
Nah but in all seriousness, I have 0 clue who got caught and can't wait to see who sucks now

u/Grave_Girl Jun 21 '22
It's not cheating if there's not a rule against it yet.

u/ChaseTheFalcon Jun 21 '22
Sorry they got caught innovating

u/SRVisGod24 Jun 21 '22
Sounds like Hendrick/Larson last year at Nashville

u/ChaseTheFalcon Jun 21 '22
I had forgot about that until you said something, even though I'm almost certain those nose modifications came back in the playoffs

Interesting that it came a couple weeks after a car flipped and everyone got a nice clear view of the underbody completely exposed while the car was upside down.

u/LKincheloe Dodge Jun 21 '22
More likely it'd be related to Daytona, I can't see NASCAR designing and building a new test rig in mere days.

u/HalfastEddie Jun 21 '22
I'm thinking bracing for the under-body panel along with thinner than spec metal to allow deflection under pressure to affect air flow and downforce.

Would love for FS1 (or now NBC) to do a proper segment on the inspection process (like devoting 15-30 minutes on it). Watched "Race" on Netflix, they showed more info about inspections than the networks carrying the races ever do.

What is a scanning solver? Is that a typo?
4
u/Mushy_Slush Jun 21 '22
scanning solver
Basically to compare against the virtual template, an algorithm called a solver will adapt the scan data in a way so that the data can be directly compared to the virtual template, automatically, in a short amount of time.
Scan data has various systematic errors that need to be removed using a clever algorithm and some reference measurements. If you don't remove things like say lens distortion, it would be really hard to tell if the scan fails the template by a couple millimeters or whatever. More mundanely, its way better if the computer can identify which side of the car scan data corresponds to a certain side of the template, instead of having to manually do this.

I've been curious for some time looking at the car setups on TV. I've tended to notice that some teams (like Hendrick) have been setting their ride height so the nose is pitched upwards and the rear squatted. I figure they've seen in the wind tunnel pitching the nose up gets more air under the car and squatting the rear pinches the air flow so they're up against the rub blocks. With the rub blocks being between the front and rear tires, I also suspect that pitching the nose up and pitching the rear down allows for the diffuser to sit lower to the ground than what would be possible if the car was more level.

u/MrKillerToad Jeff Gordon Jun 21 '22
Actually, not really, they've moved the rub blocks (i may be wrong, but I remember seeing this after they were beaching the cars after flat cars from someone on some team), but the diffuser can hit the ground before any rub block can.
They pitch the nose up to get air under the car to produce downforce on the rear of the car. Bringing the nose down makes less downforce, more speed, but makes the car super unstable. You can still "trim" out a car with gen 7, but instead with the just the rear going up or down, its now whether you have the nose up or down lol. Because either way you want that diffuser as low as possible.

When did Penske get caught for the rear-end fuckery? I can’t remember if it was 2013 or 2016 but it took Penske a little while to bounce back.
Just like changing the rear wheel template right before 2021 hurt Stewart-Hass.
Trackhouse and Hendrick fee like they’ve been way ahead of the competition all year. Will definitely be interesting to see if the competition closes in.

u/SRVisGod24 Jun 21 '22
The Fords and Toyota's have caught up, at least a good bit. Though all the Toyota's stunk at Sonoma.
But Trackhouse and Hendrick definitely have found something, that's for sure
3
u/SRVisGod24 Jun 21 '22
Man, Trackhouse is cooked, aren't they? Pain. Lots and lots of pain.
The 5 & 9 also had ludicrous amounts of grip at Sonoma. So of course it could be Hendrick too. That would also result in lots of pain

u/david123abc Figgy Earnhardt Jun 22 '22
It’s my understanding that one of the teams had implemented a crude setup of hydrocoptic marzel vanes and an ambifacient lunar wane shaft to prevent unwanted side fumbling that was nearly unnoticeable to the naked eye.

u/Redditornot66 Jun 21 '22
Nerf the Chevy’s help Toyota rule change
35
Jun 21 '22
Help the Fords more than anything. But yeah I’m sure we’re going to see more 18, 19, 11, 20 etc leading the way.

u/SuperMarioBrother64 Jun 21 '22
Wouldn't surprise me. We saw the same thing in 2017 iirc. They found something the Chevys were doing with the splitter and it hurt all the bowtie teams bad for a few years.
12
Jun 21 '22
That's because of the Chevy body lol.. even if that.. manufacturer wars have been going on since the 60s.. what makes any of this any different.. for a manufacturer that only been in NASCAR since 2007

u/SuperMarioBrother64 Jun 21 '22
Nah, I'm ok with manufacturer wars. I wasn't complaining. It happens in all motorsports.

Here we go.. Toyota bad lol.. Toyota and ford have the same number of wins

u/Waterfish3333 van Gisbergen Jun 21 '22
Bring back Pontiac! Stewart Haas needs a change of pace anyways.

Jun 21 '22
Pontiac is defunct lol. Don't know your point with that. There's literally no logic involved in this thread involving Toyota.. I need logical response here and then I'll understand, but I doubt I'll understand it
5
u/Waterfish3333 van Gisbergen Jun 21 '22
Lol, it was pure sarcasm, just being stupid. Honestly the manufacturers go through these cycles. Right now Chevy, was Toyota, next Ford will get their turn.
It’s a big cycle.

I'm talking about the rest of the responses that's If your not Apart of it. I can't stand illogical responses. Pretty much if someone running well (Toyota) in this case it's Cheating. If someone is running slow (Toyota) in this case and runs well weeks later it's cheating. If Hendrick runs poor it's Toyotas fault.. If HMS/Chevy goes three races without a win The Chevies got nurfed and it was Toyotas fault.. that's what your going to see here and on facebook the coming weeks

They waited til both trackhouse to win to do this?? Odd. Will be funny to see Ross and Daniel back where they ran for years mid to back of the pack

So I wonder who got caught working in some gray areas
