With their talk of a helical track, I'm wondering whether it will be down-force that keeps the car aloft rather than centrifugal force.
I just hope that they use a long pipe and stay aloft long enough to demonstrate that it is down-force at work.

I don't see anything in that that says they are testing driving upside down, just that they'd like to but were testing other Indy Car myths.

From what I understand when I read that is they would LIKE to test that myth, but it doesn't say they ARE. As Cyber said, it specifically states, "In lieu of those ingredients, the team is tackling other subjects at the Indianapolis Motor Speedway this week for an IZOD IndyCar Series-featured show in spring." To me, that means they do not yet have everything needed to test the upside-down race car myth.

So which do you think is the single most requested myth ever? They mention that it's the inverted Indy car, but it also says "In lieu of those ingredients (the ones needed to do the myth), the team is tackling other subjects..." Sounds to me like they are NOT doing it. Pity. My father-in-law is a big MB fan and lives in Indy (even worked at the track a few decades ago). I know he'd have loved to see them.

Sorry 'bout that. I scanned the article in a hurry, having been hyped by Rose's post (naughty girl).
I wonder which 'myths' they have tackled.
Any ideas?

are there any indy car myths other than upside down? the only things I am aware of involve lifespan of the engine and tires. I wonder if they will be doing drift vs grip cornering...

The only one I can recall seeing on the old site was the one about a passing car having enough force to lift off a manhole cover.
But I don't remember that one being specific to Indy cars.

yes, that one is specific to the aerodynamics myths - though if SRRacing was here, he would be able to tell us exactly what body style is used on the street courses the myth comes from.
(when preparing for the race, the manhole covers are welded down - legend is that otherwise, the cars "vacuum" them out of the ground. I'm more inclined to think that it's bad enough putting tires over smooth steel, without it being smooth steel that can shift under the tire.

The Welding of manhole covers is to stop them shifting at all, braking or full thrutch ..... Having a loose cover is just not acceptable?....

right, but there's a myth there.

Off the top of my head, I can't think of another common myth, except maybe formula one versus Indy car arguments. Kinda dumb article. Mentions Indy car myths and vaguely mentions the one myth they apparently AREN'T going to do.

I would think that there must be a minimum diameter of pipe that would give a realistic result, as too small a diameter would reduce the downforce because the clearance along the center-line of the wheel-base would be greater than along the wheel-lines due to the curvature of the pipe.
I also think a helical track wouldn't definitively show that it was downforce and not centrifugal force that held the vehicle aloft, hence a pipe with sufficient length to hold a straight, inverted course for a few seconds would be the minimum requirement.
These considerations, and the lack of funds to construct such a 'rig' for just one episode would seem to preclude our seeing that myth tested in the foreseeable future, if ever.

Not to mention a multi-million dollar race car and liability of injury to the driver.

F1 versus Indie... "Who would be faster"....
The definitive answer is why test a Mini against a Super-car.
As both cars adhere to different rules on build/equipment/speed limits, they are in a different class altogether, so would not be a fair race?....
And if you took the restrictions away, F! wins every time...
If its just chuck a big powerful engine into something and quarter-mile it, Indie cars may have an edge, but when you get corners that go both ways, F1 takes them in style....
Yes EVERYONE wants to see the upside down F! car.
Here is a brief statement of facts that we concluded on the other board thanks to input from all race fans and those like SR Racing who know the exact state of play....
No one yet has a track that can handle that kind of speed required to sustain an upside down car... And that is theoretical build, not real life, because no one has done this yet.
No one who owns any track large enough is willing to build the track for what looks like a once only and possible end in tragedy stunt.
No one can get insurance cover to do this.
No one who owns a F1 indie or any other car like that is willing to "Lend".........
Purchase of such vehicle is beyond Beyond production budget by a few series budgets... its MILLIONS for even a second hand car without a working engine?...
Most importantly, no driver who has done F1 training is willing to even try doing this.
Not even Richard Hammond....
And no, dont ask me. I had a small scale lower class race permit, I aint interested in going "Bigger", I stopped at formula Third because the car had more power than I had [spherical's] and I know my limits....
Above is/was the state of play last time I had a look round at the possibility....
Of course, come back next year and read this thread to see if anything has changed?... But the F1 season has now ended, there are STILL an awful lot of Hangovers in Milton Keynes (Home of Red Bull) and testing is over untill after Xmas.

forums.speedtv.com/threads/11909-Mythbusters-to-tackle-IndyCarThey are testing 3 "myths": "1: Can an Olympic sprinter out-accelerate an IndyCar from a standing start? (possible stealth test for standing starts? ) I would expect up to a few MPH, yes, but I think the IndyCar'll take over well before the runner's top speed is reached. 2: Does a driver really lose 10 pounds of sweat in a three-hour race? (given the amount of sweat I emitted in my vintage formula days, and my street stock races, it wouldn't surprise me) 3: Do the underbodies of these cars production enough suction to remove a manhole cover? (as noted above, already spectacularly confirmed)" In 2009, a brick from the "yard of bricks" was sucked up on a practice lap at the Indy track.
