Stronger tyres

Chaparral and all car builders of the era.

I think they did that so all three wings ran in clean air, and im pretty sure the side force may be beneficial.

The wing on the Dodge Daytona was high because the trunk lid had to pass under it, nothing else.
It was attached to the fenders, not the trunk lid as is done today.

I just always assumed it was because Dodge in that era was pants-on-head crazy (Which is awesome).

:confused: in an interview the chief designer engineer tasked with the aerodynamics of the Daytona said that the wing was that high so that it cut into an uninterrupted flow of air and nothing else. Nothing to do with the trunk, apparently that’s a massive misconception. Hold on, let me find that article. (cool, but little bit offtopic, worth a read)

Here it is!

Didn’t notice the other two wings :stuck_out_tongue:

So yeah, that was a case of “The rules allow it, and it made us faster in our trials, so we are doing that”

And the height as you said is because of airflow. Although I am quite sure in terms of drag vs down-force, that wing was pretty bad.

Wow, Myth busted. I always believed it was that height just so that the trunk could be opened. Now I know better.

I did know it was extremely effective. I also recall reading an article in some Mopar magazine about restoring Bobby Isaac’s 71 Daytona (I think it was that one) to its racing state. It’s a really cool article I can never find when I want to.

well damn, I know when I build cars from that era in game, I always whack on a massive tall wings if I’m fixing it to the body and not the trunk (which I tend to), because of trunk clearance :joy:

but that’s because the aero fixtures in Automation have a set effect and don’t take airflow into account, because that would probably add about 5 minutes to loading times every time you change the size or position or type of fixture :laughing:

Same for me, granted I normally dont use the smaller wings at all… either I use the full on race style wing, the Superbird-esque wing, or one of the weird Japanese looking wings.

Ok. So it’s just a happy coincident that the trunk lid “just” clears the wing, you live and learn.

For what it’s worth, I also assume “being able to open the trunk” probably came up in the design decision process, so I’m sure it was also a consideration.

If you put the wing in the lid, it will touch with the rear windshield.

And if you put in the fenders, you need to make a space for the opening.

And, the high wings it was designes as it, because it was a era without any study about the interference of the body flow and turbulences with the wing, to work both (I’m not good explaining sorry :frowning: )

And a high wing, the centre of lift is very high.

Lift?

Yep.

Invert the wing, but the lift and the weight components, like the thrust and the drag, it doesn’t changes the orientation and position. It stills the same.

Downforce=negative lift.

Lift=positive lift.

(this, using the cartesian coord: left: +x; right: -x; up: +y; down: -y).

I’m used to CNC coordinates, x- is to the left, x+ is to the right.
I don’t think anyone normally uses “negative lift” to describe a wings effect on a car.

CNC machines or not, from the origin, the negative values of x will always be to the left of the origin and the y-axis when following the x-axis, while the opposite holds true too. Simple geometry

And that, Sir, is where you’d be wrong :stuck_out_tongue:

You can change the coords system axis, but it needs to be indicated.

At least at Engineering
