stock wing downforce?
Just wondering..., does anyone have data showing that the stock rear wing generates any downforce (or upforce!)?

It should be down force. I have heard that this spoiler is a working one and it helps at speeds over 100 mph.

Given that the spoiler has a symmetrical profile and has virtually no AOA, I wouldn't think that it would have much effect, even at 100MPH.

1. It isn't a spoiler. It's a wing. A spoiler is when it's attached to the car. A wing sticks up into the airflow.
2. Most factory rear wings do not generate any downforce... in fact, the only one I can think of off the top of my head is a 1969 Charger Daytona, or a 1970 Plymouth Superbird, but even those were 'set' to ZERO at the factory.... 3. It probably adds stability.... maybe.... - Rob |

Hi spoiler freaks, The first rule engineers have when working on spoilers for street cars is "First do no harm" So i'm guessing Zero force of any kind would be the right amount. Take care, BOBB

Mychailo,
yeah, no AOA, but it does have an effective cross sectional area. Should be able to calculate it and compute the drag associated with it and vector out some effective downward force... -Bill |
It is not a spoiler.

Despite the creative terminology, I think I understand what you're trying to say. However drag does not automatically equal downforce, though it can reduce speed, thus lift if there is any. Now as for calculating the effective drag, you can probably generate more just by sticking your hand out the window and holding it perpendicular to the airflow.

I see nothing in the dictionary that prevents the use of the word spoiler from being applied to the rear airflow modifier on the SVX. In fact the word wing generally carries a connotation of lift, which is definitely not the intended design when used on a car.

the wing is NOT symmetrical from top to bottom
it is actually an airfoil flat on top curved underneath i have heard that in the wind tunnel tests it is functional at high speeds, over 100, which i believe, althoguht the car in general seems to suction to the road more the faster you go |

I had the opportunity to watch my SVX at 100mph on the highway on Sunday... the rear wheel gap actually shrinks slightly at speeds over 80 so I assume there is usable downforce being created.
