some create drag and some do not.

just curious what your aerodynamic experience is? I know I have little to none but everything I read online except for what you type says a spoiler/wing is about controlling drag but not reducing. from wiki to this site everything I find about spoilers says they create drag.

after some reading I am just as confused as ever. from what I read most spoilers will create drag but then again most spoilers we see today are mainly for looks.
I'm an avionics engineer... kidding, just mechanical.I am not an avionics engineer or anything like that (though I am a software engineer - so different field for sure but still of the engineering mindset).

To my understanding, the content in this thread appears to be correct. That being said... aerodynamics is extremely complicated magic. It can be fairly unpredictable. So I'm not sure if some of the "rules" of wings vs spoilers can always apply.
Just curious what you aerodynamic experience is mcglsr2? Just trying to get a feel if you do this for a living or just did some reading and cut/paste?
If I am not mistaken isn't there two types of drag going on with a spoiler? There is the drag that is created just from the wind hitting the spoiler(similar to the force you feel from the wind pushing your hand around if you hold it out the window at speed)as well as from the pressure diffrerence it creates behind it? A wing does not have as much of the drag created from the wind hitting it and can reduce drag by guiding the air but a spoiler like on the top fuel rail car is not going to do anything to increase top speed. I think a spoiler like That creates the force pushing down just as much from the drag of the air hitting it as much as it does with the pressure difference between them.
I think to say that spoilers reduce drag and increase top speeds just is not always accurate. The articles I posted above talk about how they control the drag to increase down force but they do not say they reduce drag.
this article talks about the wing creating some major drag but also some major downforce.

No worries, I thought that was my issue too.yes please ignore me going on 48 hrs with no sleep.... just went back over it and saw the parts I missed.
I'm really confused.
Scott, it seems like you're arguing the exact point that mcglrs is making.
Wing creates downforce with a consequence of drag. The idea is that positive of the downforce remains larger than the negative of drag.

I have never seen two identical cars with only a spoiler racing but if you have a link to the vid I would love to see it.
again reading the articles I am not sure if they are confused or you are.
