I've installed Vortex Generators on my 2008 xB. They actually work! When I reach highway speed they actually such the drag back in towards the back. On the plus side, when driving on wet pavement I don't see as much road spray on the rear windshield. On the negative side, when I get behind a vehicle that puts up a lot of road spray, I get extra spray. Living in Washington state we get a lot of wet roadways, so I am working on a custom set of splash guards to minimize what I throw up behind the car.

OG mod, pics or it didn't happen

;D

 

haha vortex generators! pix please! does it actually get rid of the dirt on the rear bumper when it's wet? or is it just the windshield? i'd be interested cus it's annoying to clean on a white car.

 

Thats what rear spoilers are for on our xB's.

If you look an xB spoiler(or any SUV spoiler for that matter), they take the air coming over the top of your vehicle and direct it downward behind your xB, reducing the vortex/suction that is created by our vehicles as they cut through the air. This reduces the amount of spray that is "sucked" to the back of our cars.

 

Yes, pics now !

 

I'm not really a camera guy, but if I can find my daughter's camera I will take pictures of them while the car is still dirty so you can see the trailing edge marks on the roof.

 

What you've been waiting for.

Reminds me of the signs at parking lot exits... "Do not drive in reverse or severe tire damage will occur."

 

i used to rock those on my tc...i always said how i could feel and see the difference but everyone just made fun of me I still like em though even though most do not

 

i remember when I saw random cars puttin vg's on their cars and thought "evo wannabes" but I guess I was wrong if it actually works . Where did you get it from?

vortex generators re-energize the boundary layer of the air flowing by the contours of your car; so it delays flow-separation; which KINDA reduces drag.

However, the relatively boxy shape of the xB by itself kinda already negates this, though it might help a teeny bit by not creating turbulent flow closer to the rear-end of your car (hence all the dirt on your vehicle), but like I said, it's a boxy shape, so it will happen no matter what; the ideal shape for the rear end of anything flowing through a fluid is tear-shaped, (i.e. the 2d profile of an airplane wing).

 

nice addition
i was plannin on getting the evo vortex but haven't found it yet
now seeing this it's 2nd option
can you post more pic of close up view and distant view
thanx

 

Yea, that looks retarded.

 

Neato. Id give it a try for free lol. IDK how this would look in front of my spoiler though...

YES. I've been looking for something like this for my first-gen xB. Where did you get them? Are they paintable? What would be the effect of putting them on different spots on the roof or body?

Never mind, found the link above ;)

 

I'd like to try em, if they help with the back window. Can the OP please comment on rain driving. I dont have the rear spoiler and it can fracking annoying how quickly the rear window gets covered with water.

 

Ordering today, going to leave them in black on my black crush car.

 

As long as we're talking about aerodynamics, has anybody done an underpan or rear diffuser on an xB, specifically first-gen?
