Anyone know if this this wing will help at all decreasing rear lift on the Civic EG hatchback chassis?

 

i have one on my hatch.. dont think it does much for aero, but it looks nice

 

It is supposed to smooth the air flow off the top of the car, reducing the amount of turbulence at the back of the car.

There you have it from a seasoned veteran....

Yeah, but does it actually work?

I guess a bit primitive test could be to drive in the rain at normal highway speeds, and see if the rear window gets covered in water/dirty (like it does stock). If the rear window doesn't then it means there's no turbulence behind that car and the wing work.

Might sound like a dumb test, but in all the coupe chassis I've previously owned, the rear window never got wet or dirty when going at normal highway speeds when raining. In my EG hatch the rear window gets dirty in no time. This have to happen due to turbulence behind ther car.

dirty19: Care to try?

 

I have thought about this as well with my EF as i now see alot of kids running around with the wing kicked up by adding washers.
Aero advantage?

 

Id try but theres no rain around here and none expected until winter time.
Secondly my car is far from street legal.
If i get pulled over the car will go to jail for sure!

 

I thought the original question was does it reduce lift.

What speeds are you going that you can actually feel the back end get light? I personally don't think you can go fast enough on the street to get lift on the back.

As for the dirt/water gathering on the back window that is normal for any hatch back/trunk lid that almost does veritcal. The air as it passes over the trunk section will start to swirl/eddy and cause that to happen.

You need VORTEX GENERATORS!!!

 

Geez why didnt you say so ... i happen to have a dozen of those vortex things laying around in my garage. LOL This may be a tricky one to solve then!

This is for track use going 100+mph.

Yes dirt/water gathering on the back window is caused by turbulence behind the car, typically for hatchback chassis.

Turbulence creates lift. So if the Spoon duckbill wing keeps dirt/water from hitting the rear window, that would mean the turbulence behind the car is removed, which again would decrease lift. Yes?

Vortex generators actually don't do much at all:

"Application of the VGs of the optimum shape determined through the abovementioned analyses to the Mitsubishi LANCER EVOLUTION showed a 0.006 reduction in both the drag coefficient and lift coefficient."
