I don't think the money's worth it, but I'm gonna test that shark fin thing.

 

even with extensive testing, they found absolutely MINIMAL reduction in drag or lift... i mean really cant be properly quantified in real life. i love my VG cuz i know it is helping even if INSIGNIFICANT but to be very honest the biggest reason is because it looks hardcore (and cool). we are all kidding ourselves if you think the VG and non-VG evo have ANY difference to improve a straight line OR handling performance hey ur right maybe VG will give you a .01 mph increase in top speed? maybe it will save you a few millliliter of gas per tank? hey i bet you a more effective way is to go on a diet and loose 15 lbs then to expect the VG to make any real difference.

oh come on! lol i love the VG as much as the rest of you but lets just accept it as a 'cool' piece and move on hehe

 

I am an airplane tech. This is probable the most correct statement made about the airflow cuase and effect of the VG. Most specifically "Without a wing it would create more drag at the top of the car but allow the air to close up better behind the car. " There is such a thing as parasitic drag, which the VG will cause. Sticking any item into an airflow will cause this, not eliminate drag.

Aircraft use VG to hold the airlfow closer to the wing to make the airfoil more effeicient, the same must apply to car as fluid dynamics are laws of physics.

Thats my opinion

 

the amount of air resistance it introduces could very well be offset by how much air it closes up behind. if you know your fluid dynamics you'll know that that it the most aerodynamic shape is an almond looking thing. this would be because as it goes through the fluid it seperates the fluid and when the fluid rejoins it "pushes" the object forward. that's the whole concept behind lowering drag coefficients and it shouldn't be ignored.

 

I have one one mine (with the wing) and only notice a difference on the highway. Not sure why you'd install it if you don't have a wing (it breaks up the air to work WITH the wing), but at highway speeds if feels like your back end is planted to the road.

 

my evo is just a gsr model. i would agree that the benefits of having the VG are worth the money. It just makes sence aerodynamically. not surprising that another peice of aircraft hardware is making it to our cars.

 

VG helps guide air to the wing to keep the *** down on high speeds. So it would be more affective if you have a wing...Plus it gives the evo more of an aggressive look!

 

I'll take 5%.

 

You got yours with the car.

 

So would it be safe to say that the VG without a wing would be slightly better than having no wing at all?

 

VG will still improve the downforce without the CF wing

 

It will help but not a whole lot. it is a part designed to work in conjuction with the wing, not without one.

 

no it will not. in the mitsu study of the VG on our evo's.... it showed it increased flow over the spoiler via the vortex to increase effective and reduce lift. mitsu 100% intended the VG WITH the spoiler, that cannot be contested. every windtunnel test they did was WITH the spoiler.

 

mifesto, where can i see this mitsu study? I agree with what youre saying. ive never come across anything from them on this though.

i read this back in january and i remember some people were laughing at it claiming its all BS. no its not B.S. but then i laugh at people who think this thing will help them drive like shumacher

now i laugh at the people who think this thing is still great without a spoiler... hey a 0.006 decrease in drag coefficient... in another words whatever lil gas you save, you loose once you go full boost for 1 second
