hello
does anyone feel the difference with the vortex generator on the roof?
should make some more downpressure,in higher speeds.so i was just wondering if you can really feel it?

I put one on, for looks, and I havent noticed anything from it at high speeds or normal speeds.

I think you can only see the difference in wind tunnel or stats sheet. I don't think you can feel the difference just by driving it around town or on the track.

I had a measurable increase in gas millage and the car is more stable windy conditions.

They help stablize the car when im about to take off into the air.

really??? more stable???so gas millage you drive more miles on full tank??
i allready have it on the vortex like two weeks and i really like it how it looks.

If this is true I may have to buy one due to the windy conditions here. Can you elaborate a bit more? Before/after the VG?

I noticed a difference down here in texas with the high winds recently and at high speeds a little difference in the handling.

Looks only!!! Had it for 3 month no difference.

All looks, no function on my car.

Looks only. If it betters the gas mileage then i would put one on every car I own.

I find this hard to believe.. but I would be interested in how you came to this conclusion.

First of all before we spout ideas on what you think it does.. you have to realize what it is and how it works.

It is a vortex generator.
Here is a wiki link incase you want to know more about it.
http://en.wikipedia.org/wiki/Vortex_generator

And an even better link in more plain english.
http://www.aerospaceweb.org/question...cs/q0009.shtml

So just to summarize it.. Vortex Generators do exactly that.. Create vortices that are positive in nature to control the flow of air and put more energy of controlled down force on the car.

In our Evo the Vertices that flow from the top of our roof.. spiral the air and then press in a smooth fashion on the rear wing.. Because of the Vortex Generator the flow is more constant and there is more energy creating controlled down force to keep the car steadier at higher speeds. Is it noticeable??.. i'm sure it can be but only if you're going like over 85mph - 150mph.. The higher you go the more it's noticeable..

It's really more of a gimmick as nobody here has the need to go that fast and turn..

Hope that lays down the Information smackdown and clarifies it for all of you.

Peace..

P.S. The gas mileage theory is wrong, as it would cause more downforce thus more drag thus less gas mileage.

i've seen stis around here with bootleg vortex gens...

Most of what you say is correct other than the comment about nobody needing to go that fast and turn and the comment about gas mileage. Many people on EvoM take their cars on the road course and take turns at high speeds. And regarding gas mileage, it increases pressure on the backside of the windshield which will essentially push the car down the road. Odds are that gas mileage will remain the same as the additional "push" and the additional drag on the wing will cancel.
