Hey guys,

My buddy used to own a Mistu Lancer EVO8. He purchased the vortex generator used on the MR version mostly for looks and also for its ability to add downforce. The part built for the MR was obviously custom to the EVO8. So he asked himself, "what if I split them up individually, and created guides so the fins are properly angled (otherwise they wouldn't work), for universal application on any car?"

The end result is below. He'd like to hear your opinions on this product. He has created packaging and guides with templates so the vortex generators are functional. In short, vortex generators reduce turbulent air and creates a vortex which falls faster, hence falling faster early enough to put more downforce on the back end of your car. Many forms of airplanes use vortex generators, as do race cars.

Anyhow, they stick on using really strong adhesive 3m foam tape. You can pull on them and they won't come off.

My apologies, i had to crop the images for the forum. I have much more detailed pictures.

What do you guys think?!

 

looks like a shark. but not too bad imo

 

Functionality - You get an A+

Looks - Not so much. They definitely fit the mitsu better than the Z. But awesome job on doing something no one else has.

-Acree

 

Ive read that they wont help the Z unless its matched with a High wing like on the EVO's....The Z has zero lift stock so adding those may hurt the aero without a high wing...I wish I could remember where I read that...

 

There was another thread on here a while back discussing these and they did some string testing on a Z with them; posted up viseos and everything. There are also universal stick-on vortex generators available already (link was in that thread).

Did your friend do any string testing with these on to see how they were affecting airflow? They look like they are mounted abit high; the ones I saw tested before were mounted at the top of the rear glass, which looked much better. I'll see if I can find the thread...

 

Functional yes but as for looks not feeling the "nipples" your Z now has.

 

Here's the thread:

pics and vids no longer work, but there's alot of discussion and the links to where to buy the vortex generators are in post #19.

 

i think your car looks like sonic the hedgehog.

sorry, good idea but i dont like how it looks.

 

Thanks for the fedback guys Yeah, they weren't designed for the Z. Like I said, it's more for universal application. I'll have to tell my buddy to look into string testing them. I'm really curious if they hurt the aero on the Z. It's too bad the pics and video don't work =/ I'll post back here soon.

 

Yeah, basically what the guy did was take some 6-8" lengths of yarn and tape them to various locations on the rear window and wing of the car; you could really tell the diff. in turbulence with and without the vortex generators. Then experiment with different amounts of generators in different locations to optimize airflow.

 

Interesting. Why at the edge rear window instead of the roof? I'd like to suggest this to my friend. He followed the specs of the Mitsu VGs, and just individualized them.

 

For the placement of the generators or the yarn? The yarn b/c it obviously need to be located behind the generators to see their effects, the generators b/c that's where they looked the best. I doubt it makes much difference whether thay are forward a bit on the roof or at the back of the roof or at the top of the rear window, but that'd be something else to test, I guess.

 

 

Well supposedly they have to be 100 mm before the flow separation line...according to mitsubishi. If you put it at the flow separation line you're already working with turbulent air. But technically on the z, the roof slopes very early...as i said it's supposed to be placed 100mm before the flow separation line, which would land them smack in the middle of the roof...but the VGs would look stupid there.

 

Hmm, I see. Yeah, I dunno if the other guy knew that or not or experimented with them at any other location than the one that seemed logical and looked the best. They DID havea positive effect in that location, from the vids he posted, though (might have been better, even, if they were furrther forward, as you say).

 

unless you're planning on using the top of your car as a spike strip to stop getaway criminals, dont you dare!!!

 

In a nutshell it looks like ****

 

I'm all about DIY mods, but don't like it.

Think about the way the Z already looks and the way the EVO looks....

 

They look like door stoppers.

 

The EVO forums must be having a field day on this thread.
