Vortex Generators
Ive read alot on the sight ECOMODDER..
Other Cf members should check it out..
There have been some extensive real world testing by members there and confirmation that they do work..
Any opinions?? Any real world experience?
Obviously one factory team..Mitsu believes they work and has published a 3 page report about the beneifits...I just read it!
Just wondering what the CF members have to say..?

A vortex generator is a series of small vertical fins or vanes designed to create vorticies to keep airflow streamlined over the trailing edge of a given surface at speed. Most aircraft have these on the leading edge of the wing to give a lower stall speed. for a car to have the same effect, you'd need to mount them somewhere forward on the roof. This would be most effective on FRC cars where the rear window drop-off angle is significantly steeper than the targa coupes.
the only catch is that by making airflow "adhere" to the body you also turn the car into an airfoil and at speed, this creates an area of low pressure over the rear wheels and lift
This is why many supercars have spoilers, wings, and air diffusers to creating downforce counteracting the "lift" of having a smooth airfoil lines.

I was informed that I should place the vortex Gen 4" behind the peak point on the roof to achieve optimal results.
That would put them on top back edge of the halo..
Any opinons on placement to optimize performance
Any opinions on best angle to set wing at..
Thanks

the Corvette does not need a roof spoiler for aerodynamics.
just the small 1" rear deck spoiler at 45* AoA. and proper alignment and good to go.
now if you are talking about a REAL WING, bolted to the frame, not the rear deck, then a 2" front splitter and extractor hood are needed for down force.
The wing AoA would be determined by how large wing and the Gurney lip is or if you have one at all ?
then weather you are on a (1) low down force high speed straights,(2) high down force high speed cornering (3) intermediate down force and speeds.
if the wing is just bolted to the deck lid and not the frame just put it level. any AoA may crush the deck lid.

J.R., sponsored by Pfadt, has a Vortex Gen on his Corvette roof (#240) that he's selling. you should ask him about the effectiveness.
