The main idea of getting the air to flow over the rear window is to increase the air pressure on it so you don't have a low pressure area sucking on the back window slowing you down.

Those are called air tabs. These are MUCH better since they have much less frontal area- all that frontal area negate any .cd gain.

Well that is really cool.

vortex non functional

vortex generators seems like a issue that will not die,,,,,,,,,,,i agree fully that along with the spoiler they create excessive drag and apply much too much down force................i ran vortex generators for three months they have about much use a a chromed dipstick

since I see a spoiler, you're going to generate more drag leading to worse miles per gallon. Here is the demonstration on how the generator was come about for the EVO and the window spoiler on the 06/07 STI:





As you can see, the rear window spoiler works better in getting the air where it needs to be. It is also measured by downforce seen here:



The EVO has 46.86LBS of front end lift and 9.68LBS of rear end lift at 90MPH, at 124 MPH it has 90.42LBS of front end lift and 18.7LBS fo rear end lift.

The STI has 57.64LBS of front end lift and 38.06LBS of rear end downforce at 90MPH, at 124MPH it has 111.1LBS of front end lift and 73.26LBS of downforce

So the answer is to actually get rid of your generator and your wing if you're trying to get better miles per gallon.

My latest experiment is Giant Zig-Zag tape..
It's new to me, but I think ZZ tape is a type of VG strip also called turbulator tape. Or, maybe it just works like dimples in a golf ball..



Got to take a few road trips this week to see if it's doing anything.

... dont mean to be confrontational, but i dont believe you. what was the application and what were the results? "not good" doesnt count.
