Default Any real time D.A. of pressure in wheel well?

I am curious if anyone has gone through the trouble of measuring the pressure in the wheel wells of a WRX at speed?

I am wondering if any benefit would come from a vent or duct in the well to give the high pressure zone a path to exit. I did a search on this site and came up with a brake duct cooling inlet incorporated into the fog light cover but information on what is taking place in the wheel well at various speeds was lacking.

If you have had the curiosity to measure the pressure versus speed could you share what was found? If there is no data I may hook up a pressure transducer to gather some data points.

If I had to guess, my thought is (as with most aerodynamic aids) the benefits of a exit duct may not be necessary until well past speeds encountered on the road... legally. Though I could be totally off and this may be something worth looking in to.

Any constructive information would be great.

Thanks!

I assume...and it's only an assumption...that it is pretty significant. The NB car runs those active s206,7 etc fender vents...just about every time attack car that rnd in the "do what ever you want class" runs a rear of the fender cut out for the tire/wheel well... And a lot of those cars run a larger louvre vent on top of the fender..

Is your WRX a pure race car?
