This is interesting because it does the opposite of the Difflow difusser, collecting rather than dissipating the turbulence behind the rear wheels. |
*There would still be turbulence across the entire width of the device behind it.That area is already a torture chamber for air,so it probably can't make matters worse!
*Water spray would likely be completely arrested 'within' the footprint of the device with only 'air' escaping through the central opening.A good reason for using it right there.
*If any sort of 'jet' is created at the central opening,the low pressure of the orifice might be communicated forward,inducing the vans side flow to 'hug' closer to the body,which could also help reduce the turbulence there along with its spray.
*It's way out ahead of nothin'.
