Out of the way of direct air flow behind the tire, how much difference can they make?

In the age of the aerodynamic revolution .... All the difference see what Viio had to say through CFD .. Viio great work I might add
PS. Sorry that the pics aren't attached.... since I'm new here it won't let me include any links .. but if you go straight to Viio's link its worth the trouble .. you also can find by searching Title "
Mudflap delete modelled in CFD "
Viio take heart, since vehicle protection matters to you the vortexsplashguards.com ones above that Tesla above (03-18-2012, 01:54 AM) mentioned lets you have best of both worlds -protection without the drag

The flow lines are a bit hit and miss - there is definitely much less turbulence (and drag) inside the wheel arch but the air is more turbulent behind the wheel now. However, the mudflaps appear to be creating downforce - check out the larger number of lines heading down to the floor with the mudguards on.
Now when we look at the "Cut Profile" through the mudflap section - this is more like it. Red areas are slowed down air i.e. drag. and there are a lot more of them. This is the view which made me ditch them from the car.
