With you claiming they are not VGs, I'll pass completely.
For if they don't generate vortexes, I really don't see what they'd do ...
But VGs DO work.
I have glider dimple tape on the mirrors, A-pillar and top of the windscreen.
Car is noticeably quieter now - the V50 range is known for wind noise around the A-pillar.
The effect on fuel consumption is not measurable though - i.e. I simply can't single it out.
The dimple tape didn't do $h!t on the rear end though - so I removed it.
The dimple tape is too shallow (about 1/16th to 1/12th of an inch) compared to the boundary layer.
The gaspods look the right size to effect the boundary layer at the rear end - if they do something like causing vortexes ...
Variability in day-to-day driving is simply too great to test the effectiveness of your products. Wether it's over 2000 or 20000 miles. |
I will bet they work exactly as described herein. Diffusers basically whip the compressed air into the boundry layer air. I like that someone indicated boundry air here.
A proper down turned and vented spoiler just below roofline on back window would have done a better job but probbably wouldnt have gotten as much attn. But who am I to say, as I wasnt in thier wind tunnel testing dept.
