My Jeep is the same color as flour...lol. Are you going to add any to the sides of the Volvo?

On the Audi wagon, I was able to mount them even further back without interfering with opening the hatch. Like the Volvo, all 10 fins fit perfectly between the OE roof rails. Quote:

OK, Its only been a week since the VGs were installed on my Volvo wagon. Its still too early to tell, but my FE has pretty much remained the same...then again, my time on the open highway has also been limited.
It was raining and foggy this morning and I did notice something kind of unusual in the water mist behind the car while driving on the highway during my commute...two slightly visible, counter-rotating vortices extending from the roof area. My rear lip spoiler is still on, but the vortices still seemed to flow level with the roof height without being deflected upwards. The spoiler will be coming off in a few weeks, so we'll see it some downward flow can be induced. The next time it rains, I plan on letting my Wife drive while I sit in the back to observe them more closely. On another note, my co-worker has noticed a cleaner rear window on his A6 Avant. But he did tell me that it gets just as dirty @ lower speeds. Also, my Dad's VGs came back from the bodyshop this week. They were painted Mazda 'Silver Green' and the bodyshop did a fantastic job in matching the color. Total cost for painting 10 VG fins...two pepperoni pizzas(it helps having friends in the autobody biz;) ) They'll be installed soon. |
That would make a good picture. wink, wink, nod, nod.......

Ok, I'll open up some discussion. I find the VG stuff really interesting.
With just some preliminary info from the Airtab site, and going off memory, they discussed that there was a point when each individual Airtab being a certain distance apart, the vortex generation would be reduced. Reduced to a point where it wouldn't be useful. I'm paraphrasing. Could it be that the Vortekz generators don't produce enough disturbance in the air to generate enough effect to be useful? https://www.tracklab.biz/Tracklab/ass...Airtab9_sm.png https://www.pickupspecialties.com/gas...tekz_blue2.jpg |

Yeah that spoiler needs to come off, I can see at once the airflow gets disturbed too early, even after the spoiler comes off they might be too far forward thou without spoiler they might work.

SL8Brick,
Looks good. Have you had a chance to get any hiway miles yet? Phil |
