Airtabs - do they work?

i would LOVE to see the actual wind tunnel demonstration over a computer simulation

even if you went by the computer simulation, i would expect a much greater fuel mileage increase because of the "no drag" created,

not 0.2mpg but a full 2mpg if not more

how much do they cost?

 

o, got my answer

 

Maybe we could hassle Mythbusters to check'em out, along with Aircell, Turbo3000, dual wheel covers, etc. Even if they did run the story, it'd probably just muddy the water even more, but we just might get some oh-so-precious wind tunnel footage. Think I google that right now.

 

wheel covers give you .17-.2 mpg.... I've checked the millage on this truck for 2 years on a dedicated run with the same load and the same fuel stops and when I installed the wheel covers my millage went up .19

it took less than month for them to pay for themselves in fuel savings. running solo would take about a 2 months, but the ones I got are the most expensive you can buy

So how much are they?

 

Properly designed and placed spoilers (front and/or rear) will actually decrease the coefficient of drag of a vehicle even though you may be adding something that "interferes" with the air stream. It is all about air stream management and the rear of trucks/trailers are extremely inefficient.

 

If I were to ever try the air tabs, I would want to get them painted to match the truck. Makes one wonder what additional cost it would be to do that after purchasing the air tabs. Especially for someone like me that does not have an automotive painting setup and I have never seen my truck color... Dupont Viper Blue Pearl Elite.... available in a spray can. The ROI seems to be getting further and further out.

 

the cheap ones like Schneider has

mine were $480 for all 4 with the air lines so I can check the tires without taking them off

 

Well, sure, and if you want them gold plated, the roi goes way out there! Haha. That's something to be considered, though the black ones match black plastic/ rubber trim items and usually don't look too bad bare. Btw,have you ever looked for that color among the model car paints in a hobby shop? Couple cans ought to do it.

 

one can maybe 2 of fusion paint comes in a blue may work.
