Susanne, I have never tested them nor have I claimed to. Maybe there is a misunderstanding in something I have said. If so, please point it out so that I can clarify.
There is no where that this has been established..... Quite the contrary. And criticism is only coming in from those who have not tried, or read our website.Yeah, we already established these things don't work as advertised ....
I didnt say I tested them. I was going with the results that others had reported. So no, I did not say I tested them. You have put words in my mouth. It kinda sounds like you were taking something out of context.You had me scared. I thought I had you mixed up with someone else........ But, here is your quote to which I was responding:
There is no where that this has been established..... Quite the contrary. And criticism is only coming in from those who have not tried, or read our website.
I am very careful, and very good, at making sure that any claim made has basis.
Indeed........snake oil..
As we are on a VW forum, I wouldn't limit myself to Detroit, even though I was born there. That being said, where did you get the idea that we are not working with auto manufacturers. Another assumption?Any car manufacturer that is subject to CAFE requirements would pay a healthy fee for even a 1% fuel economy increase.
Suzanne, if your claims were real, you would be the toast of Detroit and quite wealthy by now. Perhaps it just hasn't occurred to you where the real money can be made?

Yes, I assumed that you would be shouting from the rooftops anything at all that would add (sorely needed, IMO) credibility to your company.As we are on a VW forum, I wouldn't limit myself to Detroit, even though I was born there.

Now that we’ve established none of the criticism here is based on testing, but rather, it looks to me like you are just joining in on some fun….. Let’s get serious. This is one of the most viewed threads on this forum. I don’t think the viewers are all looking for fun and games. I think there is sincere interest by forum members in what GasPods are and how they work on VW TDI vehicles.Yeah, we already established these things don't work as advertised....
Underline mine.Bill - 40X40 - oldhifi, hutchmanhd, MikeMars, my Ophidiophobia friends (that means fear of snakes)…. The best way to overcome fear is to take the GasPods in your hands, install it on your car, and prove it to yourself….. You might find you are so excited by the results that you’ll have a new line…. Hey baby, can I pod your car?
Now, I'm starting to have too much fun....
AeroHance is registered as a vendor. I think it was a requirement of our participation.Susanne,
Would you be interested in becoming a registered vendor on TDIClub? Given how much people here are driven towards fuel economy, if the gains you are claiming are true, this could be a very lucrative venue for you to participate in.
Bill's suggestion of donating some products to the club is a good one. They could be sent to members who are interested in doing real world testing and either confirm or bust the claims that have been the topic of discussion for quite some time. Once we get past that little hurdle, I think we'll be moving forward.
That has been said several times already.These have been on the market for over two years. If they were as good as they are claimed then why are they not more common. Word of mouth (from real people) would spread.
Plus, if this type of product worked then we would see the same type design on new cars.
You are welcome to pursue 50 tanks of tracking with, as I'm sure you've already tracked without.... And the sites you are quoting include only posts by individuals who discounted the product out of attitude, and have not tried the product.show me a 50 tank average.
Until legitimate testing is done this product is about as useful as a whistle tip
Bill - I think I have worked out something, not quite what you propose, but something transparent, reliable and fun. Obviously, everything is up to the moderators, so, let me get someone into the loop, or if one or more of the moderators wants to contact me directly, by pm or publicly, I'll go over with them before posting.Yes, the idea was for trusted and knowledgeable members to do the testing. The Mods could choose the testers and only the mods would need to know who they are. The testers should not be new members, nor anyone thought to be either 'gullible' OR 'biased'.
The Mods would collect and tabulate the data, then publish the results, scrubbed of identifying information.
After testing the devices could be required to be passed on the next set of testers if you desire.
All this is just a suggestion, I am recusing myself of any direct involvement.
(Other than to comment loudly and often.)
You guys can work out the actual details at your leisure.

Its a good paper. Its been a few years since I read it, but GasPods are not vortex generators. They are patently distinct. This was addressed in an earlier post that I'm quoting below:Joining this conversation late - but here goes...
I had contacted Aeropod a while back and offered to be one of their "testers." I had at that point 250K miles of tracked (mpg, other) miles. Same as others have reported - 10% discount for being a tester, yada, yada, yada.
Since that time, I did some more research and the original paper published by the Mitsubishi team who placed the vortex on the Lancer is located here: http://geetaebook.com/pdf/aeronauti...namic.Drag.Reduction.by.Vortex.Generators.pdf
From a fluid dynamics standpoint, the vortex generators add more energy to the air/flow. That allows the flow the "hold on" to the profile of the car longer, creating a smaller negative air pressure pocket behind the car. The Mitsubishi vortex generators were both rounded and pointy. Neither "smooth" the air...
Just adding some light technical reading on the topic.
The problem with these studies, and our CFD is the same, they are specific to the questions asked, and the size, shape and configuration of the vortex generator or GasPod tested.....What you describe, creating micro vortices - just enough disruption - to do good describes vortex generators. GasPods are patently distinct from vortex generators.
GasPods function as you quoted and I explained in simple terms:
The surface area of GasPods is about twice their footprint. And, their shape is such that they bring more air into the streamline flow, air that would otherwise break away into turbulence and create drag, then accelerate it with the streamline direction, to drop a little more air into the low pressure behind. That reduces the drag by well, on the VW Golf, by 5.2-6.7%.
I think equivocating GasPods with vortex generators is the root of some of the confusion and criticism......
Thanks for posting the link! I think it had been posted before somewhere, but it's good to remind people.Since that time, I did some more research and the original paper published by the Mitsubishi team who placed the vortex on the Lancer is located here: http://geetaebook.com/pdf/aeronauti...namic.Drag.Reduction.by.Vortex.Generators.pdf
Thank goodness, at least one other person who gets it! I was already starting to lose faith in mankind here; especially after Susanne's 'explanations' (again, I don't mean to be condescending, but some of those posts must have been put together a bit too fast).From a fluid dynamics standpoint, the vortex generators add more energy to the air/flow. That allows the flow the "hold on" to the profile of the car longer, creating a smaller negative air pressure pocket behind the car. The Mitsubishi vortex generators were both rounded and pointy.
