Rocket-tabs

ABA testing with documented methodology or bust. There's no way they do 20%. Honestly, they probably INCREASE aerodynamic drag and hurt mpg if there's any effect at all.

It's real! I just installed a set today on Silver Aero and pulled 90 MPG over a 10 mile drive!

Actually, not. Silver Aero is sitting 700 miles away back home until I get back and sell it and get my Insight...which will be able to get 90 MPG!

Atleast that is the right attitude if you believe in your product. (Unlike the nano-tribo shizzle). If the respectable members of this forum see benefits, you will probably instantly get as many orders as active members.

I would volunteer for testing but my logs so far are not that precise and would provide no benefit to this thread.

There is now a YouTube video with testing on the web. It's a short video. Title is rocket-tabs.

What stands out to me is that you didn't control for engine temp and elevation changes. (Going one way for A and the other way for B is really bad)

There is a great post on how to test mods here:

Thank you for the comment. I read over the link. I like you had to many times with and without tape on the grill. And hear my wife say, now what are you doing. Enjoy

In order for the tabs to improve the vehicle's FE 20%, they would have to almost entirely negate the aero drag of the tires themselves.

I smell a rich, earthy aroma, like manure. Unicorn manure.

My thought was to send them some people and talk about results. Maybe why or how they.

Let's take stock of where are here. You have a product, Rocket Tabs, and you hypothesize that these tabs reduce the wheel drag of a car, and you (belatedly) posted a test confirming this. But I don't think you realize that there is significant reason to doubt your results.

The first is the order in which you did things. Scientists hypothesize all the time, then test those hypotheses, observe the results, identify possible sources of error, revise their experiments and test again. You had a hypothesis, then created a product and made a website offering them for sale, then posted a video of a test after people here expressed their disbelief. If you did not test these until that far into the process, what made you confident enough to create a website and offer them for sale? Now, any testing you do is immediately suspect because you aren't performing it in the pursuit of scientific truth, but to support your business model, with catastrophic results to your business if your testing shows anything other than a result you expected.

Second, you seem unaware of some important parts of the scientific process. I'm taking a college chemistry course right now, and the first week was spent entirely on the scientific process--observations, laws, hypotheses, experimentation, theories. An important part of the scientific process is analysis of results--identification of measurement errors, procedural inaccuracy, unaccounted-for variables. We have to do 14 labs in this chemistry course, and for every lab write-up we must compare results with the rest of the class, identify sources of error in our results or others', and identify ways to improve our experiments were we to run them again. In the real world, this is even more important! Since you are investigating a phenomenon (well, you would be simply investigating it if you didn't already have a vested interest in seeing your business succeed) out in the real world, hoping to profit off of it, your process had better be bulletproof. And I'm sorry to say, it isn't.

That process has some significant sources of error. I'll wrap up by asking you to consider these questions, to hopefully get you thinking about them: What variables could have skewed your results? How did you control for these variables? Do you think others could reproduce your results exactly? Why or why not?

If you're really interested in a discussion of these devices, let's start with the answers to those questions.

It is a business idea. It did not start out that way.
I was trying to 50 mpg from a 2001 prius. I did get that with many failed attempts.
So, I thought how can I make this happen?
I started checking wind tunnel results online for good and bad points.
I found top and bottom tests. No sides or very little.
I started looking into ideas. I drove past wind turbines everyday.. it dawned on be to try the first gen of tabs.
Maybe 20% however very ugly. I tried until I got to gen 6
The testing was done on a month to month basis driving the same 34 miles one way.
All the sizes have been tested and location on the wheel. The best and cheapest are what I have today. 2 years of test and changes some 40k miles.
I too hear 20% and say no way.
Weather is a very important part of data. Well you know.
I claim up to 20%. Sometime 10%.
I have seen city mpg increase, rpms drop. Cabin noise drops. I can now drive with the windows open.
To address can you get the results.
I am not able to test all cars and honestly hope you. Will they work on a 56 Chevy. No idea. I do know that they work on the cars I have tested.
The big issue I have is, if we all drove the same with no wind, then yes. I can tell you I have seen improvements overall.
Thank you for you comment.
