total BS. anyone with even a basic understanding of efi will understand that a groove under the throttle plate will do nothing to the idle (compensated for immediately by the idle air solenoid) and will have zero effect on mixture (immediately compensated for by the ecm). no effect on atomization either, as it's too far upstream to even see fuel. Looks to me like some here may have a vested interest in this scam. most likely make millions from the deal if prior similar scams are any indication.

Well I have quoted many sites on my post which stay this works well after the throttle plate. Feel free to read them and you could go to the www.gadgetmangroove.com web site and see for yourself. I'm just posting the facts on TBI and doing my own independent test to see if it work.

I'm working on testing but it cost money to run tanks of gas through ones truck. As of today I'm still working on my stock fuel numbers for city and freeway. I have not bolt up the modded TBI yet. You could go look on the gadgetman site to see what other are doing. I'm posting this test there too. My first tank of gas for my stock numbers was 12mpg on the 350 auto 1ton with a 4:10 gear city/freeway.

Been around a lot long that you! And this is not my first product test I have done here! If I was a spammer I would be telling everyone how great this product is. I Ask the question. So if you have any info or web site disproving this Idea I would sure like to see it to add to this information.

The earth is flat, and water does run off the edges. the water recirculates and comes up under the ocean to replenish the supply. in a very few places this recirculation actually happens on dry land as well. proof of this can be seen in places like Yellowstone park where the earths crust is thin and the water breaks through from time to time, forming what we call geysers. The unfortunate thing is that in less than 8 months the alignment of the stars will be such that the earths axis will tilt and so much volume of water will run off one side of the earth that it won't be able to recirculate and our wonderful planet will dry up and die. It is interesting that you mention this now however, as, fortunately for you, I've recently invented a magnetic shift induction coil that will 100% guarantee this event will not take place if purchased from me, and installed under your bed before December 21st 2012. my coils work by capturing the power of the aura borealis. which is, as you know, caused by powerful eruptions on the sun. by harnessing the power of the sun in this way, via my patented shift induction coils, the magnetic fields of the aligned planets will be counteracted and the earth will be totally unaffected by this otherwise devastating event. I offer a double your money back guarantee just so you will know how confident I am in my device to keep this event from ever happening.


Thanks for your time.

ChevyTruckGuy. I mean no disrespect by my doubting this "groove" will actually work. I think it's great that you're interested enough to test it out for yourself.

Over the years, manufacturers have added grooves, vanes, and bumps in intake manifolds and cylinder heads to fight fuel separation issues associated with fuel being atomized so far from the cylinder itself.

It would be interesting to see what was happening to the air and fuel, while the motor was running, with the throttle blades nearly closed. A high speed camera mounted in the intake maybe?

If there was any separation at all........A grove such as the one being talked about........ "Could" in fact make a difference.......

On the flip side..........You could screw up the manufacturers efforts, and actually cause a fuel separation issue.......Dan

IF one were using a throttle body FI system, then perhaps (not likely). but the gadgetman is showing it on a port injection system throttle body. in the port injection system there is NO FUEL anywhere near the groove to atomize. atomization doesn't begin until fuel is injected right at the head ports.

If you read the circle track posts it states on the newer cars you would see little improvement if any at all depending on the design. I'm doing the TBI as it seems to work the best from my research, Oh and carb's. The claims are low end Torque better fuel mileage reduced engine temps and emissions! I'm following the forum you can see the pros and cons more insight that I can give everyone Here.

So ,did you ever go through a few tanks to find out if this scam works or not?

[cobalt327]

For the small amount of expected improvement from this groove, careful testing has to be done or the results are basically meaningless.

One of the many problems w/testing schemes like this is to do it scientifically. One concept of the scientific method is only ONE change can be made at a time. And you need a control- in this case it would be an identical unit w/o mods to test back-to-back w/no other changes.

To test on different days, possibly months apart, will not give a conclusive result unless the results are overwhelming. In other words, the changes could be so small that just different weather or ambient conditions will mask them unless the change is very large.

I would compare this to Singh grooves. There's just enough buzz to make you wonder, but when it comes right down to hard, repeatable results showing a measurable improvement, they're lacking for the most part. I believe the best thing that can be said for this is it will probably not hurt anything.
