Ron Hatton ("Gadgetman") says he has come up with a simple way to significantly improve the combustion in normally-aspirated gasoline engines. All he does is use a Dremel tool to cut a groove of specific dimensions, around 1/8 inch deep, in the throttle body. The modification takes about an hour and is reversible through epoxy. It shouldn't affect the vehicle's warranty.
Somehow, the air turbulence that is set up by that groove has the effect of increasing horsepower, torque, and mileage, while decreasing emissions. Perhaps it is another manifestation of the famous

The mileage increase is typically between 25 and 35 percent, though some reports are much higher than that and a few show little, if any change. So far, it seems that older cars achieve better improvement than newer cars, because the computerized controls of the newer cars usually tend to work against the effect. Ron said that approximately 85% of the vehicles that have been modified with this groove have had mileage gains in excess of 20%. So far, the best results apparently have been found on 1996 - 2004 Fords.
Ron says he has filed for patents on the design as well as on the bits and that he is training dealers/installers from all over the globe to make this modification. He himself has modified around 200 engines.
On Dec. 2, 2009, I had one of Ron's dealers in Salt Lake City, Dave Richardson, do the modification on my Dodge Caravan, 2005 3.3L, V6. It took him about 55 minutes. I noticed a definite kick in acceleration when first starting out, though that could be a function of the more immediate air volume coming in due to the grooves.
Dave showed me his before and after dynamometer test results from the modification he made on his own truck. It shows a 15 horsepower increase and 8 foot-pounds of torque increase across the board.
On Dec. 5, 2009, I finished the first full tank of gas since the installation, and calculated that my mileage for that 392-mile stretch, using 16.6 gallons, came to 23.6 mpg. During that time, most of our travel was highway, but some (approximately 15%) was city driving. According to FuelEconomy.gov, my vehicle typically gets 16 mpg city, and 23 mpg highway. (With my recent move, I've misplaced the baseline data I accumulated last summer.) So our improvement in comparison to the average rating, was roughly in the region of 10% -- nothing to brag about, but still significant and worth while.
On Dec. 10, I finished my second full tank, travelling 359 mile (@119897 miles) on 16.883 gal, for 21.26 mpg, which is lower than the 23 mpg rating according to the govt. site but mileage is typically lower in cold temperatures and it's been very cold here during the relevant time (staying below freezing most of the time).
Dec. 23 @119266 miles 369 miles on 16.592 gal = 22.2 mpg.
Dec. 25 @119620 miles 354 miles on 14.153 gal = 25.0 mpg. (probably early shut-off error)
One thing that concerns me about the modification is that I don't have much wiggle room when I first accelerating. Most people would be delighted with the punch you get when you press the pedal. However, I'm concerned that if I'm on slick roads and I need to accelerate gingerly, that I won't have nearly as much control of speed-up, making it easier to spin-out. So for me, that is not a year-round benefit.
For me, I attribute that early punch in power to the fact that a little movement of the throttle early on is opening it to a large opening due to the groove, where before the opening of the throttle flow was much more gradual. So I don't attribute it to "more horsepower" but to "more airflow". I'd have to take the car to a dyno with before/after to document horsepower.
One thing that is admirable about the Gadgetman site is that it publishes all mileage reports, including the mediocre ones, as well as a few that actually saw their mileage get worse.
At this early phase, they are still anxious to increase their database and they are still making decisions about how much to charge for the modification so you are likely to be able to get a good deal on your install. Dave did mine for free. He personally wants to accumulate more data before going all out on this venture.
The installations come with a satisfaction guarantee.
FROM RON HATTON, GADGETMAN Feb 28, 2011
After much prompting, I have recorded a video that explains the science employed to generate the continued reports of increased performance. The video appears here:
I have now modified almost 700 engines, and have learned the removal of the PCV valve to be a critical part of the application of The Gadgetman Groove. What happens is the PCV valve represents as a direct vacuum leak, reducing the pressure wave the groove creates. The crankcase remains vented, although only with passive vacuum rather than full dynamic vacuum. This enhances the results in every case.

On Tuesday, Dec. 8, 2009 at 10 am, Ron Hatton will be holding a dynomometer-tested pre- and post-modification on a 2004 F-150. It will be held in Chandler at AZ Dyno Chip, who has an excellent reputation in the area for quality work. Their address and a map can be found at http://www.arizonadynochip.com/directions.php

After the groove is made, the throttle is still essentially air tight when closed. Here some acetone that was used to clean the throttle body, is sitting in the enclosure, slowly dripping.
The following include some selections from that channel.
In this video, I show the principles behind The Gadgetman Groove and why it does what it does.
Here is Mike Childs of Mesa AZ reporting on the results to his Dodge Ram.
Here we have 40-Year veteran mechanic Ron Fielder report his findings on his 04 Titan and his 06 Mustang GT. Also mentioned is the performance on his race truck for B-D Racing.
On Nov. 30, 2010, Congress:Founder:Sterling D. Allan asked Ron Hatton: "Have you tested to see how the Gadgetman Groove effect HHO systems? Improve? Additive? Redundant?
[11:45:38 AM] Ron Hatton: It will further enhance the fuel-hydrogen-oxygen mix. In a 2000 Land Rover Discovery, it got 35% on 2 LPM HHO. When the groove was added, it increases to a 50% gain.
: "[Here] is the dyno chart for my 2007 Toyota Tundra. The chart represents the "before and after" measurements of horsepower and torque. After the Gadgetman Groove was applied, horsepower increased 14.94 and with torque showing a gain of 8.42 ft lbs." -- Dave Richardson
The price point for this modification by professionals is $350. Ron encourages all "G-men" to charge $100 when they first start out, then $250 as the demand increases and their skill level improves, then $350. I thought that was too high, for a task that takes 1 hour, but Ron pointed out a few things.
# At that price, the typical driver is going to see a return on investment in between 6-12 months due to the usual mileage improvements seen.
# The install lasts the duration of the vehicle.
# At first, he was charging $100, but the lower price gives a low value impression. His sales went up and referrals increased when he bumped his price to $250.
# The pros say that each added horse added to the engine's HP is worth $100 each. The average HP gain is in the region of 15.
# $350 is so the shops that are signing on have a base. The shops Ron has approached have been excited about the price point, and have told him they believe it to be fair.
# There are start-up licensing and tooling costs for installers to be recouped.
Older, carbureted engines are usually more involved and will thus cost more to modify.
ADDENDUM BY GADGETMAN
The pricing is established based on the number and style of ports through which the air passes. The overwhelming majority are single, rounded port systems. For these, the modification price is $350, including single barrel carbs. For dual and oval ports MPFI systems, as well as 2 and 4 barrel carburetors, the cost is $500.
Most carburetors accept the modification with great ease. Best results to date (Feb, 2011) have been found in the Edelbrocks and Holley's, with rejetting advised to maximize fuel efficiency.
Only certain older carbs are virtually impossible to modify. In particular, Quadrajets present the greatest difficulty. This is due to the way the throttle assembly was engineered, leaving too little room to install The Gadgetman Groove.
Additionally, vehicles NOT suited for this modification are:
1) 2007 and later Excalades-Computer acceptance issues
2) 454 TBI (Throttle Body Injected) General Motors-idle air passage interference
3) Certain (as yet undefined) 2004 and later GM products-a whistle is generated, making some drivers uncomfortable.
4) All engines with "Constant Velocity" throttles.

Ron has been involved in fuel efficiency for about 25 years. More recently, he has been involved in Directory:Hydroxy or HHO Injection Systems research, but with the groove discovery, he has been focusing his attention on that. As far as he's been able to tell, the two processes are not supplemental, though Dave Richardson seems to think that some results point to a possible synergism.
So far, Ron has spent around $400,000 in this quest.
Ironically, Ron can't drive, as he is 95% blind but that doesn't seem to impair his ability to work on engines. Dave Richardson mentioned that one would hardly tell he has a visual impairment when he's under the hood, going about his work with speed and skill.
