Installing the Gadgetman Groove for Improved HP And Mileage

Ron Hatton (“Gadgetman”) says he has come up with a simple way to significantly improve the mileage 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.

On Dec. 2, 2009, I had one of Ron’s dealers in Salt Lake City, Dave Richardson, added a couple of grooves to the throttle body in 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.

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.
