The idea is to reduce the size of droplets of fuel so that they will burn more easily, same idea as electronic fuel injection. On the one chart, they show that the motor made 13.6 more horsepower with the device installed, a cost of $2.94 per horsepower if you pay $40.00 for the device. With the current cost of horsepower being about $10.00 per horsepower, $2.94 seems like a pretty good bargain to me and I would be a player if I had a carbureted motor.
