That video has been posted here about four times. The phrase "There's no substitute for cubic dollars" comes to mind. How many stovebolters can actually afford to build something like that, and for those who can, the burning question would be "WHY"?????? It seems it would make more sense to build in a moderate amount of power gain using off the shelf parts that a back yard tinkerer can afford, especially if those parts happen to come from engines made in the past 30-something years. Yes, it can be done.
