DISCLAIMER: Building, testing and operating a homebuilt engine can be extremely hazardous! Get professional advice, approval and training before attempting to construct or operate such an engine. The ideas and material put forth on this page are to be considered experimental and untested. This page is not affiliated with HCI INC., but serves those who have bought plans and are building their design or a derivative of it.
