Our three rotor engine produces similar horsepower to a Lycoming IO-540. But it weighs over 100 pounds less and costs over $20,000 less. It has all of the modern engine features that the 50 year old Lycoming design does not, such as water cooling, fuel injection under computer control, turbocharging without the need for an intercooler, and space-age coatings inside the housing for much longer engine life.
It takes six pistons, and hundreds of pounds more weight to get this kind of horsepower from the competition. The Continental GTSIO-520-H produces horsepower in this range. But it costs nearly $20,000 more. This engine is water cooled with thermostatic temperature control, fuel injected, and turbocharged for the same output at all altitudes up to 18,000 feet.
