See the “Little Dominator” engine for Noel Jensen’s basic design specifications. To achieve more power, in 1993 Jensen added two more cylinders and produced the flat 4-cylinder opposed model he dubbed the “Dominator.” It sports ringed pistons, bronze-bushed rods, ball bearing crankshaft and stainless-steel cylindrical rotors for valves. Its one-inch bore and stroke will spin a 20/8 propeller at 6,000 revolutions per minute. The engine is 9″-long, 8″-wide, and 9″-high.
