Enhanced Aircraft Systems (EAS) has introduced the O-408 and IO-408 engines, which incorporate the use of technology from Formula One auto racing to develop advanced components, such as crankshafts, connecting rods, pistons, and piston pins. These parts can be retrofitted to any existing Lycoming, ECi, or Superior Air Parts 360 CI engine, or can be incorporated into a new engine, company officials said.
The main goal of the design was to move weight from the reciprocal parts (connecting rods, pistons and piston pins) to the rotating part (crankshaft), reducing stresses and vibrations, according to company officials, noting that the 408 engine, while producing 230 hp, generates lower vibrations than an O-320 at a similar power setting.
San Antonio-based Enhanced Aircraft Systems specializes in improvement products for legacy aircraft, including many STCs and PMAs.
