The prototype Legend aircraft (N-620L) was first powered with a GM V8 making 575/hp turning a 3/blade Hartzell Prop which first flew in 1996. With a surplus of Czech turboprop engines becoming available in 1997, the Legend aircraft was later converted to turbine power by installing the Walter M601 and Avia V503 prop which first flew as the Turbine Legend in 1999. Since that time, all Legends that have taken to the skies have been turbine powered.
Staying true to the original design, we are currently building a Legend with a GM LSA supercharged V8 engine and custom Whirl-Wind composite prop. The LSA is the highest performance crate engine ever offered by GM Performance Parts, producing 556/hp and 551/ft lb of torque. When ported and tuned by SAM Tech, the new Link ECU will control the direct port injection of each cylinder to optimize power and increase the HP to 750-800/hp, while keeping engine rpm restricted to 4500 for take off and 3500 continuous. Cruise RPM is expected to be 3200-3400 burning 18/gph while producing 300/kts TAS.
Stay tuned for exciting developments as the Piston Legend returns to the air.
