LoPresti Speed Merchants expects to receive an STC for installation of a DeltaHawk diesel engine in the Cirrus SR20 early next year. The modification will include a new LoPresti-designed cowl system, new Hartzell propeller and fuel system adapted to jet-A and biodiesel-type fuels.

DeltaHawk is expecting FAA Part 33 certification of the turbo-supercharged 180-hp DH-180A4 engine by the end of this year or early next year. “We’re working on a number of STCs on a number of aircraft,” said CEO Dennis Webb.
