Recent research centers on the positioning of cooling channels in injection molding tools, the design of pre-forming geometries for forging processes, and autonomously controlled automated guided vehicles ( AGV ).

In addition the thin inner liner requires mechanical support to withstand the compressive loading due to the propellant's pressure; this support is usually provided by the side walls of the cooling channels and the backing plate.

It s a very complex engine, and it was very difficult to form all the cooling channels, the injector head, and the throttling mechanism . . . . [ The ability ] " to print very high strength advanced alloys . . . was crucial to being able to create the SuperDraco engine ."

This engine was manufactured with a reinforced cylinder block and cylinder head, metal head gasket, pistons with cooling channels, forged crank shaft, forged connecting rods, N1 turbine with reinforced actuator, high flow air cleaner, stainless down pipe, and low air resistance sport catalyzer, most of which were not offered for the RB26DETT . RB-X GT2 engines competed in LeMans 24hr race, Pikes Peak, and other forms of motorsports.
