Never before seen footage of Defined Autoworks assembly of its in-house 4-rotor race engine, D26R. First 4-rotor since the 787b to use triple spark plugs per housing and telescoping intake manifold. All custom built at defined autoworks. The worlds first ever 4-rotor to use a 5th main bearing, in the center. This along with other internal modifications allow for 12,000 rpm capacity.
