Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together. There was a lot of trial and error as jury-rigged parts were improvised and revised, leaks were identified and plugged, and byzantine electrical diagrams were decoded. It still does not run smoothly, as there likely is a problem with the intake system that has prevented smooth timing at idle. But she runs! lots of people wanted to know where the E-shaft came from: it was custom ordered from a shop in New Zealand.

Mazda Rx7 4-rotor race car. The making of a Defined Autoworks Beast. [Offical Video]
Never before seen footage showing the assembly/start-up of our custom 4-rotor. It is the first 4-rotor since the 787b to use triple spark plugs per rotor. It is also the first since the 787 to feature telescoping intake manifold. Custom made slide throttle body system. A world first however is the use of a center main bearing and 4-piece eccentric shaft. Quick specs- 9.7:1 rotors, lightened and race clearanced. Race main bearings, and race rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full custom Peripheral Port in each rotor housing (defined auto), Aluminum side housings for reduced weight. Needle roller bearing in the center housing. 4- Piece eccentric shaft 0:47 Dynamic engine balancing 1:23 Variable length intake 2:20 Engine assembly 2:32 Rotor rotation 3:49 Slide throttle 4:00 4-rotor startup and idle 4:30 All footage and editing was done by Defined Autoworks.
