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.
The Mazda Rotary Engine Part 1
Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the
Rotary engine works with comparisons to the Piston Engine. Also shows the
Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or
110S). Originates from the late 60's.
Rotary Rotational Demonstration
A little video for all those folks that refuse to accept the "3:1"
principle of planetary motion inside the Mazda Rotary Engine.
EDIT: For you people that are hung up on my comment at the end of the
video, I suspect you are probably one of those at which the comment
It never ceases to amaze me how many people will see this video and
continue to argue that there is some other relationship other than 3:1
between the inside and outside worlds of this motor.

Sending RX7 To Rotary Hell (almost blowing up the garage)
Lasted 8 minutes and 8 seconds at full RPM with blown rotor. Skip to 7:10
for its demise. And skip to 8:05 for a REAL laugh, #finale ;) (2013)
...what's up with all the dislikes? Jeez, you guys wish we could've sold it
to you with a salvaged title? Or y'all just mad a Rotary lasted that
Destroying an old blown 13b motor(over 100k) before swapping in a 13bt. The
old motor just wasn't worth keeping so why not have a little bit of fun
with it before spitting it down to hell? Enjoy. (2007)
