+1 for the Pure Sounds videos.
+1 for Love the Beast.
Howstuffworks.com has some great animations showing how internals work. It's my goto for showing people what actually goes on inside a rotary.
Of course, there's no substitute for standing next to the wall and having your chest reverberate as the C5-Rs come down the back straight... no choice but to have your heart beat in sync with the exhaust pulses... just to FEEL the sound that those things make in every inch of your being. It's a religious ecstatic moment.... even for a Ford guy like me.
