What is the sound of one piston slapping?

Illustration for article titled Rotary noize: Rod Millens 20b 4WD fc RX-7 turbo.

I can only imagine the logistical nightmares doing dyno runs with nearly external combustion engines. In the video below, it was carbureted and 300hp. It did run Pikes Peak with a turbo and the whole passenger side of the car replaced with metal heat shielding (seen in the picture).

Lately, it was recently rebuilt over at Rotorsport Racing in NZ. Here it is on boost, as in that picture, bumping out 610hp.

So one can hope that they bring this out and into the public, they being whoever this job was accomplished for, and let it eat once in a while at a publicized festival somewhere so we can all experience the sounds and feels and sights of it sliding it’s way anywhere it want’s to.
