He already started it about 10 years ago, when the naturally-aspirated 960 ci (15.7-liters) 12-rotor unit could easily churn out 1,400 hp. Working with Rob Dahm meant two things. A world of rotary ...

It’s a truly bizarre bit of home-grown engineering that was apparently made by a person from scratch using ‘40s milling equipment and some CNC machines in 2008. The three four-rotor engines ...

This engine produces about 690 horsepower in race-trim, a power figure it achieves from just 2.6L (654cc per rotor) of naturally aspirated engine. That is a truly astounding power/weight ratio.

While Rob Dahm’s garage is no stranger to monstrous rotary engines, including four-rotor units cranking out more than 1,000 horsepower, this one is mind-bending.Here we have a massive, triple ...

Mazda is known for its innovations in mass-produced rotary engines in sports cars like the RX-7, but it wasn't exactly the first to utilize Wankel's design.

The ram-rotor detonation engine, abbreviated as RRDE, mainly consists of a rotating rotor with blades, and a stationary casing. The blades on the rotor are distributed in a helical symmetric manner.
