How To Build A Rotary Engine
Joe Ferguson from Mantella Autosport assembles a Mazda Renesis 13B rotary engine using Goopy Performance seals and refurbished housings along with Racing Beat ported irons and lightened rotors. Dave and Joe take you on a serious rotary geekfest as they show you exactly how these engines go together and explain how the unique Wankel combustion process works as well as covering some of the strengths and weaknesses of the Renesis vs older versions of the 13B. If you're ever at a Pirelli World Challenge race, go say hi to the guys at Mantella Autosport, tell them we sent you, and get a good look at their amazing KTM Xbow GT4 racecars.

4 Reasons Why The Rotary Engine Is Dead
4 Reasons Why The Rotary Engine Is Dead. The Wankel engine was last seen in a production car in the Mazda RX-8, and currently there are no rotary engines in production. Mazda may bring it back in the RX Vision, however there are many disadvantages to the rotary engine which has kept it from being successful. Rotary engines have a low thermal efficiency as a result of a long combustion chamber and unburnt fuel making it to the Exhaust. They also have problems with rotor sealing as a result of uneven temperatures in the combustion chamber since combustion only occurs in one portion of the engine. Oil consumption is also a problem, as oil is injected to add lubrication and help keep the rotor sealed. Finally, emissions are poor and fuel economy is terrible, and ultimately this is the cause of it’s death.
