Rotary engines are incredible, you hear a lot of people talking about how good the hp/l is. But the thing is the hp/l on most rotary engines is really not all that spectacular. Now here is why, take the high powered JDM RX7 that actually has about 280 horsepower. For a 1.3 litre engine that is 215 hp/l, on an engine that is hardly stressed. Rotary engines make this much power because they fire twice every combustion cycle, so it should be rated as a 2.6 litre engine, this makes 112.5hp/l, still a good rating, but really for an engine using forced induction this is not spectacular by any stretch of the imagination. I mean the Lancer's make 140hp/l with forced induction, and like the rotary engine is very unstressed. Now before you start flaming me for bashing the RX7, here is why rotary engines are great. Rotary engines have very few moving parts and are very small, 1.3 big engine, that displaces as much as 2.6, this is very good for weight. If you have ever seen the engine bay of an RX7 it is very umm empty. The engine is very small and is actually tucked behind the front axle very close to the middle of the car this technically makes the car a mid engine car. And it gives the car a great weight distribution. This is why the RX7 is such an autocross demon. And that my friends is why rotarys kick ass.
