Gas mileage of single rotor engine.
 

What kind of Mpg would you see in a properly tuned and installed single rotor renny equivalent using conservative driving put into a car weighing around 2,200 pounds?

Would it be better, worse, or same as the stock Rx-8 engine?

The same mileage as a pig with wings would get.

Think about it this way:

The RX-8 uses about 40g/s of airflow to maintain a steady 70mph on a flat and level surface.

Airflow has a direct correlation to horsepower.

How would going to 1 rotor reduce the aerodynamic drag on the body of the car to enable it to use less power to maintain the same speed?


Smaller engines typically get better mileage than larger engines because of pumping efficiency. So yes, in theory, if you balanced out a single rotor engine, there would be very slight gains because the throttle would be open wider at the same speed.

There are still all the other efficiency problems with the Renesis's design that will have to be solved, and you still need the same amount of power to pull the car at a given speed, and you won't have a smaller engine because the balancing would be about the same size as the 2nd rotor. So you would end up with maybe 1-2mpg gain, over 50% power and torque loss.

Thx. I was just curious. Most of all.
