" The problem is
that they have lots of emissions issues, have incredibly hot exhaust
gases, are very prone to damage by detonation, and typically have poor
low end torque."

RE: Rotaries
        Torque goes up as the rpm increases. At the 1978 Mazda RX7
introduction, the Japanese engineer, he later became president of the
company, who made the rotary work by utilizing sliding tips, answered my
question about torque by drawing a graph. Up the left side were numbers to
indicate rpm. Across the bottom was horsepower, left to right. Then he drew
a line upward at a 45 degree angle from Zero to indicate how the torque
increases. 
        At a Daytona 24 hr race several years ago, the Mazda factory entry
was recorded having 114 dbA on the sound scale.
