" Ratings of Efficiency

There are many different ways to find the efficiency of an engine, and many different parts of an engine that you can rate the efficiency.

Thermal efficiency is the percentage of energy taken from the combustion which is actually converted to mechanical work. In a typical low compression engine, the thermal efficiency is only about 26%. In a highly modified engine, such as a race engine, the thermal efficiency is about 34%.

Mechanical efficiency is the percentage of energy that the engine puts out after subtracting mechanical losses such as friction, compared to what the engine would put out with no power loss. Most engines are about 94% mechanically efficient.

This means that for a stock engine, only 20% of the power in fuel combustion is effective."

Cyclone is looking good!
