Why doesn Jett publish the horsepower of its engines?
Jett reveals the power of its engines by publishing and guaranteeing the RPM each engine turns a specific propeller. This may be easily compared to similar data from the competition. HP figures are not so easily compared because there is no industry standard with which to test. As a result, each manufacturer tests independently of the other, often on uncalibrated equipment. In cases where competitive advertisements claim power on the optimistic side, Jett is forced to remain silent, or publish equally optimistic claims. Comparing RPM on a fixed and available brand of propeller is the only way to accurately compare engines. It is usually ok to compare HP numbers generated by the same person, i.e., a tech writer. Just don’t compare his numbers to someone else’s.
