Imagine
the stressed life of a racing piston. Rotating at up to 20,000 rpm, combustion temperatures of up to
1500 degrees C on the
crown with the risk of being "pinged" to death by detonation
and all the while it must deliver the power for minutes or hours. Quite
a challenge to survive at the limit yet the application of performance
coatings brings about improvements.

After application of these three coatings, engine power increases of 5% are achieved through more ignition advance, a higher boost level or, on two strokes, by leaning off the air/fuel ratio.
