As you can see in the pictures above, we have before and after
shots of the same piston used in an engine that was subjected to multiple 300HP. nitrous oxide shots from a ZEX 4500 Dominator
plate system. The thermal barrier coating (gold colored coating) helped to reduce the amount of transfered heat through
the top of the piston. The advantage of this coating really comes into play on high heat, detonation prone applications
such as supercharging/turbocharging or nitrous oxide. By controlling the amount of heat on temperature sensitive components
like pistons, we are better able to tune the engine out farther on the ragged edge where more power exists.

Here on the after picture, we can clearly see that most of the
coating is still intact. This particular engine was run with a very tight quench area 0.0280" of an inch. Under
the extreme pressure in the combustion chamber with the nitrous oxide, we didn't see any evidence of detonation, or any
other abnormality associated with large amounts of nitrous oxide. Everything worked the way it should have worked.
What does this mean to you? By reducing damaging excessive heat propagation through the piston to the point where it
starts to melt the piston top, we save the piston, and we save the engine. More importantly we put you, the customer,
in the winners circle while the other guy stares at his melted, dead engine.
