The key to engine reliability when using nitrous oxide is to choose the proper horsepower increase for a given application. Kits using the correct factory calibrations do not usually increase wear. Increased cylinder pressures also increase loads on the supporting components. If load increases exceed the load capacity of the supporting components the result is increased wear. Nitrous oxide kits are designed for use on demand only at wide-open throttle. Making nitrous oxide extremely advantageous in that it is used only when needed, not at all times. Nitrous oxide kits are designed for maximum power with reliability for a given application.
