Camming a race engine for use with nitrous also requires a bit of thought. If your customer plans to use "the bottle" only after the car has been launched (possibly in high gear only) a cam must be selected with that in mind. A car won’t produce very impressive elapsed times if it’s a slug until the nitrous system is activated.

All other considerations pertaining to building engines for use with nitrous oxide, come under the umbrella of common sense. Given that power output jumps from 50 to "who-knows-how-much" horsepower when a nitrous system is activated, component strength is of prime importance.

Standard pistons won’t cut it, at least not for very long. Hypereutectic or forged pistons are required to assure acceptable durability, as are race-prepared style connecting rods and a well-prepared crankshaft.

The oiling system also warrants attention in the form of blueprinting the pump, accurately setting bearing clearances, enlarging drainback holes and fitting a well-baffled oil pan. Basically, nitrous oxide is a chemical supercharger, so an engine must be built to handle the "boost".
