 This also produces more exhaust gases so that the turbocharger quickly spools up, providing more oxygen for combustion, and the N2O flow is reduced accordingly.The expense of both the system itself and the consumable N2O can be significant.For more engine power, and to augment the benefits of forced induction (by means of turbocharging or supercharging), an aftermarket water injection system can be added to the induction system of both gasoline and diesel internal combustion engines.
