A Nitrous Oxide System is a system used in racing to increase a car's performance for a short period of time. It involves the injection of Nitrous Oxide (N2O) into a vehicle's engine in-order to increase its power via a chemical compound for a short period of time. This will give the vehicle an increase in acceleration force for a short amount of time.
Players can upgrade a vehicle's nitrous kit with most titles in the Need for Speed series featuring three levels of nitrous injection; dry kits, wet kits and direct port kits. In Hot Import Nights, the fourth and final nitrous upgrades are nitro methane mixed direct port kits and Enhanced Nitrous Capacity, which of these are not only greatly slows the nitrous usage down before completely depleted, but also boost the chosen car even more faster.
A nitrous oxide system can be bought for a player's car from a Tuning Shop in some Need for Speed titles. It is available already equipped to vehicles in some other Need for Speed titles such as Need for Speed: Hot Pursuit (2010).
Variants[]
In Need For Speed: Hot Import Nights, every crew faction had unique variants of nitrous oxide.
- Every Bushidoshi cars use the standard Nitrous Oxide with no additional enhancements, but it can be usable during drifting in corners without loosing traction, but risky to execute. Even with the Nitro Methane Mixed and Enhanced Nitrous Capacity installed, the effect remains the same.
- Every 21st Street cars use the "Burnout 3" style Nitrous Oxide for extreme velocity power, but shorter lasting duration, and is thus capable not only overtake opponent cars, but also performs a takedown against the opponent cars without the main character driven upon hit while during the duration of Nitrous boost. Even with the Nitro Methane Mixed and Enhanced Nitrous Capacity installed, still short duration, but even more powerful and almost difficult to turning corners during Nitrous boost unless using the Speedbreaker.
- Every TFK cars use the "Enhanced" Nitrous Oxide for balanced velocity power and duration, and is thus capable of not only overtake opponent cars on hit, but twice longer than standard NOS. Even with the Nitro Methane Mixed and Enhanced Nitrous Capacity installed, the chosen car is even more powerful and longer lasting duration, but almost difficult to turning corners during Nitrous boost unless using the Speedbreaker.
- Every Mezzanotte cars use the "Asphalt 9" style Nitrous Oxide, with less velocity power, but longer lasting duration, and is thus can perform a Nitro Shockwave which not only overtake opponent cars, but also performs a takedown against the opponent cars upon hit while during the duration of Nitrous boost. Even with the Nitro Methane Mixed and Enhanced Nitrous Capacity installed, still weak velocity, but not only the chosen car's nitrous duration longer, but also massively slows the nitrous usage down before completely depleted, thus the player can nitrous spam as many as they want. But the tight corners need the Speedbreaker to slow down and take a turn.
