A serious add-more-power option for your motorcycle is nitrous oxide 'Juice' and 'squeeze' are typically associated with nitrous. A nitrous oxide system (NOS) is not mechanically driven and does not pressurize the engine's induction system (intake port, manifold, carburetor or EFI throttle body), as do superchargers and turbochargers. Essentially, nitrous oxide is power in a bottle. In other words, it is a chemical-based supercharger that increases pressure in the engine's combustion chamber.
From a chemical standpoint, nitrous oxide is a non-toxic non-flammable clear-gas oxidizer, which is stored in a liquid state under pressure in a bottle. Releasing nitrous from a bottle instantly changes it into an oxygen-bearing gas. The oxygen-bearing gas can increase the percentage of oxygen in the cylinder to roughly 50 percent, which is more than double that of a naturally aspirated engine. More oxygen in the cylinder allows more fuel to be added. Increasing the air (oxygen) and fuel in the correct proportion produces greater combustion heat and pressure on the pistons, resulting in higher power production. With the push of a button, a nitrous system injects nitrous oxide into the engine's intake tract along with air and the appropriate amount of fuel to ensure proper combustion. As combustion takes place, the chemical bond between nitrogen and oxygen is broken and the oxygen becomes usable for combustion. The increased amount of oxygen in the cylinder allows fuel to be added, resulting in higher combustion heat and greater power production. In simple terms, whenever the rider decides to push the nitrous button, he can have increased cylinder pressure and greater power.
One major difference between nitrous oxide and blowers/turbos is that blowers and turbos pressurize the intake tract 100 percent of the time. In contrast, a nitrous system s active only when the rider pushes the button; otherwise, the engine operates as normally aspirated. Although a NOS can be activated at any rpm to minimize potential engine-damaging detonation. For a street engine, that means about 4,000rpm and up. On the other hand, a nitrous system is normally activated at a lower rpm on a modified race engine run on high-octane fuel.
