technical what is nitrous oxide technical information ent from setting a glass of water outside and waiting for it to dry up in the engine of course evaporation happens very quickly engine heat and fuel atomization are the keys to accelerating the evaporation process enough to turn raw gasoline into a vapor at 8000 rpm the process of atomization turns raw fuel flow into tiny droplets which then evaporate faster due to the larger amount of surface area presented for evaporation the size of the fuel droplets is very important take a large droplet of gasoline break it up into 10 smaller droplets and you ve increased the surface area for more efficient evaporation the result is more fuel available to be burned and do work during combustion a welldesigned nitrous system will produce very small droplet sizes in the supplemental fuel that flows into the engine with nitrous this is one of the reasons that nos nitrous systems can make more horsepower than some other systems the third basic power factor we will look at is air/fuel mixture density ever try to jog on top of a 10,000 foot pass in the rockies leaves you gasping for breath doesn t it that s because the air is thinner less dense higher up in the atmosphere than it is at sea level it is also why you would run slower on a track in denver than you would near sea level in new jersey density is affected by atmospheric pressure the weight of the atmosphere above you heat and humidity we can t change the pressure of the atmosphere but we can regulate the heat of our intake charge to some extent cool cans and intercoolers make extra power by cooling the fuel and air/fuel mixture to make it denser and the denser the mixture is the more the cylinder is packed with fuel and air to burn and make power when nitrous oxide is injected it turns from a liquid to a gas instantly and becomes very cold this cold nitrous vapor drops the temperature of the whole intake charge in the manifold by as much as 65 degrees f the denser mixture that results helps an engine produce even more extra horsepower with a nitrous system what nitrous oxide is and what nitrous oxide isn t to your engine nitrous oxide is a more convenient form of normal air since we are only interested in the oxygen the air contains nitrous oxide provides a simple tool for manipulating how much oxygen will be present when you add additional fuel in an attempt to release more power the power always comes from the fuel source nitrous oxide is not a fuel nitrous oxide is a convenient way to add the additional oxygen required to burn more fuel if you add only nitrous oxide and do not add additional fuel you would just speed up the rate at which your engine is burning the fuel that it normally uses this more often than not leads to destructive detonation the energy comes from the fuel not the nitrous nitrous oxide simply allows you to burn a greater quantity of fuel in the same time period thus the overall effect is a tremendous increase in the total amount of energy or power released from the fuel and available for accelerating your vehicle there is no voodoo involved in nitrous oxide in effect using nitrous is no different from using a bigger carburetor a better manifold a supercharger or a turbocharger understand that the air you and your engine breathe is made up at sea level of 78 nitrogen 21 oxygen and just 1 other gases nitrous oxide n2o is made by simply taking the 2 major components of earth s atmosphere in this case 2 molecules of nitrogen and 1 molecule of oxygen and attaching them together with a chemical bond when the nitrous oxide goes into your engine the heat of combustion breaks the chemical bond to provide your engine more oxygen with which to burn fuel as you ve read all race engines operate under the same principles more air better breathing supercharging turbocharging or nitrous plus more fuel in a denser vapor equals more power nitrous oxide vs other performance products dollar for dollar nitrous oxide offers the most performance a consumer can buy you could spend thousands of dollars on carburetion a manifold valve train components exhaust pistons porting supercharging or turbocharging to get the same amount of extra horsepower that a nitrous system would provide for just a few hundred dollars but this doesn t mean you won t benefit if you also install other performance parts once you have installed a nitrous system all those other performance parts just increase the nitrous power if you just have a few dollars and want lots of extra power the best choice is an nos nitrous system only nitrous is a part time power increaser all of the standard performance parts put additional stress on the engine and burn more fuel all the time not to mention what a pain it is to ride around town with a lumpy idle from a camshaft that is barely streetable power on demand is one of the great things about a nitrous system it only works when the driver wants it all the rest of the time the engine operates normally no extra stress no extra fuel use and no driveline problems what you get when you buy a nitrous oxide system from nos of all the components in your nos system that you see when you take it out of the box there are three things that you may not fully recognize until you have gone through the installation process and used your nos system for the first time integrity we stand behind our products if we claim a system is capable of 100 horsepower it s because we designed it that way tested it that way and manufactured it that way if you are willing to follow our guidelines you ll get the results that we say you ll get quality there are a lot of things we do everyday here at nos we test our products and systems on sophisticated measuring equipment as well as the real-world environment of the vehicle it s intended for we pay strict attention to the manufacturing procedures required to maintain our high standards for components we listen to what you have to say about the performance of our products along with your suggestions for new applications our tech staff relays your comments to efi wet dry systems nitrous system theory selection and tuning as modern engines become more difficult to modify the use of nitrous oxide to obtain phenomenal performance gains is on the rise and for good reason we firmly believe that our nitrous systems and related products are the highest quality performance and value available anywhere in the world we can make this claim because we ve been manufacturing nitrous systems and components since 1978 the value of this to you is the vast experience we have accumulated throughout the history of our company among the many true bolt-on performance enhancing products available there are few that can even come close to comparing to the dramatic results of a power increase provided by one of our nitrous systems in both the simplicity and reliability that you get when you install a nitrous system that carries our world-famous nos logo you ll be amazed at how easy it is to produce the one thing everyone is always searching for more of power when you consider all of the options you have to get an engine to release all of the potential power it can there is no equal to the ability nitrous oxide provides you if you look at a nitrous oxide system on a dollar-perhorsepower basis you ll find that a nitrous system from nos can provide the greatest value for each dollar of your precious investments our experience throughout the years has proven to us that performance enthusiasts and racers alike are most impressed by the ability to add 10 to 200 horsepower within a period of just a few hours by carefully choosing the correct system for your applications you ll be assured of a performance increase and reliability factor that could only be compared to doubling the size of your engine by simply activating your nos nitrous system how to make horsepower an engine operates by burning fuel which then expands and pushes the pistons down want to make more horsepower burn more fuel so it will push the pistons down with more force sounds pretty simple but it s not quite so easy while there are any number of factors that make increasing power a complex engineering problem we will deal with three of the most basic ones here first all fuels require oxygen in order to burn if you want to burn more fuel you need to also put in more oxygen virtually all engine performance products increase power by increasing the flow of fuel and oxygen camshafts larger carburetors or valves porting intake manifolds exhaust headers superchargers turbochargers and nitrous oxide are clear examples of how improved engine breathing putting in more oxygen in order to burn more fuel will give you an increase in horsepower nitrous oxide injection systems are probably the most efficient way to increase the flow of oxygen and fuel that s the basic reason why nitrous systems produce such large horsepower increases another basic power factor is vaporization of the fuel gasoline as with other racing fuels will not burn in a liquid state the gasoline must be turned into a vapor for it to burn this process of turning gasoline into a vapor is simple evaporation it is basically no differ part index tools merchandising fuel pumps regulators gauges
