According to Matt Maxwell from ZEX, Nitrous Oxide, N2O, is a gas composed of two nitrogen atoms bonded to one oxygen atom. When nitrous is injected into the engine while initial combustion takes place, it creates enough heat to separate the nitrous oxide into its two components nitrogen and oxygen. Once separated, the extra oxygen is then free to react with the additional fuel. Maxwell added that burning more fuel creates higher cylinder pressure that pushes down the pistons with greater force (measured as Brake Mean Effective Pressure or BMEP) thus producing more torque (horsepower being a calculation based on torque and engine speed).Maxwell: A “shot” is typically how much horsepower the nitrous system is adding to the engine. For instance, a “hundred shot” is adding 100 flywheel horsepower on top of what the engine makes normally. The horsepower level of the nitrous kit can is easily changed by swapping out metering jets. Most nitrous kits have multiple jets or “shots.” At ZEX we offer kits that start as low as 35hp and others that go as high as 450hp.

Maxwell: A good rule of thumb is 0.8lbs of nitrous oxide is used on a 100hp shot for 10 seconds. In other words, you could run a 100hp shot for a total of 125 seconds to run the bottle out of nitrous. The performance starts to drop off as the bottle gets closer to empty. Most serious racers keep a few full spare bottles on hand and swap them out when the one in the car is down to about 4lbs, or they notice that the power has started to fall off.“You won’t have to worry about nitrous freezing, but a cold bottle hurts performance. Nitrous works best between 900 and 1000psi, at around 85-90 degrees Fahrenheit, which is why a bottle heater is one of the best accessories you can buy. It keeps the bottle up at the proper temperature for the best performance.

Nitrous is perfect for those “Dude, I almost had you” moments when you need just a little extra power. Nitrous kits can be installed in just about any type of vehicle and are less costly than adding a supercharger or a turbo system. If you’re new to the idea of purchasing a nitrous kit, it can be overwhelming, and you may be unsure of where to start.Determining how big of a shot you need, depends on how much the engine components are capable of handling, and how much more power you need to achieve your performance goals.Nitrous is often seen on naturally aspirated engines and can be used on boosted engines. It has become a popular application to help spool the turbo quicker with the ability to shut off at a certain boost pressure.Maxwell: Installation is not very difficult, and ZEX includes very detailed instructions. A performance shop should be able to install a nitrous system in about 2-4 hours. An enthusiast working in his driveway or garage should be able to install it in a Saturday. Only essential tools are needed, such as a screwdriver, adjustable wrench, wire stripper/crimper, and hand drill. It is also a good idea to have a voltmeter on hand to check electrical circuits.

Maxwell: This can vary from car to car. So it’s best to ask a nitrous system manufacturer to see if your car requires any special equipment. A nitrous kit includes all the necessary components required to function, but there are some accessories, such as a purge kit or bottle heater, that enhance the system.

That said, releasing all of your nitrous to the atmosphere is a real bummer. When temperatures outside range from 80 degrees to 100 degrees, the temperature inside a car parked in direct sunlight can quickly climb to between 130 and 172 degrees. The best bet is to park in the shade with your windows cracked or bring the bottle inside when the outside temp gets above 80 degrees.

Maxwell: A dry system uses a nozzle to spray only nitrous oxide into the intake manifold. A wet system uses a nozzle to spray a mixture of nitrous oxide and fuel into the intake manifold. In general, if your car has a returnless fuel system, then you need a wet nitrous kit. Most cars, since the late ’90s, have returnless fuel systems, so wet systems are the most common choice.However, as bottle temperature rises, the pressure inside increases. Properly made nitrous bottles have a pressure safety disc that releases the gas before it gets to an explosive level. Beyond the differences in stem sizing and the materials chosen, there are several other differences in a jet. Lets start with the orifice location. In the image below you can see that even the placement of the small flow-restricting hole can be at opposite ends of the spectrum – literally. Traditionally, the orifice is near the face of the jet, but some manufacturers place it at the base of the stem. Diving further in to a “face orifice” jet, there are also the countersinks leading in to the orifice and then out of the stem. Each manufacturer uses a different size, depth, and angle on the countersink – if they even use them at all. Now, looking at the stem of the jet, you should see a counterbore that is larger than the orifice. This counterbore also varies in size and depth depending on the manufacturer. Using this counterbore exiting the stem creates a “ledge” where the orifice and counterbore meet. Besides damaging the orifice with your pin gauge, there are a couple of things that can damage your jets. Part of your visual inspection should include the face of the jet. Any dimples, rings, or gouges that catch when you run your fingernail across them will likely cause a leak. Another common one is that somebody finds an old jet in their toolbox, or acquire some jets secondhand that have deposits on them. The deposits may look dark/rusty, or have a white/green tint to them. If you find or have some jets like this, you can clean them up and they can be reused as long as the sealing face and orifice are in good shape. To clean the jets, soak them in vinegar for a night or two, then brush them off with a small brush or toothbrush and give them a good rinse with fresh water. Be sure to store your jets in a dry place away from any moisture, which can also cause a build-up on the jet. A long term cause of damage to jets is from fuel that contains alcohol. Alcohol is very corrosive and can affect all components of a fuel system, including the fuel jets in your nitrous system. Over time, the alcohol can corrode away the inside of your fuel jets orifice, causing the orifice to get larger and your tune to get richer. For this reason, we recommend inspecting and using a pin gauge on the fuel jets when you inspect the rest of your fuel system on an alcohol powered vehicle.

So, by now you’re wondering why all these things matter. Flow – of nitrous and fuel. The presence of this “ledge” created by the transition from orifice to counterbore and the depth/size/angle of the countersinks can increase flow, or reduce it drastically if the combination of them is wrong. On our own flow bench, we’ve witnessed the effect of having a mismatched set of jets and the effect it has on even cylinder distribution on direct ports. We’ve also experienced stepping up in jet size to theoretically increase flow only to see flow decreased because the larger jet featured a different machining process. The opposite can also happen, where a much larger increase or decrease is achieved with a simple jet change.

A pin gauge is a small metal rod that’s been measured for accuracy and is used to measure small diameters. There are two types of gauges, a ‘+’ and ‘-’ gauge. The minus gauge will fit into the orifice size you are measuring. For example a .036 gauge will fit into a .036 jet. If the gauge you are using is a plus gauge, the largest you would be able to fit into a .036 jet is a .035 gauge because they are slightly larger than the orifice. Though both type of gauges can be used to measure jets, most people use the minus sets for simplicity. Pin gauge sets are measured and rated for accuracy using one of 4 different ratings:Much like jets, not all nozzle fittings are created equal. For instance, a fitting for a short stem jet will not accept a long stem jet and vice-versa.

When choosing jets, it’s very important to source them from the same manufacturer because of the differences we just covered. First you want to visually inspect each jet. Make sure the material, face and stem tapers, and even the little ledge inside the jet all appear to be the same. Once you are confident you have a visually matching set of jets, you’ll want to use a pin gauge to measure the orifice of each jet to ensure they are the same size. Lets talk more about this pin gauge and its usage.Depending on who you talk to, you’ll get widely varied opinions on which is best and why. Unfortunately there is no empirical data to support any of them. Our experiences at Nitrous Outlet have led us to stick with brass simply because we feel it allows a better sealing surface at a lower overall cost. As we’ve already outlined, the most important thing you can do for your jetting is visually inspect and pin your jets to ensure you have a matching set – regardless of the brand or material.With all of the components a nitrous system may consist of, the jet is one of the most overlooked parts that can cause performance issues. In this article, we’ll dive into what a jet does, differences between jets, proper jet selection, and problems jets can cause.If you’re having issues with your nitrous system and have checked everything else, take a good look at your jets. If you have a jet that’s causing you issues, it’s always best to replace it.

For our purposes, a set of ZZ rated gauges will work great for measuring even the smallest of jets. When using a pin gauge on a jet, it’s important to not force a gauge into the jet or it can gouge the inside of the jet and make it unusable. Any damage or irregularity to the inside of the jet will cause it to flow differently. The pin gauge should go smoothly into the jet with no force.

A jet is a jet, right? Well, if you look at a jet as only being a device that provides an orifice to restrict flow, then all jets would be the same. However, not all jets are created equally. There are two main types of jets used in the nitrous industry – the ‘Long Stem’ style jet that has a longer and skinnier stem, and the ‘Short Stem’ jet that has a shorter and fatter stem. Both styles of jets are produced in either brass or stainless steel.About Us – Manage Preferences – Archive – Advertising – Cookie Policy – Privacy Statement – Terms of Service – Do Not Sell or Share My Personal Information –

A: We recommend at least 2500rpm as a minimum for nitrous system activation. This ensures that you will not have excessive cylinder pressures that could cause engine damage. The use of an RPM window switch ensures no premature activation. Nobody likes premature activation especially engines.

A: It is OK only if the engine is in good mechanical condition. The primary concern is to ensure that the engine does not consume excessive oil. Oil in the combustion chamber can cause detonation.

A: A nitrous bottle heater makes it easy to automatically maintain the optimum bottle pressure of 900-1000 psi. This ensures maximum hp and consistency for your nitrous system. Most companies have a very easy to install bottle heater that is thermostatically controlled and totally automatic.

A: Nitrous oxide is a gas that contains two parts nitrogen and one part oxygen. When the combustion process heats this gas, the oxygen is released. This extra oxygen then supports the combustion of the enrichment fuel the nitrous system adds when it is engaged. The additional fuel that is burned, creates greater cylinder pressure, which makes the extra horsepower you feel.A: For 4-6 cylinder engines, premium pump gas is required for safe use of your nitrous system when jetted up to 75hp. Above 75hp, racing fuel is recommended for maximum engine safety. For 8 cylinder engines, premium pump gas is adequate for nitrous system settings up to 125hp. Above 125hp, racing fuel is recommended.

A: The safest way to activate a nitrous system is by using a wide-open throttle switch. Most nitrous systems utilize this type of activation. Activating a nitrous system at anything less than wide-open throttle can greatly increase your chances for an intake system backfire. If you desire to use a push button for activation, most companies offers this as an accessory item. You can simply install the push button inline with the wide-open throttle switch.A: YES, Due to the increase in horsepower the nitrous system creates, the quantity of heat generated in the combustion chamber goes up. It is required that you install spark plugs that have at least two steps colder heat range. This helps to ensure detonation free performance when using the nitrous system. NGK has nitrous specific spark plugs available for many makes and models of vehicles.

A: The only accurate way to measure how full a nitrous bottle is, is to weigh the bottle. Nitrous systems achieve maximum power when the nitrous bottle is at least 20%, or greater, full. Below 20%, surging and lack of power occurs.A: Nitrous oxide is made up of 2 parts nitrogen and one part oxygen (36% oxygen by weight). During the combustion process in an engine, at about 300 degrees, nitrous breaks down and releases oxygen. This extra oxygen creates additional power by allowing more fuel to be burned. Nitrogen acts to buffer, or dampen the increased cylinder pressures helping to control the combustion process. Nitrous also has a tremendous “intercooling” effect by reducing intake charge temperatures by 15 to 25 degrees.A: A wet nitrous kit mixes nitrous and enrichment fuel by means of an injector nozzle that is mounted before the throttle body. This mixture is then drawn into the engine through the throttle body and intake manifold. A “dry” nitrous kit injects only nitrous with it´s injector while at the same time, increasing the engine´s fuel rail pressure to feed enrichment fuel through the engine´s own injectors.A: Generally the answer is NO. Most performance “chips” on the market advance ignition timing to gain additional horsepower. This additional timing, when using nitrous, can cause engine damaging detonation. The only exception to this are “chips” that have been specifically programmed for nitrous use.A: A nitrous purge kit clears the delivery lines of unwanted air and vapor and guarantees immediate power from your nitrous system. It´s also used to intimidate your competition and shows the world your nitrous equipped.

“I own a holden statesman V8 series II sedan and have been taking it to a genuine holden dealership for its servicing for about 4 years now. Approx. 2 years ago…I picked my car up after a service and they, much to my utter disgust and dissapointment, altered the timing to increase its’ so called performance. From the time I drove it out there car yard…..my machine was never the same againg….idling rough, stuttering, choking and was literally running like you were literally driving it over a cattle grid.. To this end, I took the car back on about 5 occasions and they continuously modified / changed the timing…but to no avail…the car was very sick !! I decided to take things into my own hands and came across this great business called ECC – at Northgate….I told the manager, Ryan the history of the car and the current status with respect to its performance and what it was doing….I gave him the service records and a folder of written information by myself that he found very useful. Today….my car literally runs like a V8 sewing machine….it is so very very very smooth and Ryan is the BEST operator that I have ever had the joy of dealing with….His personality, knowledge and desire to achieve the BEST outcome for his customer consumes him….and I for one, am just so grateful that I came cross ECC on the internet. Well done mate…you and your team really know your stuff !!!!! I am now using ECC for all my servicing in the future….”A: As long as the nitrous system is installed per the instructions and the set-up procedures are followed, there is usually not any increase in engine wear. Whenever possible, appropriate medical specialists should be consulted before administering analgesic/anxiolytic agents to patients with significant underlying medical conditions (e.g. severe obstructive pulmonary disease, congestive heart failure, sickle cell disease,[10] acute otitis media, recent tympanic membrane graft,[11] acute severe head injury[12]). Nitrous oxide is a colorless and virtually odorless gas with a faint, sweet smell. It is an effective analgesic/anxiolytic agent causing central nervous system depression and euphoria with little effect on the respiratory system.[1] Studies[4,5] have shown that children desaturate more rapidly than adolescents, and administering 100% oxygen to the patient for 3–5 min once the nitrous oxide in a closed system has been terminated is important.[4] National Institute for Occupational Safety and Health (NIOSH) research indicates that controls such as system maintenance, proper ventilation and good work practices can effectively reduce nitrous oxide concentrations in dental operatories to approximately 25 ppm (45 milligrams per cubic meter) during analgesia administration (i.e., the exposure limit recommended by NIOSH).Nitrous oxide irreversibly oxidizes vitamin B12, reducing the activity of B12-dependent enzymes such as methionine and thymidylate synthetases. This is the likely mechanism for adverse health effects reported in those individuals who are chronically exposed to trace amounts of the drug, such as infertility, spontaneous abortion, blood dyscrasias, and neurologic deficits.

There are two types of nitrous oxide-oxygen delivery systems: portable tanks on yoke stands that can be wheeled between operatories and larger, fixed-tank systems that are connected with a manifold system that can serve several operatories. Nitrous oxide-oxygen delivery systems are typically limited to a maximum of 70% nitrous oxide and 30% oxygen delivery; this helps ensure that the patient is receiving at least 9% more oxygen than is found in ambient room air.
