In 2021, the then home secretary, Priti Patel, asked the independent Advisory Council on the Misuse of Drugs (ACMD) to review the harms of nitrous oxide with a view to a potential ban. While supplying nitrous oxide for its psychoactive effects is already illegal under 2016 legislation, the gas has legitimate uses, primarily for the production of whipped cream or for freezing food, and it is widely available online. These actually inject the nitrous into the intake system. They need to spray a mix of fuel and nitrous together depending on whether the kit is a wet or dry system. Distributing the nitrous is easy due to the high pressure. It’s the fuel that’s the problem to get right, so these injectors are designed to give a crossfire spray pattern which is better for atomization of the two substances. Lines We have a range adaptors available allowing us to refill most NOS, Nytrex, Cold Fusion, Nitrous Express, Highpower and Wizards of NOS bottles.

The blowdown tube is mounted to the pressure release device, which houses a disc that ruptures at approximately 3,000 psi. It vents the nitrous outside the car.” Nitrous has to change to a vapor [at the engine] to be functional. You want to get as much of the nitrous you can to the nozzle, and it needs to be liquid. When it’s in the bottle, and you’re getting 950 psi, that’s when it becomes a supercritical fluid, where it’s neither a liquid nor a vapor and kind of both at the same time. As soon as it goes above or below that critical temperature/pressure point, it turns into all liquid or all vapor. You have the balancing act of the two to get it from storing it in the bottle to getting it into the engine where you can use it—getting the nitrous from the bottle through all the lines, fittings, and solenoids. In a completely full bottle, it has 10 pounds of nitrous in it that is all liquid. As it gets used up, above the liquid is the vapor, and that’s what’s developing the pressure. There’s a balance between pressure and temperature, and liquid and vapor. Every time it goes through a transition, from the bottle to the nozzle, there can be a pressure drop, and if the pressure drops enough, it turns from a liquid to a vapor and screws the flow up,” says Wagner.For this reason, it’s easier and cheaper to install and it will come in more progressively. This makes it easier on drivetrain components and gives less chance of clutch slip. However, as the nitrous has further to travel before it reaches the cylinders, it has more chance of turning to gas. In addition, on some applications it isn’t possible to use. If the throttle body is mounted lower than the inlet valves, for instance, then the mixture will have problems reaching the engine. If there is no single shared throttle body or carb then this kit can’t work either. Nitrous oxide accessories Bottle warmers When stored in the bottle, nitrous oxide is primarily a liquid, and when stored at room temperatures produces between 600 to 800 pounds per square inch of pressure. To maximize the volume exiting the bottle, the temperature is raised by a bottle heater (wrap-around or water-bath) to produce a bottle pressure of 900 to 1,000 pounds per square inch. As the system opens to the engine, it is injected as a gas that consists of two parts nitrogen and one part oxygen. It is this oxygen molecule that allows increased power from an engine when the appropriate amount of fuel is added to the mixture. It’s a bit more complicated to deliver the nitrous to the engine than one might think, though. Please note we will strictly only fill Nitrous bottles for use in motor vehicles, and reserve the right to decline refilling any bottle which we deem to be unsafe. A 2 Kg bottle (5 lb for those who don't do metric or fractions) should weigh 2 Kg more that the empty weight when filled and likewise the 5 Kg bottle should weigh in at 5 Kg more than the empty weight.

This is the theory behind the use of Nitrous Oxide(NOS) canisters in car engines – note that these are mixed with toxic chemicals so don’t try whipping any cream with an automotive NOS kit! – but the beauty of thecanisters is their size. They are tiny and light but contain quite a lot of Nitrous Oxide gas. Doctors have warned about an increase in spinal cord and nerve damage caused by the drug, including paralysis.

Toby forget the formulas etc., just weigh the bottle when it's empty and then add the contents weight for the full weight - it's that simple! Discarded nitrous oxide cylinders are a ubiquitous sight on high streets and at festivals, with almost one in 10 16- to 24-year-olds reporting having taking the drug in 2019-20. The plume of gas you see some cars give off on the start line at the drag strip is simply gaseous nitrous being vented off to atmosphere through a purge kit. It brings liquid up to the solenoid ready for immediate use. That being said, only bigger kits using braided lines realistically need it, otherwise it’s just for the pose factor. Controllers
