The History of NOS and Nitrous Oxide
Anaesthetic
Nitrous Oxide was discovered by Joseph Priestley in 1772.
Humphry Davy in the 1790s tested the gas on himself and some of his friends. Initialy Nitrous Oxide is used in medicine for its anaesthetic and analgesic effects.
HIGH ALTITUDE: nitrous oxide (N2O) as a performance enhancement – World War II
Luftwaffe aircraft high-speed bombers, high-altitude interceptors were supported with nitrous oxide systems. Standart plane with nitrous boosted engine (GM-1 boosting) is ready to beat very high combat ceiling, but is limited by technological considerations. Focke-Wulf Ta 152C & H (Luftwaffe high-altitude interceptor) nitrous oxide tank capacity was 85 liters!
However, with the advent of jet propulsion at the end of WWII, the government’s interest in piston-powered aircraft waned, and for the most part, nitrous R&D was shelved.
HIGH-ALTITUDE RACE CARS? Secret rediscovered
There were sporadic attempts at using nitrous oxide in race cars over the next few decades, but since for the most part it was a clandestine, closely-guarded secret, and not too many people were aware of its existence.
Finally, in the 1970s, nitrous “came out of the closet”. It was the hot topic of conversation. Especially since a number of entrepreneurs brought systems to market that were highly erratic, at best. It was at this point in time when a couple of successful automotive technicians and racers, Mike Thermos and Dale Vaznaian, saw there was a potential for nitrous -done right.
In 1978 Mike and Dale formed Nitrous Oxide Systems, Inc., and the rest is history. They didn’t invent nitrous oxide -they simply perfected its use and elevated it to a position of prominence in the automotive performance community.
The company’s early years were largely spent demonstrating that nitrous oxide was an efficient, safe and reliable form of performance enhancement. NOS has always been known for thoroughly engineering each application (unlike our competition), using only the best quality materials, and producing kits that were easy to install and built for long service. And with enthusiast publications like Hot Rod, Car Craft and Popular Hot Rodding, among many, informing their readerships with in-depth tech features on NOS systems for various applications, the word began to spread.
Perhaps the greatest boost to the popularity of nitrous oxide was the advent of drag racing’s Pro Mod class. Early pioneers like Charles Carpenter, Bill Kuhlmann and Robby Vandergriff captured the imagination of race fans with their impressive performances with stock-bodied cars. And NOS was there for every performance milestone -the first 200 mph run by a “doorslammer,” the first 6-second run, etc. In fact, every single key performance milestone with nitrous has been set by racers using NOS systems.
Today, with over twenty years experience building nitrous systems for racing and street applications, NOS remains THE dominant force in the industry. A great deal of the company’s success can be attributed to its ongoing pursuit of perfection and extensive R&D efforts. Another key factor is the relationships that NOS has forged with leading racers and professional engine builders. Their input has served to keep the company on the leading edge of technology.
As we enter the next millennium, NOS as part of the Holley family, stands ready to serve its customers with the industry’s most complete selection of nitrous oxide systems and a technical support team that’s often rated as the best in the business.
How Nitrous Makes your Car go Faster
Simple version for racing newbies
If you are looking for PERFORMANCE on basic car – you are looking for bigger basic engine power output.
Ok – to gain more power from basic engine you need to get bigger combustion-pressure in cylinders (NOT compression rate).
Combustion-pressure is bigger when engine burns more fuel.
To burn more fuel an engine must get more oxygen. (Fire needs air [oxygen]).
The air you and any engine is breathing consists of 4/5 nitrogen and of 1/5 oxygen. As you see there is only 20% of oxygen – one of the three needed “ingredients” for combustion process. The other two are fuel and heat.
When you need more air (to burn more fuel) you either use a bigger engine or use a turbo/supercharger. Those two helps to stuff the cylinders with huge amounts of air but anyway – the ratio between oxygen and nitrogen remains the same. And anyone knows – mounting any charger on the engine properly costs a fortune.
So… now you see there is the best choice how to stuff your engine with more oxygen without stuffing it with useless nitrogen and avoiding insane turbo-bills! The Nitro system!
Nitrous oxide consists of 1/3 of oxygen. The EFFICIENT way to go isn’t it?
By cooling the air down nitro does somethig like the turbocharger – it raises the density of inducted air. The result? More air plus more oxygen. BINGO!
With more oxygen to support combustion process you only need to give the engine more fuel. And this is as easy as killing bunnies with the axes…
Summary. More oxygen + bigger air density + more fuel = bigger combustion pressure = more engine output power = your ass moves faster after the light turns green!
Don’t use pure oxygen. You don’t want to be fried like a chicken!
