| Nitrous |
|
Short for nitrous oxide (N2O), the same stuff that the dentist puts you to sleep with. When injected into an internal-combusion engine, it provides extra oxygen (being about 35% oxygen, as opposed to air which is 21% oxygen), and gives the engine a BIG boost in power.
|
|
| Nitrous Oxide |
|
Nitrous oxide is comprised of 2 parts nitrogen and one part oxygen (36% oxygen by weight). When the nitrous oxide is heated it breaks down and releases extra oxygen, However, it is not this oxygen alone which creates additional power, but the ability of this oxygen to burn more fuel. By burning more fuel, higher cylinder pressures are created and this is where most of the additional power is realized. Illegal to use in any NASCAR stock car series. Both A.J. Foyt's and Darrell Waltrip's qualifying times in the 1976 Daytona 500 were thrown out because of evidence of Nitrous Oxide use.
