I still like the sound of “NOS on my RC”. Some facts and points to ponder: (I’m attempting to cover most of what I’ve read) The NHRA nor the IHRA has not banned N20 except in anything dealing with a “Stock” class. This includes Stock Eliminator, Super Stock Eliminator, Super Stock Modified and Pro Stock. Everyone else is free to run whatever they like (with strict no-no’s on illegal fuels). The Nitro cars (Top Fuel Funny and Dragsters) don’t need it and I’ll get to that later). This information comes from memory and experience only so if I miss a figure or what have you, sue me, correct me, whatever. (I deal with this stuff everyday) Nitrous Oxide CAN burn the skin but its frostbite not like flesh eating bacteria. N2O is not, under any circumstances, flammable. But under certain circumstances it enhances flammability or combustibility when it comes to engines (similar to that of oxygen to acetylene). N2O is 2 parts nitrogen, 1 part oxygen. Once it has reached a temp of somewhere around 570 some odd degree’s, it breaks down and starts releasing O2, and bunches of it, which makes it mostly O2 at that point and beyond. With this added O2 in an engine cylinder, cylinder pressure increases and can increase to a breaking point. This is where the nitrogen comes in, it acts as a buffer, it actually helps keep the cylinder pressure “beat down” at bit. If you tuned you carb overly fat (rich), it’ll be lazy, foul out plugs, smoke terribly, and get poor performance. Any engine can only burn but so much fuel at a given time. N2O allows and needs a fat condition. N2O enables an engine to burn fuel that it can’t burn by itself therefore N2O is a catalyst. The more fuel an engine can burn the more power it will produce. Lower temps: Of course the engine runs cooler. From the time N2O (in liquid form) hits the intake (or carb), it’s minus 120 something degrees. What do you expect? Ever wonder why the Nitro methane funny’s and drags don’t use N2O? Go have a look at the periodic table. N2O is lesser than Nitro methane. And wanna know what’s funny? Nitro by itself (although flammable) is very hard to get to burn. In fact, it needs pre-warming and to be compressed (I haven’t the slightest idea of what temps this stuff is combustible). But in an engine, when mixed with a little fuel (gasoline), the “quench” or compression that occurs when the piston approaches top dead center on a compression stroke, all hell breaks loose. Since nitro methane is the greater fuel, nitrous would ultimately slow the car down. Not to mention keeping a head gasket on it would be forever more impossible. I’ve lost my train of thought, if you need clarity on any of this or any questions pop into your noggin’, ask away. I won’t hand you any speculation, only facts.
