Although this may seem like a very basic factor, failure to thoroughly read the instructions is the number one reason your system installations will not be successful. Read ALL the instructions included with your system BEFORE you do anything at all! You may find that you need to change something on your engine or find that we’ve designed something new that is different from some of the systems you may have seen in a magazine article. Save time and headaches by taking the time to thoroughly read all of the instructional materials. Call the NOS tech dept. if you have any questions.
Always start conservative. Follow our recommended jet combinations and start with the lowest level if you have an adjustable system. It only takes a few moments to change the jets so don’t take unnecessary risks by starting at the highest level.
Be realistic about how much power your engine will handle. Don’t get carried away here. Only you know exactly which components are in your engine. If you are unsure about those components, you can call our tech line and one of our highly experienced tech personnel can help you to decide what is safe for your particular combination. If you don’t know what's inside your engine, then you are most safe by assuming that the components are factory stock and choose the correct system for that application.
The power comes from Fuel. The additional power is set by the amount of additional fuel your system supplies while the nitrous system is in operation. If the fuel isn’t there, the power won't be either and no amount of nitrous or anything else can bring it back.
There are two controls typically available to manipulate the amount 0f fuel available during system use; the fuel jet size and the fuel pressure. The correct fuel pressure is read while the system is flowing fuel. Some fuel pressure regulators give false readings because the pressure reading will creep up when the system is not activated. When this happens, the actual flowing fuel pressure will be much lower than expected and can cause problems.
When problems with misfire or detonation are encountered, ALWAYS reduce the size of the nitrous jet first! Remember that the power comes from the fuel, not the nitrous, so trying to cool things down by adding fuel simply adds more power and complicates the problem. Carburetors jetted over-rich run cooler and release less power. Nitrous systems jetted over-rich will possibly just release more power, so if you run into problems, reduce the size of the nitrous jets first.
When you check your spark plugs for signs of how your system is operating, CHECK EVERY SPARK PLUG, not just the easiest plug to get to. No two cylinders ever run exactly alike. Nitrous has the unique characteristic of cleaning the spark plugs very well and leave them looking like you just installed them. If there are any signs of detonation such as tiny silver or black specks deposited on the porcelain, reduce the nitrous jet size, if the ground strap of the spark plug exhibits a bluish-rainbow coloring, reduce the nitrous jet size. If the ground straps shows signs of melting, reduce the nitrous jet size and change to a spark plug with a shorter and thicker ground strap.
If your system suddenly begins to experience problems even though you haven’t changed anything, the culprit is most often a clogged nitrous or fuel filter. The instructions that came with your system contain information about where the nitrous and fuel filter screens are located. Check them periodically. NOS systems are calibrated for optimum performance with a bottle pressure of 900-950 psi. The pressure will change with temperature. NOS heater kits are thermostatically controlled to keep the bottle near 85 F to provide correct pressure. Kits available for the most popular-sized bottles, with both 12-volt and 110-volt heaters offered.
If you experience any problems you don’t understand or can’t cure, don’t hesitate to call our tech line. We’re here to help you get the most from your NOS System.
