What is meant by 30, 50, 100, 150, and 200 shots?

"Shot" is commonly used slang in the nitrous community and it refers for the horsepower your nitrous kit is set to.



How long will a bottle of nitrous last?

It depends on bottle capacity and the size of the nitrous shot being used. On the 75hp setting, a 10 lb. bottle will last around 10 quarter mile runs. On the 125hp setting the bottle will last around 6 runs. For power levels of 250 HP, 3 to 5 full quarter-mile passes may be expected. The formula for calculating your nitrous usage is: 0.8 lbs N2O X 10 seconds = 100 horsepower. I.E. If your system is jetted for 100 horsepower it will use 0.8 lbs of nitrous for every 10 seconds of usage.



How long can I spray the nitrous system for?

You could spray your nitrous system until the bottle is empty. However 15 continuous seconds at a time, or less, is recommended.



What are the differences between a dry nozzle and a wet nozzle?

The "dry" system uses the factory fuel injection to enrich the nitrous introduced into the engine. The flaw with this technology is that no matter how much nitrous arrives at a certain intake port it always gets the same preset amount of fuel, or if a fuel injector becomes clogged engine damage will result. The "Wet" technology introduces a precise amount of fuel and nitrous through a high tech mixing nozzle that atomizes the fuel to microscopic proportions. This allows every cylinder to receive a precise, homogenous mixture of fuel and nitrous, thus insuring a safe, powerful increase.



Do I need a purge kit?

A nitrous purge kit clears the delivery lines of unwanted air and vapor and guarantees immediate power from your nitrous system. It's also used to intimidate your competition and shows the world your nitrous equipped.



What is the safest way to activate a nitrous system?

The safest way to activate a nitrous system is by using a wide open throttle - WOT - switch. Unless a progressive controller is used, activating a nitrous system at anything less than wide open throttle can greatly increase your chances for an intake system backfire. If you desire to use a push button for activation, you can simply install the push button inline with the wide-open throttle switch.



What is the minimum RPM I need before activating my nitrous system?

It is recommended that at least 2500rpm as a minimum is needed for nitrous system activation. This ensures that you will not have excessive cylinder pressures that could cause engine damage.



Will nitrous oxide cause detonation?

Not directly. Detonation is the result of too little fuel present during combustion (lean) or too low of an octane of fuel. Too much ignition advance also causes detonation. In general, most kits engineered for stock type engines will work well with premium type fuels and minimal decreases of ignition timing. In racing applications where higher compression ratios are used, resulting in higher cylinder pressures, a higher fuel octane must be used as well as more ignition retard.
