Why does my engine need more fuel while using nitrous?

The fuel, or gasoline, is the source of the additional horsepower. The nitrous' job is to provide the oxygen to allow the fuel to be burned.



Is a bottle heater good?

A quality bottle heater is essential to proper nitrous system performance.



How much pressure should be in my bottle?

Between 850-1050 PSI.



Are there any dangers or things to stay away from while using nitrous?

No more than an additional 20 horsepower per cylinder be used on a stock engine, with a stock fuel pump. Always be sure you are using clean, uncontaminated nitrous. Also, be sure you have the highest octane fuel available, I.E. 93 octane premium for, stock compression, street cars and the highest motor octane fuel available for competition type vehicles.



Can a nitrous system be set up to shut down once the brake is depressed?

Yes, if the user wires his system with a double throw-double pole relay placed between the arming switch and the wide open throttle switch that is activated when the brakes are applied.



Do I have to change my spark plugs after installing the nitrous system?

Yes, due to the increase in horsepower the nitrous system creates, the quantity of heat generated in the combustion chamber goes up. It may be required that you install spark plugs that have a colder heat range. This helps to ensure detonation free performance when using the nitrous system.



Are drag racing launch techniques any different with nitrous for Automatic and Manual transmissions?

Depending on the traction available the launch techniques are the same, however with the increased torque and horsepower generated by nitrous usage, sometimes is necessary to delay the nitrous onset for a brief period.



Does nitrous increase cylinder temperatures and combustion chamber pressure?

No, cylinder temperatures should stay the same when the correct nitrous air / fuel ratio is used. Yes, increased cylinder pressure equals increased horsepower.



Can I use nitrous on my high compression engine?

Yes, but the proper octane fuel must be used to prevent detonation.



How high must the RPM's before activating nitrous?

The RPM level is not as important as is the motors ability to rev freely when the nitrous is engaged, I.E. If the vehicle is in low gear, nitrous can be engaged at any time, but if the vehicle is in a higher gear moving at a slow speed when the nitrous is engaged the engine will detonate and damage will occur.
