If you have a nitrous powered kit installed in your car then it is important that it should be installed perfectly. These kits are powered by nitrous bottles that are highly flammable and can explode if left loose fitted, so you just have to ensure that you are making use of right type of bracket to hold it in its place. When selecting one you just have to keep in mind that that bracket is an important component as it is going to hold the nitrous bottles to your car and so fitting is very much important. You should in fact never struggle to fit the nitrous bottles in the brackets every time you have to replace them. This bracket is designed such that it is helpful in holding the bottles in its right position, especially when driving your car in rough terrains.
In case you are just not making use of right size brackets then there are chances that while driving through the rough terrain the might fall off the car and explode. In most cases improper handling of nitrous bottle is literally responsible for most accidents. You can always make use of different types of brackets to get the nitrous bottles adjusted in wide variation of forms. There are also a number of such brackets that are available in the market that might offer you with such convenience that you can try adjusting the bottle in multiple angles. This is one advantage if you are having the nitrous kit installed on your motorcycle. There are also a number of brackets that can be placed at an angle of around twenty degrees from the nose of the bottle. This is good option in case you need to get it installed in motorcycle where the space is too less.

TESTING NOS SYSTEMS
Once you have your nitrous system installed, you must test the system to ensure adequate nitrous and fuel flow. This will ensure proper performance and reliability.
Start by ensuring that the fuel line is properly attached to the fuel solenoid and turn the fuel pump on. You can do this by turning the ignition key to the ACC position. Check for fuel leaks where you tapped into the stock fuel line and where the fuel line feeds into the fuel solenoid. Cure any fuel leaks, check again for fuel leaks and then disconnect the fuel line from the nitrous injector. Activate the system and check for fuel flow when the system is activated, and that the fuel stops flowing when you deactivate the system. If you don't get fuel flow, check that the fuel solenoid is operating properly — you should hear an audible click when the solenoid is activated; check that you have fuel flow at the fuel filter; and ensure that fuel line is not kinked, twisted or bent. If you do have fuel flow, turn the vehicle's ignition off and properly secure the fuel line to the nitrous injector.
Now open the release valve on the nitrous tank check for frost along the nitrous feed line. The frost will indicate a nitrous leak. If you find any leaks, close the release valve on the nitrous tank and cure the leaks. Open the release valve again and ensure that you've cured all nitrous leaks. Then disconnect the nitrous line from the nitrous injector. Activate the system and check for liquid nitrous flow when the system is activated, and that the nitrous stops flowing when you deactivate the system. If you don't get nitrous flow, check that the nitrous solenoid is operating properly; and ensure that nitrous line is not kinked, twisted or bent. If you do have nitrous flow, you can properly secure the nitrous line to the nitrous injector.
TUNING NOS SYSTEMS
Nitrous tuning is another simple procedure but you should first tune your engine without nitrous as you will be running without nitrous for most of the time. Tuning the nitrous system is quite straight forward — you start with the jet sizes recommended by the manufacturer of your nitrous system and gradually adjust the jet sizes until the air/fuel mixture added by the nitrous system is perfect.
So install the jet sizes recommended by the manufacturer of your nitrous system. This will be conservative and will err on the rich size (i.e., too much fuel), which is the safe side to err on. Run you engine for a while with the nitrous activated and then check each of your spark plugs to determine how the air/fuel mixture is burning. The correct air/fuel mixture will produce a brownish, grayish-tan color on the spark plugs. If the spark plugs have a sooty, black color, your air/fuel mixture is too rich and you should increase the nitrous jet to the next jet size. If the metal part of the spark plugs displays a bluish or rainbow coloration, go to a smaller nitrous jet size immediately. Repeat this test until your spark plugs display the correct color. Never jump up by more than one jet size on the nitrous side and never try to work your way down from a lean mixture — that's just looking for trouble and major engine damage. You can make more power by increasing the fuel jet size and then adjusting the nitrous jet size up until your spark plugs display the correct color again.
WARNING: Back off as soon as you get detonation and reduce the size of your nitrous jet!
You may also need to adjust your ignition timing as nitrous oxide makes the air/fuel mixture burn much faster than normal. Retard the ignition timing by 2° increments (i.e., less advance before TDC) until you feel a noticeable loss of power. Then advance the ignition timing by 2°.
Now that that's done, your nitrous system is installed, tested and tuned; all that's left is for you to enjoy responsibly — always enjoy power responsibly!
