Nitrous Help For A Newbie?

Please provide pics of all mentioned parts.

Basically, a window switch is a nitrous control system that will only allow the nitrous to spray during a specific RPM range, or RPM "window". Reason being is that nitrous obviously needs to be SUCKED into the engine. If RPM's are too low, there isn't enough velocity to sufficiently suck all the nitrous into the combustion chamber. Spraying too low results in the nitrous pooling in your intake, which is almost a certain backfire that will grenade your intake.

Nitrous flows much better the hotter it gets, thats where the bottle warmer comes in. It heats the N20 to efficiently get it to the motor faster.

A purge is required to get all of the air out of the lines, again this is essential for getting the N20 to the motor quick and efficiently

And finally, a nitrous system isn't armed all the time. Every nitrous bottle has a valve, much like the valve on your gas grill. There are two ways of arming the system......either opening the bottle with your hands (doesnt really work when you encounter surprise races), or having a remote bottle-opener so that you can flick a switch wherever/whenever and the valve is opened
