i want to put nos on my z400. I know it isnt the best thing for the engine, but i was wondering. How would a piped and jetted z400 that has nos on it do compared to a yfz 450 with equal mods except for the nos. and where can i get a kit that comes with everything i need

 

I have the boon dockers nos kit when i just had a pipe, cams, and rev limiter and it walked away from the yfz-450s BELIEVE ME!!! I gave my friend with his yfz-450 four quad leangths head start and i still ripped him a new one.[img]i/expressions/face-icon-small-wink.gif[/img]

 

thanx for the info, what size bottle did you get for yours and if it was a smaller size do you wish you got a bigger one, and was the install super hard
dont you run like stock unless you start spraying, its not like on nos the whole time is it? not sure, new to this stuff

 

bump

 

I'll give you some info about nitrous. First of all, it's called nitrous, not nos. That makes you sound stupid when you say it, and if you talk to any old-school gearhead, they'll immediately write you off as a pilgrim (read: newbie idiot). N-O-S is an acronym for a company called Nitrous Oxide Systems. Ever since that stupid Slow and Bi-Curious movie came out, every tard says "naws."

Now that I've tried to set you straight, nitrous oxide is a great little compound that Mother Nature has blessed us with. The way it works is that it provides extra oxygen for the combustion reaction. Nitrous by itself it not flammable, contrary to what Hollywood would have you believe. The heat of combustion breaks apart the molecular bond between the oxygen atom and the two nitrogen atoms. This free oxygen then oxidizes a hydrocarbon (fuel) molecule, which produces carbon monoxide, water vapor, and heat. The nitrogen atoms do nothing but take up space and get hot before being expelled out the exhaust. It sounds like you can just spray nitrous in the intake and not have any trouble. Wrong. You have to provide extra fuel molecules to compensate for the extra oxygen, otherwise you will have a very lean mixture, resulting in severe engine damage. Nitrous only works if it is tuned correctly. Not enough fuel? Meltdown. Timing a little too advanced? Boom. The timing has to be retarded when you run nitrous to prevent the flame front from running back out the intake port before the intake valve fully closes, igniting the air/fuel mixture in the port. If you've ever seen a drag car blow a fireball out of its hood scoop, this is caused by errant timing. You asked if when you install a system if it runs continuously. Nitrous is usually triggered by one of three ways: a full-throttle switch, an RPM activated switch, or a manual switch. Nitrous is only on as long as either the engine is at full-throttle, the RPMs are high enough, or your finger is holding down a button. A small nitrous system will not affect normal use in any significantly negative way. IOW, it will ride the same as it did before without the nitrous when you're not on the bottle. The physical size of the bottle has nothing to do with the performance of the kit. That's determined by the jet sizes. It just allows you to use it more often before refilling the bottle. Pressure is more important than quantity when dealing with small HP systems. Don't let what I'm saying here deter you from running nitrous. People have been using the stuff since before WWII, so it's obvious that it's not as bad as it sounds. Just make sure that you know what you are getting into before you go nuts and shell your engine. And please stop calling it "naws."
