Nitrous Oxide

From GM Wiki

Overveiw

This is in my opinion the easiest to install, and probably one of the easier systems to tune. Install for a basic plate or single nozzle system on average is about 4 hours, and has instant results, but start low and work your way up. Nitrous has received it's bad name from too many people throwing a system in their cars, putting the largest jet(s) in they can and going, this is a sure way to get poor results and usually ends up damaging something.

Some things to consider

General rules of thumb (but not exact science) are: retard timing 2 degrees for every 50 HP increase in "shot" I.E. a 50 shot would need 2 degrees of timing retard, when "spraying". a 150 shot would need 6 degrees of timing retard, since: 150/50=3 3x2=6, that easy. Some engines (combinations) may require more or less retard for the same size shot, but this is where tuning for maximum power comes in. A HP "shot" on a stock engine (with cast pistons) should not exceed 50% of max total rated power. I.E. Engine rated at 180HP 180/2=90, again this will have to be determined for each engine, I know some people have not been able to run more than about 30% without having problems, others have been able to run as much as 75% and have great success.

When you should and should not spray

Never spray at under 3000 RPM and have the nitrous stop spraying BEFORE the rev limiter, this is where "window switches" that read RPM are a great asset. Only spray at WOT, there is no need to spray before this point as you just need to push down on the pedal more if you want more power (RPM). Really why would you need any sort of added power at anything less than WOT? It is also a great asset to know what kind of limiters are on your vehicle, such as a spark cut limiter or a fuel cut limiter. As far as I know, all 660s use a fuel cut for both RPM and speed limiter, which makes running on nitrous at above these RPM's and speeds very touchy and should not be attempted, since the biggest reason for bowing an engine is running lean, which a fuel cut will do. More info can be found on manufacturer sites.
