Nitrous on a 3.9L '06 Impala
A friend of mine is hungry for more power from his 3.9L '06 Impala LTZ.
Since there are almost no mods available for that engine at this time (intake and exhaust only), I suggested nitrous.
Nitro Dave suggested this 35-150 shot single nozzle wet kit, plus a window switch and the needed accessories.
Anyone care to guess at the largest shot it could handle "safely"? What accessories would you consider "needed"? Are there other kits he should consider?
I know close to nothing about nitrous systems. I know about nitrous and how/why it adds horsepower, but nothing about the systems. AFAIK my friend knows less than I do. What does it typically cost to fill a 10lb bottle, and how long does it last?
Educate me!

rule of thumb is a stock motor can only handle 20h.p. per cyl to be safe
bottle depends on how much you use it etc. prices vary from where you are located $4.78/lb. where i'm at
Even tho I don't use nitrous

I have heard 20hp per cyl and up to 50% of your NA power.
Both are just rules of thumb and you should do lots more research.
That being said what does the New impala make?
Rough guess I would say a 75 shot would be pretty safe and 100 doable.

Nearly every post in this section lists them:
**Required IMHO
WOT Switch: Come in many forms, ensures activation at wide open throttle only
Window Switch: You know that one
Colder plugs: One step colder plug, no platinum.
Fuel pressure safety switch: I think these are universal for fuel injected cars. Cuts the system off if the pressure drops below a preset point.
**Not required but strongly recomended
Bottle heater: With a full bottle I can't get the needed @ 1000psi unless its 90 degrees or better out. If you get a heater YOU MUST get a pressure switch for it too. Acts as a stat to turn the heater on/off to keep the pressure at an ideal level.
Purge kit: With a purge you can vent air out of the lines before actually spraying. If you don't have one the system engages a little wierd. On a wet setup you will feel a bog at first because it gets super rich, then a kick when the n20 finally gets into the motor. A purge will minimize this.
Ignition control: On our cars with stock motors pulling timing is usually not required. If you want to spray a large amount or have many other mods though this is a good idea. (I know nothing about the Impys ignition system)
**Not needed but fun
Progressive controller. This will add $$ to your setup, but are really neat. You can adjust pretty much anything about the system with one.
Blowdown tube: With a car having a trunk I don't think one is required. All bottles will have an emergency burst valve that will pop if the pressure gets to high. Keeps the bottle from exploding. A blow down tube vents outside the car incase this happens
Bottle opener: There are several on the market now. Remote opener. You flip a switch and its open. Used by lazy people or those that want to hide their stuff. IE if you want to keep it a secret on the street this would save you from having to open the trunk and go turn the valve on your bottle. I don't have one because my bottle is mounted within arms reach of the driver.
Others can add more toys to the list. Be aware that a "complete" nitrous system can get quite pricey. I have run with as little as a WOT and window switch. Without these two you run the highest risk of blowing the motor.

It costs me $42 to fill up my 10lb bottle in my area. One bottle lasts me less than two minutes. It all depends on bottle size, nozzle size, bottle pressure etc.. Expect to go through at least a bottle a week when it's first installed. After the newness wears off you may find that you are refilling less often.

I can get $3/pound in my area.
On a 100 shot @ 2 minutes seems to be right. There is actually a formula somewhere too.
2 minutes doesn't seem like much, but. At the track say that impy runs a 14 flat ?? Well there are a full nights worth of races in the bottle.
On the street you will typically use even less. If I play on the interstate I am usually spraying from mid second to the top of third. By that time its way past the posted 70mph. So 5-6 seconds maybe? I probably waste more by purging the lines empty after closing the bottle.
