Properly using nitrous

I have been wondering this for a while. If you have a nitrous shot in your car, when is the best time to use it? I guess I just really don't know anything about this subject, hence why I am not going to do it :naughty:
But for real, if I had this set up on my car, and shot the nitrous, how long does the shot last? What would happen if I shot it to late and had to shift, would I redline when I put the clutch in.
If your racing in the 1/4 when do you hit it?
Thanks in advance.

You open the bottle, flip the activation switch, and a sensor hooked into the TPS (throttle positioning sensor) on the ECU tells the kit when you're at full throttle, and sprays. Under 3,000rpms is bad on your engine because it's not turning fast enough to suck in all the juice. This will sometimes make it pool up in the intake manifold and blammo, you can cause a reverse backfire, possibly making your manifold rupture or shatter.
So to answer your question, use it in first gear after 3k up to near redline, the just plow through the gears like you would any other race. Shooting n2o like in the fast and furious is totally rediculous, if that's what you're referencing your question to. They do have 2-stage kits like that, but for your Civic it's not needed. Oh and if you plan on keeping your engine for more than 5 bottles (which last about 2 days - a week per bottle) install forged internals and get 2-step colder spark plugs. Nitrous Oxide burns hotter and stronger inside your combustion chamber and will melt your stock plugs, bend your rods, fry your rings, and/or blow your headgasket if your engine isn't built for it. I know you said you're not going to do it, but my advice everybody else in question: don't waste the time/money on some cheap thrills.

Sounds intense. So if you have a 75 shot, your going to have an extra 75HP from 3k to red line?

Yeah since I have no idea what I'm talking about.
As for the 75 shot, you'll definitly want to have internals installed along with a larger fuel pump, a 4 deg bump in timing, and a new clutch to be able to grip the instant kick in hp. Also, the jettings aren't too accurate because if your bottle is warmed up and your at 1200psi or something, it will shoot more through the jetting than if it weren't, making it like an 85 shot opposed to a 65-75 shot cold. The main point is, nitrous is cheap hp but to prepare your car for it isn't.

Well thanks for the bid of confidence but Ricochet has cobered it very well. He is one of the more knowledgeable members on the forums.:thumbsup:
The only thing I would like to add is that if you have a wet kit then try to keep your bottle from getting above 950psi or so or your fuel to nitrous ratio will be off and you will be running lean.

I have some first hand experience to add myself. Be careful when you first get it, get use to how much faster it winds out the engine, before you race it. I didn't realize it and I was racing the day after I got mine installed and missed 4th b/c of it. There went my engine....$1600 later I learned my lesson. I hope I can save someone else from doing that.
