^^ going on that.
since the automatic has only 4 gears, i would assume its ONLY safe to spray in 2nd and 3rd?? Not only that, we wouldnt have to worry about spraying in the wrong gear besides 1st, becuase when we floor it The tranny automatically downshifts, RIGHT??
so to sum it up for automatics, the only things we really need to have / worry about is:
-- not spraying in first
-- having a window switch
is that all? feel free to correct / add

Also, this might be a dumb question... but are there two switches 1) to spray and 2) to clean the lines (purge)? and if there are, are they included in the kit? thanks>

Purge kit is usually purchased separately from a n2o kit and they WILL have separate switches. Depends on where and who you buy it from.
BTW...gauges go for like 45-50 bux on ebay. that's ur price range. Get an in cabin n2o gauge and an a/f gauge (wideband is better, but narrow band is less expensive).

Window switches are for those people who have a habit of or are scared of redlining too much, too often, or spraying at too low of an RPM. I don't see what's so hard about lookin at the tach before you spray?? Window switches are for people that want like an "added safety feature". But you don't NEED it. All you have to do is watch ur RPM's. Simple as that.
And you can spray in first. Hell i did it all the time at the track. Launched the car with the nitrous activated (then again i have a manual). I don't recommend it on the street "much" because you will have no traction whatsoever. If you're automatic then it doesn't matter because most if not all of your races will be "rolling"races...that is...if you want any advantage/traction whatsoever.

Rep Power: 0 I know you shouldn't spray for more then 15secs, which is less then it should take to do a 1/4 anyway but how long should you wait in between these 15secs?
like would nitrous be suitable for circuit, like if you got the a/f,n20 guages and like oil temp and oil press, and water temp to monitor all your s#!t so you dont over do it.
anyone w/7thgencivic runnin nitrous for circuit that I could talk to?
My friend is runnin a Si/SiR Turbo on the circuit and I am not sure if the n2o will cut it
I just want to keep up with him.

Rep Power: 0 I got another question if you are equipped w/remote opener and you have the bottle closed and the system off can you just turn it on at any time like when your moving and spray or do you always have to be at a stop when you activate the system?

You can turn it on at ANY given moment. Whether you're moving, or at a stand still, does not matter. Thats the whole purpose of the remote bottle opener. To open the bottle at anytime, even if its out of arms reach.

From what I understand, the 15-20 second rule is there not because your engine cant handle it, but because the solenoids are usually only designed for intermittent use. Using them for any amount of time beyond that can ruin them. Even if you could use it for longer than 20 seconds, you probably wouldnt want to because of the loss of pressure inside of the bottle. How long do you think you're gonna need to be spraying for? If its for an extended period of time, you will probably end up running the bottle empty. Nitrous is most useful in drag racing IMO.

Q: OK, so no chip, but what about nitrous with a turbo or supercharger?
A: First off, for the last time, THERE IS NO SUPERCHARGER FOR THE 7TH GEN. Most people only use nitrous with turbos to help spool up the turbo. If you don't know what turbos and spooling are, search, its lengthy and would be another thread in itself.

Rep Power: 0 I ran a 14.4 in the 1/4 with a 2.3 60ft time slip on a 75 shot, NX wet kit with a stock clutch slippin and some dead drag radials. Those who know me on this forum probably already know this. Its nothing new. If you're looking for a quick fix on a stock block that is cheap to install and easy to win from a dead stop then nitrous is the way to go, but if u want a good overall increase in daily driven power on a stock block then turbo is the way to go, but you still wont be as fast as some of the other honda's with swaps already done that all already match the same torque-to-weight ratio N/A as you are already carrying with your turbo. In other words..if u dont plan on rebuilding the D17 and u just wanna win some from a dead stop then go with nitrous, but if u want more effiicient power across the board on a daily basis then go turbo.

Rep Power: 284 From what i hear dude the dry kits are WAY too dangerous. Running a danger of having an uneven about of nitrous in each cylinder plus the issue with the factory fuel pump not being able to supply the extra needed fuel, if i remember right something about our injectors or SOMETHING thats has a return feed..........meaning the extra fuel would be routed back to the tank or pump. Then that would cause ur engine to run lean (i think) and lean+nitrous-->BOOM! Long story short, me and coutless other 7thgen-ers would HIGHLY recommend a wet kit. The extra needed fuel gets mixed and atomized in the spray in your intake runners. Wet kits are a little more pricey, but would you rather spend a few extra hundred dollars or a few grand replacing your engine? If i'm wrong or too vauge about anything above then somebody please correct me. Oh, and yes, if you still do stick with the dry kit then yes, you can intall it onto your stock airbox, but most peeps would recommend on upgrading your intake.

K, i got a question. I understand that with nitrous i shouldn't have any ECU upgrades or the Venom 400 or anything else that advances the ignition timing, but would other engine mods like a crank pulley, or undrive pulleys put my engine in risk?? Some insight would be very helpful

I wouldnt think so, not unless you plan on using the nitrous while they're doing their emissions test.

Rep Power: 0 so will denso IK20's work and if not what spark plugs are compatible besides the copper ones. A lot of people around here say that the platinum tips or whatever are better than using copper or nickel. Does that just apply for stock cars or for cars with nitrous too??
