I wouldn't use Denso Iridiums w/ nitrous, I kept getting misfires. NGK V-powers worked for me.

Dry shots are just that. DRY, the air going into your car is cooled tremendously by the n2o <like a fridge> and it is the colder air that causes an increase of power more than the actual n2o itself.
also the shot is based off of a full bottle. as you use it you wont feel as much of a punch. i think the recommend pressure is 900psi <dont quote me on that>

I would also recommend a blow-down kit. the n2o bottle has a burst disk that will blow in an extreme pressure situation the blow down will keep you from being exposed to it in the car. It diverts the gas out of your trunk.

All you need to do to change your fuel deficiency is a FPR <b&m makes one>
If you are not going over 55shot you dont really need to worry about going lean. 35-55 shot should be fine on stock inj and stock fuel pump.
anything over 55 you should prolly either go wet OR get bigger injectors.
I have a friend with a 99si on a 75 dryshot stock injectors and he has 0 issues. He has the FPR tho so he can correct any fuel mix issues he has.
If you are REALLY worried about it or want some crazy *** power do a motor swap and build it out.
and I am pretty sure higher compression pistons will help with the n2o

You sound like you're a little lost in the n2o department...if you're suggesting that a dry kit is a better choice for our 7th gens and is just as safe as a wet kit, I'm sorry but I think you're outta your fvckin mind. Using a dry kit on our 7th gens does cause our a/f to lean out. Ask anyone on the board here who has ever used one. A wet kit doesnt require a FPR on our cars either. I can bet your friend HAS encountered a couple issues along the way using his dry kit on his SI regardless of what he has told you. Also, I can run my bottle damn near empty and still get just had hard of a punch out of it as I can when its full as long as the bottle pressure is high enough.

Have you had any dyno time to tune your a/f ratio??

wet 50 and 35 causes our cars to run really rich, around 15.8,I had to use a 50 shot nitrous jet and a 35 shot fuel jet to get a a/f ratio of 14.7, which IMO is still to rich. You could easily get away with using a dry 35 shot using no fuel mods, a/f ratio may be a little on the lean side, but not enough to cause detonation.

thiscrackerntam

I personally havent, but I know someone who has with the same kit with the 75 shot and they were not running too rich at all (between 11 and 12) What was your bottle pressure at during those runs? Thats a very important factor regardless of what shot you're using. If the pressure is between 900-1050psi with a wet kit, then you shouldnt be running rich period.

denso iridium ik20 plugs are more than enough to use. I personally went to vic edelbrock headquarters and asked them if this was ok and they said yes its more than ok.

thiscrackerntam

^^if those cost any more than the NGK bkr7e I use, I say they're a waste of money and you probably dont get any noticable difference in power either.

they got a dyno of like 2whp gain with just bolt-ons or stock I forgot. I got them for like 8$ a peice

Could somebody answer this question....I'm in the same boat.

N2O NooB questions:

Can activating the a N2O shot right when you launch with an auto hurt? In what way if any?

Can us auto guys flip the switch of the wet kit at a light when we are stopped, and then when he hit WOT the system will activate? Will this hurt the engine in any way?

What other precautions would us lowly auto guys have to take if we want to spray?

Do all kits come with a remote bottle opener?

<thanks>

Sombody mentioned if you can use ur factory fuel line/pump to feed your wet system. I have a 04 Civic EX and I had to install a inline fuel pump to help the system run in the sweet spot. By using your stock line you will run lean, I ran a50 and 75. Clutch, will go in no time specially w/ a 75. It sucks too my car only has 7,000 miles :-(
P.s. I run a NOS wet system with remote opener, purge, a/f guage.

I'm also one of those who ended up with an auto and was wondering what all I need to look out for.

well after many months of research i finally got my kit. NOS 75 wet kit

myGFgottaCIV

you shouldn't use any type of precious metals when using nitrous. stick with copper plugs, ngk coppers are fine.

02 civic

I know that 'Wet' Nitrous contains both Nitrous and fuel (helps to keep correct AF ratios), but I'm wondering where the fuel comes from? (Do you need ot tap into the cars fuel line, or is it actuualy mixed within the tank?) from the pictures I've seen of kits, it looks like there's 2 lines (usually red and blue) that feed into the nozzle...so I'd assumed that the fuel line is coming from the car's fuel line-is this right?

One more Q:
is there a way to install more than one nozzle, say a 35 and 50 shot, so I can switch between the two depending on who I'm runnign against?

thanks!

One more Q:
How important is a heater for the N2O tank? (I live in San Francisco...not too cold or hot). Is the heater mainly to increase pressure when the tank starts to get low...I'm assumign when the tanks full, the pressure regulator will maintain the correct pressure, but as the tank pressure drops delowe the regulator pressure, you'd start looseing the full effect. Is that right?

myGFgottaCIV

yes the fuel line.. is tapped directly from the car's fuel line then goes to the fuel solenoid.. unless you want to run another pump going to the fuel solenoid. and the fuel and nitrous dont mix until its ejected from the tip of the fogger..

now you can have a direct port or even a 2 stage nitrous system.. but as far as two different nozzles jetted differently, it would probably be less of a hassle and more cost efficient to just change the jets in the fogger before racing if you only want two nozzles to be able to switch between say a 35 and 50 shot..

importance of the bottle heater depends on you.. the less pressure, the less efficient nitrous is.. i think up in san francisco.. you're bottle will probably not be at the right pressure very often, especially at night. those bottle warmers get pretty hot.

i was told since i live in cali that a bottle warmer isnt needed since its very hot in the summer now but in the winter it would be good to have.

Not true.

Is this a wet or dry kit? Venom VCN-1000 Honda Nitrous System available on Ebay.

^^^^ Interested in this system but I need to find out if it's a Dry or Wet kit and the seller doesn't know himself, Can someone help me out?

Looks like a dry kit. No fuel solenoid is listed in parts description and says it controls stock injectors to add fuel. Not an expert on this topic. but I think you would need a high flow fuel pump and bigger injectors to run this system safely.

OK.. so here it goes ... My built motor should be finished this week ... I am building a turbo setup but I'm already running a Zex 75 wet kit and have been for about 2 years ... Here is my question.. If I want to run a 100-150 shot what would be required??? Here is the current setup ...

D17a2 sleeved and bored to 77mm with blockguard installed
Eagle rods
Diamond 77mm forged pistons 9.1:1 CR
Polished stock crank
Crower Reground cam
PnP head with stainless valves
Custom head gasket

I know the stock intake manifold wont pass but what about ignition timing??? And for the fuel question ... I already have emanage installed but it is currently running on all stock settings ... Any ideas??? Don't know how plausible the idea is but my brother asked and now I'm a little curious ... Any takers?

myGFgottaCIV

do you mean with or without the turbo? well.. if you do it.. your best bet is getting it tuned on a dyno.. i would suggest retard the timing and going direct port. also think about fuel delivery thats your biggest issue i would think.. if your turbo'd you might want the nitrous on its own fuel pump depending if you've got big boost or not

NashVegasEX

iTrader: (1)

ok ... I was saying nitrous alone .... and your best bet with ANY major performance mod is to dyno tune I know .... And yes, I also know that for anything over a 75 shot (they say 55 but Ive been spraying a 75 with no timing change for years) you have to retard timing, but what I'm asking is can that timing change be accomplished with emanage ... I know it can on a turbo setup but I have no idea where to start when trying to run a huge nitrous shot and adjust ignition timing ...

myGFgottaCIV

^^^ i wouldn't know where to start either.

myGFgottaCIV

oh i might be selling my nos wet kit in a week or two if anyones interested

civicdragster02

I have a question i bought a dry system for my 02 lx and then found out about our fvcked fuel system in your opions would it just be better to get a conversion kit and make it wet if so what do you have to do to the fuel sys to get a wet kit to work 55 shot

honda guy

i have a 2000 civic i been runing the dry zex kit for 3 years now and have not had one problem with the eninge at all.started with the 55 shot for a year then took it up to the 75 shot
