Nitrous-wet or dry?

im thinking about putting a bottle on my bike but im wondering weather i should go with a dry shot or a wet shot. the dry shots i have seen look pretty poorly designed. they just shoot nitrous into the air box and rely on the sensors to adjust the a/f ratio. it seems like that kind of set up wouldn't be too concistent.
im also considering going with a wet shot but that seems more like the " to the wall" set up. im not going to run too big of a shot so im wondering if a wet setup will be overkill. what are some good kits i should look at? im sure either way will benefit from a Power Commander but is there a kit i can run without a PC for the time being without leaning my bike out too bad?

why shoot nos into the bike? most people already have a hard time keepin the front wheel down.

btw, wet shot is more safe than dry shot. dry shot is usually more of a " to the wall" kinda setup.

also remember, most bikes are very high compression and high revving machines....doesn't take much to blow that sucker up.

wet = mo' safer , easier to tune without management system / 'puter.
dry = totally ok too if you have fuel management system to introduce mo' fuel when needed.

I wouldn't suggest either one for an engine that hasn't been built for nitrous. Nitrous is the easiest way to send your connecting rods through your crankcase. Forged pistions are a minimum, along with with beefier rods and rod bolts to ensure reliability.

most assuredly dont run it on a stocker if you dont know how to tune . I have run spray on lots of "stock" innards, just dont overdo it and always keep a good "fat" tune.

nitous 101:
you must introduce equal amout of fuel to no2 ratio or youll burn a hole in a piston. no2 is not flamable on its own, it is a stable aclerant, so if you add nos you must add more fuel, those people who think they can just add dry nos to a stock app with no fuel are wrong.

on your aplication a dry shot is more stable.
three ways to do it:
add more fuel with a power comander
add more fuel with a yosh box to the stock computer
the above options will make it run fat all the time.

or you can add an instant rich box.

your fuel system must be working good also, so for high milage you need to change your fuel filter.

on your 02 750, a .20-.23 jet wold be the largest I would run.

I've got all that if you want to play with it.

oh yeah, nos is on for short bursts of HP, 9-14 seconds max. It is a common misconception that it adds hp all the time. mainly used for a competitve edge, when you need that burst to win a race.

Josh is definitely a good resource for this. It depends on the bike and what you are using it for though.

+1 to Josh.
Definitely run dry.

Another way of "enrichening" the circuit is if you have a Power Commander.
Before you run someone, you can hold down the 3 buttons on the PC and put it into "program mode".
Enrichen the mid and top level ranges and you'll be o.k.

I've got a lot of street racers that have been running this way for a LONG time, with no issues.

One caveat, if you have a GSXR1000 I don't recommend spraying it with stock pistons. The distance from the top of the piston to the first ring land is pretty thin.
The sudden increase in cylinder pressure caused by nitrous can collapse the ring land and not allow the ring to "float", which will then scar the cylinder wall.

i can't tell you how much it frustrates me when i try to tell people nitrous doesn't burn, it just supports combustion when you add more fuel. a stubborn friend of mine kept incisting that nitrous burns so i held a lighter up to my tank and cracked the valve. go figure, nitrous blew the flame out.

so what kind of hp increase should i expect to get .20-.23 pill? i just put a new motor in my bike and i would like to get at least a season out of it. so far i think im just going to go with a dry setup and a PC. i think it would be about the same price as a wet shot and it would probablly be easier to hide the system with less solenoids.

so when you put the PC into "program mode" it switches to a diffrent map for the nitrous run right? what would you say would be the biggest shot i could safely run?

It runs the same map, you're just adjusting it richer.
I'd run the smallest it comes with.

20-40 hp dependant on bottle pressure. I have an instant rich box, I have held it in top secret status, but since I quit draging bikes I'll give up a few of my secrets, you are welcome to use it to try it out. What it does is act just like a wet shot, but safe. It hooks to your injectors, and when your no2 switch is activated it puts your injectors to full rich. That way your all motor map is intact, and you are running top HP on motor, then you add no2 HP. I have a whole dry kit if you need it. A wet shot is kind of unstable on a bike, a wet shot can puddle fuel and back-fire, blow the tank off, and guess who is streched across the tank, I have seen it happen more than not.
