The horse power from the kit depends on what nozzle size you use. A WON kit has nozzle sizes from 25-200

Not too mention the excess fuel that should already be there ;). I'll kiss your ass if you make more power in an engine by just introducing nitrous. It has to have fuel atoms to attach itself to and combust. The reason why nitrous works is I don't know of any internal combustion that makes use of 100% of its fuel that it injects. The more the fuel, the bigger the jet that can be used.

Chances are if your smoking out the back, switch the nitrous switch, and it cleans up the exhaust, you found the right jet and wouldn't need anything bigger.:)

Yes you need the fuel there to mix with the oxidizing agent anybody who knows the basics of how NOS works knows that. To find which nozzle is best suited for the fuel set up put the car on a RR and start with a small nozzles and keep working your way larger. When the power stops rising and starts to drop you know you have get to the best size nozzle for your engine. Fit a nozzles to big and the EGT`s and power will drop very quickly and you can start to put out the flame in the chamber and start to make the engine back fire if not careful.

nos is NOT ILLEGAL to have in your car in the US. please do your homework on this and don't spread what a friend told ya.

some states you can't have the line hooked up. it varies from state to state.

also its soooo stupid they even have any laws about nitrous use or the fact its in your car.

next they will ban supercharers and turbos. then it will be the internal combustion engine. oh wait they are on that road already right lol.

For some states its illegal to have in your car. Some states its illegal to have hooked up. Whats the point in having a nitrous oxide system in your car if you can't have it hooked up? It has basically become an unofficial "for off-road use only" modification. Much like EGR deletes, HID balasts in regular headlights... etc...etc... the list goes on.

Nitrous oxide systems are commonly associated with street racing. Engaging a nitrous oxide system pretty much means your trying to race and trying to achieve the most amount of power in your vehicle for a short period of time (aka a street race if its on pubic roads).

Try telling an officer if you get pulled over thats its legal to have. They will dock you for one of two things, racing on the street or attempting to race on the street.

My fathers friend that had it hooked up in his beemer got his license suspended (forget for how much time). Whether this was attributed to the system itself or street racing, it doesn't really matter because the two go hand-in-hand.

like i said it VARIES alot from state to state. and in my state you can have it hooked up last i checked. now that may have changed.

soo since you have a bottle hooked up but not on. you are ready to street race right:confused:.

oh wait we have a turbo/supercharger it can make boost at any given time.soo we are always ready to street race. i mean when we want boost we are trying to make max power for a short period of time(street race as you call it).:rolleyes:

also attemping to street race cause a bottle is in the car? thats like saying because i am driving down the road he can give me a tickect for attemping to speed,street race,road rage,reckless driveing.

kinda like if you have a CCW. and carry a gun you are a attempted murder.hahaha

The only benefit from Nitrous Oxide without adding fuel is the intake charge will be cool and more dense and any unburned fuel will be consumed by the added oxygen.

Adding additional fuel in a diesel is not as easy as adding it to the intake port like in a gas car, the wrong type of fuel or too much will lead to pre-ignition and engine damage.

if you have a tuner add additional fuel in the injection cycle the NOS will add power, but when off NOS you will be blowing fuel (smoke) out the tail pipe. I'm not sure if it's possible to add fuel based on NOS activation that may require hardware changes to the ECM.

I am just looking to get a little more power out of the car, by helping burn all the fuel that is in there already. I have some haze on full throttle so I think I can get some hp out of the NOS?

You should see some power increase but I doubt it would be much.

I am just hoping for 25 hp? Enough to help me on the track :rolleyes:
Only one way to find out right? Buy the kit and try it... too many variables in play to determine how much power it will make.

Every car will be different depending on how "rich" the fuel mixture is. Heavier fueling is going to result in better atomization of the fuel that is already there due to more available oxygen. Since you have barely a haze at WOT and really only smoke on shifts, I doubt there is much to be had.

Now... you could always discuss with your tuner for more fuel for a track ready tune so that you'll reap more benefits with the nitrous. As stated before... you will smoke like a train at any point off of nitrous...

I put the NOS kit from WON about 10 years ago for the TDI Fest in Grand Rapids. I had a set of chips that over fueled so that when I didn't have the nitrous turned on, it was a bit smokey.. BTW, I was able to squeek out 150hp/300tq at the wheels with the Nitrous on (and stock turbo/internals) an ALH motor. Still running well at 128k miles.

You don't necessarily smoke like a train with a N20 tune with the N20 switched off. Your tuner can mod the fuel curve to match the rpm N20 is engaged. Typically N20 setups use WOT activation anyways so heavy fueling at low rpms isn't necessary.

For longevity, make sure to run a N20 filter pre-solenoid to keep crap out of the solenoid after opening line to refill bottle. Also check solenoid for proper function before a run. A bad/stuck solenoid can cause a backfire and blow your intake manifold.....ask how I know :)
