NOS system Paintabll gun on a 2 stroke chinease motor

Ok guys so i wanted to build something similar to the Nos system they sell for the 2 stroke engines out of a CO2 paintaball cylinder and its expansion chamber.

So far i have the tank which is approx at 3000 psi the fitting where the tank screws in and a steel braided hose 7" long with a 1/4 npt fitting at the end.

What i'm trying to figure out is an inexpensive way to control the flow of air from the tank into the intake.

I guess it could be manually or with a 12v solenoid capable of handling 3000 psi.

Any ideas??
 
Just wanted to know how NOS would help unless your putting more fuel into the engine also. I believe it would just lean out the engine.
 
Not really, I mean as long as the port is on the intake side of the carburator and the carb is set to run on the rich side. According to my research as long as the nos jet is not on the intake tube there should be no problem.

I just wonder how long one of these little Chinese hand grenades with last with a NOS shot. I could be as short as once and done. These motors don't have the quality components it will take to hold up very long under the strain of nitrous. We have all seen the QC issues these motors have. I wish you luck though and I hope it works the way you want but I have my doubts.

Again good luck. We will all learn from your project so please keep us informed.

C02 will NOT do the same thing as nitrous. C02 will EXTINGUISH fires...nitrous (N20) HELPS fires burn like oxygen does and it comes out of the bottle at about negative 127 degrees F. This cools the intake air charge by about 65-70 degrees by the time the nitrous gets into the engine. You MUST HAVE an extra fuel source to run nitrous, just running the carb rich will work, but not for very long.
a 350 horsepower engine with an intake temperature drop of 70 degrees f, would gain about 25 horsepower just by the cooling effect. add nitrous and the nitrogen buffers the cylinder pressures which leads to more controlled combustion and huge horsepower increases. the added fuel that is injected into the cylinders is burned rapidy by the help of nitrous, with a very low air intake temprature charge. an engine that is sucking in cold air will make more horsepower than an engine sucking in hot air. but you have to have added fuel to make big hirsepower increases. ANY engine will make more horsepower when the air temp outside is -30 F rather than 80degrees F. the benefit of nitrous is the abilty to add more fuel that what the carb supplies, and the nitrous is like spraying pure oxygen onto to a blazing bonfire.
In order for nitrous to truly be effective, and for your engine to live, you have to add extra fuel besides what is being sucked into the engine from the carb. you have to have a total secondary fuel source (like a solenoid with a jet in it, and fuel under pressure that can be injected into the engine).
3000 psi of pressure is WAY too much pressure to shove into one of these little 2 stroke engines.
a typical nitrous set up on a v-8 is injected into the cylinders at only about 800 psi, which is set using a regulator.


your idea will never work.
if the 3000 psi doesn't blow the head off the cylinder, the 3000 psi will just stop the piston in it's tracks and probably bend the connecting rod.

Are you thinking there will be some extreme power boost when you run it?

I do believe that the CO2 will indeed kill the engine as it will reak havoc in the cylinder as opposed to the flammable nitrous....

Science my boy, science

nitrous is not flammable. Nitrous helps FUEL burn faster, like oxygen does. you can not light nitrous oxide on fire without a fuel source.
just like adding oxygen to an already burning fire.
watch the old movie "backdraft" when there is a smoldering fire in an air tight room, as soon as the door is opened, and oxygen is added to the room, the smoldering fire explodes.
Nitrous works in the same way.
 
Ok, well i wasn't planning on shooting 3000 psi into the combustion chamber. Thats not too bright. I was going to put a small nozzle that would restrict the flow of the 3000 psi into something manageable that would yield some power increase.

So for all of those bashing my idea:

How come people rig an Ultraflate kit which uses disposable high pressure co2 cartridges onto their pocket bikes and motor bikes burst it a couple time while doing top speed runs and have great results?

The only difference is that I am not using a Ultraflate that has been re-branded with a "NOS" or "BOOST" sticker which actually contains CO2.
I am using a canister capable of greater capacity and use between refills.

Why does the Ultraflate work and my idea won't work? :bowdown:

FOR THOSE OF YOU WHO BELIEVE NITROUS IS FLAMMABLE TRY SPRAYING IT ONTO A OPEN FLAME AND WATCH IT GET EXTINGUISHED...NITROUS IS NON FLAMMABLE!
