Im designing a small n2o system for my 440cc 2 stroke engine. I was planning on having two fan style foggers spraying towards the combustion chamber (w/ funnel jets), placed in the intake boot after the carburetor (on each side). But, when either piston reaches TDC, nitrous would be sprayed into the crank case. Is this bad? Or something that I can just ignore. Im thinking about if it could somehow eventually deteriorate the diaphram in my fuel pump, if it got into the vacuum line (then again, its not corrosive..). After a few revolutions of the crank would the n2o eventually break down and be harmless? I know this is a waste of money, but I have nothing better to do. Anyone think that this will be a problem?

 

I believe Nitrous Express makes 2 stroke kits...check into them. As far as the nitrous going into the crank case, I don't see a problem with it..nothing is combusting down in there.

 

I looked into NX's kits, as well as Holly's N.O.S. kits. They are pretty pricey for me, I would be saving a few hundred just making my own kit. Basically, the setup would be:

[Fogger]----,
................ [Y Fitting]--------[Solenoid]-------[PSI Gauge]---[10oz Bottle]
[Fogger]----'

I think a 12v 30a battery should be sufficient. Right now, my total cost is around 200. Ive seen some of the kits up in the 700's.

 

Anything? :happysad:

 

eh?

 

crop that pic damn it crop!

 

Sorry :happysad:

Anyways, any opinions?

 

You could do a setup like that, but what kind of activation are you going to have...a throttle switch? At least use the jetting from one of the 2 stroke kits, so you know it's properly sized.

 

At first, just a momentary to test it out a few tries. Then i'll figure out what i want to do. I think when I order all the parts, i'll call up NX and ask them what size jets they would recommend, or which size comes in their kits. I could allways order a few sets, start small, and move up a size or two.

 

I would call them and ask about jetting rather than moving up yourself. It won't take much nitrous to feel a big kick on a motor that small, so going up jet sizes should be done cautiously. You could get the throttle switch that NOS sells with their kits, and somehow rig it to the throttle tube, or have it on a push button momentary all the time like you said, along with an arming switch.
