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? Thanks.
