But it is my understanding that the Oxygen comes from the N2O itself, and not from outside. This being the case, wouldn't a shot of Nitrous Oxide from a container + the shot of fuel from the fuel solenoid = a set mix, regardless of altitude? We are discusssing strictly the N2O system performance, not the engine performance in its naturally apirated state. Basically, his point is that N20 performance gain will differ with altitude, whereas I believe the N20 gain will be steady at any altitude, only the engine itself will vary when not receiving a shot of juice.
The reason for our debate is this: I figured that an engine pushing the edge of the envelope on a nitrous bottle, in terms of tolerance, at sea level, would ultimately allow a bit more at say 4000 ft. While our ultimate conclusion is similar, his
reasoning is that the nitrous ALSO makes less power at higher altitudes, AS WELL AS the engine. His thinking calls for more nitrous than mine does. See, me, I understand that the engine itself will produce less power at higher altitudes, but the max safe N2O injection would be only
slightly higher than it is at sea level, and not "a lot" higher than at sea level like my buddy professes.
I guess we are trying to figure out how to stretch the envelope of N2O tolerance as much as possible, even though none of us even run the stuff, lol!
