Air Exclusion Due To Nitrous

Now I know this is not a blower related question.............

In a heavy nitrous mountain motor, I would tend to think that during N2O application a lot of "air" ingestion would be precluded by the expanding N2O in the manifold????

Has anyone out there ever measured, or have seen some data, in this regard?

Trying to help a friend with his nitrous deal, while getting up to speed with it myself.

Any thoughts would be helpful.

 

Turn all 6 systems on and replaced the rings every 2-4 runs

 

I have very little hands on nitrous experience and is the hardest of all the combos to manage in my opinion. A nitrous engine can only consume so much nitrous until it becomes “static” if you will. In the carb days you might hear about the carbs losing signal and it’s ability to make any more power. The amount of nitrous able to be consumed is related in some kind of proportion to the size of the engine. Want to flow more nitrous, make the engine bigger, then make it bigger again. I’m not sure what they are seeing now days with the fuel injection and the map sensor. I do know the move has been towards more smaller kits instead of a few big ones for management purposes. I also know that the later kits hit less, so say you are stacking kits at 300 hp a piece, by the time you get to that last kit it doesn’t hit like a 300, it hits more like, say a 250.

The main issue that I didn’t like is that you can hurt the engine, mainly the top ring from too much fuel. There’s something weird going on with the top ring heat situation but no one seems interested in fixing it, they just become a commodity. If your losing vacuum during the run it’s detonating and fluttering the rings. These are just generalizations as I see them, your results may vary.
