Cubic inches and nitrous question
Cubic inches and nitrous question I was told that a 300 or 400 shot of nitrous would be a waste on a smaller cubes motor (347ci or 370ci). If I have a 347 cubic inch motor and I spray a 300 shot on it would only ~70% or so of the shot be effective or would it be 100% effective regardless of the amount of cubic inches?
Thanks for any info on this..

I offer that there are limits to how much nitrous a given displacement can take at a certain RPM. So, the idea of what they are saying is not wrong. It is just what the practical levels are for your given combo that is debatable. I will say that the power per lb of nitrous does decrease as you increase the size of the shot as you approach that threshhold.
And just remember, you will not pick up twice as much on a 200 shot as you do on a 100 shot. And, as the shots get bigger, this disparity increases.

I agree with the "there is too big of a shot" for certain engines. Like your not going to put a 300 shot on a crotch rocket or a Honda civic or a pro mod shot on a 346. But the shots that he is mentioning I know of on a few built 346/347s.
So if you meant by your question is there too big of a shot for a 346/347 I believe there is. If you need a 500 shot to go as fast as you wanna go, you may wanna go with a lil more ci haha
VE changes when you introduce a power adder.
Yes , but, VE of a nitrous motor will not equal a turbo or supercharger engine because nitrous engine is at atmospheric manifold pressure unlike a forced induction engine. I am sure the size of the cylinder has an effect on how much an engine can ingest in addition to some other factors already mentioned like the total combination of cylinder head, manifold, camshaft, rpm.

I would agree with most everybody's reaction to the OP's specific question that you cannot impose that arbitrary limit on the 5.7's abilities. However, the this topic does provide a great opportunity to discuss the limitations displacement puts on the amount of nitrous and fuel that can be burned effectively.
