A high velocity stream of air would create a Venturi Effect (take fluid dynamics 101) which would make air induction easier (like what a supercharger does).


Several problems with your thinking.

100psi of air in sufficient volume would wildly overwhelm the engine's ability to ingest the air and the majority would back flow out the filter.

That in effect would cause the MAF reading to drop and the engine to be instantly destroyed from going deadly lean.

Though depending on the size of the air tank you use the volume may be so small it doesn't make a difference either way except to lean out the engine and yet still cause damage. (Basically a self-induced intake leak )


You see the engine just will not pull in more air then it's natural CFM draw just because you shoot air into the intake.

There is a reason that a super or turbo charger literally "caps" the intake to achieve boost. Only one way for the air to go and No reversion. Well besides when the throttle plate closes but that's different.

If you want to use nitrous as your example. Nitrous makes it's power from it's increased oxygen percentage and ultra cold temperature. It still requires the engine's natural pulling ability to draw it into the engine.


So your thinking and theory is not very sound at all.

Also the "venturi" effect does not remotely apply here so don't even bring that up.

Also while we are at it. Explain the supercharger equals the venturi effect comment?
