Venturi tubes

[mndude07]

Some corrections about the venturi.

It runs at a lower pressure/higher velocity IN the restriction.

After the restriction it begins to slow down to its original pressure/speed.

This phenomemon is a component to how wings work as well as how carburetors work.

In order to maintain the flow through the pipe, the velocity must go up, resulting in a corresponding pressure drop.

Ahh I should have realized that. So a venturi tube on the collector as mentioned will do nothing. However, lets say we have 2.5" exhaust, and step it down to a 2.25" in/out resonator. Resonators slow air flow, but making the air fit into a smaller diameter should create a small venturi effect, and possibly negate the slowing effects of the resonator? I'm probably still missing something here though, because at the same time, the resonator is already a restriction, and more so if you make it a smaller diameter.

Then why have a res. at all?...be pointless to even put an 8" one on there.

And if you do find out if that think helps and exhaust system like mine...let me know.

Not sure I was gonna try them first to see if it helped, if not I'll just leave it.
