I did Dyno testing for the last 30 years. It really sounds cool if you are in the room when the secondaries kick in.
Some engines we ran without filters and only a velocity stack, because we could not get enough air to them. The room air was filtered anyway.
Modern F. I. engines make way more power with their stock tuned intake systems with plenum chambers.
But that was another life...
And in many ways, a better life. Cars were different - and fun. Yes, I realize we have better electronics, safety, and convenience features, but modern cars lack personality. And, of course, there's not much tinkering you can do with an engine. Given a choice between my '65 427 and a modern car - no choice - give me modern.
