Anyone know how to improve the sound of a closed cold air intake? Can’t hear it at all even with radio volume all the way down, full throttle and head out the window ---

Hmmm, intake that’s too quiet? Sorry no real suggestions. You need a more “wanna be racer” oriented forum. ---

I think you need a 4v carb for that. Then you step it down and all four kick in and you can hear the gas being sucked through after the tires squeal. ---

You can’t improve a quiet air intale. ---

But that would solve the “quiet intake” problem, and get another annoying “wanna-be-racer-boy” off the street. It’s a Win-Win 🤣 😂 😂 🤣 ---

Had a 62 Sport Fury with a 361, cut a hole in the hood, added an air scoop, split the air cleaner housing, rigged it to seal to the underside of the hood. When the secondaries opened up, WOT, I could not hear the exhaust over, what Ross Perot would call “a giant sucking sound “. I my defense 1967, I was 17.
