Default What actually makes the sound....

... from the engine when you are say in 5th gear at 45mph. You floor it or goose it, you hear a sound, almost like air rushing but not exactly. Just wondering what exactly causes this sound? I thought about air in and out of the motor but your rpms arent exactly climbing fast since you are so low in the gear.



I would search but this is such a dumb question lol.

its air trying to rush in because you opened up the TB all the way........it creates a High Vacuum in the manifold.....which sucks in anything it can get...from many different spots...

I dont like to band aide things. Just incase it is a problem. I dont usually floor it in 5th at 40... just something I have noticed when I was casually cruising and shifted to 5th instead of 3rd while conversating. He said PUNCH IT, I laughed and said ok.. did that and heard the "air sound". The engine just gets louded but the rpms dont/cant rise even remotely quick.

FWIW on your louder exhaust comment... I have LTs and a ORY. Its loud enough for me

I think I know what sound you are talking about. It's almost like a popping/clicking noise. Like if you "click" your tongue real fast, if you know what that means LOL. I HATE punching my car at low RPMs unless I'm in first cause it makes that ******* sound.

Yeah i dont think its a click... well... no i dont think its a click. It just sounds like the engine is working extra hard, but the rpms of course cant go anywhere. Which is why i wonder what MAKES the sound since it isnt physically spinning faster. So in turn, it cant be moving more air, can it? Because thats what it sounds like...
