Hi Everyone. Curious if every engine with manual trans experiences this. If I have in neutral and parked and blip the throttle fast there is a suction or rub noise from under the hood as I do that. And I could even say a slight hesitation with it. If I gradually throttle it, no sound. If I am driving, I don't hear nothing under load.

Anyone notice something similar or know why it does this. If anyone could open hood and listen as they press throttle and let me know itd be much appreciated. Just go this baby yesterday. Thanks!

That is your stock cold air intake sucking in air, you will hear it from the passenger side front.
I love that sound.

Thanks! It makes the car hesitate though a little, no?

I am in North Wildwood today, when I take it out for a cruise I will blip the throttle to check.

I am pretty sure with no load on the engine, there is a slight hesitation before you get that cool intake sound.

When you have load on the engine during driving (when you are in gear) it is instantaneous.

BTW, this happens whether you have a manual tranny in neutral or the automatic in neutral.

I have the automatic.

Thanks Yell03. Last night I was running the car around and it didn't hesitate. It must have been bc it wasn't at temperature yet or low idle. Anyhow, let me know what you notice. The hesitation was only when I pressed the rattle quickly from idle rpm.

Hi,

I have 750 miles on my C7(manual tranny) and I also noticed this noise.

Here is a video:

I´am sure this noise was not before 700 miles?!?

Intake sucking air. Normal.

Thank you, Jeff.
My C6 Ls3 did not sound like that...
