WOT noise *

[spoolinturbo]

not sure if its just physics, maybe restrictive intake but it doesnt sound like it.

Under WOT at high RPMS, I hear this high pitched oscillating noise. Sounds like a slipping drive belt but no symptoms of it. Its weird...any of you get that noise : its pretty annoying, even though its loud I hear it and thats what matters haha.

I have heard it too. The noise went away when I took the resonator out of the intake. Go figure.

I know at around 5700 the 3400's used to change pitch, it sounded like valve float.

interesting, very interesting...a task for me on saturday.

yea I have yet to look into our head design, this is my first domestic car so I have some catching up to do in how they do things.

I remember that!! My sister had a 00 Grand Am GT that she had me look at that made a funny noise like you explain around that range.

The noise you are speaking of though happen regardless of RPM range. You could be sitting at a light and slam the gas pedal and be at 1500rpms and here the noise. I think getting loud exhaust + loud audio + loud intake will solve your issues. That may solve my sunroof rattle issue, too! :mrgreen:

hmm i only hear mine at high RPMS, i think...now i am second guessing myself. Yea I am looking for the intake resonator post to see what ya'll did, still looking.
and with all that noise I cant hear my cell phone ring haha. But im deaf from the flightline anyways

Here ya go. Scroll down to like the 4th post- explains where it is. Pretty simple.

Definitely try taking the resonator out, you should see how tiny the air hole is in that thing, I'm sure the sound is just the engine choking to death at high RPM's trying to suck through more air than it can.

awesome guys, we should make that one thread a sticky in the how-to section?

This isn't the case on the 3.9 too is it? Because with my intake resonator removed, at WOT the car sounds bad@$$!

[LoJac963]

I'm sure its even worse on the 3.9 since its a larger engine sucking in more air since I think the stroke of the 3.9 is longer?? Anyways moral of the story is get the resonator out and let the car breathe easier, even if you leave the stock airbox get that resonator out. It would be like us trying to breathe through a straw while running around the block.

ive done that, for 10 miles before...i was ok...until i lost my straw but ours were like the coffee stir straws all like pin hole and crap...good times.

Sounds like some memories of mine in College.

[g6player]

so is the whistle bad or good?

Old thread revival. This is one I cleaned too! It's a whistle, neither good or bad.
