Whistling at 4200 RPM

[Protege2ner]

When I hit 4200 RPM or there abouts, I hear a whistling noise...What is it? Is it normal or are my pipes or something coming loose.

 

[Notorious]

your turbo probably. are you stock?

 

[FC3s Boy]

sounds like boost bleeding out from somewhere

 

[tekkie]

does your car seem to pull much better after the whistle? it sounds like the turbo just gaining power

 

[JONBOY688]

tighten ure supercharger belt lol just picking. if u got a cold air kit its just the turbo sucking in more air and u can here it.

Same thing happens with my car. I don't worry about it cause I've got the power of warranty.

 

[Kooldino]

It's that WOO WOO

You know what I'm sayin?

the whistles go WOO WOOOOOOOOOOOO!

Huh? wait a second.....we have a warranty? You mean to say that the mark-ass service department bitches at Mazda will actually fix my car rather than say "unable to reproduce problem at this time" or "you abused your car....too bad"???

 

[tekkie]

lol

 

[terbow]

mine does it too. i hope its not leaking already lol. its best heard in 2nd gear 3/4 throttle after 4k. its loud. sounds like a bottle rocket.

Mine does it too. But there's two of them, one is the turbo spooling that i know of, but the second is more like a constant faint squeaking comes in at about 4k rpms at any throttle posistion and is pretty constant. Even if I rev the car while in Nuetral and hold the throttle at 4k it'll make the same squeaking but i can't seem to locate it... Any ideas???

ROFL. I'm not the only one that's seen that

 

[terbow]

lol i remember that news report, that was a riot. woooo wooo

on a serious note. i can hear it sooling, its faint but it goes away and then its loud. i havent tried troubleshooting it, i just noticed it happening the last few days.

main noise is just the turbo taking in air...the secondary noise may well be a leak...mine leaked and sounded like a high pitched hiss...

 

[terbow]

mines definately not a hiss. its loud, like a squeeek.

 

[Protege2ner]

its bone stock with about 14k I'll check the pipes, the damn car hasn't been right since I took delivery. Never had any problems w/ my RX.

 

[terbow]

i only got 4k miles.

 

[FSDET]

i have it too but it seems normal ?
but recently ive had this wierd noise.. its at about 3k when the turbo start spooling.. its like burrr (not like the turkey its a deep noise ) and it only last for like a second ???
i think its the CAI leaking ?

 

[terbow]

i think its normal, im not sure though. its my first turbo car. I heard it on the dyno too and they didnt say it was bad. they said it was the turbo spooling (i can hear it spooling, its much more faint but maybe its louder when the gate opens or somethin, or when that vics or whatever happends cause theres more air goin in?)

i dont think its bad, im not worried. i was just mentioning i have it as well.

The loud sound is the intake sucking in air but the whistle you hear around 4000 RPM and more is the turbo spinning. When youre gradually uping the RPM more air are going thru the exhaust so the turbo spin faster and faster thats why youre hearing that whistle around 4000 RPM 'cause thats is where the turbo is starting to spin DAMN FAST (rockon) !!!!!!!!!!!!!!!
So dont worry everything is fine, in fact I found that sound pretty sweet when youre window is open !!!
