Noise

[jdawg190]

I have read the other threads about the whistling noise that our speeds make and i know its the turbo, but i have had mine for 6 months now and the noise is becoming more noticeable. It use to only do it after 4 rpms but now it does it after 2 rpms. Is this because i got the car flashed? or whats the problem?

I think its ok, i know a bunch of our cars are doing it. Do you have any mods?

sounds pretty bad hows the weather up there? cold? because mine sounds louder whent the car's cold....my cousing told me i had a exhuast manifold leak and should check in for warranty...but others told me its normal any insight on this subject...?

it's normal. the turbo spools up from about 2k and gets even louder past 4k so don't worry too much...if u had a leak u'd notice a real drop in acceleration and power. it would cause the turbo to spool up slower or something

our turbo might spool faster cause of colder weather. right now my car does this: 2-3k rpm does a hisss, 4-5k does a whistle (if my car is hot then this is where i lag), then 5.5-6.5 does a screech(big boost of power about here). i am currently unflashed tho, i dont think i will do it either, cause i want to forge engine to boost higher. but anyways im off topic, but i think the sounds you hear are fine.

yea it could be because of the cold weather. I keep the car outside and it is starting to get really cold here now. I was always told though our turbo kicks in around 4 rpms. I guess the best thing to do is take it in and get it checked out.

Whoever told you the tubo kicks in at 4k is an idiot. The turbo in the MSP is a small one that's set up for minimal lag and good mid range power. It kicks in very low in the RPM range.

you should start hearing turbo around 2k and should feel full force at 3k rpms. our cars are made for quick boost for auto cross and things. not to fly...

turbo kicks in at about 2800 rpms, at 4000 you'll really start to hear it whine though. I've been told by other members that as the car ages, gets broke in and such, that noise will become more noticeable.

And yeah, if it's colder, she spools a lot quicker, so it makes sense you would hear it more in the cold.
