Last nite I was driving my car hard. And I noticed a wistle sound coming from the engine when I accelerated. Its not my intake its more of a distinct wistle kinda like a supercharger just not as loud, but loud enough to hear it. The sound is kinda like the sound cars make when they go in reverse fast idk if you guys know what I mean idk what to describe the sound too. Any ideas what this can be? Also the wistle is gone after I shut it off when I got to my destination and when I drove home it wasn't there but I wasn't driving the car hard. Any ideas?

 

Thats your turbo.

 

LOL I wish:p nah but seriously

 

I get the whine too.

Sounds cool but I need to find out what it is too lol

I'm thinking mine is from the heat shield?

 

I know I like it too, makes the car sound a lil more aggresive lol. my brothers 01 Cl type s made the same sound a lot louder than mine tho. It made it all the time.

 

My friends always point out "whoa listen to the engine go!!" and I'm looking at my RPMS and its only 2500 RPMs LOL
