I have a question about my car, and im hoping the problem isn't my turbo. I'm boosting a 2000 civic SI w/ a greddy TD05, set at 6psi. as the rpm's raise, i can hear a slight, low whistling sound, and it gets louder as the rpm's climb until the rpm's are so high that the engine covers the sound up. i dont think its my bov, and i dont think im losing any power. i just wanna make sure its not my turbo kit, and hopefully its just the engine making a noise. has anyone had this problem or heard any similar problems like this? please help if you can! Thanks!

 

could be a leak i the charge pipe

 

sounds like boost leak....
