I got my new BBK 80 mm TB yesterday and installed it. The car seems to have REALLY picked up some power . It pulls HARD all the way up to 6600 RPM (that’s where my rev lim is....never hit it before....) before I realize it .

Here is my only problem:

At between 20% and 30% throttle and at idle, I get a whistle sound. Above idle (and below 20 %) the sound is gone, and above 30% the sound is gone.

My thoughts:

I am thinking it is the round hole for the ICS whistling. I have already checked the seal between the TB and the intake (was tight).


Help???

Any idea what that could be and how I could get rid of it?


Thanks,

Chris

 

I think thats pretty common w/ the bbk system, if Im not mistaken the Lt1 system did the same thing..the extra power should outweigh the little noise u pick up

 

it does for me......it would be nice to get rid of the sound also
