thought i posted in the right spot sorry....but ya i read a lot about it,wondering if other same size throttle bodies makes it also?,some say yes some no....wondering if i should take a chance on another brand,and if anyone here has one,tired of people asking what that noise it..lol
 
My 75 mm BBK throttle body is so loud.....I hate it ...I bought a new SVE 75mm TB didn't install it yet hoping that it doesn't whistle anymore..

I was on the phone with an AM salesman and he admitted the LRS and American Muscle both use the same production facilities in China, haha.. I'd say almost for certain you're in the clear..

I too am running an Accufab throttle body (70mm) and no whistle. They're a little more expensive than most, but hands down the best made throttle body available for our cars. Once piece billet, machined to perfection and polished to a mirror shine.

I had a BBK 75mm on my 4.6L a few years back....and really couldn't tell you if it whistled or not, because the sound of my blower wailing away on top of my engine would have drowned it out anyway.

I've only ever had one throttle body that whistled. If I recall correctly it was a summit brand. I spent some time smoothing the edges of the throttle plate, as well as smoothing the courts for the IAC. once I did that, the whistling went away.

The BBK that is on my car right now does not whistle at all, and never has. My car idles at about 700 rpm.
