intake wistle...

I have a trick flow upper plenum BBK 70mm throttle body and cold air by BBk.The throttle body wistles and is there anything that can be done about it? Thanks

I also have a Trick Flow "plenum" with the stock tb and the stock air intake tube. Mine whistles, kind of like blowing across the top of a Coke bottle. It's a faint sound, mostly audible at part-throttle.

I'm about as sure as I can be that there are no leaks. I really think it's the design of the plenum that causes this whistle.

:shrug:
 
mine whistles constantly and i love it.....it did it really bad when i had just the 75mm throttle body and stock plenum....then i ported the stock upper plenum and it quit and i was sad....then i sold that and got the trick flow unit and started whistleing again so i was happy....i seen a buddy of mine on the interstate the other day and he calls me on my phone and says man somethings wrong with your car its whistleing at me.....then i kicked it and he said "oh..."

Yes, I took it to ford and it does not have a leak, it is the air by the throttle plate . rushing through the throttle plate. Said it is characteristic. and the stock one has a design for deadning the noise.
